Attachment_E_-_Sleeve-Joint_Reference_Photographs.docx

This is a technical reference document for the SMF Pedestrian Walkway Hub - Flight Paths Public Art Installation project under Sacramento County Department of Airports, procured through a CUPCCAA Informal Bid with Contract No. 41015 scheduled for September 2026. Attachment E provides sleeve-joint reference photographs derived from an artist-furnished 3D-printed mockup to guide the installation of overlapping sleeve joints for the public art installation. The document includes four reference images (IMG_5996.jpeg, IMG_5997.jpeg, IMG_6001.jpeg, and IMG_6002.jpeg) illustrating sleeve geometry, seam configuration, and fastener-hole arrangement. These photographs are explicitly designated as non-scalable and serve illustrative purposes only, with actual installation requirements governed by Section 4-1.03(A), SD-06, supplied hardware specifications, and approved design documents.

The connection requirements mandate strict adherence to prefitted holes and supplied 1/4-inch bolts, with a minimum of three bolts required at each joint and four bolts where four holes are provided. Contractors are prohibited from adding, omitting, enlarging, or relocating holes or substituting hardware without written County direction and required permanent-design and authority-having-jurisdiction approval. The reference photographs are explicitly non-scalable, and all installation work must conform strictly to the approved design documents and specifications, ensuring compliance with regulatory agency permits and applicable regulations.
