At the t ime of this Tremie grouting a micropile discovery, Hayward Baker had already begun scaling back resources on site due to the limited areas available for work around the other ongoing construction acti- vities. The planned demobil- ization was halted and additional resources were quickly mobilized to the project site. This included additional personnel, an additional drill rig and ancillary equipment, and tooling to support seven operating drill rigs. The general contractor, dck- FWF, res t ructured the project schedule and other subcontractors to accommodate the necessary access for the remediation efforts. The final installation and remediation of the micropile foundations was completed in early January 2015, two months after discovery and one month after agreement on the remedial action plan was reached. Keys to Success The installation of the micropiles at IMP had significant difficulties and constraints: highly variable substrata, live trees protected in place, archeological concerns, working on an island, artesian ground water, complex critical path schedule, and the list goes on. These Work progresses on the IMP site significant challenges were met by a diverse project team that worked cooperatively with the project’s goals clearly in focus. The use of a design-assist concept with the foundation contractor provided a unique atmosphere of technical cooperation, to the benefit of the project. The project team members met weekly throughout the project to discuss the current and upcoming challenges. The agreed goals and open communication created a partnering environment between the contractor, owner, consultants and specialty foundation contractor to ensure performance in safety, quality, financial control and schedule.
