HKS Architects Documentation Hub for Specifiers & Builders

Documentation you can put into a bid set

Every HKS Architects resource package is written for architects of record, construction managers, and specialty subcontractors—not marketing glossaries. We state fire resistance rating (Class A / 1–2 hour assemblies where listed), R-value assumptions (often R-15 to R-28 continuous wall targets), STC ranges (ASTM E90 laboratory data), thermal conductivity notes for insulation layers, air permeability limits, and installation tolerances in the same language as Division 07 and 09 specifications. Packages are versioned by climate zone and substrate family so a cold-climate continuous insulation detail is never mixed with a warm-humid vapor retarder sequence.

Selection trade-off we document openly: natural stone accent cladding can raise perceived value and unique aesthetics, while engineered panel fields usually win on water absorption rate control, embodied carbon tracking, dimensional stability, and schedule certainty. Sustainability-versus-budget is treated the same way—LEED or WELL pathways can add roughly 10–20% to some material lines; we show lifecycle maintenance and recycled content percentage so owners choose a trade-off, not a slogan. Prefabrication versus traditional field build is likewise quantified: factory panels cut waste and labor variability; stick-built zones retain flexibility when geometry changes late.

Domestic versus import panel sourcing appears as a compliance and lead-time matrix (Buy America eligibility and shorter freight versus 20–40% cost deltas on some categories). Competitive framing stays evidence-based: we compare published laboratory STC/fire reports and EPD values, not brand slogans, and we refuse to publish “equivalent” claims when test methods differ.
