Why Conceptual Cost Estimates Matter

Early project decisions are often made before a complete set of construction documents exists.

At this stage, there may be limited information about assemblies, finishes, systems, quantities, and specifications. A conceptual estimate uses the available project information to develop a reasonable preliminary cost framework without presenting early assumptions as final construction pricing.

Building a Budget From the Information Available

We can develop conceptual costs from available project information such as:

  • Project descriptions
  • Preliminary drawings
  • Concept plans
  • Site information
  • Building areas
  • Preliminary floor plans
  • Project specifications
  • Design narratives
  • Preliminary material selections
  • Owner requirements
  • Existing estimates
  • Comparable project information

The level of detail in the estimate is matched to the level of design information available.

What Is Included in a Conceptual Cost Estimate

  • Preliminary project scope review
  • Building area analysis
  • Preliminary quantity development
  • CSI-based cost organization
  • Material cost allowances
  • Labor cost allowances
  • Equipment allowances where applicable
  • General conditions
  • Design-stage assumptions
  • Building system allowances
  • Sitework allowances
  • MEP allowances
  • Finish allowances
  • Construction cost summary
  • Cost per square foot where appropriate
  • Alternates where applicable
  • Assumptions
  • Exclusions
  • Budget notes
  • Editable Excel estimate

Conceptual Estimating by Building Type

Conceptual construction estimates can be developed for:

  • Commercial buildings
  • Office buildings
  • Retail
  • Restaurants
  • Multifamily
  • Apartments
  • Single-family residential
  • Industrial facilities
  • Warehouses
  • Institutional buildings
  • Hospitality
  • Tenant improvements
  • Renovations
  • Additions

Early-Stage Construction Budgeting

A conceptual estimate can help project stakeholders evaluate whether an initial project idea fits within an anticipated construction budget.

As design develops, the preliminary budget can be refined with additional drawings, specifications, quantities, and material selections.

Conceptual Construction Estimating for California

We provide conceptual cost estimating services throughout California for owners, developers, architects, contractors, and other construction professionals.

California project budgets can be organized around the available project location, building type, scope, and level of design information.

Conceptual vs. Detailed Estimating

A conceptual estimate is developed when project information is still limited.

A detailed construction estimate is normally prepared after more complete drawings, specifications, quantities, and material selections are available.

The purpose of conceptual estimating is therefore to establish an informed preliminary budget rather than replace a final bid estimate.
