The scopes we take as a sub.
Everything below is work we self-perform. Each one has its own page covering how the job runs, what is included, and what holds it up. If the scope you are pricing is not listed, call and ask.
Structural Steel
C-51The licensed side, and all of it self-performed. Steel that holds a building up, fabricated in the shop, then set and welded on site by the same two people.
Structural steel fabrication
Beams, columns, and frames cut, drilled, and welded up before they reach the site.
How it worksSteel erection
Columns, beams, and headers set, plumbed, and connected.
How it worksMoment frames
Ordinary and special moment frames, set and field welded to the engineer's detail.
How it worksRetrofit and reinforcement
Adding steel to a structure that was not built for the load it carries now.
How it worksField welding
Connections welded on site, ready for special inspection.
How it worksEmbeds, base plates, anchor bolts
Set before the pour so the steel lands where the drawings say.
How it worksOn-site cutting, coping, drilling
When the member showed up an inch long, we fix it in place.
How it worksMobile Welding
The rig lives on the truck. This is the reason a GC keeps a sub who does both: when something has to be cut, fit, and welded today, your schedule does not go and sit in somebody's shop queue.
On-site repair welding
We come to the job, the yard, or the shop. Rig on the truck.
How it worksGates, fences, railings
Guardrail, handrail, gates, and fence, field measured to what is actually built.
How it worksStairs, ladders, catwalks
Stringers, treads, and handrail fabricated and installed.
How it worksTrailer and equipment repair
Cracked frames, broken mounts, busted racks. Back in service same day where we can.
How it worksCustom fabrication
One-off parts, brackets, mounts, and frames built to a measured space.
How it worksThe things people ask.
Short answers. If yours is not here, call (949) 230-3866.
Are you licensed and insured?
Yes. CSLB license #1157116, classification C-51 Structural Steel, current and active. We carry $2,000,000 in general liability, workers' compensation, a $25,000 contractor's bond, and a $100,000 LLC worker bond. Certificate of insurance and W-9 available on request. Additional insured endorsement per your subcontract. You can verify the license yourself at cslb.ca.gov.
Do you work as a subcontractor to general contractors?
Yes, and that is most of the work. We take structural steel scopes as a sub: erection, field welding, fabrication, moment frames, embeds, and misc metals, all self-performed. Send the structural sheets and we will price the scope. The licence, insurance, and bid details an estimator needs are on the page for general contractors.
What areas do you serve?
We are based in San Clemente and most of our work is South Orange County: Dana Point, San Juan Capistrano, Laguna Niguel, Laguna Beach, Aliso Viejo, Mission Viejo, Ladera Ranch, and Rancho Santa Margarita. We travel across the rest of the county for the right job.
Do you do residential moment frames?
Yes, and it is a lot of what we do. A moment frame is the steel that carries a wide opening without a wall in the middle of it. Send the structural sheets and the frame schedule and we will price it.
Can you weld on site, or does everything go to a shop?
On site. The rig is on the truck. Field welding, cutting, coping, and drilling all happen where the steel is, which is what keeps a job moving when a member turns up wrong.
Will your welds pass special inspection?
That is the standard we work to. Our responsible managing employee holds the C-51 qualification, is on the job rather than on the paperwork, and we schedule around the special inspector so the connection is seen while it is still open.
How do I get a price?
Send the plan sheet, or text a photo for the mobile work. For structural scopes the drawings tell us most of what we need. We will tell you when you will have a number rather than guessing at a turnaround.
Do you take small jobs?
Yes. One frame, one dropped beam, or a punch list weld is a normal call. Small structural scopes are the ones most erectors will not mobilize for, and they are normal work here.
OC Mobile Welding LLC holds CSLB C-51 #1157116, C-51 Structural Steel, and carries $2,000,000in general liability and workers’ compensation. That classification covers the structural work. The mobile welding is done by the same licensed and insured company.
