The Ware River slope stabilization project involved the construction of a new retaining wall to reinforce a failed slope in New Braintree, MA, along the Right-of-way of an active railroad corridor. The original design provided by the client included a drilled soldier pile and precast lagging retaining wall. Manafort worked with the owner and designer and provided a value engineering design that changed the wall to a driven pile with cast-in-place concrete pile cap and precast concrete block retaining wall. With the change in wall type, a credit was issued and approved by the owner.

The project was only accessible by hi-rail equipment so all equipment and materials were transported by Manafort via hi-rail equipment from a nearby grade crossing to the project site. The project consisted of 39 HP 14×89 driven piles, a cast-in-place reinforced pile cap, 2,067 SF RECON block retaining wall, rip rap slope stabilization, and wetland restoration.

Manafort served as Prime Contractor for the project and self-performed a majority of the work, including the driven piles, retaining wall installation, all hi-rail equipment moves, and rip rap slope stabilization.
