Holtwood Boat Barrier

Project consists of 60,000 CY of rock excavation, 65,000 CY common excavation, over 100,000 CY embankment material, 90,000 CY of mass concrete and over 1,150 high capacity dam anchors. It will also include a grout curtain and reconstruction of the left and right river banks.

A sheet pile cofferdam was installed down the center of the existing stilling basin to divide the spillway in half in preparation for the Phase 5 Spillway Reconstruction Project.

Brayman was contracted to provide specialty construction services in support of the Dam Safety Assurance (DSA) Phase 3 Project at Bluestone Dam.

Post tension anchors, spillway access platforms, underwater anchors, increased dam height via post tensioned pre-cast panels, 2 mile access road, shoring, caissons, soil nail wall, this job had it all.

This project involved the installation of 212 high capacity rock anchors, ranging from six to 61 strands, to upgrade the stability of the existing dam.

Brayman was contracted to install underwater anchors to hold a new half mile long boat barrier.

Brayman Construction was contracted to install five, 61-strand, restressable anchors to drill depths up to 195 feet in a monolith of the lock chamber at Chickamauga Lock and Dam in Chattanooga, TN.

Brayman was subcontracted to install a 5719 SF soil nail wall as part of a spillway expansion project at the North Fork Dam near Black Mountain, NC. Both soil nails and tieback anchors were installed on this wall which served as a slope stabilization measure for construction of a permanent access road on the site.

The Prettyboy Dam project involved the installation of an underwater anchorage system necessary to secure the concrete gatehouse to the dam.

This project consists of four and one-half feet drilled Shafts at the abutments and six and one-half feet drilled shafts at the river piers.

The dam received a structure upgrade in 2018, which included over 16,000-cy of mass concrete, 68-ea high capacity dam anchors, and 175-ea drains.

Twenty-three post tensioned dam anchors were installed to upgrade capacity of the dam while working around multiple other sub-contractors in very tight access.

The modernization effort at this site will ultimately result in the construction of two new 84-feet wide by 720-feet long chambers to replace the existing 56-feet wide lock currently in operation.

The Allegheny County Sewer Authority awarded Brayman the emergency procurement contract to repair and replace the A-34 Diversion Structure located along the Allegheny River in the Lawrenceville neighborhood of Pittsburgh, PA.

This award winning new bridge is a cable stay structure with 326’ tall delta shaped towers and a 900’ main span (the longest span ever constructed by ODOT).

The Pennsylvania Department of Transportation’s Replacement of the Hulton Bridge near Oakmont, PA, involved the replacement of a two lane truss bridge with a new 1,633 LF four lane five span haunched girder bridge erected upstream of the existing bridge on the Allegheny River.

The Lilly Bridge project involved replacement of a cantilever truss bridge with a new 1,220-LF five-span, fabricated steel girder bridge.

The new 338-feet long two-lane bridge was constructed with the substructure founded on cast-in-place concrete pipe piles.

The project scope involves building seven, separate precast concrete structures offsite, then loading the segments onto barges, delivering them to the job site, and assembling them into place, under water, using floating A-frame cranes.

The Masontown Bridge project involved the replacement of an existing 11-span, two lane steel truss structure with a new 1,700-LF 7-span four lane plate girder bridge.

The project consisted of two phases. Phase 1 involved the installation of an anchored sheet pile retaining wall and the installation of eight 120-inch diameter caissons. Phase 2 included the installation of structural steel beams and the construction of a 120-foot by 46-foot concrete deck.

Brayman was selected to install 50 epoxy coated dam anchors, which upgraded the structure to current federal dam safety standards.

Not only was our team able to prevent the roadway from sliding into Ten Mile Creek, we also prevented an ensuing road closure accompanied by a 35-mile traffic detour.

Brayman was contracted to install precast concrete coffer boxes around the pipe to allow for easier access to the pipe for cleaning operations.

The Ices Ferry Bridge project involved the replacement of a steel through-truss bridge with a new 960-LF four-span steel girder bridge located near Morgantown, WV.

This project exemplified Brayman's ability to offer "one stop shopping" for construction services by featuring several capabilities including high capacity dam anchors, temporary shoring, and driven piling.

The new River Wall project is a component of a larger effort to improve and modernize the navigation facilities on the Lower Monongahela River between Braddock and Charleroi.

Brayman was contracted by the WV Division of Highways to construct a new 2,975’ long concrete segmental bridge outside of Charleston, WV to carry eastbound I-64 over the Kanawha River.
