| STRONG | On track for Rail Acton Town to Chiswick Park Embankment Stabilisation This recently completed scheme for LUL, with a value of c £2.5m, required a number of solutions at 5 separate locations between two stations on the District Line. The first 3 locations were undertaken during two weekend track possessions utilising road/rail plant to install 161 5 metre driven steel piles infilled with 1100 concrete planks, the void between the track and the new structure was raised with 250 tonnes of compacted gravel wrapped in a geo textile membrane; a new trackside walkway and safety handrail completed the works. The next two locations were undertaken during traffic hours as access, whilst restricted, was possible from the highway, a partial road closure allowed scaffold access to the failing embankments, which were in a confined area between the track and local residences. A reduced dig operation was undertaken at both locations, each of which were accessed from a single entry point, removing 1250 tonnes of spoil and installing temporary works to support the adjacent track prior to reconstruction of the embankments. The LUL design had specified the raising of the existing lower retaining wall by 1.7m and a revised profile created using a new proprietary system Ram Wall. This comprises of a galvanised steel grid installed and fixed in sections to an agreed pattern to give structural strength, infilled with a lightweight Maxit aggregate which reduced the loadings on the higher embankment compared to traditional fill materials. Over 1400m 3 of Ram Wall and 1900m 3 of Maxit were installed over the 280m length of the two sites, making it the largest scheme built using the system. The structures were capped with 150mm of seeded topsoil, with a new walkway and safety handrail installed. During the construction of these works Clancy Docwra tendered for, and has been awarded, a 5 year framework for earthworks and embankment stabilisation with LUL. Gants Hill Ventilation Shafts VP50 &VP50a One of many ventilation shafts on the LUL Central Line, Shafts VP50 and VP50a surface at a roundabout on the busy A12 trunk road. Both brick built structures had been identified as having defective steelwork supporting the safety grills protecting the opening. Scaffolding was erected under TfL traffic management incorporating a birdcage deck enabling access to the defective steel and to protect the track below. Safety grills to VP50a were removed and all supporting steelwork to the 5metre diameter shaft was prepared and repainted using a three coat system, prior to the reinstalling and securing the grills Shaft VP50 was a smaller rectangular shaft over a machine room not the track, but requiring equal protection and a different solution. The lighter steel work supporting the safety grill had deteriorated to the point where replacement was required; following the strip out of the old structure new galvanised steelwork was manufactured and installed to include new safety grills. Project Manager Mark Driscoll confirmed that the project with a value of £28k, which was secured as part of £1.6m package awarded under the LUL Civils Lot B Framework, has progressed well and to the satisfaction of both LUL and Tfl. 14 | <strong>Autumn</strong> Issue
Rail in the North R ail activity in the North of England and Scotland has experienced a welcome boost from contract wins with Strathclyde Passenger Transport (SPT) and Network Rail. The Glasgow Subway operated by SPT has been allocated significant funding for the upgrade of stations and rolling stock. The Livingston office has won, and is on-site delivering the refurbishment of the first of the stations at Hillhead in Glasgow. The station serves the busy and fashionable West End of Glasgow and Glasgow University making it one of the busiest on the system. The Clancy Docwra team is working constant night shifts to carry out a full refurbishment including ceiling, wall and floor finishes, electrical installation, relocation of ticket offices and retail units, escalators and new external security and finishes. The stations have not been refurbished for several decades and this, coupled with tight working conditions and the need to hand the station back each morning fit for operation adds to the complexity of the project. The bid value was £1.2 million and successful performance could pave the way for further awards as the station programme continues over the next few years. Steve Meikle, Operations Manager said “the project is really picking up momentum now and we are working closely with the client and other team members. We look forward to the possibility of putting all we have learned into practice on future jobs”. In addition to winning a contract with Network Rail to upgrade a series of relay rooms in Central Scotland (£150k) the Rail team has had a | STRONG | major breakthrough in winning the Geneva Junction (£800k) and LNE Culverts contracts (£200k). Geneva Junction is an embankment stabilisation job whilst the culverts will have a work scope refurbishing and replacing culverts in locations at Carlisle, Selby and Sheffield. Regional Manager Paul Eadington said “we are delighted with these breakthrough wins and are focussed on delivering well for the client with the prospect of some follow-on work”. TPS Lot 3B General Building Framework Awarded in 2010 this 5 year framework agreement covers general building works at stations and depots for SSL and BCV who are responsible for two thirds of the LUL network. Projects are competitively bid by four contractors with a very high volume of schemes ranging from reactive maintenance to medium sized projects, all requiring a fast turnaround for pricing and delivery. Project Managers Kevin Barrett and James Carty take a proactive hands on role in all aspects of the framework, with their dedicated commercial and site teams now delivering around £1.0m of contracts annually. See At Work With on back page. It is with sadness we report the sudden death of Derek O’Sullivan aged 29, the eldest son of Rail Project Manager Dermot O’Sullivan. Our sympathies are extended to Dermot and his wife Jenny, Derek’s brother Gary and his sisters Aóife and Emér. <strong>Autumn</strong> Issue | 15
