2500 Smallman Street

2500 Smallman was renovated from a one-story warehouse into a three-story luxury townhouse development that the developer right-sized to 11-units and three stories despite zoning approvals for a larger project.

Renovation required vertical expansion and creation of an open central motor court, which used 420 tons of structural steel, 16 tons salvaged from the motor court. A steel-framed suspended boardwalk spans the motor court.

Site constraints required all steel to be raised from inside the building and limited options for ingress/egress.

The use of BIM and UAV video allowed seamless coordination between engineer, architect, and contractor from evaluation through construction.

The renovation was designed to meet LEED Gold standards and is currently being evaluated by the USGBC for certification.

Lancaster Central Market

WBCM provided structural engineering services for renovations to the Lancaster Central Market. Renovating that 1889 Romanesque Revival building that houses the country’s oldest farmers market was a major structural challenge.

Renovations included the addition of a 2,000 square foot basement, which required underpinning and reinforcing the existing loose-laid stone foundation walls and extending the four-story southeast tower walls to the basement for stairway access. The basement included new mechanical and electrical systems, as well as vendor storage closets and cold storage.

WBCM designed a second-floor mezzanine adjacent to the southeast tower that houses an employee lounge area and an observation platform looking out over the market floor.

WBCM also completed an evaluation of the roofs timber truss system for conformance with current building code requirements in conjunction with restoration of buildings slate roof.

The market remained operational during the entire construction period.

Montgomery House

WBCM provided engineering services to facilitate interior renovations of a three-story, wood-framed building built in 1803, which is annexed to the Lancaster County Convention Center. Interior renovations included complete removal and reconstruction of interior floor framing to upgrade floor capacities for meetings and social gatherings, installing an elevator, and other ADA requirements to link the building to the convention center. The main stairway was completely removed and structurally rebuilt to conform to code requirements. Modifications to the attic and roof framing included the reconfiguration of roof trusses to create more usable space in the building.
