Who we are

A general contractor built for public work.

Grading equipment working on an active construction site beside a building under construction

MPX Construction LLC holds a California Class B General Building license and is registered with the Department of Industrial Relations to bid and perform public works. We self-perform general contracting, scheduling and project management.

Rather than carrying idle trade crews, we assemble a competitively bid team of licensed, insured subcontractors for every scope on every job. That keeps our overhead lean and our numbers sharp — while giving the awarding agency the single point of accountability it expects from a general contractor.

Leadership

Led by a public works engineer.

Most contractors learn how agencies award work from the outside. MPX's owner spent nine years on the inside of one.

MPX Construction is a woman-owned firm. Ana Marilia Ramos holds a Bachelor of Science in Civil Engineering and worked more than a decade in public infrastructure before founding the company — including two years as Head of the Department of Public Works for a provincial government authority, on the awarding side of public contracts.

That career covered the full lifecycle this company now bids into: writing and running public tender programs, evaluating contractor submissions, inspecting work in progress, and closing out contracts for hospitals, schools, courts and highways.

How we work

Every bid runs the same six steps.

The discipline is the product. A repeatable procurement process is what lets a lean contractor price aggressively without carrying risk into the schedule.

Step 01

Scope review & takeoff

We read the full solicitation, drawings and specifications, and build a quantity takeoff before pricing anything.

Step 02

Trade package breakdown

The job is divided into discrete trade scopes so nothing falls between two subcontractors at buyout.

Step 03

Minimum five quotes per trade

Every trade goes out to at least five qualified subcontractors, prioritizing those nearest the site to hold down mobilization and haul costs.

Step 04

License & insurance verification

Each quoting subcontractor is checked against CSLB licensing and current insurance before their number enters the bid.

Step 05

Bid assembly & submission

Scopes are levelled, gaps closed, and the proposal submitted complete with all required forms and bonds.

Step 06

Construction & closeout

Schedule, safety and quality managed in the field through punch list, final inspection and closeout documentation.

Structure

Small by design, accountable by structure.

MPX Construction is owner-operated out of San Diego. The person who reviews the solicitation is the person who assembles the bid and answers the phone during construction — there is no layer between the agency and the decision-maker.

That structure suits the work we pursue: projects where responsiveness and a clean paper trail matter more than the size of the letterhead.

Ana Marilia Ramos

Oversees estimating, subcontractor procurement and project delivery for every MPX contract.
