M&M Engineering & Construction is a self-performing heavy civil and infrastructure contractor — delivering roadway, structures, grading, and public works with engineering precision and field discipline.
We pair engineering rigor with the heavy equipment and crews to put the work in the ground — one accountable team from estimate to closeout.
M&M Engineering & Construction, Inc. is a heavy civil contractor headquartered in Irvine, California. We build and rehabilitate the systems that move people and water through Southern California — highways and arterials, bridges and structures, grading and earthwork, storm drain and underground utilities, and the concrete that holds it all together.
Because we self-perform the core scopes, schedule, cost, and quality stay under one roof. That control is how we hold a budget, protect a critical-path date, and hand back work that lasts.
A full heavy civil scope under one contractor — engineered, scheduled, and built by our own crews and equipment.
Grading, aggregate base, asphalt and PCC paving, widening, and rehabilitation for state highways and municipal arterials.
Cast-in-place concrete, retaining and sound walls, abutments, and drainage structures built to DOT specification.
Mass excavation, site preparation, balancing, and subgrade — moving dirt accurately and at volume.
Storm drain systems, pipelines, wet and dry utilities, and inlet and manhole structures.
Curb and gutter, sidewalk, cross gutters, barrier, and ADA-compliant ramps and improvements.
Traffic signals, highway and street lighting, ITS, signing and striping, and traffic control — backed by C-10 electrical and C-7 low-voltage licensing.
Public and private infrastructure across Southern California — from state transportation programs to private site development.
State and federal highway programs, including Caltrans and regional transportation agencies.
Municipal streets, drainage, and infrastructure improvements for cities and counties.
Airfield paving, taxiways, and heavy civil supporting transit and freight corridors.
Storm drain, channels, and drainage infrastructure for cities, counties, and flood control districts.
The heavy civil disciplines we self-perform — from earthwork and structures to the roadway surface and the systems beneath it.
Safety isn't a binder on a shelf — it's how we plan the work and run the crew. Quality follows the same standard: build it right the first time, document it, and hand back work that holds up under inspection and under load.
From the first takeoff to final closeout, M&M is built around accountable people in every seat — estimating, field, project management, and office — working as one to deliver the job.
Quantity takeoffs, competitive bids, and buyout — pricing the work accurately and building the schedule before we mobilize.
Superintendents, equipment operators, and crews self-performing the work in the field, on schedule and to spec.
Contract administration, RFIs, submittals, change orders, and schedule — keeping the job on track and fully documented.
Accounting, payroll, compliance, and contracts — the back office that keeps crews paid and projects moving.
We're always looking for operators, field leaders, estimators, and project staff who take the work personally. If you build it like your name is on it, we should talk.
