Bayside Engineering, Inc. was awarded three consecutive design contracts for this work with the City of Boston Public Facilities Department for renovations to Boston City Hall. The scope of work began with a comprehensive and in-depth study of the building envelope.  Following is a short description of the 3 phases of work included in this project. Phase I: This phase included replacement of selected roof areas and repairs to parapets. The repairs to the parapets included removing existing caulking and installing new caulking with backer rods.  Repairs were also made to spall areas of the precast concrete parapets and copings.  Bayside provided design and construction administration and construction inspection services.

Phase II: This design contract addressed two specific items: Replacement of all remaining roof areas and waterproofing repairs to the concrete terraces on the eighth and ninth floors. Since the work required two different specialties, the project was split and bid as two construction contracts.  The work to repair the ponding and leaking terraces required removing the concrete surface slab as well as removing the insulation and waterproofing system down to the clean concrete.  A new waterproofing system was designed and composed of a tapered insulation system to direct run-off to existing drains.

Phase III: Design services for this phase included producing contract documents to remove old caulking and install new caulking at all window joints, concrete joints and brick masonry joints.  In addition, masonry brick repairs were addressed throughout the building structure. During the construction a structural evaluation was performed to determine the integrity of the brick back up prior to repairing the face brick.
