According to the San Francisco Parks Alliance, Indian Basin Waterfront Park is one of the most significant park projects in San Francisco's history. Once completed, it will transform a post-industrial brownfield in a historically underserved community into a 10-acre waterfront park with an emphasis on public access, social equity, resiliency, and restoration.

Power is the project's marine contractor, undertaking shoreline fortification, installation of deep soil foundations for near-shore structures, and construction of a 180-foot-long seawall designed to withstand future sea level rise. Additionally, two expansive cast-in-place concrete piers are being erected, along with the installation of a fishing dock float and gangway with wood decking. This blend of heavy-civil and marine components not only contributes to shoreline sustainability but also fosters a critical link between the community and the water, effectively transforming previously inaccessible areas.

The work involved installing 92 square concrete piles, ranging in size from 24-inches to 16-inches square. However, the very first day of pile driving marked the emergence of an unforeseen challenge. Beneath a thick layer of sand that had been added atop native soil as a crucial part of the site's remediation efforts was a dense sand lens that rendered original pile installation means unfeasible. Project constraints prohibited removal of soil under the remediation sand cap, so a larger impact hammer was required and used in conjunction with the original means and methods. With less than a month left in the permitted in-water work window, the construction team needed to act fast in developing an alternate installation plan and putting it into action.Accomplishing the task extended the required hours by 30%. Undaunted, our crews rallied and worked double shifts until they were back on the original critical path schedule.

The project's success serves as a testament to the unwavering determination and expertise of our engineering team, who overcame unexpected challenges and are delivering a resilient, community-enriching marine construction project to the beautiful city of San Francisco.
