Analysis
On August 16, 2016 the City Council awarded the Construction Manager at Risk (CMAR) contract to Modern Contractors for pre-construction services for the Prairie Paws Expansion project in the amount of $1,000. This award provided the CMAR services including development of project estimates, preliminary construction schedules, value engineering and constructability review during the Design Phase.
The current Change Order/Amendment No. 2 in the amount of $218,121 is divided as follows:
1. $3,636 for demolition of concrete foundations and slab on the north side of the building to facilitate new slab design required per exposure of existing conditions
2. $73,130 for revisions to a plumbing flow line inside the existing building and adding a new 6” sewer service to connect to the sewer main on the south side of Warrior Trail due to existing sewer elevations being higher than anticipated
3. $139,855 for changing structural belled concrete piers to steel helical piles at the north and east expansion areas due to the presence of ground water
4. $1,500 for providing, installing and removal of temporary ceiling grid and tile in existing facility east corridor due to need for maintaining air conditioned environment with the presence of animals while still in operation
Change Order/Amendment No. 1 in the amount of $5,090,953 was approved by City Council on March 7, 2017 and represented the project GMP after subcontractor bids were received and analyzed for scope coverage.
All items will be incorporated into the current Modern Contractors contract for a revised total contract amount of $5,310,074.
