COR 9: Interior Layout Changes
After demolition a structural support column was discovered to conflict with the women’s restroom entrance.
This change effected the location of the mop sink closet, women’s restroom, and men’s restroom. The work
necessary for this change included some underground plumbing rework, wall relocation and replace floor slab
concrete. The men’s and women’s restrooms were swapped as a result of this change to make both restrooms
comply with building requirements.
COR 14: Rubber Floor Credit
During the submittal process it was determined that a credit could be issued to the City to install an epoxy
floor in the ticketing room, employee breakroom, and employee restroom. The contractor has proposed a
credit for the rubber tile floor that is in excess of the cost of epoxy flooring.
COR 17: Temporary Heat
Currently the City is providing fuel payments for a temporary heating system installed by the contractor. This
change would include installing temporary electric heat in the transit center while work is being performed.
Although the new furnace has been installed, it cannot be activated until construction activities are complete
as to not damage the filters. The electric heat option would be a more consistent heat source and eliminate
the need for portable fuel tanks on the premises. It will also allow the contractor to remove the temporary oil
burner from the platform areas that will soon be open to the public.
COR 18: Ticketing Casework
The contract originally called for the casework in the ticketing area to remain. However, the contractor had to
install bullet board behind the casework. Due to the age of the casework, the contract was unable to remove
the casework without it being permanently damaged. Understanding pre-construction condition of the
casework, new casework should have been part of the base contract.
COR 19: Attic Hatch Change
During a permit review by City of Nashua Building Safety, it was requested the attic stairs be changed for a
hatch opening. This change involved a credit for the actual stair unit and a cost increase for the new trim
needed for hatch detail.
COR 20: Employee Breakroom Mold Remediation
What appears to be black mold was discovered on the existing drywall in the employee breakroom. As this
drywall was scheduled to remain in place, the City requested a proposal from the contractor to remove mold
dry wall and replace.
COR 21: New Drywall for MEP Blocking
With some of the interior changes, a vertical grab bar and toilet partitions were added to the exterior wall in
the women’s restroom. The contractor was asked to propose new drywall instead of attempting to install
various patches and try to blend new patches into old previously damaged walls. With the existing drywall
being in poor condition, new patches would not be aesthetic or suitable.
COR 22: Ceiling Reframing
Change Order #3 2 of 4
