What Are Conceptual & Preliminary Estimates?

Conceptual and preliminary estimates are prepared during the early stages of a construction project when design information is limited. Rather than relying on fully developed construction documents, these estimates use conceptual drawings, square-foot pricing, historical cost data, building systems, and market trends to forecast the anticipated cost of construction.

These estimates provide owners and project teams with a financial roadmap that guides budgeting, design development, financing, and project feasibility before significant time and resources are invested.

When Do You Need a Preliminary Estimate?

Preliminary estimating is ideal when:

  • Concept drawings are available
  • Construction documents are incomplete
  • Project feasibility needs evaluation
  • Financing or investment approval is required
  • Design alternatives are being compared
  • Budget validation is needed before design development
  • Land acquisition decisions depend on projected construction costs
  • Owners require an initial construction budget

Types of Preliminary Estimates We Prepare

We provide several levels of conceptual estimating based on your project's stage of development.

Rough Order of Magnitude (ROM)

Prepared during the earliest planning phase, ROM estimates provide an initial cost range based on limited project information, helping owners evaluate feasibility and investment potential.

Conceptual Estimates

Conceptual estimates use preliminary layouts, project scope, historical cost data, and square-foot pricing to establish an initial construction budget before detailed design begins.

Budget Estimates

Budget estimates provide a more refined cost projection using schematic drawings, preliminary specifications, and major building systems to support financing, planning, and design decisions.

Definitive Estimates

As design progresses, we prepare detailed estimates using developed drawings, quantity takeoffs, and trade-specific pricing to improve budgeting accuracy and prepare projects for bidding.

What's Included in Our Preliminary Estimates?

Each estimate is tailored to the available project information and typically includes:

  • Construction Cost Summary & Cost per Square Foot Analysis
  • Major Building System Costs & Material Cost Projections
  • Labor Cost Estimates & Equipment Allowances
  • Trade-by-Trade Cost Breakdown
  • General Conditions & Contingency Allowances
  • Assumptions & Exclusions
  • Budget Summary (Editable Excel & PDF Cost Report)

How Our Preliminary Estimates Help

Our conceptual estimating services help clients:

Evaluate Project Feasibility, Establish Realistic Construction Budgets, Secure Financing & Investment, Compare Design Alternatives, Support Value Engineering, Plan Future Project Phases, Reduce Financial Risk, Improve Cost Control, and Make Faster Development Decisions.

By identifying potential cost impacts early, project teams can make informed decisions before construction documents are finalized.

Our Estimating Methodology

Our conceptual estimates combine engineering judgment with current California construction market data.

We develop each estimate using:

Cost Data & Pricing

Historical Project Cost Data, Square Foot & Unit Cost Analysis, California Labor Rates, Current Material Pricing, Supplier Quotations, and RSMeans Cost Data.

Project Factors

Regional Construction Cost Indexes, Building Type Comparisons, Project Size & Complexity Factors, and Local Code & Permit Considerations.

We prepare conceptual and preliminary estimates for:

  • Residential Developments & Custom Homes
  • Multifamily Housing
  • Commercial Buildings, Office Developments & Retail Centers
  • Mixed-Use & Hospitality Projects
  • Industrial Facilities & Warehouses
  • Educational & Healthcare Facilities
  • Government Projects & Civil Infrastructure
  • Renovations & Additions
