About this file
This is a roof framing plan prepared by Brown & Kubican, PSC, for the Commonwealth of Kentucky's Department for Facilities Management, Division of Engineering, for the Professional Services Classroom Center at Gateway Urban Campus located at 438-440 Scott Street in Covington, Kentucky. The plan details structural modifications and new construction related to roof framing systems, including the installation of new 2x12 wood rafters at 24-inch on-center spacing, new APA-rated roof sheathing overlays, steel reinforcement channels for existing wood girders, new steel beam installations with specified load capacities ranging from 200 to 3,000 pounds per reaction point, and associated structural connections using Simpson metal connectors. The project involves coordination between existing structural elements and new installations, including roof hatch modifications, mechanical unit support framing, and masonry wall reinforcement with channel bearing members. The drawing is dated December 18, 2015, and is approved for program concept only, scaled at 1/4 inch equals 1 foot.
The plan emphasizes field verification requirements, including contractor confirmation of all dimensions and existing wood column positions prior to steel shop drawing submission. Critical construction notes specify bearing requirements of two inches minimum on masonry walls, diagonal notching requirements for new members bearing on existing girders, firecut specifications at wall ends, and tight grouting of bearing pockets. Installation details include Simpson LTT19 rafter ties at six-foot maximum on-center spacing with adhesive anchors, Simpson LUS metal connectors for rafter and header connections, and 16-penny nails at 18-inch on-center spacing for sheathing attachment. The document requires contractor compliance with architectural and mechanical drawings for roofing systems, mechanical unit installation, and curb construction, with existing roofing systems to be removed as specified in accompanying demolition drawings.
