I help design teams align assemblies, attachment, and detailing so bids are comparable and buildable. The goal is to reduce RFIs, clarify substitution rules, and ensure spec intent translates to the field.
I review Division 07 roofing sections to ensure spec language aligns with buildable assemblies and reduces substitution confusion. Here's what I typically review:
Need spec language review? Submit a request with your spec section and drawings.
Clear assembly intent reduces bid variation and field confusion. Here are the key factors I help define:
Define wind uplift requirements based on building height, exposure, and local code. Ensure attachment method and fastening pattern meet design criteria.
Clarify deck type (steel, concrete, wood, gypsum) and condition. Attachment method must be compatible with deck substrate.
Define insulation type, thickness, and securement method. Ensure thermal performance aligns with energy code requirements.
Specify mechanical, induction, or adhered attachment. Each has trade-offs in schedule, cost, and performance.
Define enhanced attachment zones at perimeters and corners where wind uplift is highest.
Florida building codes require specific approvals and documentation for commercial roofing systems. Here's what to consider:
Most RFIs and field issues stem from unclear or incomplete details. Here are the typical coordination points:
Clarify who provides edge metal (roofing contractor vs. sheet metal contractor). Define termination details and flashing laps.
Define drain bowl securement, membrane tie-in, and overflow provisions. Clarify sump conditions and slope requirements.
Specify minimum curb height (typically 8" above finished roof). Define cant integration and flashing lap requirements.
Define membrane termination at parapets, including cant strips, flashing, and counterflashing coordination.
Clarify overflow drain requirements, scupper sizing, and emergency drainage paths per code.
Define curb coordination, access walkways, and service clearances for rooftop equipment.
RFIs during construction slow projects and create confusion. Here's a process to reduce them:
Clarify performance requirements, attachment method, and warranty expectations in the spec.
Provide buildable details for edges, penetrations, drains, and transitions in the drawing set.
If alternates are allowed, define acceptable substitutions and performance criteria.
Clarify what can be substituted (products) vs. what cannot (attachment method, warranty structure).
To provide useful spec and detail support, I'll need the following:
