Mastering OGS Estimating Standards for Public Construction Bids

The New York State Office of General Services (OGS) plays a pivotal role in regulating public construction projects across the state, including many in New York City. For estimators, contractors, and consultants, understanding OGS’s guidelines and cost structures is essential when preparing bids for public works projects.
At True Bid Data, we specialize in preparing compliant, accurate, and streamlined estimates for government-funded projects by aligning them with OGS frameworks—ensuring you meet every technical and procedural requirement.

What is OGS in Construction Estimating?

The OGS manages construction, rehabilitation, and facility upgrades for a wide variety of New York state properties, including courthouses, schools, health facilities, and administrative buildings. Estimators must ensure their takeoffs and pricing structures reflect OGS’s standardized estimating protocols.
These include:

  • NYS prevailing wage compliance
  • Standardized CSI division formatting
  • Use of unit price estimating
  • Budget adherence across phases
  • Strict documentation and backup requirements

Why OGS Matters in New York City Estimating

Many New York City projects—particularly education, healthcare, and public safety facilities—are funded or managed through the OGS framework. These projects require detailed takeoff breakdowns, clear material cost breakdowns, and precise unit labor analysis.
Whether you’re bidding on roofing, mechanical systems, or foundation works, applying OGS standards ensures that your submission is both competitive and compliant.

OGS Estimating Structure: Key Elements

Detailed CSI Division Takeoff

OGS estimates are structured by CSI division—not just for organizing trades, but to ensure budget transparency. From Division 3 Concrete to Division 26 Electrical, each scope must be separated for review.

Accurate Quantity Takeoffs

Estimates must reflect field-verified quantities or validated drawings. Whether you’re preparing a plumbing takeoff, drywall takeoff, or masonry estimating, accuracy in drawings takeoff is non-negotiable.

Prevailing Wage and Labor Costs

Estimates must include prevailing wage rates, which vary across counties. In New York City, these rates can significantly impact your bid competitiveness if miscalculated.

General Conditions and Prelims

OGS projects require a defined allocation of general conditions, prelims, and overhead costs, including security, logistics, insurances, and temporary facilities.

Vendor and Subcontractor Cost Integration

Your bid must include material cost breakdowns and supplier quotes—especially on items like HVAC estimating, steel quantities, or specialty joinery.

Our team helps with cost forecasting, scheduling implications, and phased budgeting for multi-year OGS projects in New York City and beyond.

Example: OGS Roof & Window Replacement

Consider a bid for an OGS-funded project replacing roofs and windows at a state health facility. The scope might include:

  • Demolition takeoff of existing envelope
  • Drywall and insulation estimates
  • Window units and flashing systems
  • Steel lintels
  • Labor costs for roof membrane installation
  • General conditions for scaffolding, waste removal, and weather protection

Each component must be listed under its respective CSI code, priced using OGS methodology, and supported by material and labor analysis. At True Bid Data, we handle all of this under one roof—on time, every time.
