CIVIL CONTRACTOR MOBILIZATION AND DEMOBILIZATION BILLING.
Mobilization on a civil project is not free. Transporting a dozer, excavator, and support equipment to a job site 40 miles away costs $4,000–$8,000. Setting up temporary facilities, erosion controls, and site infrastructure before a single cubic yard is moved costs another $15,000–$40,000 depending on project size. Demobilization — removing equipment, restoring site access, cleaning up — costs another $3,000–$8,000. None of that is overhead. All of it should be in the SOV as separate line items billed and collected before the work sequence begins.
Most civil contractors absorb mobilization and demobilization into overhead or lump it into the first production phase. Both approaches mean the cost is either never recovered or recovered at the end of a long project when the GC is scrutinizing every line. A dedicated mobilization line item billed at contract start and a demobilization line billed at project completion is the clean, contractually transparent approach that protects your cash and your margin.
MOBILIZATION AND DEMOBILIZATION — WHAT THEY INCLUDE.
Everything Required to Set Up for Production
Equipment transport to site — trucking cost for each piece of equipment mobilized. Site preparation — temporary access roads, erosion control installation required before production work, construction entrance. Temporary facilities — job trailer, portable toilets, temporary fencing, storage containers. First permits and inspection fees if not in a separate line. Superintendent time for site setup before first production day. On a $600K civil project, a properly documented mobilization package is typically $25,000–$45,000 — 4–8% of contract value. That is a real cost that deserves a real line item.
Everything Required to Close Out the Site
Equipment transport off site — same trucking cost as mobilization in most cases. Temporary facility removal — trailer removal, fence removal, container removal. Site cleanup and restoration — removing temporary access roads, restoring disturbed areas outside the permanent scope, cleaning up staging areas. Final erosion control inspection and certification. Demobilization is typically 50–75% of mobilization cost. On the same $600K project, $15,000–$25,000 is a reasonable demobilization line.
SEPARATE LINES WITH SEPARATE COMPLETION TRIGGERS — NOT BUNDLED.
The negotiation: Present the mobilization and demobilization lines at contract signing with a cost breakdown. Equipment transport at $X, temporary facilities at $X, site setup at $X. GCs understand these are real costs. A transparent cost breakdown is easier to approve than a line labeled "Mobilization — $35,000" with no explanation. The conversation at signing is 10 minutes. The alternative is absorbing $35,000 into overhead on every civil project.
WHEN THE PROJECT IS REMOBILIZED — THAT IS A CHANGE ORDER.
If the project is substantially complete and then requires a return to site for additional scope — owner-directed changes, unforeseen conditions, design revisions — that is a remobilization. It has all the same costs as the original mobilization: equipment transport, site setup, temporary facilities. A properly structured original contract with a documented mobilization cost makes the remobilization change order easy to price and justified to the GC. "Remobilization — same cost as original mobilization per contract" is a defensible change order position. "We need to come back and it's going to cost extra" is a negotiation you will probably lose.
