Goodman Building Renovation and Expansion

COLLABORATION 3, LLC GOODMAN BUILDING RENOVATION AND EXPANSION ONE EAST BROAD STREET, SUITE 310, BETHLEHEM, PA 18018

In 2018, Collaboration 3, LLC was selected by the City of Bethlehem to redevelop the deteriorating and mold infested Goodman Building. At that time, four of the 13 major wood roof trusses had collapsed onto the third floor and water from the leaking roof and walls had been freely saturating the building interior for some time. The water was also penetrating the adjacent buildings through the common walls. As a result, the majority of the remaining trusses and multiple floor structure areas were badly decayed and in danger of collapse. Exterior masonry walls were bowed out of plane and cracked raising concerns regarding their stability and the safety of adjacent sidewalks and buildings. The building was full of contents including papers, boxes, clothing, equipment, furniture, books and other items. Due to the long-term exposure to moisture and high humidities, essentially all contents including the building walls, floors, and ceilings were covered with mold. BACKGROUND

STABILIZATION

The immediate and urgent scope of work included temporary stabilization of the roof and side walls of the building, and repairs to the collapsed and deteriorated roof and floor areas to allow safe access for demolition of deteriorated structural elements and implementation of a mold remediation plan. Structural steel beams, joists and steel deck were installed to frame in the new roof. Deteriorated floor structure areas were replaced. Areas of exterior brick masonry were rebuilt to correct bulges and cracks caused by roof truss collapses. Brick repointing work was performed to repair deteriorated mortar and fill in areas of missing mortar on exterior masonry walls and permanent bracing was installed above the roof level to stabilize masonry parapets. A completely new roof structure, decking, insulation and EPDM roof membrane were installed to make the building watertight. Removal of all contaminated building contents was performed concurrently with the above noted restoration work. This included removal of all contaminated plaster ceilings, wood soffits, and wood and drywall partition walls. Dehumidification and a final cleaning of all interior floor and wall surfaces was performed when the building was watertight.

REPURPOSING & HISTORICAL IMPACT

Although much has been achieved to stabilize the building structure and interior building conditions, there are a number of building core and shell items that have yet to be completed. This next phase of the project will include additional masonry restoration work, removal of delaminating sections of exterior stucco, installation of newwindows, restoration of the three cornice areas, installation of floor framing and decking in areas not completed during the initial phase. Exterior restoration work will be performed to capture the historical character and aesthetics of the original Goodman Furniture building. In addition, a new permanent HVAC systemwill be installed to condition the building and maintain stable temperatures and humidities, which will prevent the return of microbiological growth. New electric, fire alarm and data systems will be installed, as well as new plumbing and fire protection systems. Newwalls and ceilings will be provided, and all floors will be made handicap accessible with a new elevator and stairs.

COLLABORATION 3, LLC

In addition to finishing the core and shell of the existing building, a new four-story structure is planned for the adjacent lot. The challenges encountered on this site include an existing subsurface littered with debris from the demolition of a building that existed previously on the site. A geotechnical investigation discovered deleterious fill materials such as wood, brick, pieces of concrete, slag and gravel in the upper 10 feet of the building pad area. As a result, deep foundations in the form of helical piles will need to be installed to support the new building. There will also be replacement of the top layers of this nonstructural material to support the new building slab on grade. The new building will incorporate state of the art technology as well as all the expected amenities associated with a revitalized south side development. The new building will provide considerably more window area, while complimenting the historical appearance of the existing structure.

Collaboration 3, LLC has already spent $1.9 M on stabilizing the building, structural repairs, and mold remediation. The overall estimated expenditure is an additional $9.8 M to complete the stabilization and establish a useable existing building as well as the construction of the new addition including all of the required work for the core, shell, and fit-out for both. The initial estimated core and shell expenditure is $4.3 M. INVESTMENT

COLLABORATION 3, LLC

The direct investment by Collaboration 3, LLC for this work is anticipated to be $2.3 M for this portion if the project is successful in obtaining a RACP grant of $2 M to support the extraordinary costs as a result of the complexity, challenges, and deteriorated nature of this historic building.
