Civil Construction and Site Development
J and J Civil Construction, LLC is a civil construction and site development contractor based at 4190 S Highland Dr Ste 114 in Millcreek, Utah. Our crews move earth, place pipe, pour flatwork, and pave roadways for developers, municipalities, and general contractors across the Wasatch Front. From the first survey stake to the final punch list, we deliver sites that drain right, compact true, and stand ready for vertical construction.
What We Build
Every project we take on moves through the same disciplined sequence, and the same superintendant signs off at each step. There is no handoff gap between the operator cutting the pad and the pipe crew following behind, because they answer to the same office in Millcreek. That continuity is why developers hand us whole phases instead of single scopes.
Below is the full range of civil work we self-perform, from raw acreage to a street that is striped, swept, and ready for occupancy.
Sitework
We clear and grub building pads, strip topsoil, and shape the ground to plan grade with GPS machine control. Cut and fill balances keep haul-off volumes low and compaction counts high. Every lift is tested to the specification of the engineer of record before the next layer goes down. The result is a pad that will not settle, shift, or surprise anyone later.
Utilities
Water, sewer, storm drain, and irrigation lines go in the ground the right way the first time. We trench, bed, lay, and backfill pipe with proper haunching and compaction at every stage. Pressure tests, mandrel pulls, and camera inspections document each line before it is covered. Every corridor we close is mapped, and as-builts are delivered with the package.
Concrete
Footings, stem walls, slabs, curb and gutter, sidewalk, and ADA ramps are formed, poured, and finished by our own crews. We control joints, cure properly, and protect fresh concrete from Utah weather swings. Flatwork is checked for thickness, elevation, and slope so water goes where the design intends. Clean edges and tight tolerances are the standard, not the exception.
Paving
Subgrade proof rolls, aggregate base course, and asphalt lifts are placed to specification and tested along the way. We pave subdivision streets, access roads, and parking fields with attention to line, grade, and ride quality. Joints are sealed, transitions are flush, and striping is coordinated with the marking crew. The finished section reads smooth and drains clean.
Drainage
Detention and retention basins, culverts, catch basins, swales, and outfall structures are built to move storm water without erosion. We grade channels, set inlets to exact rim elevations, and armor outlets where flow concentrates. Hydroseed, riprap, and geotextile protection keep slopes stable through spring runoff. Drainage is engineered once and built to last for decades.
Management
Estimates, budgets, schedules, SWPPP documents, and municipal permits are managed in house from kickoff to closeout. We coordinate geotech, survey, inspections, and utility providers so trades never idle. Owners get weekly progress updates with photos and a clear look at cost to complete. At turnover you receive as-builts, compaction reports, and a warranty package.
The Profile Below Your Project
Before a single wall rises, the ground underneath it has to be built like a structure of its own. Our crews read the geotech report, strip the organics, and rebuild the profile layer by layer: clear and grub the surface, cut and fill to design grade, trench and backfill the utilities, then compact and test until the density numbers hold. The cross-section below is the sequence we follow on every subdivision road, commercial pad, and parking field we take on.
Skipping a lift or rushing a test does not show up on day one. It shows up three winters later as settlement cracks, sagging pavement, and ponding water. We build the profile right the first time because that is the only way we know how to hand over a site.
Typical Engagements
The ledger below lists five project types we deliver on repeat, with the schedule range we would normally quote for each. Numbers shift with weather, review cycles, and utility relocations, but these ranges have held across dozens of builds. Use them as a planning baseline for your pro forma.
Full sitework for a six-lot cul-de-sac: mass grade, utility laterals, curb and gutter, and base course ready for asphalt.
Structural slabs, ramps, and drive aisles for a two-level parking deck, placed in pours sequenced around frame erection.
An aging dry basin regraded and rebuilt with a new outlet control structure, riprap armor, and cleanout access for maintenance crews.
Replacement of a failing sewer main under an active street, with live tie-ins scheduled for overnight windows to keep traffic moving.
A half mile of new residential roadway from subgrade to final lift, including signage, striping, and the closeout punch list.
Timelines reflect typical ranges under normal weather and permitting conditions. Site specifics, contamination, and utility conflicts can move a schedule in either direction, and we flag those risks in writing during estimating.
We build civil work the way an engineer would build it for their own street: tested lifts, documented utilities, and drainage that quietly does its job for fifty years. That standard is why general contractors in the Salt Lake Valley call us before they call anyone else.
Send us your site plans or a short scope description and we will return a line-item estimate with a realistic schedule, usually within five business days. No fee, no obligation, and a real person answers the phone.
