Construction projects run over budget more often than not, and the most common reason is a business plan that never properly modelled cash flow. In project-based work you can be profitable on paper and still run out of cash waiting on milestone payments.
This sample plan shows how a construction, architecture, or engineering firm structures its project pipeline, manages the cash gap between milestones, and prices its services to hit a margin worth working for.

Market & Customer Analysis
Industry context
When we last checked (October 2026), the value of US construction work in 2025 was $2.16 trillion (US Census Bureau). Engineering geology firms like Birch Bay sell expert time on site investigations, so payroll is the cost that decides whether a year is profitable.
A common rule of thumb for technical consultancies is to keep total payroll under about half of revenue. Birch Bay just meets it in year one, with salaries and wages of $338,700 at 49% of $684,300 revenue. It goes over in year two (52%) and year three ($561,800, or 51% of $1,096,400) as the plan adds geologists, hydrologists and engineers to expand capacity.
The result is a thin net margin. Year-one net profit of $11,000 is 2% of revenue, and year three's $43,300 is 4%. Monthly fixed costs of $35,600 at a 64% gross margin put break-even at $55,600 a month, against an average of $57,025, so a single slow month can wipe out the headroom.
Retainage is where that matters most. If clients held back 5 percent of year-one billings, $34,215 would be tied up, more than three times the year's profit. A reserve of three months' fixed costs, a cushion lenders often look for, would be $106,800.
