Preconstruction Estimating in Lawton, Oklahoma
Before a number goes to an owner, the drawings have to be read against the site, the market and the permit office. Preconstruction is the stretch of a project when the cost can still be shaped, and in Lawton and Comanche County it is also when most of the surprises can be found cheaply. A clean estimate is not a bid with extra notes. It is a priced set of decisions: what is included, what is excluded, what is allowed for, and what the owner should know before the contract is signed.
We estimate from quantities, not from square-foot averages, wherever the drawings allow it. Early in design, when drawings are thin, we build the number from assemblies and from our own recent costs for similar work, and we state the confidence of each line. As design develops, the number tightens, and the owner sees what changed and why. The aim is to keep a budget alive through design rather than rediscover it at bidding.
This work leads naturally to design-build delivery and construction management at risk, in which preconstruction continues into the contract. It also supports the owner who plans to bid the project to several contractors and wants an independent number first.
How an estimate is built
The process starts with a scope read: we go through the drawings and specifications looking for gaps, conflicts and items the design team may have left to the contractor. Then we take off quantities for the major trades, request pricing from subcontractors and suppliers for the long-lead and high-cost items, and fill the remainder from assemblies. We hold a review meeting with the owner and the design team to confirm assumptions.
A good estimate also carries an honest list of risks. Soil conditions that are not known, utilities whose location has not been confirmed, items the owner will supply, and late design changes each have a cost range. We list them, put a number or an allowance beside each, and discuss who owns the risk. Owners prefer this to a low number that grows through change orders.
Value engineering belongs in this stage too, and it works best when it starts early. We bring alternatives to the design team as questions, not as demands: a different roof system, a revised structural bay, a simpler mechanical layout, a change in finish level. Each comes with a price and a note on what it gives up. The owner and the architect decide, and the design moves on with a record of what was considered and why a choice was made.
What moves cost in this market
Several local items surprise owners. Weather resilience is one: the June 15, 2023 storm brought hail of about 2 inches and larger, and insurance agents estimated that about 40 percent of Lawton's residential structures took roof damage, so roofing specifications and insurer requirements deserve attention in the estimate. Soil and geology is another, since the U.S. Geological Survey's fault database describes a documented fault in Comanche County, and a geotechnical report belongs in the early budget.
Market depth is the third. Lawton is a thin market for some trades, so specialty subcontractors may travel in, and we price mobilization where it applies. We also watch public work. The city approved a first-phase road contract of $4,982,600.16 in May 2024, with the work phased to keep the road open, which shows how much road and utility work competes for the same crews and materials. Our site development and utilities pricing reflects the same market.
Estimating the permit
Permit requirements have a cost. The City of Lawton's required-documentation checklist is mandatory for a permit, and a complete building plan means a comprehensive set of construction drawings and specifications with the mechanical and electrical plans, dimensions, a floor plan, a site plan and the scope documents. If the design team has not produced those, the estimate should say who will, and when.
Oklahoma's Construction Industries Board states that general contractors are not currently required to hold a state license for general contracting, though trade licenses are required for licensed trade work and local rules may apply. The City of Lawton licenses contractors in building, electrical, plumbing, mechanical and sign categories. We carry license and permit fees for the trades in the estimate and list who pulls each permit. For more on the process, see permitting and entitlements.
A schedule inside the estimate
An estimate without a schedule is incomplete, since time carries cost: general conditions, equipment rental, escalation and financing. We build a preliminary schedule during preconstruction that shows design milestones, permit review, long-lead orders, site mobilization and the sequence of construction. The owner can test it against a target opening date and see which items control the finish.
Long-lead items are priced and scheduled separately. Switchgear, roofing systems, windows, elevators and specialty equipment can take months, and prices change while they wait. We recommend which items to release early and show the cost and design risk of doing so. Our long-lead procurement page describes the process.
Escalation is handled openly. If design will run for months before bidding, we carry a stated allowance for price movement in the major trades and report what the market is doing at each update. Owners who see that history can decide whether to buy out materials early, hold a contingency or accept a later start. We would rather show a range and its reasons than a single number that cannot survive the next supplier quote.
Where estimating leads next
Preconstruction feeds directly into tilt-wall and warehouse decisions for industrial owners, where the choice of structural system is often a pure cost-and-schedule question.
Public agencies and developers use the same estimating discipline. See government and public sector for procurement-sensitive work and commercial real estate developers for pro forma support.

Common Questions
How accurate can an early estimate be?
It depends on the drawings. With only a program and a site, expect a range and a list of assumptions. As design develops, the range narrows. We state the confidence of each number and update it at each design milestone.
Do you charge for preconstruction?
Terms vary by project. Some owners engage us for a defined preconstruction scope under a separate agreement, and others fold it into a design-build or construction management contract. We explain the options before any commitment.
What do you need to begin?
The site address, building type and size, a target budget and schedule, and any drawings. If there is a geotechnical report or survey, include it. We tell you what else we need.
Can you estimate a project that someone else designed?
Yes. We read the set, list the gaps and price it as drawn, with questions flagged. That is a common request from owners who plan to bid the project.
How do you handle items that are not yet designed?
We carry allowances and list them clearly, with the basis for each number. When design catches up, the allowance is replaced with a real price and the difference is reported.
