Construction Cost Estimating Services for Accurate Project Budgeting and Bid Preparation

A cost estimate is a calculation of the probable cost of a project based on quantity takeoffs, unit pricing, labor rates, and material costs. A bid is a formal offer submitted to an owner or general contractor that includes the estimate plus profit margin, overhead, and risk contingency. The estimate is the foundation of the bid, but the bid reflects the contractor's business strategy including market conditions, competition, and risk appetite.

Labor costs are determined by multiplying the estimated labor hours for each work item by the applicable hourly labor rate. We use RSMeans productivity data for labor hours by trade and activity, adjusted for project conditions such as height, density, and complexity. Hourly rates are based on current wage data for each trade and geographic location including base wages, fringe benefits, workers compensation, and payroll burdens specific to each state and county.

Regional cost factors adjust national average material prices and labor rates to reflect the specific cost environment of a project location. Factors account for differences in material availability, transportation distances, local labor wage rates, union versus open shop prevalence, workers compensation rates, and local market conditions. We apply RSMeans city cost indexes and location factors to adjust every line item in the estimate to the correct cost basis for the project zip code.

Preliminary cost estimates prepared during the conceptual or schematic design phase typically have an accuracy range of plus or minus 20 to 30 percent. As design progresses and more detail becomes available, estimates become more accurate. Budget estimates at the design development phase achieve plus or minus 10 to 15 percent. Final detailed estimates based on complete construction documents achieve plus or minus 3 to 5 percent. Every preliminary estimate is clearly marked with its expected accuracy range.

RSMeans is a comprehensive construction cost database published by Gordian that provides current unit prices for thousands of construction materials, labor rates, and equipment costs. It includes productivity data, crew compositions, city cost indexes, and detailed cost breakdowns for every building system. We use RSMeans Online to apply current national average pricing adjusted by regional cost factors to every line item in our estimates, ensuring consistent and defensible cost data.

Escalation accounts for the expected increase in construction costs over the duration of a project. We apply escalation factors based on historical construction cost indexes and current market forecasts published by RSMeans and the Bureau of Labor Statistics. For multi-year projects, we escalate material, labor, and equipment costs separately by year of expenditure. Our escalation calculations are clearly documented showing the base cost, escalation rate, and adjusted total for each phase of the project.

Cost estimates are delivered in Microsoft Excel format organized by CSI MasterFormat divisions with line items showing quantities, unit costs, extended costs, and adjustments. Each estimate includes a cost summary, detailed breakdown by division, material and labor separation, equipment costs, subcontractor quotes, general conditions, overhead and profit, and contingency. Estimates are formatted for direct use in bid preparation, budget development, value engineering analysis, and owner reporting.

Yes. We provide cost validation services where our estimators review existing cost estimates for accuracy, completeness, and market alignment. Our validation process includes checking quantities against drawings, verifying unit pricing against current market data, confirming labor productivity assumptions, and comparing the estimate against historical project costs for similar project types. We deliver a validation report identifying potential risks, omissions, and opportunities for cost optimization.

Yes. We provide cost estimating services for design-build, integrated project delivery, and early contractor involvement project delivery methods. For design-build projects we provide progressive estimates at each design milestone starting from schematic level through design development to detailed construction documents. Our phased estimating approach allows design-build teams to make informed decisions about system selection, material choices, and constructability throughout the design process.

Value engineering is a systematic process of reviewing building systems, materials, and construction methods to achieve the required function at the lowest total cost without sacrificing quality or performance. We support value engineering by providing cost comparison analyses for alternative materials, systems, and design options. For each VE alternative we present the cost difference, impact on schedule, effect on lifecycle costs, and any performance trade-offs to enable informed decision making.
