Quarry to Site — Construction Materials Production & Supply Audit Program v1.0

Quarry to Site — Construction Materials Production & Supply Audit Program v1.0

Short description (listing card / meta description)

A risk-led Excel audit program for quarries, ready-mix concrete plants and steel processors. It has 132 procedures, a 60-risk register, a ready-to-send evidence request list, and a Loss Estimator that turns control gaps into money.

Full description

Your weighbridge says 1,000 tonnes left the gate. Your invoices say 940. Where did the other 60 go?

In construction materials, profit leaks out quietly. It goes out through a loaded truck that never crossed the weighbridge, a batch light on cement, a coil that produced fewer sheets than it should, a stockpile that is smaller than the books say, or a diesel tank that never quite reconciles. Most audit checklists never find these losses, because they test paperwork, not the flow of material.

Quarry to Site follows the material from the blast face to the customer’s site. It is built for internal auditors, external auditors, risk managers and consultants who review quarrying, crushing, ready-mix concrete and steel processing operations.

This is a risk-led program, not a checklist. Every procedure traces one golden thread: Objective → Risk → Impact → Expected Control → Procedure → Evidence → Finding. You can show management exactly why each test exists and what it protects.

The program contains 132 audit procedures across 10 distinct sections. It is supported by a 60-risk register scored on five impact dimensions, and by a Loss & Yield Estimator that puts a value on what the business is losing.

Built around recognised practice

• Structured on COSO internal control principles and the IIA’s risk-based audit approach.
• Covers controls expected under quality, environmental and occupational health & safety management systems (ISO 9001, ISO 14001, ISO 45001).
• Jurisdiction-neutral: regulators and product standards are described generically, so it works in any country.

What the program covers

Section 1 — Governance, Licensing & Regulatory Compliance (14 procedures) Confirms that licences, permits and product certifications are valid, and that royalties and levies match actual production. It also tests whether authority limits and segregation of duties prevent management override.

Section 2 — Quarry Extraction, Blasting & Crushing (14 procedures) Tests blast authorisation, explosives custody and reconciliation, crusher production recording and stockpile surveys. The aim is to confirm that everything blasted and crushed is accounted for.

Section 3 — Weighbridge, Dispatch & Haulage (15 procedures) Covers the most common leak point in the industry. It looks for trucks that bypass the scale, manual overrides, tare manipulation, voided tickets, loads that are never invoiced, and haulage trip fraud.

Section 4 — Ready-Mix Batching & Delivery (14 procedures) Checks batching against approved mix designs and reconciles cement and aggregate usage to concrete produced. It also controls returned concrete and confirms that every delivery and pump hour is billed.

Section 5 — Steel Processing & Fabrication (13 procedures) Verifies coil receipts and incoming quality and measures coil-to-product yield. It exposes off-book production and confirms that scrap and offcuts are recorded and sold at value.

Section 6 — Procurement & Raw Materials Inventory (13 procedures) Tests supplier selection and pricing, supplier master data, bulk material receiving and stores inventory. It also covers diesel control, one of the biggest sources of loss on any site.

Section 7 — Sales, Pricing, Credit & Revenue (13 procedures) Confirms that approved prices and discounts are applied and that credit is extended prudently. It also checks that cash and mobile receipts are banked and that revenue is complete and recorded in the right period.

Section 8 — Plant, Equipment & Calibration (12 procedures) Verifies that assets exist, are insured and are maintained, and tests maintenance costs for fraud. It also confirms that weighbridges, batching scales, belt scales and fuel pumps are accurately calibrated.

Section 9 — Quality Assurance & Product Conformity (11 procedures) Tests cube strength and aggregate grading results, the integrity of laboratory data, non-conformance handling and customer complaints. This protects the business from structural-failure liability.

Section 10 — Health, Safety & Environment (13 procedures) Assesses blasting and machinery safety, dust and silica exposure, incident reporting, environmental permit compliance, rehabilitation liability and contractor safety.

What makes it different

• Suggested evidence on every procedure. Each procedure names the documents to request, the evidence type and the person who holds them, so you know what to ask for and whom to ask.
• “What to look for” red flags. Practical warning signs from the field are built into every procedure, for example: “Identical tare weights on different trucks” or “Cement consistently under target in batch reports.”
• Ready-to-send Evidence Request List. 260 documents are grouped by owner, with status tracking and overdue alerts. Filter the list, send it to the client, and start fieldwork with the evidence already in hand.
• Loss & Yield Estimator. Five calculators cover Cement Yield, Aggregate Stockpile, Weighbridge vs Invoicing, Steel Coil Yield and Diesel Efficiency. They turn “controls need improvement” into “you are losing about $132,000 a year”, and that is the kind of finding that gets action.
• 60-risk Risk Register. Each risk is scored for Financial, Operational, Safety & Environmental, Regulatory and Reputational impact. Inherent and residual ratings calculate automatically as you assess controls.
• Executive Dashboard. Section scores, inherent and residual heat maps, the top 10 risks, findings by rating and total estimated leakage all update live, ready for your report and exit meeting.

What’s included

• 1 Excel workbook with 16 tabs, with no macros and no add-ins required.
• 132 audit procedures across 10 colour-coded sections, organised under 40 audit objectives.
• A 60-risk Risk Register with impact and likelihood scales defined.
• Suggested evidence, evidence owner and red flags for every procedure.
• An Evidence Request List (260 items, 28 owners) with tracking.
• A Loss & Yield Estimator with 5 calculators and adjustable tolerances.
• A Findings Log (Condition, Criteria, Cause, Impact, Recommendation, management action tracking).
• An auto-scoring Dashboard with heat maps and a top 10 risk table.
• An About tab with a section navigator, how-to-use guide and rating definitions.

Who it’s for

• Internal audit teams in quarrying, mining, cement, concrete and steel businesses.
• External auditors and audit firms with construction-materials clients.
• Risk, compliance and loss-control managers.
• Consultants carrying out operational, forensic or due-diligence reviews.
• Diversified groups and holding companies overseeing industrial subsidiaries.
