About this file
This Supplemental Instruction document, issued by Mead & Hunt on behalf of Solano County to the contractor Gilbane Building Company, clarifies and consolidates painting and coating requirements for the Justice Center Asset Protection project. The document establishes detailed specifications for painting and coating work across two volumes of construction drawings, including the application of primers, topcoats, and protective finishes to various material substrates such as structural steel, pipes, equipment, concrete, and pavement. The supplemental instruction specifies surface preparation requirements ranging from solvent cleaning to near-white blast cleaning, along with precise dry film thickness (DFT) measurements in mils for each coat application. Work encompasses multiple property locations including addresses on Union Avenue, Clay Street, Delaware Street, and Texas Street, with specific attention to both immersion and non-immersion environments, interior and exterior exposures, and specialized applications such as manhole covers, precast concrete structures, and striping.
The supplemental instruction maintains the original contract sum and contract time with no modifications, indicating this clarification is procedural rather than a change order. The painting and coating schedule references specific material products including epoxoline primers, tneme-zinc coatings, endura-shield topcoats, and tneme-tar formulations, with application methods specified by brush, roller, and spray as appropriate to each surface type and environmental condition. The work is organized into categories designated A-1 through J-1 in Volume 1 and pavement striping specifications in Volume 2, each with corresponding drawing references and material service classifications that align with industry standards such as SSPC (Society for Protective Coatings) specifications for surface preparation and coating quality assurance.
