WHY DEMOLITION CONTRACTORS RUN OUT OF CASH BEFORE THE JOB REALLY STARTS.

QUICK ANSWER

Demolition mobilization is front-loaded cost without front-loaded cash. Equipment moves, permits, abatement surveys, hazmat remediation setup, and initial debris haul all occur in the first 7 to 14 days of a demolition contract. The first pay application typically covers that work but does not arrive until day 35 to 45 after submission. A demolition contractor starting two or three jobs per month is constantly funding 30 to 45 days of mobilization costs from cash reserves — or from a line of credit that maxes out when the pipeline grows.

CFOS maps demolition mobilization costs by project against expected first payment dates in the 13-week cash forecast. When the gap between mobilization spend and first payment creates a cash floor breach, the forecast shows it 6 to 8 weeks out — not Thursday morning.

Typical Front-Loading Protection
Most demolition contracts do not include mobilization advances or front-loaded schedule of values. The contractor funds the gap entirely from working capital.
FAILURE CHAIN 01
The Mobilization Gap

A demolition contractor starting a $400,000 selective demolition job on a commercial renovation project incurs $65,000 in the first two weeks — equipment mobilization and rigging, hazmat abatement contractor, debris haul permits, temporary utility disconnections, and initial dumpster costs. The first pay application covering that work is submitted at the end of week two. The GC approves it by day 30. Cash arrives by day 38 to 45.

From day 1 to day 38, the contractor has $65,000 deployed with nothing collected. On three concurrent jobs at different phases, the total mobilization float can be $150,000 to $200,000 at any given time. Without a 13-week forecast that maps this explicitly, the owner finds out about the cash constraint on the day it hits — not 6 weeks out when there is time to arrange LOC headroom or adjust timing.

FAILURE CHAIN 02
The Schedule of Values Problem

Most demolition subcontracts use a simple schedule of values — a percentage of contract broken into phases or time periods. If mobilization represents 18% of the job cost but only 8% of the contract value in the SOV, the contractor is fronting 10% of the contract value before the billing catches up. On a $400,000 job that is $40,000 out of pocket before the billing structure starts recovering the true front-loaded cost.

CFOS reviews the SOV before the contract is signed. When mobilization costs are significantly front-loaded, CFOS negotiates a mobilization line in the SOV that reflects the actual mobilization cost. A $65,000 mobilization cost on a $400,000 contract should be a 16% line on the SOV, not a 5% general conditions allocation.

FAILURE CHAIN 03
The Abatement Subcontractor Problem

When demolition scope includes asbestos, lead paint, or other hazmat abatement, the abatement subcontractor typically requires payment within 30 days regardless of when the GC pays. The demolition contractor is caught in the middle: the abatement sub wants payment in 30 days, the GC pays on net 45, and the demolition contractor funds the gap from working capital.

CFOS maps abatement sub payment obligations against expected GC payment dates in the weekly cash forecast. When the gap creates a payment timing problem, CFOS identifies it early — negotiating abatement sub payment terms, arranging LOC coverage for the specific gap, or flagging the issue to the GC for early pay application approval on the abatement line.

01
Map Mobilization Costs in the 13-Week Forecast
Every demolition job in the pipeline gets a mobilization cost entry in the 13-week forecast — estimated amount and estimated date. Mapped against the first expected payment date. The running cash balance shows the mobilization gap explicitly so it is managed proactively.
02
Negotiate a Mobilization Line in Every SOV
Before signing any demolition subcontract, review the schedule of values structure. If mobilization represents more than 10% of job cost, negotiate a specific mobilization line that reflects the actual cost — not a generic general conditions percentage. This recovers mobilization cash 2 to 3 weeks faster.
03
Manage Abatement Sub Payment Timing
When abatement subcontractors are involved, map their payment obligations against GC payment dates in the weekly forecast. Options include negotiating extended terms with the abatement sub, arranging targeted LOC coverage, or requesting early approval on the hazmat line of the pay application.
04
Submit Pay Apps the Day Work Completes
Demolition pay apps should be submitted the day a phase or milestone is complete — not held until end of month billing cycle. Every day of delay in submission is a day of delay in collection. On a $65,000 mobilization pay app, a 7-day submission delay is 7 additional days of working capital deployed.

COMMON QUESTIONS

FREQUENTLY ASKED.

Because demolition is uniquely front-loaded — mobilization, permits, abatement, and initial haul all occur in the first two weeks before the first pay application even goes out. Combined with 35 to 45 day payment cycles on commercial contracts, demolition contractors routinely fund 6 to 8 weeks of mobilization costs from working capital before the first dollar is collected.
Mobilization should be a specific line item reflecting actual mobilization cost — equipment moves, permits, abatement setup — not buried in a generic general conditions percentage. If mobilization is 15% of job cost, it should be approximately 15% of contract value on the SOV. This recovers mobilization cash as soon as the work is complete rather than spreading recovery across the entire project duration.
