Preliminary Estimating Services for Smart Early Decisions

Accuracy depends on how much project information is available. A rough order of magnitude estimate typically carries an accuracy range of -25% to +50%. As more design information becomes available, that range tightens significantly. A well-prepared preliminary cost estimate based on schematic drawings can come within ±15 to 20%. We're upfront about accuracy expectations on every estimate we deliver.

A preliminary cost estimate is produced early in the project lifecycle, often before detailed drawings exist, using benchmarks, historical data, and high-level scope information. A detailed estimate comes later, based on complete construction documents, and breaks costs down to the individual line-item level. Preliminary estimates inform decisions. Detailed estimates lock in pricing.

We can work with whatever you have. At a minimum, project type, approximate square footage, location, and a general scope description are enough to produce a meaningful preliminary project budget. Sketch drawings or a schematic design improve accuracy further. We'll let you know upfront if we need anything additional.

Yes, and it's one of our core areas. Preliminary estimating services for federal work require documentation, structure, and defensibility that go beyond a standard ballpark. We understand what federal agencies expect from early-stage cost estimates, and we build every federal submission to that standard.

Our estimates include a project cost summary by major division, material and labor breakdowns, site work and general conditions allowances, contingency recommendations, and a full summary of the assumptions and methodology used. Federal estimates also include supporting cost narratives as required.

Absolutely, that's exactly what early-stage construction estimating is designed for. We regularly work from 30%, 60%, or 90% drawing sets, schematic designs, and design development packages. We build around what's defined and apply documented assumptions for what isn't.

For most mid-size commercial or federal projects, we deliver within 24 to 48 hours of receiving your project information. For larger or more complex scopes, we give you a specific timeline upfront so there are no surprises on timing.

A rough order of magnitude estimate is the most high-level form of preliminary estimating used when a project is conceptual, and design information is minimal. It's ideal for go/no-go decisions, early budget discussions with investors, and feasibility checks before committing to design fees. Think of it as the first honest financial reality check on a project idea.

Conceptual cost estimating goes a step beyond a ROM estimate. It's done when schematic drawings or a design brief are available and produces a structured cost breakdown by major building system or CSI division. It's the most commonly used form of preliminary estimating services during the early design phase and is detailed enough to support owner budget decisions and funding applications.

Not exactly. A preliminary project budget is an early planning tool based on limited design information. A construction budget is a finalized cost plan developed after complete drawings are done and contractor pricing has been obtained. The preliminary project budget is the foundation on which the construction budget is eventually built, which is why getting it right at the start matters so much.

Yes. We provide preliminary estimating services in the USA and Canada across all major markets, including commercial, federal, institutional, industrial, healthcare, and residential. Location-specific cost data is factored into every estimate, so your numbers reflect actual market conditions where your project is being built.

Yes, and this is one of the most common reasons clients come to us. Lenders, investors, and funding agencies frequently require a preliminary cost estimate as part of the project approval process. We produce estimates that are clearly structured, documented, and supported by methodology notes, ready for financing conversations and investment presentations.

Scope changes are normal at the early stage. If your project evolves significantly after we deliver an initial estimate, we will revise and update the preliminary cost estimate to reflect the new scope. Accurate numbers that match your current plan always beat an outdated estimate, driving your decisions.

Just share your project details, such as drawings, scope narrative, square footage, or whatever you have. We review the information, confirm the estimated scope, and get to work immediately. No lengthy intake process, no delays, just fast, accurate preliminary construction estimating services when you need them.
