We see the new duct bank going through existing sidewalks, curb and gutter, roadways and parking lots but did not find any division 32 specs to go with the work. Can the VA provide them?

The VA estimated schedule for site work/Duct bank and restoration seems short for the extent of work considering possible relocation of existing utilities and shutdown requests duration for existing utilities. Can this be adjusted to add for utility shutdown request period?

VA estimated schedule is a comparison tool for this project. Contractor shall follow SPEC 01 32 16.15.

Please advise if sitework for duct banks will be performed during winter (note that VA estimated schedule of May 2025 has already passed for sitework). If this is winter work, then the schedule needs to be adjusted further to cover for weather conditions.

1. Per VA estimated Construction Schedule included in the RFP, the duration for installation and completion of activity ‘Install Communications System’ seem to be short (ex; Bldg 1, Level 1) which shows duration of ‘Communications Install’ at 10 days only. If this pertains to the whole ground floor (Bldg 1, Level 1), this is definitely not enough considering installation of new conduits and cabling for all the rooms. Please confirm if this is for the TR rooms only and not for the whole floor (Ref. Sheet B01-TN101A). The duration of 10 days will not be enough for the whole floor. Please advise and adjust schedule to include installation of conduits, and comms wiring for each floor rooms. Note that this will increase construction duration in consideration of adding durations for installation of data/comms to each room per floor and buildings.

Contractor shall provide the final schedule. VA schedule is an estimate. A time modification will need to be submitted and approved.
