City of Surrey Construction Drawing Standards Specifications, Nov 2005
1. Drawing Standard Specification: Introduction
The City of Surrey receives over 2000 Final Design or As-Built Construction Drawings
(hereinafter referred to simply as “drawings”) per year from outside developers and consultants.
Each of these drawings are recorded, scanned, organized and stored within the City’s network, as
well as digitized into the City’s GIS System.
The process is labour intensive, and can often be quite time consuming. A key strategy often
employed by municipalities to counter this is to define, implement, and enforce drawing
standards. Intuitively, it makes sense that the more standard drawings are, the more efficient
processing the drawings can become.
This document fully specifies the standards each drawing submitted to the City must adhere.
Not only will adherence to these standards guarantee that drawings will not be rejected, but will
also help to ensure a quick turn around, enabling developers to obtain project acceptance sooner.
These specifications are not new. They have been refined to detail specifications applicable to
both hard-copy and digital formats, both of which are required at the time of submission.

City of Surrey Construction Drawing Standards Specifications, Nov 2005
2. Drawing Submission Process
Drawings must be submitted to the City three times over the course of a typical land
development project: at the Final Design (Early Copy) stage, the Preliminary As-Built
Submission stage, and the Final As-Built submission stage. Only after drawings for each stage
are submitted, processed, and accepted will the project obtain a Certificate of Acceptance.
Each submission package must contain a set of hard copy drawings, and one digital file, which
must include all service features. The set of hard copy drawings must include a Key Plan
Drawing, and a separate drawing for each applicable service type (see Table 1) 1 . Please see
Section 3 for a detailed description of all the hard copy drawing standards. The digital file must
either be in either Autocad or Microstation format. Please see Section 4 for a detailed
description of the standards the digital data must adhere to.

Notes:
1. Drawings with incomplete, non-standard or confusing information will be returned for
correction and/or clarification.
2. All drawings submitted remain the property of the City.
2.1. Final Design (Early Copy) Submission
The first time drawings are submitted to the City is at the Final Design Stage, also referred to by
City staff as the Early Copy stage. Two sets of hardcopy drawings and one digital file are
required. These drawings are forwarded to the City’s GIS Section for input into the GIS
database. Typically, these drawings are rough copies used to indicate proposed infrastructure
development.
1 Also refer to The City of Surrey’s Design Criteria Manual for a more detailed description of services required.
Page 2

City of Surrey Construction Drawing Standards Specifications, Nov 2005
Ideally, these drawings would adhere to all standards detailed in Sections 3 and 4, however they
are not strictly enforced at this stage.
2.2. Preliminary As-Built Submission
Once construction is complete, two hardcopies of each As-Built drawing, and the associated
digital file must be sent to the City. Upon receipt, the City forwards the drawings to the GIS
Section for input into the GIS database. The GIS Section records the receipt of the drawings,
assigns Surrey Drawing Numbers, reviews the drawings for completeness of design and
adherence to standards, and inputs all new services into the GIS.
Any deviation from standards, omissions, or any other deficiencies to the drawings are noted.
All drawings are returned to the consultant for final review and updates. The City expects any
deficiencies are corrected, and that the Surrey Drawing Numbers are entered on each drawing.
Once complete, the drawings can be sent back to the City for final acceptance.
Please note that the most frequent deficiency encountered involve the placement of features and
the dimensions and offset distances associated with those features. Placement of features must
be geographically correct. Any dimensions or offset distances displayed must be to scale (e.g. If
the offset distance of a manhole from a lot corner is listed as 2.1m, the placement of the manhole
must be 2.1m from the lot corner). Simply changing the offset distance without moving the
service feature accordingly is NOT acceptable.
2.3. Final As-Built Submission:
Final Submission must include:
• The original marked-up set of paper prints
• Two sets of corrected paper prints, (One set must be sealed).
• One digital file that includes all new services. See section 4 for details on digital copy
standards.
The Final Submission is reviewed to ensure all corrections have been made appropriately. If so,
the drawings are scanned and stored on the City’s network for posterity. A final acceptance
letter is produced and sent to the consultant along with the release of any funds held back
pending final acceptance. If drawings still have deficiencies, they are again returned to the
consultant for corrections.

3. Hard-Copy Drawing Standards
This section fully details standards that apply to any hard copy drawing submitted. Each
drawing must adhere to the general page layout and drawing standards described in Sections 3.1
and 3.2. Individual service drawings each have specific standards associated with them. See
Sections 3.3 through 3.10
3.1. Page Layout
All hardcopy drawings must be printed on a standard A1 size page, and must include a plan view
and a profile view. In addition, the drawings must include a profile grid, a Title Block and a
Revision Block.

The project will not be accepted unless a set of sealed paper prints is submitted. Each original
drawing must include the following text:
Page 4

City of Surrey Construction Drawing Standards Specifications, Nov 2005
“A set of sealed paper prints has been submitted with this
original by____________________, the Engineer of Record”
3.1.1. Plan View
1. The plan view is to be drawn at a scale of 1:500. The profile to be drawn to scales
horizontal 1:500, vertical 1:50. A horizontal scale of 1:250 is also acceptable only where
the project is small enough to fit on a single sheet at 1:250. A vertical scale of 1:100 is
acceptable in extreme cases.
2. All offsets of services, existing and new, will be indicated to the nearest 0.1m and
referenced to and along property lines. Offsets for new mains are to be circled.
3. Benchmarks (including TBM’s) are to be noted in the legend with location and elevation.
Survey monuments are to be shown on the plan view.
4. The plan view will show the legal layout of roads and properties with all legal
descriptions (lots and plan numbers) and dimensions (to the nearest 0.01m). Also show
existing house numbers and all registered statutory rights-of-way.
5. The names of streets are to be indicated outside of the road boundaries. Road widths are
to be annotated. No temporary (e.g., A, B or C) names will be accepted.
6. All work done must be shown (e.g. removal of a clean out or replacement of a clean out
by a manhole, removal or existing blowdowns, lines abandoned, etc.) and clearly noted
on the appropriate drawing.
7. An offset from lot corners must be shown for all service connections. (The note
“centreline of lot” or “typical” is not acceptable.) If the connection is not perpendicular
to the main, the location of each bend is to be shown.
8. The rim, invert and depth (where applicable) are to be shown for all service connections
and are to be “boxed” in.
Where there are existing connections, the field-measured inverts are to be shown. Where
information has been obtained from an as-built drawing this must be clearly noted.
9. Two dimensions from lot corners are required to show the location for all manholes,
valves, tees, hydrants, stubs, catchbasins, lawnbasins, bends in water lines, etc.
Note: the “Location” of manholes as shown on the drawings are to be the location of the
intersection of the pipes within the manhole, not the centre of the lid. When there is a
major difference, a note stating the offset of the manhole lid should be added to the
drawing.
10. Where chainage is used to locate services, bends, etc., the baseline must be shown and
dimensioned to the legal along with all curve data. Each change of direction (pipe
deflections) must be noted and tied with dimensions to lot corners; or noted as follows:
• pipe pulled from sta. ____ to sta. ____
• BC at sta. ____
• EC at sta. ____
Page 5

City of Surrey Construction Drawing Standards Specifications, Nov 2005
• bend at sta. ____
Stationing is to be clearly noted if either baseline or centreline of main chainage is used.
11. New works are to be drafted in bold lines and the offset of these works are to be circled.
12. On curves clearly locate all fittings to the baseline and/or lot corners.
13. All notes and dimensions are to be placed outside of the road right-of-way.
3.1.2. Profile View
1. The profile view must show:
• chainages and profile along the baseline
• elevations of new and existing works
• new and existing service connections
• services being crossed by the new works (and their elevations)
• all data pertaining to the design of the works
2. Elevations at all grade changes are to be shown with a chainage or ties to lot corners.
3. All elevations are to be geodetic and rounded to the nearest 0.01m.
4. Starting chainages on profile views must coincide with an accented vertical line on the grid
and must line up vertically with the station on the plan view
5. The material type (PVC, concrete, etc.) must be shown on the profile for all mains.
6. Rim elevations are required for all manholes and clean outs.
7. All manhole and clean-out sizes are to be noted. If standard 1050 mm diameter is used, a
general note is acceptable with any non-standard sizes clearly noted on the profile.
8. Profiles must be shown for all services (including road crossings) except where the
installation of connections from an existing main is the only work performed.
9. Pipe measurements should be from the centre of each associated manhole. Chainage
distances are not acceptable.
10. For drop manholes, note whether ‘inside’, ‘outside’ or ‘ramp’ manhole.
11. Where a new main breaks into an existing main, show the location and inverts of both
existing upstream and downstream manholes relative to the new works.
12. Note all additional requirements pertaining to specific service drawings. See Section 3.1.
3.2. General Hardcopy Drawing Standards
The following standards apply to all submitted Early Copy and As-Built drawings:
1. A separate drawing is required for each service type (see Table 1).
2. Key plans are to show ‘as-built’ information for those services not shown on other
drawings within the project.
Page 6

City of Surrey Construction Drawing Standards Specifications, Nov 2005
3. Notes pertaining to the construction of a particular service type are to be shown on the
applicable service drawings, not on the Key Plan.
4. All dimensions and elevations are to be in metres.
5. All drawings must include existing infrastructure within the project area. Each of the
following, if applicable, must be illustrated:

10. Drawing must be printed using the maximum line density
3.2.1. Spatial Positioning of Services on Hard-Copy Drawings
All service features (mains, manholes, connections, etc.) must be placed at their correct spatial
location. Proposed and existing features (if impacted by the project) must be placed at their
proper locations in the drawing. It is not acceptable to simply change the value of the
associated dimension string.
3.2.2. Baselines
General Baseline requirements:
1. Offsets are to be shown to both sides of the road allowance or to one side with the road
allowance width annotated.
2. Baseline change of direction (bend, curve, deflection, BC, EC, etc.) must be noted.
3. Each drawing must have sufficient baseline information to stand on its own.
4. If features are within an ISA, then all baselines are to be referenced to two Integrated
Survey Monuments.
5. If features are outside ISA, then all baselines are to be referenced to two property corners
(stationing for all IP’s found) and shown on the drawings.
3.2.3. Chainages
1. Chainage stations must be at 20 metre intervals (+20, +40, etc.) and rounded off to the
nearest 0.1m.
2. Chainage intersections and starting points are to be related to lot corners (1 + 00).
