Problem
Construction of a 6-story parking garage and adjacent to a module block wall on the footprint of an existing parking lot required a skilled excavation company – all of which was complicated by discovery of a live water main and electrical duct bank underneath.
Solution
- Handheld GPS and careful site review to confirm location of a live water main and electrical dock prior to rerouting
- Smart, GPS, software-enabled bulldozers and excavators ensured fast and accurate grading and site cuts
- Careful coordination and timing among electrical, plumbing and construction contractors
- Background check and security clearances for managing spoils transportation from landside to airside dump site
Impact
Streamlined communication and a unique contract model eliminated scope gap concerns for the general contractor and ensured successful navigation of unforeseen challenges and material change orders.
