MASONRY CLUSTER · CASH FLOW

CASH FLOW FOR MASONRY SUBCONTRACTORS — WHY IT IS TIGHT.

QUICK ANSWER

Masonry subcontractors run tight cash because costs hit immediately and payment arrives 58 days later. Mobilization, labor, material, and overhead all run from day one. The first check does not arrive until the first pay app clears — typically 58 days after mobilization. On a $500K masonry contract that is $60,000–$120,000 in costs deployed before a dollar comes back.

The cash flow pattern in masonry work is structural — it is built into how the work is sequenced, how billing cycles work, and how GCs process payments. Understanding the specific cash flow mechanics of masonry subcontracting is the first step toward managing it instead of reacting to it.

THE THREE CASH FLOW PROBLEMS

WHAT MAKES MASONRY CASH FLOW SPECIFICALLY TIGHT.

PROBLEM 01

Scaffold Erection and Material Delivery Front-Load Costs

Masonry projects require scaffold erection and full material delivery before production billing can advance significantly. Scaffold installation costs $15,000–40,000 and block, brick, and mortar delivery for the first phase happens before the SOV advances past 10–15% complete. The front-loaded cost structure creates a cash gap in the first 30–45 days of the project before billing catches up.

PROBLEM 02

Cold Weather Protection Costs Are Often Uncompensated

Masonry work in cold weather requires heating equipment, propane, and wind protection that is not always included in the original bid. When winter arrives mid-project and cold weather protection is required, the cost is incurred whether or not a change order has been submitted and approved. Cold weather protection that was not in the original SOV and was not billed as a change order is absorbed into margin.

PROBLEM 03

Block and Brick Material Lead Times Create Inventory Carrying Costs

Custom brick or specialty CMU may require 4–8 week lead times. The contractor places the order and pays the deposit before the material arrives. The material sits on site — taking up space and tying up cash — before it is installed. Material deposits and inventory carrying costs are a consistent cash drag on masonry projects with custom or specialty materials.

THE THREE FIXES

HOW TO MANAGE MASONRY CASH FLOW INSTEAD OF REACTING TO IT.

Fix 1: Negotiate a scaffold erection line item in the SOV that bills at 100% when scaffold is erected — so scaffold cost is recovered in the first billing cycle.

Fix 2: Include cold weather protection as a unit price allowance in every masonry subcontract executed in the fall or where project duration extends into winter.

Fix 3: Map material deposit payment dates and on-site delivery dates in the cash forecast — so custom material carrying costs are planned and the LOC draw is sized correctly.

The forecast: A 13-week cash flow forecast built specifically for masonry work maps every project's expected payment date, every payroll run, every material delivery, and every LOC draw week by week. Cash problems visible 8 weeks out instead of Thursday night before Friday payroll. Available at constructioncfo.net/cash-flow-tools

COMMON QUESTIONS

FREQUENTLY ASKED.

Why does masonry work create cash flow problems even on profitable projects?

Because revenue is recognized when billed and cash arrives 45–90 days later. Overhead runs every week. Labor runs every week. On a profitable masonry project the margin is real — it just has not arrived yet. The gap between performing the work and collecting for it is funded by the LOC or cash reserves. When that gap grows — from slow billing, slow collections, or multiple projects mobilizing simultaneously — profitable work produces a cash crisis.

How much working capital do I need for a typical masonry project?

Calculate weekly cash burn — fully burdened labor plus material deliveries plus equipment plus overhead allocation — and multiply by the number of weeks to first payment. On a $400K masonry project with a $22,000 weekly burn and a 10-week mobilization-to-payment cycle, the working capital requirement is $220,000. Compare that to available LOC plus cash before signing. If the gap exists, resolve it before mobilization — not at week six.

Does CFOS build cash flow forecasts for masonry subcontractors?

Yes. The 13-week cash flow forecast is a core deliverable of the Executive Financial engagement and maps each masonry project to its expected payment date based on actual billing cycle and GC payment patterns. The forecast is built at engagement start and updated monthly from closed books. Masonry contractors using CFOS typically eliminate the Thursday-night bank balance check within 90 days of engagement.
