Micropiles

Brayman Construction Corporation (Brayman) was subcontracted to provide specialty geotechnical construction services in support of the Elmhurst Innovation Center project located in Pittsburgh, PA.
The Mon/Fayette Expressway, a critical infrastructure project with planning origins tracing back to the 1950s, continues its development toward completion. The Brayman Construction Foundations Division, was subcontracted by Trumbull Corp to execute the installation of micropile foundations for the latest section of this expansive expressway, Section 53A1.
Brayman was contracted to provide specialty geotechnical services to Heartland Homes, Inc. for this residential land development project located 15 miles south of Pittsburgh at the Hiddenbrook Development Plan in Peters Township, PA.
Brayman Foundations Division was subcontracted to provide a Design-Build micropile foundation solution for the new U.S. Customs and Border Protection (USCBP) Integrated Design and Construction/Design Learning Center (IDC/DLC) Facility in Harpers Ferry, WV.
The work included the reconstruction of overpass connections to Fort Pitt Boulevard, and construction of a new three-span bridge and ramps.
Erected just upstream of the old bridge, the new 1096lf structure is a three-span steel haunch plate girder design carrying two lanes of traffic plus an eight-foot wide sidewalk.
Work involved the installation of deep foundation systems requiring in excess of 5,000 driven H-piles (over 75 miles) and nearly 300 micropiles.
At the time one of the largest micropile projects completed in the US. Over 1600 micropiles and Low Mobility Grouting installed in karst Limestone as part of a 320 million dollar plant upgrade.
Brayman was contracted by PennDOT to widen PA State Route 28, section A50, located near downtown Pittsburgh.
When a portion of the northwest wingwall collapsed, the Maryland DNR and DGS contracted with Brayman for an emergency stabilization. The remediation included salvaging the original facing stones, removing the existing bridge deck, and excavating 9 feet below deck elevation.
The new 130-feet long two-lane bridge consisted of a single-span steel beam five-girder structure with new abutments supported by drilled caissons and rock anchors.
Nine 5/8th inch micropiles were installed under an active high-speed rail line with no interruption to rail service.
Brayman was contracted by a midstream operator to complete the micropile installation at their new gas processing Cryogenic and De-Ethanizer facility located in Washington County, PA.
The project required the installation of 578 micropiles with diameters of five and one-half-inch, seven-inch, and nine and five-eights-inch, and depths ranging from 30 feet to over 100 feet.
Installation of 21 micropiles through the existing footer and 24 tiebacks through the existing wall. The micropiles and tiebacks will be tied together with a new retaining wall poured in front of the existing retaining wall.
