Mainstreet Brick Business Plan — Value Creation Levers

The specific operational and commercial moves that could lift the return above its hurdle, and what each is worth.

Value Creation Levers

Jump to section

Lever	Mechanism	Annual EBITDA impact at Year 3 volumes
Reduce breakage from 3.0% to 2.0%	Handling discipline, curing control and pallet quality; no additional input cost	R540 722
Reduce cement dosage by 3% through mix optimisation	Aggregate grading and calibrated batching at specification rather than above it	R456 531
Cut bad debts from 1.5% to 0.75% of revenue	Credit vetting, individual limits and stop-supply enforcement	R393 375
Shift 5% of stock brick capacity to M140 blocks	Worth far less than a per-unit margin comparison suggests, because a block consumes 6.4 brick slots	R6 480
Add a third shift once demand supports it	Spreads fixed overhead across more units; requires demand not assumed in this plan	Material, but requires demand not assumed in this plan

The ranking matters more than the individual figures. The three operational disciplines — breakage, cement dosage and bad debts — are worth R1 390 628 a year combined, which is 26 per cent of Year 5 EBITDA and would take the project return from 15.5 per cent to comfortably above its hurdle. None of them requires capital, a new customer or a price increase. All three are within the plant manager’s and the finance manager’s direct control from the first month of production.

The mix shift is the lever everyone reaches for and the one worth least

A comparison of unit margins — 28 per cent on a stock brick against 40 per cent on an M140 block — makes the mix shift look like the obvious profit lever, and most brick business plans lead with it. Measured against machine capacity, shifting five per cent of stock brick capacity to M140 blocks is worth about R6 500 a year: less than one per cent of what cutting breakage by a single percentage point delivers. The reason is arithmetic rather than strategic. A stock brick earns R520 per thousand brick-equivalent capacity slots and an M140 earns R532 — a two per cent advantage, not a fifty per cent one, because the block consumes 6.43 slots to produce one unit. The mix strategy should still be pursued, but for the reason given in Section 4.2: blocks are specified rather than chosen, and a specified product is defended against the price war that Section 15 identifies as the existential risk. It is a defensive lever, not a profit lever, and presenting it as the latter misdirects management attention away from the three disciplines that actually pay.

16.1 What each discipline requires

Discipline	Target	What it requires in practice	Who owns it
Breakage and rejects	Below 2.0% of production	Handling training, curing control, pallet condition, stacking discipline and a daily reject count reconciled to production	Production manager
Cement dosage	At specification, not above	Properly graded aggregate, a calibrated batching system, and strength testing that gives the confidence to run at specification rather than comfortably above it	Production manager
Bad debts	Below 0.75% of revenue	Credit vetting before first delivery, individual limits, system-enforced stop-supply, and credit insurance on concentrated accounts	Finance manager
Cement procurement	Volume-based supply agreement	Negotiated before commissioning; a cap or notice period on increases where obtainable	Managing director
Contracted offtake	40 to 50% of capacity	Sales manager appointed six months ahead of production; agreements signed before construction capital is drawn	Sales manager

Each of these is measurable weekly from data the plant already produces, and each has a single named owner. That combination — a number, a target and a person — is what separates a value creation plan from a list of intentions, and on a project with a one-point shortfall against its hurdle it is the difference between an investment that works and one that does not.
