2 S. Broadway Vault Infill

Infilling of the underground vault located beneath the sidewalks along both Broadway and Galena in accordance with Project Plans and Specifications prepared by Fehr Graham. Scope includes removal and replacement of portions of concrete sidewalk and supporting structural slab for access, removal of abandoned utilities and partition walls within vault as necessary, relocation of sump pit, reinforced concrete wall construction (including concrete floor/bedrock removal for footings), flashing, waterproofing membrane, and infilling. The base bid for this project assumes the removal and replacement of approximately 10% of sidewalk/structural slab to facilitate infilling with Controlled Low Strength Material (CLSM). For flexibility in the event that this scope proves to be cost prohibitive, the City is also requesting bid alternates to: 1. Remove and replace approximately 50% of sidewalk/slab to facilitate infill using CA-7 for the portion of vault along Broadway only. The remaining portion of the vault (Galena) would be infilled as specified in the project plans and specs (base bid scope). Installation of a non-structural partition wall/form would be required between the vault sections to allow for proper infill. 2. Remove and replace approximately 50% of all sidewalk/slab to facilitate infill using CA-7 at all locations. Prior to commencement of construction, the City will conduct the necessary asbestos and lead paint survey and abatement (if necessary) for all materials to be disturbed as part of this project.
