PART 1: GENERAL 1.1 DESCRIPTION OF THE WORK

.1 The intent of the work is to remove and replace the asphalt traffic topping and waterproofing system at the East Parkade roof deck and repair the concrete roof deck with allowances for localized concrete and waterproofing repairs at the ‘East’ and ‘West’ Parkades in downtown Guelph (off Macdonnell Street).

The Owner reserves the right to limit the extent of the Work actually carried out to any part of that described below. All work must be carried out in accordance with the attached specifications, Building Code requirements, and manufacturer’s recommendations as directed by the Engineer.

West Parkade (Predominantly Pre-Cast Concrete):

i. Provide any and all access equipment, hoarding, shoring, and bracing necessary to both safely complete and inspect the work.

ii. Supply and install heavy duty elastomeric waterproofing system on the

cast-in-place concrete ramp assembly at the P2 level, including fully encapsulating all related curb assemblies and onto surrounding slab surfaces by a minimum of 400mm. (It may be assumed that all traffic will be diverted around this ramp for the duration, provided the installation is completed without undue delay in the sole discretion of the Engineer).

Identify all delaminated concrete within designated work areas and repair as specified where authorized by the Engineer and in accordance with suitable Unit Rates using prepackaged repair material (FA-S10 by King Packaged Materials Company or approved equal).


Re-apply affected traffic markings and curb-paint to match existing.

East Parkade (Cast-In-Place Concrete):

iii. Provide any and all access equipment, hoarding, shoring, and bracing necessary to both safely complete and inspect the work.

iv. Remove the existing asphalt traffic topping and related waterproofing at

the East Parkade roof slab and dispose of off site. Identify all delaminated concrete within designated work areas and repair as specified where authorized by the Engineer and in accordance with suitable Unit Rates. Supply and install new 2 ply fully reinforced hot-applied rubberized asphalt waterproofing system and butt-jointed asphalt protection boards (including related “upturns” and “downturns”), “bonded” asphalt surfacing (2 min. 40mm layers and sloped to drains). Reinstate traffic markings to match existing layout.

v. Remove and replace mastic asphalt traffic topping and waterproofing

system at intermediate suspended slab locations authorized by the Engineer. It can be assumed that waterproofing and topping repairs will be confined to one area of the parking garage and will not be scattered throughout. Identify all delaminated concrete within designated work areas and repair as specified where authorized by the Engineer and in accordance with suitable Unit Rates.

vi. Remove and replace existing ‘catch-basin’ drain assemblies with new

assembly PROVIDED BY THE OWNER (or reuse existing assemblies if deemed appropriate) as specified below.


If authorized, remove and replace existing drain assemblies in conjunction with surrounding waterproofing replacements. Re-locate or supply and install new 4” epoxy coated drains with hinged grates and sediment bucket assemblies as specified and directed. Carry concrete repairs not associated with drain replacements in Unit Rates.

vii. At top deck level, supply and install dowelled-in 4” by 4” concrete curb assembly along edge of slab along length of slab and waterproof in conjunction with other waterproofing as necessary to avoid water running over the slab edge, including ‘tying into’ existing curb.

Elevated Walkway (Optional):

viii. Provide any and all access equipment, hoarding, shoring, and bracing necessary to both safely complete and inspect the work.

ix. Identify all delaminated concrete on the elevated

walkway and repair as specified where authorized by the Engineer.
