Engineering Record Drawings - Drafting Standards and Submission Requirements

Application

The City of London's Engineering Record Drawing - Drafting Standards and Submission Requirements manual applies to all engineering works that are or will be owned by the City or that will be privately owned but lie on City property. Examples include public works projects done under contract with City as well as public works resulting from developments including Subdivisions, Condominiums, site plans and servicing agreements. Engineering Consultants are required to submit Engineering Record Drawings in accordance with this standard to the Geomatics Division, Room L106 at City Hall.

Note these standards do not apply to draft plans, legal surveys, topographic surveys, architectural and engineering drawings associated with facilities such as treatment plants, pump stations, bridges, some of which are discussed below.

Submission Milestones

Engineering plans are required to be submitted at two milestones of a project:

The approved construction drawings are required immediately upon final acceptance of the drawings in which case the submission will include a complete set of full sized paper prints signed and stamped by the Project Engineer, together with the associated digital files.
The post construction Engineering Record Drawings including signed and stamped mylar originals and their associated digital files are required upon final acceptance by the Geomatics Division.

Version

Note: Drawing standards may be updated at any time.

Digital Plan Submissions (General)

The following digital plan submission requirements apply to draft plans, site plans, legal survey plans and topographic survey plans completed either on behalf of the City or for a private party where the plan will be the subject of review and approval by the City.

General Requirements

Draft plans of subdivisions and site plans submitted to the City of London's Planning Department for approval at any stage shall be submitted along with a digital version of the plan in AutoCAD DWG digital format. In general, there are no restrictions as to the content and format of the graphic data, including layering and symbology, with the exception of the construction layer.

Construction Layer

All plans must contain a construction layer named "LINEWORK" that incorporates all relevant linework including the boundary of existing limits, new parts, proposed streets, lots, blocks, street widenings and reserves which represent the proposed development. Underlying lot fabric or linework lying outside the subject development shall not be included on the construction layer, nor shall the construction layer contain any other extraneous information including text. The linework contained on the construction layer must be in its precise real-world location and not exaggerated for the purpose of cartographic clarity. The construction linework must not be unduly broken (e.g., by iron bar symbols or text) and a reasonable effort must be expended to ensure that the linework is polygon ready (i.e., ends of lines and arcs join precisely where intended and crossing lines are broken). The construction layer line style shall be continuous (solid) but can be any colour and weight.

UTM Referencing

Digital files must be referenced to the City of London's geographic reference system which is the NAD'83 datum, 6 degree UTM projection expressed in meters. The digital file must be submitted scaled to grid (i.e. the UTM projection). All dimensions shall be shown as ground level distances. For most projects in the City, a combined scale factor of 0.9995650000 can be used to convert from ground-to-grid.

Supplementary Information

The digital file should contain sufficient information to assist City staff in evaluating the application. Helpful information will likely include street names, lot numbers, abutting linework, key map and map surround with title block, plan number, date, etc. All such additional information can be submitted on any layer using any symbology but it is strongly suggested that standard fonts be used so that any plots generated by City staff for internal use are similar to the hardcopy submission. For expediency, contours and DTM data should not be included with the file.

Digital submissions

The files are to be submitted in AutoCAD DWG (2D) format and must be able to be read using the latest version of AutoCAD without the need for special add-on software that may have been used to generate the drawing. The construction layer containing the linework described above shall be named "LINEWORK" and must not be blocked. The digital file must be submitted in model space with tile mode set to one and must have no references to paper space and no reference files are to be used. The file units must be in metres georeferenced to the City's horizontal control system (NAD'83 datum, 6 degree UTM projection) with the User Coordinate System set to World and be in an unrotated plan view at 1:1 scale. City staff will not attempt to transform drawings to the City's horizontal control system therefore it is strongly suggested the applicant first check the drawing by referencing it to the City's Parcel Mapping/Topographic mapping from the City's Mapping CD.

Legal survey Plans

The following standards apply to the preparation of legal survey plans by Ontario Land Surveyors, either on behalf of the City of London or for a private party where the plan will be the subject of review and approval by the City.

All legal surveys done in the City of London must be georeferenced to the City's NAD'83, UTM Zone 17 horizontal control network. Survey plans will use the requisite UTM grid bearing reference and show UTM coordinates for at least two boundary points on the face of the plan. The above digital plan submission requirements apply to legal survey plans. The City reserves the right to request a digital copy of the plan, but unless specifically requested a digital copy does not have to be submitted.

Metric Units

Unless otherwise authorized, all plans shall be drawn in metric units.

UTM Control Reference

Unless otherwise authorized, all surveys completed for the City shall be referenced to the City's georeferencing system (currently the NAD83 datum, UTM projection) using only City approved control. Plans shall use grid bearings and adjusted ground level distances. Each plan shall show UTM coordinates for at least two boundary points (more if the plan is very large).

Form 2 - Include Areas and Transferee

In addition to the mandatory Form 2 schedule under O.Reg. 43-96, the area and transferee shall be listed for each Part. Areas shall be expressed in both acres (to three decimal places) and hectares (to 4 decimal places) or to the nearest square metre.

Preliminary Plan Submission Requirements

When submitting the plan to the office of the Chief Surveyor (Geomatics) for approval, the following is required:

PDF image of the preliminary plan.
Hardcopy of the title search including block map, PIN sheet of the subject property, copies of deeds and transfers, easements and plans. This package will not be returned to the consultant.

Final Plan Submission Requirements

The final submission to the office of the Chief Surveyor (Geomatics) shall include the following:

PDF image of the final plan.
DWG file.

Fair Use of Plan

The City retains the right to use, modify and/or distribute DWG file to third parties as it deems necessary, but in so doing all references to the original surveyor shall be removed.
