Vendor pricing verification: Our estimates utilize real-time price sheets from local concrete batch plants, steel distributors, lumber yards, and specialty vendors active in DeKalb County.

Inspection and jobsite logistics: We model general condition costs—such as site fencing, traffic management, and field supervision—specifically calibrated to municipal requirements across Decatur, Brookhaven, Dunwoody.

Technical Standards & Documentation Audits

We structure all quantity takeoffs under Design-Build Progressive Scope (CSI 00–33) using measurement principles from Design-Build Institute of America (DBIA) progressive estimating standards and Dynamic variance tracking against the initial conceptual GMP baseline cost model. Line items reflect local code criteria defined by DeKalb County Department of Planning and Sustainability building codes, strict stormwater detention requirements, and watershed protection buffer zones.

Assembly-level modeling: We decompose design build estimating services into discrete measurable elements such as GMP Cost Models, Design Evolution Logs, along with Allowance Registers, Design Contingency Schedules, Fast-Track Early Release Packages. Scrap factors are applied transparently.

Sheet verification: Our estimators cross-examine Iterative architectural and engineering drawings (30% SD, 60% DD, 90% CD, GMP packages); Owner Project Requirements (OPR), Basis of Design narratives, and performance specifications to eliminate dimensional errors, uncoordinated MEP penetrations, and structural conflicts prior to bid day.

Installation dynamics: Factoring in fast-track construction phasing allowances (early grading and foundation release packages prior to full architectural permit release)., our estimators calibrate crew sizes and daily output rates to regional Georgia benchmarks.

Building Codes, Soils & Environmental Factors

Municipal Codes & Regulatory Oversight: DeKalb County Department of Planning and Sustainability building codes, strict stormwater detention requirements, and watershed protection buffer zones.
