About this file
This document is a Fencing Specifications Exhibit from the Maryland Department of Health, detailing technical requirements for a fencing project. The specifications cover a single-layered mesh fence system with a total length of 150 feet, 8-foot panel width, and 12-foot height. The project requires a mandatory site visit before proposal submission, with the fence terminating and anchoring to a building. Two post configuration options are provided (square and round), and the fence includes a 4-foot wide by 7-foot high lockable gate with specific installation requirements.
The fencing must meet rigorous technical standards, including ASTM F1043 Group IA Heavy Industrial Fence Framework specifications, schedule 40 galvanized pipe, and specific wire mesh characteristics. Additional requirements include a powder coat black finish, 3,000 PSI concrete footings, wind speed resistance up to 110 MPH, and a minimum 20-year warranty against manufacturing defects. The project emphasizes precise installation details such as fabric tension, ground clearance, and attachment methods, with no additional lighting or security cameras required beyond existing infrastructure.

Special condition: 1 (one) site visit required before submitting a proposal. Contact the hospital representative to set up a site visit date. The termination of the fence will be anchored to the building. The Fence needs to drop underneath the soffit/eave when it approaches the building. The soffit/eave is lower than 12’-0”. Visit the site and provide a proposed detail to address this issue. Explain in a narrative and include a detail showing how you intend to frame and secure the fence to the building when it drops under the soffit/eave.
Notes:
