A useful engineering estimate starts with the work you need—not one flat fee for every project. Size matters, but so do the deliverables, existing conditions and coordination required. PEG’s free engineering cost estimator collects those details so we can provide a preliminary fee range privately by email.
Use the form above for projects in California or Texas. Requesting an estimate is free and does not authorize design work. The final scope, fee and schedule are confirmed in a separate proposal.
A structural-only ADU quote is different from a full residential design package. Tell us whether you need structural calculations and review of drawings prepared by others, or PEG’s structural drawings and calculations. Include the total covered area and whether the project is detached, attached, a conversion or an addition.
For a home, separate the living area, garage and covered porches when you can. For a wall, beam or foundation modification, describe the affected area and known spans or dimensions. Existing-building work may require information that a new detached structure does not.
See the California Avenue garage-attached ADU project for one example of the kinds of projects we support. Its scope is not a price template for your property.
Grading and drainage fees depend on the area being improved and the site work involved. Building square footage alone does not describe a grading project. Share the approximate lot area or grading limits, proposed improvements, known slopes and drainage concerns.
Tell us if you already have a topographic survey, soils report or agency comments. Identify wet utilities, retaining walls or other requested improvements separately. A survey, grading plan and utility design are different services; the estimate should make their boundaries clear.
A traffic control plan, signing and striping design, signal design and traffic study are different assignments. Describe what the reviewing agency requested, the roadway limits, affected intersections or signals, and any construction phases.
Traffic work is sized by the actual roadway or study scope—not building floor area alone. Share available base plans, traffic data and agency comments. Field crews, traffic-control equipment and installation costs are not the same as engineering fees.
You do not need every answer to get started. If something needs clarification, we will ask. You can send plans and photographs by replying to our email instead of uploading them publicly.
No. This estimates PEG’s engineering and design fees, not the total cost to build. Permit and agency fees, construction costs and outside services are separate unless expressly included.
No. Your preliminary range is sent directly by email with the proposed scope and assumptions. We do not publish a rate sheet or display your quote on the website.
Supported scopes with enough information can receive an automatically prepared ballpark. Other requests need PEG’s review or clarification before a range is provided. This is not an instant-price promise for every project.
Yes. Reply to the email to discuss priorities, deliverables and possible scope adjustments. The ballpark starts the conversation; it is not a final proposal or authorization to begin work.
PEG includes normal plan-check responses related to the agreed original scope without limiting the number of rounds. Changes to the project or additional services outside that scope may change the fee.
Yes. Choose Español as your preferred email language in the form. You can describe your project in Spanish.
