As a DBE/MBE Subconsultant to a major transportation Tri-Venture Team, BvF provided comprehensive preliminary and final design services for the MD Route 7 Fish Passage Site. BvF conducted a preliminary analysis of bridge construction in lieu of culvert replacement, monitored the Subsurface Utility Engineering survey, and developed the Preliminary Utility Plan. They performed traffic data collection services, including turning movement counts at four signalized intersections and a 24-hour volume count at one location. During the Design Phase, BvF prepared bid-ready bridge design plans, specifications, and Engineer’s Estimates, ensuring compliance with MDOT SHA standard specifications and guidelines. BvF also developed the pre-bid CPM baseline construction schedule using Primavera P6.

The existing culvert, consisting of four 5-foot diameter corrugated metal pipes with concrete headwalls, was replaced with a single-span concrete slab bridge to improve fish passage. The new bridge spans 46 feet and consists of ten 4-foot wide concrete slab beams with transverse post-tensioning, providing one 11-foot wide travel lane and a 7-foot wide outside shoulder per direction. BvF prepared the TS&L (30% complete) package, finalizing bridge geometry and furthering calculations for the superstructure and substructure. They advanced to the Foundation/Structural Review (60% complete) stage, completing all structural plans and developing draft special provisions. BvF then completed the Final Design (100% complete) package, incorporating comments from MDTA and MD SHA, and delivered the Final Construction Bid Plans, Special Provisions, and updated Construction Cost Estimate to MDTA.
