driven piles and CIP footings. Through this effort, the footing sizes
throughout the building were reduced by over 13 percent.
Access to the site was limited. To minimize the impact to the
surrounding public, piles were transported to the project during off
peak times and the material was 100 percent staged prior to construction.
Stable crane access/pads were constructed to allow the
crane to navigate through the soils made soft due to melting snows
and the high water table. Furthermore, the aggressive nature of the
design and the discrepancy in elevations between the parking and
office buildings caused several different bottom of footing elevations.
RLW utilized a Manitowoc 12000 and 1-30 diesel hammer
on swinging leads to access the separate drive locations.
RLW met the challenge of this difficult job and used cost savings
and value engineering methods in the design and construction
of the driven foundation pile system. Both the client and owner
recognized the cost effectiveness of replacing the ACIP piles with
the driven foundation piles and appreciated RLW’s quality of work
and their ability to meet a demanding project schedule in a safe and
productive manner.
When overall excellence is discussed concerning large deep
foundation projects, partnering with the owner and stakeholders
must be at the forefront. RLW’s relationship with its owners and
general contractors is second to none due in large part to the open
communication and close collaboration maintained throughout the
project. The project issue log never carried more than five items at
any one time and project completion showed less than twenty-five
total issues logged. The success of this project is a testament to the
close collaboration within the project team and an excellent example
of how the simplicity, durability and flexibility of driven piles
still reigns supreme in the deep foundation marketplace. t
