Commercial and Institutional Building Construction

NAICS 236220 · Construction of Buildings · SBA size standard: $45 million average annual receipts

Commercial and institutional building construction firms prepare bids from drawings and specifications, secure permits and contracts, then manage phased construction with subcontractors, material deliveries, inspections and change orders for projects such as offices, schools, medical clinics and retail buildings. Specialists turn RFPs into takeoffs and estimates, estimates into signed contracts and baseline schedules, schedules into coordinated subcontractor work and material orders, and track inspections, change orders, safety documentation and closeout paperwork while the project manager and superintendent retain authority over scope, payments, safety and occupancy approvals.

What makes this business different

  • Competitive bidding with detailed quantity takeoffs by CSI division, unit pricing and subcontractor quotes that lock before contract award
  • Sequential permitting: building, grading, mechanical, electrical, plumbing, fire and certificate of occupancy with agency reviews and stamped drawings
  • Long-lead procurement of structural steel, mechanical equipment, curtainwall and millwork with shop drawings, submittals and delivery tied to critical path
  • Subcontractor coordination across trades requiring current insurance certificates, performance bonds, certified payroll, lien waivers and progress payments
  • Critical-path schedules updated weekly with weather impacts, inspection milestones, commissioning and owner-driven changes
  • Change-order documentation with pricing, schedule impact and written approval before any extra work or payment
  • Daily safety and SWPPP logs, quality control reports, inspection sign-offs and final punch-list resolution before substantial completion
  • Project closeout with as-built drawings, warranties, operation and maintenance manuals, training and unconditional lien releases

  3. Solicit subcontractor and supplier bids with bid packages
  4. Assemble estimate with direct costs, general conditions, overhead and markup
