OVERVIEW
This document is a Supplementary Specification to the Standard Specification for Municipal
Services, developed by the Nova Scotia Roadbuilders - Consulting Engineers of Nova Scotia
Joint Committee on Contract Documents.
The Halifax Regional Water Commission (“Halifax Water), in response to a need to standardize
their specification practices, reduce review and approval time, and regulate the specifications
produced by their consultants, have adopted the Standard Specification for Municipal Services.
As an active member on the Joint Committee during the Standard Specification’s development,
Halifax Water became familiar with, and contributed input to, the Standard Specification’s
development.
Whereas the Standard Specification is intended for both sewer and water projects throughout the
province of Nova Scotia, Halifax Water’s concern is limited to water and wastewater systems
within the limits of the Halifax Regional Municipality, additional specification requirements will
be provided as supplementary specifications.
These project documents have been prepared for use with and require being read in conjunction
with the latest updated 2017 version of The Standard Specifications for Municipal Services as
published by the Nova Scotia Roadbuilders – Consulting Engineers of Nova Scotia Joint
Committee on Contract Documents. Copies of The Standard Specification for Municipal
Services are available from the Joint Committee on Contract Documents, 18 Laurier Street,
Dartmouth, Nova Scotia, B3A 2G7; Telephone (902) 233-9362, OR Email:

"Revise & Resubmit" - Make the necessary revisions and resubmit revised
drawings for review. Show the drawing number of the first such revised
drawing and show the latest revision number applicable to the drawing by
adding a suffix to the drawing number as - "Rev. 1", "Rev. 2", etc.
.3
"Not reviewed" - This notation indicates when the Engineer has not reviewed
the drawing. It may also be used in combination with the notation to revise and
resubmit the drawing where the Engineer lacks sufficient information to
complete the review and requires resubmitting the drawing for review after
revision.
.4
Drawings will be marked "Reviewed" together with the notation to "Revise &
Resubmit" when the Engineer requires a resubmission of a revised drawing
showing corrections made as a result of the Engineer's notations on the shop
drawings. This procedure will not relieve the responsibility for errors or
omissions in the shop drawings or of responsibility for meeting all requirements
of Contract.
Use only those shop drawings on the work that bear the "Reviewed" notation.

Neither the General Contractor, Engineer, nor the Owner will accept responsibility
for the cost of changes necessary if any equipment is fabricated without prior review
of shop drawings. Completion of the Engineer’s review will be designated by the
presence of his/her initialed reviewed stamp on the returned drawings.
.19
Where more than one type of shop drawing has been specified for one item, e.g.,
wiring diagrams, layout details, and dimensional drawings, the shop drawings will be
submitted together, to enable the Engineer to review the drawings as a package.
.20
Catalogue pages or drawings applicable to an entire family or range of equipment will
not be accepted as shop drawings unless they are clearly marked to show the pertinent
data for the particular materials.
.21
Manufacturers' catalogues, manuals, or price lists will not be accepted as shop
drawings. Such materials may be used as supplemental information to the shop
drawings.
.22
Determine which shop drawings have, in addition to those drawings specifically
mentioned in the Contract, design elements requiring the seal of a Professional
Engineer registered in the Province of Nova Scotia, in accordance with the applicable
provincial or federal engineering acts or other governing legislation. Seal such
drawings before submitting them for review. Submit for review engineering
calculations signed by the registered Professional Engineer responsible for the shop
drawing design elements.
