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 2017 updated 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:

.6 Vacuum up all dust and debris.

3.5 INSTALLATION OF INSULATION ON ORIGINAL VAPOUR BARRIER .1 Install insulation over existing vapour barrier using two part low rise

foam in beads spaced at 6” c/c over the entire area of cleaned off vapour barrier. Bead to be minimum of 1/2” diameter when it exits the nozzle.

.2 Cut end pieces to fit tightly.

.3 Ballast down each 4’ x 4’ piece of insulation with four rolls of membrane standing on end until adhesive has achieved lock up.

3.6 INSTALLATION OF INSULATION COVER BOARD

.1 Install an 8” width of base sheet around the perimeter of the new insulation area as per the detail to provided a barrier to flame getting to the edges of the existing roof which has a double ½” fiberboard insulation cover board.

.3 Heat weld all end and side laps.



3.7 PREPARATION OF EXISTING CAP SHEET TO RECEIVE NEW CAP SHEET .1 Cut out all blisters in existing cap sheet and apply torched cap sheet

patches set flush to edges of existing membrane.

.3 Heavily prime the prepared surface of the existing cap sheet and let it dry completely.

3.8 EXPOSED MEMBRANE APPLICATION

.1 Cap sheet application: .1 Starting at low point on roof, perpendicular to slope, unroll cap

sheet, align and re-roll from both ends. .2 Unroll and torch cap sheet onto base sheet taking care not to

burn membrane or its reinforcement. .3 Lap sheets 75 mm minimum for side laps and 150 mm

minimum for end laps. Offset joints in cap sheet 300 mm minimum from those in base sheet.

.4 Application to be free of blisters, fishmouths and wrinkles.

.5 Do membrane application in accordance with manufacturer's recommendations.

.2 Self-adhesive membrane flashing application: .1 Prime the exterior wood surface of the roof edge blocking and

install self-adhesive membrane over the full surface. Lap modified bituminous flashing membrane down over the self-adhesive membrane without torching and nail with roofing nails at 6" c/c along the edge of the membrane.

3.9 SEAL AT DUCT SUPPORT POSTS INSTALLATION .1 Install the ChemCurb / Soprema System as per the printed instructions

of the manufacturer.

.2 Remove all previous caulk, mastic cement, asphalt and other contaminants from the surface of the posts with a wire brush to ensure proper bonding.

.3 Ensure that there is a minimum of 1" spacing between the post and the edge of the shell.

3.10 METAL FLASHING .1 Generally existing to remain.



3.11 CLEANING .1 Remove bituminous markings from finished surfaces.

.2 In areas where finished surfaces are soiled by work of this section. Consult manufacturer of surfaces for cleaning advice and comply with their documented instructions.
