Technical Estimating
Walkthroughs.
Sample estimating scenarios based on common commercial construction patterns. Each walkthrough demonstrates our forensic methodology for scope validation, code compliance, and value engineering.
Electrical Estimate — 42-Story Commercial Tower
Feeder schedule NEC compliance audit, busway vs. wire-and-conduit VE analysis, and cable tray routing conflict resolution on a 680,000 SF Chicago high-rise.
HVAC Estimate — 280-Bed OSHPD Hospital
ASHRAE 170 ventilation compliance matrix, HEPA filtration upgrade analysis, ICRA Level IV protocols, and NFPA 99 medical gas piping quantification.
Plumbing Takeoff — 1,200-Student K-12 Campus
IPC fixture unit analysis against TFER food service rules, ADA compliance validation, grease interceptor sizing, and Texas prevailing wage labor burdens.
Process Piping Estimate — Gulf Coast Refinery Turnaround
P&ID-based stainless steel quantification, ASME B31.3 weld classification, 100% RT testing pricing, and compressed-schedule labor inefficiency factors.
Concrete Estimate — Post-Tension Parking Garage
PT tendon quantification, flying form vs. shoring tradeoff analysis, ACI 318 rebar lap splice waste, and FBC HVHZ mechanical coupler scope.
The VFD Disconnect: Div 23 vs. Div 26 Conflict
How a conflicting specification between HVAC and Electrical plans almost cost the GC $85,000 during the GMP validation phase of a school project.
The Winter Heating Claim — Cold Weather Concrete
Proving concrete yield overrun factors, subgrade insulation offsets, and cold weather chemistry costs under ACI 306R in Syracuse, NY.
