Manual of Engineering Standards and Specifications

The Manual of Engineering Standards and Specifications (MoESS) forms part of the Subdivision Bylaw and is referenced in several other City bylaws. It is a guide for the construction of City-owned civil engineering projects.

The MoESS is used by anyone designing or constructing work within existing or future City rights-of-way. This includes streets within subdivisions which are to be turned over to the City, works and services fronting building developments, and capital works projects undertaken by the City itself. The MoESS also forms the basis of the contract documents used for City capital works projects.

Further detail can be found in the Introduction section of the MoESS.
