1. Within this scope of work there will be three types of existing signage that the signage contractor will be updating. Examples of each sign type are shown below: a. Building Monument Signage (Quantity of 50 Signs to Upgrade) b. Facility Identity Signage (Quantity of 25 Signs to Upgrade) c. Pedestrian Directional Signage (Quantity of 35 Signs to Upgrade) 2. Material Specifications for Exterior Signage a. Fabrication: Shop fabrication and tolerances shall conform to the standards of the industry. All items shall be shop fabricated so far as practicable. Perform high-quality, professional workmanship. Attach materials with sufficient strength, number and spacing not to fail until materials joined are broken or permanently deformed. Fabricate all work to be truly straight, plumb, level and square and to sizes, shapes and profiles as indicated in this scope of work. i.Shop Assembly: Pre-assemble items in shop to the greatest extent possible to minimize field splicing and assembly. Disassemble units only as necessary for shipping and handling limitations. Clearly mark units for re-assembly and coordinated installation. ii.Welding: All welding procedures shall conform to applicable AWS specifications. All welds shall develop the capacity of members being joined unless specific length or extent is noted in this scope of work. The type of alloy filler metal and electrodes to be that which is recommended by producer of the metal to be welded, and as required for color match, strength and compatibility in the fabricated items. iii.Flatness of Panels: Panels shall show no visual distortion when viewed in installed position. All panel faces shall be of such flatness that when measured, the maximum slope of the surface at point, measured from the nominal plane of the surface, shall not exceed 1.0%. Any panel not meeting these requirements is subject to rejection by SHSU. iv.Wind Loading: Exterior signs shall be designed to withstand wind pressure loadings of 30 psf (146.5 kg/sq. m) on the gross area of the exposed units, acting in all directions or to meet and/or exceed all applicable codes, whichever is greater. The selected signage contractor will be required to have structural elements of exterior signs stamped by an engineer. Standard and approved methods of fabrication will be required by the owner. v.Thermal Movement: Design, fabricate and install component parts to provide for expansion and contraction over a temperature range for the material of 150 degrees Fahrenheit (83.3 degrees Celsius), without buckling, sealant joint failure, glass breakage, undue stress on members or anchors, and other detrimental effects.
