The Bottom Line: HJ Foundation, in a joint venture with G. Donaldson Construction, a division of Hayward Baker, assisted the client in a value engineering solution to reduce the number of augercast piles by 10%.  HJ’s state of the art equipment powered through challenging subsurface conditions to successfully complete the project ahead of schedule and under budget.

 

HJ Foundation - augered piling stamford connecticutValue Engineering:

HJ Foundation aided the Owner’s request for a Value Engineering solution to reduce the overall project budget.  HJ proposed higher capacity augercast piles than originally specified.  Higher load bearing capacities per pile resulted in a pile quantity decrease of 10%.

Guaranteed Schedule:

Schedule savings resulted from the decrease in number of foundation piles due to our Value Engineered solution.  HJ Foundation also committed to an aggressive 4-week production schedule to install the final total quantity of 596 piles.  HJ Foundation completed all piles in 14-days, over 1-week ahead of schedule.

Quality and Expertise:

HJ Foundation utilized its powerful equipment to successfully install pile load tests which proved additional reserve capacities for the augered piles.  A high occurrence of immense boulders and other obstructions added a challenge to the installation of piles, but HJ’s state-of-the-art equipment powered through and installed all piles to meet and exceed project specifications, with zero delays to the overall schedule.  Obstructions prevented a few piles from being installed in the exact design locations, however, HJ performed overload tests to prove a reserve capacity for the piles, allowing the shell contractor to form and pour the pilecaps as scheduled, without remedial work being specified, further helping the overall project schedule.
