1. Introduction 

1.1 Background 

The London Borough of Islington wishes to develop the Highbury Roundhouse Community 

Centre site, including rebuilding the Centre itself. Atkins has been commissioned by the London 

Borough of Islington to carry out a geotechnical desk study and topographical survey of the site, 

together with a condition survey of the existing retaining structures present on site 

The geotechnical desk study has reviewed existing available geotechnical information to allow 

the key issues to be identified and their implications to be assessed for further investigation. 

In addition, some environmental issues have been included in this report. However, it is proposed 

that a Phase 1 environmental desk study will be produced at a later date which will include a 

detailed assessment of potential sources of contamination from previous land uses. 

This desk study has been undertaken in a limited time scale and covers only the main aspects of 

the site and should not be considered exhaustive. The advice contained in this report should not 

be taken as definitive and may be subject to revision during further investigation works. 

1.2 Scope of Work 

The scope of work comprises: 

• Topographical survey to establish the topography of the site area and to determine the exact 

site boundaries; 

• Undertake a site visit to provide an assessment on what involvement will be needed by 

Network Rail to provide clarification on the use of the land above the tunnel for a 

development; 

• Prepare a geotechnical desk study of the site recommending scope of an appropriate 

investigation; 

• Undertake a condition survey of the existing retaining structures around the site and 

recommend preliminary options for the repair or replacement and a preliminary cost 

associated with the works. 

• Search of the underground utilities within the site boundaries. 



2. Sources of Information 

Information on the geology, hydrogeology, hydrology, site history and contamination within the area 

has been gathered. This has involved contacting various organisations, to obtain existing information

3. Site Conditions 

3.1 Site Description 

The site is elongated, irregular in shape and generally flat. The site is bounded on the northern 

side by Nos. 1 to 8 Whistler Street, on the eastern side by Nos. 1a to 31 Battledean Road, on the 

southern side by Ronalds Road and on the western side by a railway cutting. The site is narrower 

in the central area where there is a constriction formed by the top of the railway cutting and the 

properties along Battledean Road. 

The Highbury Roundhouse Youth and Community Centre is located at the northern end of the site 

backing onto the properties of Nos. 1 to 8 Whistler Street. Another property, No. 71 Ronalds 

Road, is owned by Highbury Roundhouse and is located at the entrance to the site. The site also 

includes an area above and immediately to the west of the railway tunnel at the southern end of 

the site, the ownership of which is currently uncertain. The majority of the remainder of the site is 

covered with tarmac. 

On the western side of the railway cutting, the cutting slopes are used for allotments. On the 

eastern side of the cutting, the cutting slopes are used as a recreational area (woodland walk) and 

to the north by a gardening group. 

3.2 Topography 

As stated above the site is generally flat. Bench marks near the entrance to the site indicate the 

ground level to be around 41mOD. The ground falls away on the western side of the site as a 

result of the slope to the railway cutting. The ground rises away from the eastern side of the site 

towards Highbury Fields. A retaining wall forms the boundary on the eastern side of the site which 

retains the gardens of Nos. 1 to 31 Battledean Road with a retained height of around 2m. 

3.3 Site Boundaries 

Atkins has made initial enquiries with Network Rail (York office) in relation to the outstanding issue 

of land boundaries/ownership, particularly with regard to the area of land above the CE of 

Canonbury Tunnel. It is believed that NR have existing access rights over the D/S cutting slope, 

particularly adjacent to the CE tunnel portal and LE elevation of Drayton Park Bridge (at the North 

end of the site), for the purposes of undertaking structure examinations and maintenance works. 

3.4 Underground Services 

Atkins has made preliminary enquires to key statutory service providers which may have 

plant/apparatus located within the site. Details of these statutory providers are summarised in

4. Site History 

4.1 Historical Maps 

The Envirocheck Report obtained from Landmark Information Group includes historical Ordnance 

Survey maps of the area ranging in scale from 1:1,250 to 1:10,560. The maps have been 

summarised in Table 4.1 in order to present the site history. A selection of the historical Ordnance 

Survey maps together with the current Ordnance Survey map showing the site location are

5. Geology, Hydrogeology and Hydrology 

5.1 Geology 

5.1.1 Published Geology 

The British Geological Survey (BGS) Sheet 256 North London dated 1994 shows the site to be 

underlain by London Clay. However, the earlier published map dated 1904 shows an area of Boyn 

Hill Terrace Gravel on the eastern side of the site and either underlying the footprint of the Youth 

and Community Centre or immediately adjacent to it. The justification for the re-mapping of the 

geology on the later map is unknown. 

5.1.2 Previous Investigations 

The BGS was contacted to locate any existing boreholes in the vicinity of the site. Details of two 

previous ground investigations were identified as discussed below. The borehole logs are 

provided in Appendix B. 

GLC ILEA – Whistler Street 

A ground investigation comprising nine boreholes was carried out by the GLC ILEA in 1974. Four 

of these boreholes (BHs 5, 6, 7 and 8) are located on the railway cutting slope adjacent to the site, 

with BH7 located on the slope close to No. 1 Whistler Street and the Youth and Community 

Centre building. BHs 3 and 4 are located on the area currently occupied by the Community 

Garden at the top of the railway cutting. BH9 is located on the south side of Ronalds Road 

opposite No. 71, occupied by the Highbury Roundhouse. The remaining two boreholes are more 

remote from the site. The boreholes were taken to depths of between 15 and 20m. 

All the boreholes encountered London Clay below either topsoil or a thin layer of Made Ground 

Proposed Victoria Line Underground Railway 

A borehole (BH118) is located immediately to the north of the railway cutting in Whistler Street. 

The borehole was taken to a depth of 90 feet (27.4m) and encountered London Clay over its 

whole depth. 

5.2 Hydrogeology 

The site is underlain by a non-aquifer, ie the London Clay. 

5.3 Hydrology 

An aqueduct, the New River, which was commissioned in 1613 to bring drinking water to London 

from Hertfordshire is located approximately 1km to the south-east of the site. There are no other 

water courses within 1km of the site. 



6. Ground Conditions 

The ground conditions at the site, based on the closest existing boreholes and the published data, 

are likely to comprise the following: 

Made Ground 

Weathered London Clay 

London Clay 

6.1 Made Ground 

The Made Ground is likely to be around 0.5m thick comprising brown clay with ash and brick. 

6.2 Weathered London Clay 

The weathered top of the London Clay is firm becoming stiff brown fissured silty clay. The depth of 

the weathered layer was found to be between 9.8m and 11.2m below ground level. No in situ tests 

were carried out in the boreholes, however, based on the borehole descriptions of the clay, an 

undrained strength of 50kPa can be assumed at the top of the stratum increasing with depth. 

6.3 London Clay 

The London Clay comprises very stiff grey-brown fissured silty clay and was found to the 

termination of the boreholes at a depth of 20m. Based on the borehole descriptions, an undrained 

strength of 150kPa can be assumed at the top of the unweathered London Clay. 

6.4 Contamination 

The presence of any contamination from previous land uses has not been considered in this desk 

study. 



7. Fieldwork 

7.1 Walkover Survey 

A walkover survey was carried out by a geotechnical engineer on 16 February 2009 and the 

findings are given in Appendix C and summarised below. 

The tarmac or concrete surfacing, in particular near to the Youth and Community Centre is uneven 

and cracked. There is an area along the length of the west side retaining wall that has been 

fenced off and has pronounced cracking approximately parallel to the wall. The west side retaining 

wall only retains a small height of fill (less than 0.5m), although the wall is around 2m high. A 

telegraph pole within this area close to the wall is leaning towards the cutting. 

The east side retaining wall is greater than 2m in height, is cracked and leaning and has been 

buttressed. This wall retains the gardens of the properties along Battledean Road; assumed 

retained height of 1.5 to 2m. 

The condition of the retaining walls is discussed further in Section 7.3. 

The Youth and Community Centre shows signs of cracking in the walls which is likely to be as a 

result of subsidence. Trees are located immediately adjacent to the west wall of the Centre along 

the top of the railway cutting. 

The walls of No. 1 Whistler Street, No. 71 Ronalds Road and the railway tunnel have all been 

anchored or tied back as a result of structural displacement. 

The railway cutting has a gradient of between 1:2.5 and 1:3. The surface of the cutting slope is 

cohesive with evidence of a small amount of orange-brown granular fill below the west side 

retaining wall. No evidence of slope instability was observed. An embayment has been cut into the 

slope for a seating area below the west side retaining wall. The slopes are covered with semimature 

trees. The toe of the cutting is supported by a sheet piled retaining wall. 

A greenhouse has been constructed on a terrace cut into the slope near to the top of the sheet 

piled wall. The brick wall retaining the cut is cracked and is displaced towards the railway. 

A new brick wall is currently under construction along the west side of Whistler Street which ends 

at the north side of the Youth and Community Centre. 

7.2 Topographical Survey 

A topographic survey of the site has been carried out excluding the area above the tunnel. The 

survey plan is given in Appendix E. 

7.3 Condition Survey of Retaining Structures 

The site consists of an area of land at the top (crest) of the D/S railway cutting slope, known as 

‘Highbury Roundhouse’, the graded cutting slope down to the railway line (Olden Gardens) and 

area of land of the over the CE of Canonbury Tunnel (between Ronalds Road and the CE tunnel 

portal) – refer to site plan in Appendix A. 

Within the site are a number of retaining wall structures, which provide support to the cutting 

slope material, allowing the development of the land at the top of the slope for commercial 

premises, and later use by the local community. 

The retaining wall structures inspected as part of this desk study are: 

West Side Retaining Wall – Formed of mass brickwork construction with flat concrete coping 

stones, approx 2.2 metres in height, with an approx. thickness of 330mm (above retained ground 



level), is situated at the top of the cutting slope, adjacent to the surfaced car park area in front of 

the Community Centre building 

East Side Boundary Retaining Wall - Predominately of mass brickwork construction, but 

punctuated with sections of insitu concrete walls, The wall is of a constant height of approx 2.2 

metres above the adjacent car park surface, originally constructed vertically, with brickwork 

buttress walls, retaining the rear garden material of the properties fronting Battledean Road 

Olden Garden Retaining Wall – A low level, brickwork retaining wall, providing a recess area at 

the foot of the D/S cutting slope for the erection of a community greenhouse 

Community Centre End Wall – Forming part of the ‘original’ building construction, and providing 

support to the gable end of the main roof structure. The wall appears to be 225mm thick at roof 

level increasing to a thickness of 330mm at the base, with an arched window at ground floor level 

and 3 No. further window openings at first floor level. 

Representative views of the site, along with the retaining wall structures are given by photos in 

Appendix C. 

7.4 Summary of Site Condition Survey 

The site Condition Survey was undertaken by Atkins on 20.02.09, using a ladder, where 

necessary, noting the visual defects within the retaining walls. A series of plumb readings were 

taken to determine the approx verticality of the walls at varies locations. 

The weather conditions were ‘dry’ at time of inspection. 

No archive drawings or historic information is available, showing hidden construction details and 

understanding of such details will therefore be relied on the undertaking of trial pit/core survey 

work. 

The Condition Survey concluded that all 3 No. retaining wall structures including the Community 

Centre end wall, are in a poor condition, with the following items noted: 

West Side Retaining Wall 

i) Significantly forward leaning/rotation of the wall out of vertical ‘plumb’ profile, along the total 

length – refer to site sketches in Appendix F for verticality readings. 

ii) 

iii) 

iv) 

Mature ‘unchecked’ buddleia growth through mortar joints within brickwork, causing 

significant damage and displacement 

Additional mesh fencing installed along the top of the wall, increasing the lateral instability of 

the wall 

Deep open mortar joints, particularly, to the low level (trackside) face of the wall 

East Side Boundary Wall 

v) Vertical fractures, typically, close or adjacent to the buttress walls 

vi) 

Significant forward leaning (top over base), along the length of the wall 

vii) Upper section of the wall sliding over the base (at DPC level) in the ‘newer’ section of the wall 

(towards Ronalds Road end) 

viii) Section of the wall has been reconstructed on the ‘original’ wall footings 

ix) 

Evidence of blocked weepholes at the base of the wall 

Olden Garden Retaining Wall 

x) Vertical fracture (full height) at the centre of the wall with forward displacement, either side, 

towards the track 

xi) 

Vertical fractures within the mitre corners between main wall elevation and side walls 

Community Centre End Wall 



xii) Diagonal fracture (within the track side elevation) extending from the extrados ring of the 

ground floor arch window, down to the corner of the building – visible externally and internally 

xiii) Wall constructed along the crest of the cutting slope with evidence of vertical 

settlement/slippage of the end wall from the main building. A wide opening has formed 

between the front wall elevation and gable end 

xiv) It appears that the front wall is not ‘keyed’ into the end wall at gable end suggesting the wall 

to be a later construction (perhaps replacing an ‘original’ doorway opening into the main 

building during use as commercial premises). However, the front wall has a number of visible 

diagonal fractures, again indicating settlement/slippage of cutting slope material below. 

In addition to the localised defects highlighted above, it appears that a large percentage of the 

visible defects have arisen from foundations movement issues such differential settlement, 

foundation rotations and sliding, caused by soil creep or associate ground conditions discussed in 

detailed in Section 8. 

In view of the orientation and distribution of retaining walls fractures (e.g. East Side Boundary 

retaining wall) in conjunction with the actual wall geometry, we can draw the conclusion that the 

wall foundation slippage has produced large scale rotation of wall and extensive damage along 

the entire length of the structure. The sensitivity of the retaining wall footings to the underlying 

ground movement, may be a result of the wall construction details, such as inadequate sizing and 

depth of footings in relation to the actual ground conditions. However, this is subject to 

confirmation by record drawings or site investigations, as appropriate. 



8. Geotechnical Considerations 

Based on the local boreholes, the ground conditions are indicated to comprise London Clay below 

a thin layer of Made Ground which is consistent with site observations of the cutting slopes. 

The railway cutting and terrace forming the Highbury Roundhouse site area appear to have been 

constructed before 1895. Based on the local borehole evidence from the site, the terrace was 

formed by cutting only, ie it was not formed by cut and fill operations. Therefore London Clay can 

be anticipated to lie beneath the tarmac or concrete covered area. However, this should be 

confirmed by a site specific ground investigation. 

Movement of the retaining wall along the western side has occurred and the telegraph pole is 

leaning significantly. Longitudinal cracking of the tarmac/concrete surfacing was observed. 

However, signs of instability of the slope below this area were not seen. The historical maps show 

a building along the top of the cutting perpendicular to the Youth and Community Centre in the 

area. Therefore it is unclear whether the cracking and structure movements have been caused by 

movement of the slope or as a result of previous structural loading. As stated above, the wall only 

retains a low height of material which does not seem to be responsible for the significant wall 

movements. As the wall and telegraph pole are likely to have shallow foundations they may have 

been affected by swelling and shrinking of the highly plastic London Clay rather than slope 

movement. Although, if the foundations are very shallow they may have been affected by soil 

creep within the cutting. This wall has suffered extensive structural damage and requires removal. 

This wall could be replaced by another wall or a suitably founded fence in combination with some 

local regrading of the crest of the slope. 

The eastern retaining wall has undergone significant movement and requires either remediation or 

replacement as discussed in Section 7.4. 

The walls of a number of properties have had to be tied back as a result of structural movement 

probably resulting from swelling and shrinkage of the clay. 

There is a risk of contamination due to previous uses of the terraced area. However, no evidence 

of contamination was observed in front of the west side retaining wall at the top of the cutting and 

in addition no fly tipping or other piles of material were observed on the cutting slopes. It is 

recommended that an assessment is made of the likely contamination that may have been caused 

by the glass bottle works and latterly by the packing case factory. 

Any new construction on the terraced area would need to be founded sufficiently back from the 

top of the cutting so that the loading would not cause instability of the railway cutting. Slope 

stability analysis should be carried out to asses this risk using the results of a site specific ground 

investigation. However, typically any shallow pad foundations are likely to be required to be 

located 3m back from the top of a cutting. The type and size of the footings would be dependent 

on the loading of the structure. For a relatively lightweight 2 storey structure, pad foundations are 

likely to be acceptable founded at least 1m below ground level in the London Clay or deeper if 

trees or other mature vegetation is present. Based on the existing geotechnical data, the allowable 

bearing pressure for pad foundations in the London Clay is likely to be 100kPa for a settlement not 

exceeding 25mm. For more heavier structures, piled foundations are likely to be required. As the 

load is taken on the piles to deeper levels, piled foundations can be located closer to the top of the 

cutting. The piled foundations would typically be 15 to 20m in length depending on the loads that 

they would be required to carry. The area of any new building would also be constrained by the 

eastern retaining wall and the replacement of this wall using piles in front of the existing wall is 

recommended (see Section 10.3 and the sketch in Appendix F.2) as this would avoid disruption to 

the existing wall. 



9. Geotechnical Risks 

The main geotechnical risks are: 

• Instability of the west and east side retaining walls that would affect the scope or layout of 

any proposed development. 

• Presence of trees or other mature vegetation close to any proposed new development that 

would necessitate the structure to be founded on deeper pad foundations or piles taken 

below the zone of desiccation. 

• Presence of contamination below the tarmac/concrete area that would necessitate removal to 

a licensed tip and replacement with imported clean material. 

• Cracking of the walls of the Youth and Community Centre requiring stitching or underpinning 

if the building is to remain. 

• Presence of existing foundations from demolished buildings that would require removal prior 

to development of the site. 

• Instability of the railway cutting due to loading from any proposed development. 

• Unauthorised excavations into the side of the cutting which may cause slope instability. One 

embayment has been excavated into the cutting and it is recommended that no further 

excavations are permitted. 

• Effects of any additional loading on the tunnel should any proposed development extend into 

this area. 



10. Recommendations for Further Work 

10.1 Contamination 

It is recommended that a Phase 1 assessment is made of the likely contamination that may have 

been caused by the glass bottle works and latterly by the packing case factory. 

10.2 Ground Investigation 

It is recommended that a ground investigation is carried out within the tarmac/concrete area. This 

is primarily required to identify the cause of the longitudinal cracking and provide sufficient data for 

foundation design of any new structures. The ground investigation is likely to comprise the 

excavation of three trial pits within the cracked area of tarmac and adjacent area at the top of the 

railway cutting to investigate the cause of the movement. In addition three boreholes should be 

carried out across the site area where new buildings may be constructed. The depth of the 

boreholes would be dependent on the layout and loading any proposed structures and the type of 

foundations envisaged. It is recommended that the length of the boreholes should be at least 20m 

to allow the design of piled foundations if required. If the Phase 1 assessment identifies the 

possibility of the presence of significant contamination, the scope of the ground investigation 

should be extended to cover the required sampling and chemical testing. 

It is also recommended that a series of hand dug trial pits are excavated adjacent to the east side 

retaining wall to identify the founding depth of this existing wall. A series of horizontal trial cores 

should also be carried out through the (exposed) face of the retaining wall, to determine the wall 

geometry and the fill material beyond. 

The proposed ground investigation is likely to cost in the order of £15,000 to £20,000. 

10.3 Retaining Structures 

The discussion in section 7.3 has indicated the poor condition of the existing retaining walls and 

the Community Centre end wall, particularly in respect to horizontal and vertical fracturing, along 

with lateral movement. Whilst the majority of the retaining wall structures will require replacement, 

there are some sections of the East side Boundary Wall and Community Centre end wall, where 

local remedial works could be implemented. 

Stitch-and-Grout repair of the major fractures in the wall could be employed (using stainless steel 

bars criss-crossing the fractures in a random matrix) in an attempt to recreate monolithic action 

and a more robust structure. 

The remedial works offer a low-cost structural improvement, coupled with the installation of 3D 

measuring devices on the exposed wall faces either side of the fracture lines, with survey data 

collected at monthly intervals and a review of this data made after 12 months could be employed. 

On the other hand, there are a number of limitations or caveats which have to be noted, 

particularly as no historical monitoring of the East Side Boundary Retaining Wall is available to 

establish the trend in fracture propagation/enlargement or in geometric alignment (horizontally and 

vertically): 

• The essentially weak form of structure will be only partially relieved by re-establishing a 

degree of monolithic action in the wall. Re-emergence of fracturing is likely in due course 

• Structural integrity of the wall only partially addressed; in particular, the problem of rotational 

movement of the wall about its base and lateral displacement (if this is still occurring) 

Complete replacement of the retaining wall structures with a new piled wall, designed to 

accommodate the actual site conditions, is a long-term solution. 



The new wall, in the case of the East side Boundary Wall, could be erected in front of the existing, 

reducing any disruption to the owners of residential properties immediately behind the wall. 

Clearly, this is an expensive solution with a number of disadvantages, including: 

• Risk to existing structure stability during construction of new piled wall 

• Reduction in land area immediately in front of the existing wall 

In accordance with our comments presented in Section 7.4, we consider that in advance of 

applying local repairs to the East Side Boundary retaining wall, ground stabilisation would be 

required. In case of structure replacement with new retaining walls, we propose deep foundations 

using steel or concrete piles, which would be less sensitive to the surface ground movement. 



11. Summary 

The tasks carried out in connection with this geotechnical desk study have included a review of the 

existing geotechnical data, a topographical survey of the site, a condition survey of the existing 

retaining structures, a search of the underground services within the site boundaries and the 

preliminary scoping of an appropriate ground investigation. 

The findings of this study are summarised as follows: 

• The historical OS maps have shown that the existing site of the Youth Centre was occupied 

by a glass bottle works and afterwards by a packing case factory. Another building is also 

shown to have been present along the top of the railway cutting where ground movement has 

occurred. 

• The presence of contamination is not evident but it is recommended that a Phase 1 

contamination assessment is carried out to identify the potential effects of the past uses of 

the site. 

• Based on existing borehole data, the underlying geology is London Clay. 

• The walkover survey of the site did not identify any instability of the railway cutting itself. 

However, settlement and cracking in the tarmac along the top of the cutting has occurred, 

together with horizontal movement of the west side retaining wall, which requires further 

investigation. 

• Unauthorised excavations into the sides of the railway cutting have been carried out which 

may cause slope instability. It is recommended that no further excavations are permitted. 

• The condition survey has identified that the majority of the East Side Boundary Retaining 

Wall will require replacement, preferably with a new piled wall option (see Appendix F.2). 

However, an approx 12.5 linear metre length of the existing retaining wall, extending from the 

Community Centre building towards Ronalds Road, could be retained as part of the site 

development. 

• The existing West Side Retaining Wall should be removed and local regrading of the cutting 

slope carried out to a designed profile or it could be replaced with an alternative retaining 

structure. 

• Removal of the existing greenhouse structure near the toe of the railway cutting and the low 

level brickwork retaining wall and the cutting slope reinstated to its original profile. However, if 

structure is to remain in place, replacement of the retaining wall should be carried out with a 

new piled wall. 

• For a relatively lightweight 2 storey building, pad footings are likely to be acceptable on the 

terraced area founded at least 1m below ground level or deeper if trees or mature vegetation 

is present nearby. For heavier structures piled foundations are likely to be required. 

• Any new building on the terraced area would need to be located around 3m back from the top 

of the cutting if pad footings were to be used to avoid potential instability of the cutting slope. 

If piled foundations are to be adopted then the building footprint could be located closer to the 

top of the cutting. 

• From site observations and the responses received from Statutory Service Providers, details 

of a number of existing underground services within the site are still unknown. In the case of 

site drainage, the pipework is likely to be under private ownership and will need further 

investigation to determine exact location, route and connection with public mains system, in 

the absence of any plan details. 



It is proposed that the following works are carried out: 

• A Phase 1 contamination assessment to determine the potential contamination from previous 

land uses. 

• A ground investigation comprising three boreholes to a depth of around 20m in the area of 

the proposed development and around three machine dug trial pits to a depth of 3m along the 

area of cracked tarmac near the top of the cutting. 

• Investigation of the integrity of the section of the east side retaining wall that could potentially 

be retained, as well as the remainder of the existing wall. This proposed investigation should 

include a series of horizontal trial cores through the (exposed) face of the retaining wall to 

determine the wall geometry and fill material beyond, together with hand dug trial pits at the 

base of the wall to expose and confirm the depth of the wall footings. 

• Visual investigation of existing drainage routes within the site, to determine manhole 

locations, direction/discharge of flow.

Openreach Plant Maps Requested 

Dear Sir/Madam, 

NewSite Office (addresses can be located from the URL below) 

National Freephone: 0800 616 866 

Thank you for your request to: www.openreach.co.uk/networkinfo/ 

Enclosed are copies of our drawings marked up to show the approximate location of 

Openreach apparatus, which is present in the immediate vicinity of your works. It is 

intended for general guidance only. No guarantee is given of its accuracy. It should not 

be relied upon in the event of excavations or other works made near to Openreach 

apparatus, which may, exist at various depths and may deviate, from the marked route. 

To avoid damage it is recommended that mechanical excavators or borers are not used 

within 600mm of Openreach plant. Please ensure that our equipment is not enclosed, 

blocked, covered or otherwise obstructed by your plant. In the event of clearance not 

being adequate we anticipate that your plant is either resited, or an order is placed with 

Openreach for rearrangements of its plant. If there are any difficulties with the Map 

please ring 0800 616866. 

Please contact our Network Protection Service if required by dialling 0800 917 3993 or 

by Email on DBYD@openreach.co.uk giving seven days notice of your commencement 

date. This will provide you with on-site advice and a check of location for any 

Openreach apparatus. 

Further to this, I hope the following points will assist you at the new development: - 

Openreach has a licence obligation to provide service to any end customer requiring a 

connection. A Developer would not normally be charged for provision of service, our 

standard connection charges would apply to the end user when orders are placed with 

the communication provider of choice. However, should a Developer insist on an 

underground service in an area where Openreach plant is provided overhead, charges 

may be incurred. 

When the Developer has obtained contract and planning permission Openreach would 

request a ‘Clean’, scaled Site Layout, Location Map and a covering letter be sent to the 

relevant newSite Office. We would particularly request that you give details of your 

programmed site start date and likely first occupancy date where possible. To obtain 

contact details of the newSite office covering the development area click on the URL 

below. 

http://www.openreach.co.uk/networkinfo/developingournetwork/regionalcontacts.html 

Where a development affects existing Openreach apparatus in the public highway, the 

cost of any necessary protection or diversionary works must be borne by the Developer. 

In this case where a budget estimate is required a Site Plan, Location Map and a 

covering letter should be forwarded to the Repayments Project Office. To obtain contact 

details of the Repayments Office covering the development area click on the URL above 

and go to the Networks Protection and Alterations Page. 

Yours faithfully, 

Openreach newSites

E-mail: plantenquiries@instalcom.co.uk 

3. Where such details show that the works or the movement of plant or equipment may endanger the 

Apparatus of the Company the Contractor must give the Company Representative at least 7 days 

written notice of the date on which it is intended to commence such works of the movement of plant and 

equipment in order that the presence of any sub-surface apparatus can be indicated by markers to be 

supplied by the Company and placed by the Contractor under the supervision of a Company 

Representative. The Contractor shall ensure that all Company Apparatus, particularly surface running 

cabling is adequately protected from damage and such protective measures shall be approved by the 

Company Representative. 

4. In the event of a Company marker being disturbed for any reason, it shall not be replaced other than in 

the exact position of its former depth unless the repositioning is carried out at the direction and under 

The supervision of a Company Representative. 

5. The Contractor shall take particular care in relation to the protection of Company Apparatus, where such 

Apparatus includes the presence within the site of optical fibre cabling. 

The contractor should particularly note that the damage to such Apparatus is extremely disruptive 

to the Company network and costly to reinstate. The Contractor shall make every effort to avoid the 

disturbance of Company Apparatus more than is absolutely necessary for the completion of the works 

in accordance with the contract. 

CIV/005/02 1

6. When excavating around, moving or backfilling around Company Apparatus, the Company Representative 

shall be given adequate notice, which shall not be less than 3 days, of the contractors intentions in order 

that he may supervise the works. The Contractor should note that the normal depth of cover for Company 

Apparatus and ducts are as follows: - 

a. Carriageways 600mm 

b. Footways 350mm 

c. Verges 450mm 

These minimum depths of cover should be maintained wherever possible. 

Where the minimum depths of cover cannot be maintained, the Contractor shall carry out the instructions 

of the Company Representative for the protection of Company Apparatus. 

Where cables are not in duct and the required depth of cover cannot be maintained, such cables as are 

affected shall be enclosed and protected in UPVC duct or equivalent materials as supplied by the Company 

and by the method directed by the Company Representative. 

With regard to excavation in the vicinity of Company Apparatus the Contractor should have particular regard 

to the possibility of reduced cover and the encountering of such Company Apparatus at depths of cover less 

than that given at a, b and c above. 

7. All excavation adjacent to Company Apparatus is to be carried out by hand until the exact extent and/or 

location of Company Apparatus is known. Mechanical borers and/or excavators shall not be used within 

1.0m of Company Apparatus without the supervisory presence of a Company Representative, To prevent 

any movement of Company Apparatus during excavations, complete shuttering shall be used as directed by 

the Company Representative if:- 

a. Excavation is deeper than the depth of cover of adjacent Company Apparatus. 

b. Excavation is within 1.0m of Company Apparatus in stable ground. 

c. Excavation is within 5.0m of Company Apparatus in unstable ground. 

If for the completion of the works, the Contractor intends using any of the following: - 

a. Pile driving equipment within 10.0m of Company Apparatus. 

b. Explosives within 20.0m of Company Apparatus. 

c. Laser equipment within 10.0m of Company Apparatus. 

The Contractor shall advise the Company Representative, giving at least 7 working days written notice in 

order that any special protective measure for the Company Apparatus affected may be arranged. 

8. All Company manhole, joint box and /or other access points and chambers within the site shall be kept clear 

and unobstructed. Access for vehicles, winches, cable drums and/or further equipment required by the 

Company for the maintenance of it’s Apparatus, must be maintained at all reasonable times. 

The Contractor should particularly note that footway type jointing chambers are not specified for 

carriageway loadings and will need to be adequately protected and/or demolished and rebuilt under the 

supervision of a Company Representative where such chambers are likely to be placed at risk, either 

temporarily or permanently, from the movement of plant and/or equipment on the site. 

CIV/005/02 2

9. The covers to Company chambers and/or Apparatus shall only be lifted by means of appropriate keys 

obtained from the Company Representative and under the direct supervision of the Company 

Representative. No employee of the Contractor or of any sub-contractor employed by the Contractor shall 

enter any chamber and/or Apparatus of the Company unless under the supervision of the Company 

Representative and in any case not before the mandatory gas check has been carried out in the presence of 

the Company Representative and such checks have shown it to be safe to enter the chamber and/or 

Apparatus of the Company. 

The Company Representatives shall be given reasonable access to all Company Apparatus and chambers 

when required. 

10. In the event of any damage whatsoever to Company Apparatus, the Contractor shall immediately inform 

the Company Representative and report the occurrence immediately by contacting the Company as

With regards to your email below, Network Rail believes the scope of your proposed works has the 

potential to impact upon Network Rail. Therefore you should not proceed with these proposed works 

until you have contacted me with full details of your scheme at the earliest possible opportunity, so that 

safe methods of working with regards to railway operations and safety can be established. 

Please be aware that this response is based on Network Rail’s records (many of which have been 

inherited from predecessor Organisations) and knowledge and no guarantee can be given regarding 

accuracy or completeness. CAT scans, safe digging practices (as contained in HSE publications) and 

other appropriate investigative techniques should always be carried out. There may be other apparatus 

or buried services owned or operated by Utility Companies and accordingly you should contact 

individual utilities for information. 

If, in connection with your investigations and/or work, you become aware of Network Rail apparatus or 

buried services within your area of work, please ensure these are notified to me as a matter of urgency 

so that appropriate measures for avoidance of risk and damage can be put in place. 

Yours sincerely, 

Reston Mangezi

Dear Sir / Madam 

An Asset Location Search is recommended when undertaking a site development. It is 

essential to obtain information on the size and location of clean water and sewerage assets to 

safeguard against expensive damage and allow cost-effective service design. 

This search provides maps showing the position, size of Thames Water assets close to the 

proposed development and also manhole cover and invert levels, where available. 

Please note that none of the charges made for this report relate to the provision of Ordnance 

Survey mapping information. The replies contained in this letter are given following inspection 

of the public service records available to this company. No responsibility can be accepted for 

any error or omission in the replies. 

You should be aware that the information contained on these plans is current only on the day 

that the plans are issued. The plans should only be used for the duration of the work that is 

being carried out at the present time. Under no circumstances should this data be copied or 

transmitted to parties other than those for whom the current work is being carried out. 

Thames Water do update these service plans on a regular basis and failure to observe the 

above conditions could lead to damage arising to new or diverted services at a later date. 

Contact Us 

If you have any further queries regarding this enquiry please feel free to contact a 

member of the team on 0118 925 1504, or use the address below:

Waste Water Services 

Please provide a copy extract from the public sewer map. 

Enclosed is a map showing the approximate lines of our sewers. Our plans 

do not show sewer connections from individual properties or any sewers 

not owned by Thames Water unless specifically annotated otherwise. 

Records such as "private" pipework are in some cases available from the 

Building Control Department of the relevant Local Authority. 

Where the Local Authority does not hold such plans it might be advisable to 

consult the property deeds for the site or contact neighbouring landowners. 

This report relates only to sewerage apparatus of Thames Water Utilities 

Ltd, it does not disclose details of cables and or communications equipment 

that may be running through or around such apparatus. 

The sewer level information contained in this response represents all of the 

level data available in our existing records. Should you require any further 

Information, please refer to the relevant section within the 'Further 

Contacts' page found later in this document. 

For your guidance: 

• The Company is not generally responsible for rivers, watercourses, 

ponds, culverts or highway drains. If any of these are shown on the 

copy extract they are shown for information only. 

• Sewers indicated on the extract of the public sewer map as being 

subject to an agreement under Section 104 of the Water Industry Act 

1991 are not an ‘as constructed’ record. It is recommended that these 

details are checked with the developer. 

Clean Water Services 

Please provide a copy extract from the public water main map. 

Enclosed is a map showing the approximate positions of our water mains 

and associated apparatus. Please note that records are not kept of the 

positions of individual domestic supplies.

outside stop valve. If you would like to know the static pressure, please 

contact our Customer Centre on 0845 920 0800. The Customer Centre can 

also arrange for a full flow and pressure test to be carried out for a fee.

Notes: 

1) All levels associated with the plans are to Ordnance Datum Newlyn. 

2) All measurements on the plans are metric. 

3) Arrows (on gravity fed sewers) or flecks (on rising mains) indicate direction of flow. 

4) For symbols referred to as ‘Other’ on this key, please see the plan for further 

information. 

5) Most private pipes are not shown on our plans, as in the past, this information has 

not been recorded. 

6) -9999.00 or 0 on a manhole level indicates that data is unavailable. 

7) The text appearing alongside a sewer line indicatesthe internal diameter of the 

pipe in milimetres. Text next to a manhole indicates the manhole reference 

number and should not be taken as a measurement. When cover and invert 

levels appear on a plan they are clearly prefixed by ‘CL’ and ‘I L’. I f you are 

unsure about any text or symbology present on the plan, please contact a 

member of Property I nsight on 0118 925 1504.
