Capabilities

General contractors need to know one thing before they hand you a scope: can you actually do the work, on time, at size? Here’s what J&M runs — the equipment, the crews, and the credentials behind every job.

Equipment & Self Perform

In-house
boom-truck crane

Spider cranes, scissor lifts, and

rigging — we self-perform the lifts other shops rent or sub out.

CNC plasma cutting

Press brakes, band saws, and

full fabrication equipment.

We handle and
fabricate structural beams up to 60 ft

With special-order lengths

as a job needs them.

The complete scope,
in-house

Cut steel to erected frame, no outside dependency.

Our Crew

A shop crew plus field crews that split to run multiple jobs, backed by an office team — a project manager, an estimator, and coordinators. This is a company that runs on process, not one person carrying every job.

Credentials

AWS D1.1 and D1.8 welds, with WPS/PQR/WQTRs on file, verified by an independent Certified Welding Inspector.
CSLB #1046894 (C-51 structural steel, C-60 welding).
DIR #1000391312 — registered for prevailing-wage and public-works projects, with certified-payroll experience.
Licensed, bonded, and insured — full general liability, auto, and workers’ comp with a $2M umbrella. Bonding available per project, confirmed through our surety. Certificates of insurance on request.

Why it matters?

When you hand J&M a Division 05 scope, you’re handing it to a shop that fabricates it, sets it with its own cranes, and stands behind the welds — on the schedule you’re holding.
