About this file

The document is a draft technical drawing set for a bridge abutment design by Vista Design, Inc. for the White Oak Village project, dated 10/26/23. The four-page technical drawing set provides detailed isometric, front, side, and geometric views of a bridge abutment, including specifications for concrete strength (4000 PSI), dimensions, reinforcing rebar placement, and anchor bolt configurations. The drawings specify a 7-foot wide abutment with a double 2x10 sill plate, 10-inch anchor bolts embedded 6 inches, and precise rebar reinforcement patterns including vertical #4 bars at 24" on center and horizontal #4 bars at 12" and 6" on center.

The technical notes provide critical implementation requirements, including that the bridge must be assembled and installed per manufacturer's specifications, with concrete inspection by a geotechnical engineer and Charles County prior to pouring. The concrete must comply with county standards and American Concrete Institute (ACI) specifications, have a minimum compressive strength of 4000 PSI at 28 days, and maintain a maximum water-cement ratio of 0.45. Additional specifications cover rebar conformance to ASTM A-615 standards, galvanized anchor bolt placement, stainless steel bracket connections, and precise installation instructions for attaching the bridge structure to the abutment and decking boards.
