We’ve established Helical Drilling as one company with a multitude of solutions. Comprised of geotechnical engineers, construction managers and field crews under one roof, we are the premier turn-key firm for all of your geotechnical design/build construction needs.
Check out some of our recent work below.
The 170 West Broadway Street Project, built on a 16,800 SF site in South Boston, houses a 5-story mixed-use structure and a single-level underground parking garage extending below the water table. To overcome the high water table, zero lot line support against neighboring structures, and to virtually eliminate construction vibrations, the design team elected to use a dual-purpose secant pile wall system to serve as both the excavation support system and the permanent foundation wall.
A 5-story precast parking garage experienced at least three inches of post-construction differential settlement and required a fast and innovative solution to limit further damage to existing architectural features while limiting any additional structural damage. Rather than removing and replacing an existing footing, a compaction grouting underpinning solution allowed for the existing footing to remain in place, a fast construction schedule, and significant cost-savings.
A new pedestrian bridge over the Shepaug River in rural Washington, Connecticut required a foundation support solution capable of resisting significant compression and tension loads. A combined rock anchor and drilled micropile solution was used to support the walkway path upgrade on the 150-foot bridge.
Helical piles were used to support a new, one-story retail glass pavilion adjacent to Quincy Market with structural column loads ranging from 30 to 60 kips. Primary project challenges included construction in a sensitive, historic tourist area; limited construction access; and difficult subsurface soil conditions that are common along Boston’s reclaimed waterfront.
A historic hotel located in Boston’s residential Back Bay neighborhood required extensive renovation work to transform the building into a luxury condominium complex. The work included a new elevator and car lift which required drilled micropiles to support the added load.
