1. Walnut Street Extension

    RETTEW helped revitalize a dormant roadway project, which was started by PennDOT 40 years ago as the Route 23 bypass, but was abandoned because of funding challenges. The neglected corridor — colloquially dubbed the “goat path” — had been partially constructed and subsequently reclaimed by nature and repurposed by local farmers for grazing. This present-day…

  2. Artswalk Pocket Park

    The original pocket park was created to cover a proposed stormwater best management practice that was built in an urban parking lot. Surrounded by alleys open to traffic, the original park was graded to fit between them and, as a result, had a fairly steep slope that rendered it useless for any active use. After…

  3. Hatchery Road Over I-476

    This was the pilot bridge replacement project for the Pennsylvania Turnpike Commission’s (PTC) Bridge Information Modeling (BIM) and Digital Delivery Program, which included developing a 3D model. The existing bridge was a single-span steel beam bridge, and we proposed a two-span composite prestressed spread box-beam bridge. This project was part of a $1.5 million open-end…

  4. Farmdale-Ferndale Storm Sewer Improvements

    West Hempfield Township was looking to pave the streets in one of its neighborhoods as part of a capital improvement project. The neighborhood was built in the 1970s and the existing stormwater infrastructure was also in need of repair and/or replacement. RETTEW worked with the Township to analyze the existing pavement, curbing, and stormwater facilities…

  7. Rhode Island Row Solar Array

    A team of solar developers was looking to install rooftop and carport solar arrays on two mixed-use commercial buildings in downtown Washington, D.C. to benefit lower-income residents in the D.C. area. RETTEW was the ideal candidate to make this goal a reality because of our vast experience in designing solar arrays, as well as general…

  8. Tower 6

    Downtown Allentown is thriving because of its recent revitalization efforts and is quickly outgrowing its supply of office space. To address this need, City Center Investment Corporation (CCIC) is developing the City Center Lehigh Valley project, which is fast becoming the region’s hub for business, culture, and urban living. CCIC has worked with RETTEW on…

  9. Salt Water Injection Well Facility Site Characterization and Remediation

    Our client, planning to sell their property, received a compliance notice from the Ohio Department of Natural Resources (ODNR) requiring remedial actions. Historically, the site was contaminated by chloride, petroleum hydrocarbons, and technologically enhanced naturally occurring radioactive material (TENORM). Impacted soils, building materials, and equipment required demolition and excavation to restore the site for regulatory…
