Looking for a civil engineer in Utah who actually returns calls and gets your project approved? Ludlow Engineering has handled civil engineering across Utah since 1975 — from single-lot residential site plans on the Wasatch Front to commercial subdivisions in central Utah and water/sewer engineering for small rural towns. Our in-house team of licensed Professional Engineers (PE) and Professional Land Surveyors (PLS) works under one roof, which means your survey, your engineering, and your stamped drawings stay coordinated from quote to construction. Call (435) 623-0897 for a same-week quote, or request a quote online.
Most Utah firms hand the survey to one company and the engineering to another. We do both — which means fewer handoffs, faster turnaround, and no finger-pointing when something needs to change.
What Civil Engineering Covers in Utah
Civil engineering is the discipline that turns a raw parcel of Utah land into a buildable, permittable, code-compliant project. Where a land surveyor establishes where things are, a civil engineer designs what goes there and how it works — grading, drainage, utilities, access, stormwater, and the engineered drawings that the city or county will actually accept on a building-permit application.
In Utah, that work has its own flavor. Wasatch Front jurisdictions like Salt Lake County, Utah County, and Davis County have detailed plan-review processes and specific stormwater requirements. Rural counties — Sanpete, Sevier, Juab, Millard — have their own quirks around well proofs, septic systems, and water rights. We've worked in every one of them since 1975, and we know which department gets you to "approved" the fastest.
Civil Engineering Services We Provide in Utah
Our civil engineering work covers the full project lifecycle — from site feasibility through final construction observation. The list below is what we do most often, but if you don't see your project type, call us. Forty-five years in business means we've probably done one before.

Whether you're platting a 100-lot subdivision or threading a duplex onto a constrained Wasatch Front infill lot, we deliver engineering drawings that get approved on the first review. Our team has the depth to handle every part of a development from due-diligence through final plat — and the discipline to keep your contractor moving once construction starts.
- Drawings accepted by every Utah jurisdiction we work in
- One contract for engineering + surveying + drafting
- Same-week response on quote requests
- Plan-review comments addressed in days, not weeks
Civil Engineering for Private Homeowners
You don't have to be a developer to need a civil engineer. We work with homeowners on permit-required site plans for additions, shop buildings, and accessory dwellings; on grading and drainage for problem lots; on septic and well siting for rural Utah parcels; and on FHA foundation certifications for manufactured homes.
Our "little guy" philosophy is real. A homeowner with a one-lot project gets the same Professional Engineer working on their drawings as a developer with a 50-lot subdivision.

- Fixed-fee quotes — no surprise change orders mid-project
- Same Professional Engineer on your project from start to finish
- Same-week quote response
- "Little guy" philosophy — small projects get the same care as big ones
Typical Alternative
- Surveying subcontracted to a separate firm
- Limited rural Utah project experience
- Hourly billing that creeps with every revision
- Project handed across multiple engineers
- Slow response on quotes and questions
- Small projects deprioritized or declined
Our Civil Engineering Process
Every Ludlow project follows the same basic workflow. We'll walk you through it on the first call so you know exactly what's coming next.
Site Assessment & Quote
You call or email; we review your parcel, deed, and project goals; we send a fixed-fee proposal with timeline and deliverables.
Survey & Site Investigation
Our field crew completes the boundary and topographic survey. If utilities, soils, or wetlands are in question, we coordinate those too.
Engineering Design
Our PE engineers design the site plan, grading, drainage, utilities, and roadway access. You review at 60% and 90% before final submittal.
Plan-Check & Approval
We submit to the jurisdiction, address review comments, and shepherd the drawings through to a building permit or recorded plat.
Construction Support & As-Builts
Construction staking, plan revisions in the field, RFIs, and final as-built drawings to close out the project for the owner and lender.
We are homebuilders and have used Ludlow Engineering throughout the state of Utah to do the layout of all of our houses. They are prompt, professional, and thorough. Enjoy working with them.

Frequently Asked Questions
What does a civil engineer do for a Utah project?
A civil engineer designs and stamps the parts of your project that go around (and underneath) the building — grading, drainage, utilities, parking, access, and the site plan as a whole. In Utah, a stamped civil drawing set is what the city or county requires before issuing a building permit on any project beyond a simple residential addition. We also handle subdivisions, stormwater, water/sewer engineering, and floodplain work.
How much does civil engineering cost in Utah?
Residential site plans typically run $2,500–$7,500. Small commercial site plans run $5,000–$15,000. Subdivisions are quoted by lot count and complexity, generally starting at $15,000 for a small 2–10 lot project. House plan engineering for a custom home runs $1,800–$5,500. See our pricing table above for more, or call (435) 623-0897 for a fixed-fee quote.
Do I need a civil engineer or just a land surveyor?
A land surveyor establishes where the boundaries, elevations, and existing features are. A civil engineer takes that survey and designs what you're going to build — grading, drainage, utilities, access — and stamps the drawings so the jurisdiction will issue a permit. Most projects need both. Since we provide both in-house, you only need one contract and one point of contact.
How long does civil engineering take in Utah?
A residential site plan from contract to approved drawings typically takes 6–10 weeks (3–5 weeks of design plus the jurisdiction's plan review). Small commercial site plans run 8–14 weeks. Subdivisions take 3–9 months depending on size, jurisdiction, and whether environmental or water-rights issues arise. Plan-review backlogs along the Wasatch Front can extend timelines — we'll give you a realistic schedule up front.
What types of civil engineering projects does Ludlow Engineering handle?
We work on residential, commercial, industrial, and public-infrastructure projects across Utah. The most common work is site plans, subdivisions, grading and drainage, stormwater design, water and sewer engineering, floodplain analysis, FHA foundation certifications, and house plan engineering. We've been doing this in Utah since 1975, so most project types we've handled before.
Are civil engineers required to be licensed in Utah?
Yes. Any stamped civil engineering drawing in Utah must be sealed by a Professional Engineer (PE) licensed by the Utah Division of Occupational and Professional Licensing (DOPL). All of our civil engineering deliverables are stamped by a Utah-licensed PE. You can verify any engineer's license on the DOPL website.
Do you serve clients outside central Utah?
Yes. Our office is in Nephi but we regularly work across the entire state — from Salt Lake County and the Wasatch Front south to Washington County, and east through Carbon and Wasatch counties. Travel costs may be reflected in the quote for distant locations, but we don't decline projects based on distance.
Can you handle both the civil engineering and the surveying for my project?
Yes — and that's our main point of difference from most Utah firms. Our in-house team includes both Professional Engineers and Professional Land Surveyors. You sign one contract, work with one project manager, and never have to coordinate between two separate companies. Most clients save 10–25% in total project cost by bundling.
