Crystal Bridges Expansion

Project Overview

As part of the Crystal Bridges Museum expansion project, Emery Sapp & Sons (ESS) performed critical earthwork, excavation, blasting, utility, and site stabilization operations that enabled construction of the new expansion while protecting the integrity of the existing museum and surrounding environment. ESS’s scope focused on complex site preparation and infrastructure improvements adjacent to the occupied museum facility, requiring careful coordination, precision execution, and innovative construction techniques.

A key challenge involved extensive rock excavation and controlled blasting immediately adjacent to the existing museum structure, where valuable artwork and occupied spaces remained in use throughout construction. ESS implemented comprehensive vibration monitoring systems during blasting operations to continuously track movement and ensure no impact to the structure or interior finishes. Through detailed planning and controlled execution, all blasting activities were completed successfully with no damage to the museum or its contents.

ESS also completed major creek reshaping and earthwork operations throughout the site. The team excavated and widened both sides of the creek corridor while maintaining clean stormwater flow during construction. This process required temporary water diversion measures, including blocking and pumping water around the pond area, constructing temporary dams, and installing a new valve structure to hold back water during concrete placement operations. These efforts allowed crews to complete concrete flooring installations across the full creek area before safely restoring normal flow conditions.

Additional ESS work included installation and relocation of critical underground infrastructure systems, including sewer, sanitary, stormwater, and water line improvements. The team excavated and installed a new concrete storm box, extended storm pipe infrastructure, completed significant grading and backfill operations for lower basement areas, and constructed soil nail retaining wall systems along both sides of the excavation to stabilize the site and support safe construction activities.

ESS’s earthwork and infrastructure improvements established the foundation for the Crystal Bridges expansion while preserving the natural character of the site and supporting the long-term functionality of the museum campus.
