Hamilton Township Bridge 5

Bridge 5 – Strawberry Hill Road Over McMichaels Creek
Hamilton Township, Monroe County, Pa.

RKR designed a new bridge to replace a 66-foot span that was determined to be structurally deficient. During the preliminary design stage, we investigated superstructure alternative types and conducted a geotechnical investigation to determine the most suitable foundation. The final structural design of the bridge included engineering designs for the the beam, reinforced concrete deck, abutment and wingwall, riprap, and foundation. The bridge was designed in accordance with PennDOT DM4 (Structures), and satisfies current legal vehicular loading at operating levels. In addition, we prepared the construction plans and specifications, and performed construction administration and observation services.

Glendon Borough Sewer System

Glendon Borough Sanitary Sewer Extension
Glendon Borough, Northampton County, Pa.

RKR is providing professional engineering services for an extension of the Glendon Sewer system in District III. The project consists of the design, permitting, construction administration, and construction observation of a sanitary sewer system and forcemain, and sewage pumping station. Additional design items include a generator, automatic transfer switch and associated laterals, excavation, backfill, site/grading improvements, erosion and sediment controls, pavement restoration, and traffic controls.

Voltaix Land Development

Site Design Services for Industrial Land Development Project,
Upper Mt. Bethel Township, Northampton County, Pa.

This project was to develop the Industrial Land Development Plan for a manufacturing facility on a 27-acre project area. The site plan consists of multiple buildings and structures, driveways, parking areas, utilities, stormwater management facilities, and related items. For this project, we conducted a boundary and topographic/existing features survey; provided site design for utilities, stormwater management, etc.; and provided construction observation of the stormwater and erosion and sediment control measures. We also developed Operation and Maintenance Programs for the construction phase and for long-term sustainment post-construction.

East Stroudsburg Dam

Middle Smithfield Township, Monroe County, Pa.

RKR provided dam rehabilitation design services, including overtopping protection, spillway replacement and repairs, drawdown system repairs, and stabilization measures. Design elements included modifications to the existing dam and appurtenances, erosion and sediment pollution control, grading, access, staging areas, drawdown siphon, and drainage system flow monitoring stations. Additionally, we designed a half-acre wetlands replacement site. RKR prepared permit applications and plans for approval, including a PA DEP Dam Safety Letter of Authorization, a NPDES Permit for stormwater discharges, and an ESPC Plan. RKR also prepared applications for a PA H2O Grant and a PennVEST Loan, and managed payment applications.

For this project, RKR was honored with the 2012 Outstanding Civil Engineering Achievement Award from the Lehigh Valley Section, American Society of Civil Engineers.
