| Harvard—Allston Science Complex, Allston, Mass.
Geocomp is providing installation and monitoring services for Harvard University’s new Science Complex, at the Allston campus. The Science Complex includes four building components and approximately 530,000 sq. feet of above-ground floor area. It also includes shared research support facilities below-grade, an underground distributed energy facility, loading and mechanical facilities and below-grade parking. Geocomp's services includes installation of inclinometers and extensometers for monitoring global stability of the excavation, automated total stations for automatically surveying excavation support wall and adjacent ground and structures, and load cells for tie-back monitoring. Geocomp is utilizing seismographs with automated data reporting for the project. The data is being made available to the project team through Geocomp’s web-based reporting system, iSiteCentral.

Ellis Square Parking Garage, Savannah, Georgia
Geocomp was retained to advise the design-build team to devise ways to minimize impact on historic buildings surrounding the Ellis Square parking garage excavation in the center of the city of Savannah, Georgia.

Geocomp worked with the project team to devise a way to complete the 45-ft. deep underground parking structure with minimal movements to adjacent structures.

Geocomp personnel defined and characterized the layers of soft clay detected below the bottom of the excavation using cone penetration tests, continuous split-spoon, and Shelby tube sampling. Geocomp’s subsidiary, GeoTesting Express, completed direct simple shear and constant rate-of- strain consolidation tests to define the appropriate soil properties for analysis of global stability and future deformations.
Geocomp installed a state-of-the-art real-time monitoring system using Leica automated total stations with reflective targets and in-place inclinometers to monitor movements of the excavation support system and adjacent buildings around the clock.

This project required close integration of Geocomp’s expertise in soil properties, advance numerical analysis, real-time monitoring, and risk management to help the client find a way through this serious setback.
| North Dorchester Bay Combined Sewer Overflow (CSO) Tunnel and Facilities, Boston, Mass.
Geocomp is providing installation and monitoring services for the Massachusetts Water Resources Authority’s project to construct a 17-ft. diameter, 2.1-mile long soft ground tunnel in South Boston. This tunnel will virtually eliminate combined sewer overflows and storm water discharges to the beaches in South Boston. The tunnel will be constructed using a tunnel boring machine (TBM) and is expected to be completed in 2009.
Geocomp is installing borehole extensometers, observation wells, deep bench marks, vibrating wire piezometers, in-place inclinometers, and more than 10,000 feet of surface and building monitoring points. Geocomp is also collecting data from 500 sensors located on the TBM. This data, which must be updated every 3 seconds, is being processed through Geocomp’s iSiteCentral data management system.
