Manual of Engineering Standards and Specifications
The Manual of Engineering Standards and Specifications (MoESS) is 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 that 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 is also the base of the contract documents used for City capital works projects.
More information can be found in the Introduction section of the MoESS.
The current edition, MoESS Edition No.14, was adopted on July 4, 2022 by City Council. It can be viewed and downloaded in PDF format below. A copy of the MoESS can be requested and picked up at the Service and Resource Centre, 411 Dunsmuir Street by emailing engineeringinfo@nanaimo.ca or calling 250-754-4251 ext. 4230 at a cost of $50 plus GST.
