Construction

• New Construction
  McCormick Taylor supported MDOT SHA by providing design and construction services from concept to final construction closeout for this safety and infrastructure improvements project. CLICK HERE TO LEARN MORE
• Demolition
  McCormick Taylor continued the development of the parking expansion by completing both preliminary and final design services for the project. Hydraulic-related tasks associated with the preparation of the demolition project and parking expansion design include storm drain analysis and upgrades of existing and proposed systems, stormwater management analysis and Environmental Site Design (ESD), Low Impact Development (LID) Design, and erosion and sediment control design.

Landscaping and Fencing

• Landscaping
  McCormick Taylor also worked with Howard County to coordinate with the adjacent homeowners on landscaping preferences and business owners to provide adequate accessibility for their business needs.
• Fencing
  McCormick Taylor worked collaboratively during project development with two state agencies, PennDOT and PA DCNR. Their input related to design, landscaping, features like fencing and railing, aesthetics related to the stone on the underpass, and other coordinated design items resulted in a unique project.
• Driveways
  A significant challenge on this project was designing adequate connections from the reconstructed roadway on the north end of the project to several driveways on properties that were several feet higher than the roadway.  In addition, the project area included a considerable amount of substandard soils that were going to be encountered during construction.
• Retaining Walls
  Geotechnical investigations were completed to determine a constructible approach to retaining wall designs for the staircase to be built into the existing slope while maintaining traffic on the roadway above during construction.
• Irrigation Systems
  McCormick Taylor and the design team evaluated the J-Turns and Continuous Green T-intersections to ensure they were wide enough to accommodate large farming equipment while addressing safety concerns throughout the corridor. The project team collected feedback from the affected property owners and worked with regulatory agencies to help reduce the impacts to the residents and farming community. This included using a different methodology for calculating stormwater management requirements to reduce the need for the large stormwater ponds, which impact prime farmland and irrigation systems.

Exterior

• Decks
  The I-95 and U.S. 202 interchange in Wilmington experienced severe traffic congestion and accident rates for years. Built in the mid-1960s, its concrete pavement and interchange bridge decks deteriorated over time.
