Dail-Water-Stop-Tie-In-Model.pdf

This is a technical drawing specification document for asphaltic roofing systems, specifically detailing daily waterstop and tie-in procedures for roof construction or renovation projects. The drawing, designated DWG NO. 30A and titled "Daily Waterstop/Tie-In," provides architectural guidance for contractors performing roofing work. The specification outlines the proper methodology for creating temporary tie-ins between existing and new roof systems, ensuring waterproofing integrity during multi-day construction phases. Key technical requirements include the application of mastic seal at edges with compatible reinforcing mesh, extension of tie-in sheets a minimum of six inches onto both existing and new surfaces, and the use of compatible mastic between existing and new insulation layers. The document mandates removal of temporary tie-in materials and insulation fillers before commencing subsequent work phases.

The drawing is presented at a not-to-scale (NTS) format and appears to be part of a 2023 sheet set model, suggesting it is a standard specification document for roofing projects within a given jurisdiction or agency. No pricing information, contract terms, set-asides, funding sources, or other procurement-specific details are provided in this technical specification document. The drawing serves as an engineering standard to ensure proper installation procedures and material compatibility during roof system construction or renovation work.
