The Numbers Behind Construction Waste

Industry data shows where projects bleed money — and where automated audits stop the bleeding

💸

Cost Estimate Inflation

Subcontractor bids routinely include 15–40% markups on materials, inflated labor rates, and duplicate line items. Manual review catches some — automated analysis catches all of them.

$1.6T wasted globally per year
📊

Change Order Creep

82% of commercial projects exceed their original budget. Missing scope items, vague specifications, and incomplete drawings generate change orders at 2–5x the original unit price.

82% of projects over budget
⚖️

Compliance Failures

Plan review rejections, permit delays, and code violations discovered during inspection cost weeks in schedule and thousands in redesign. Early detection eliminates rework.

4–8 weeks avg. delay per rejection

What the Platform Does

Upload. Audit. Act. — Every document type, every building code, every time.

📋

Cost Estimate Audit

Line-by-line verification of material and labor unit prices against current market rates. Flags duplicate items, quantity errors, and inflated markups with fair-price alternatives.

📐

Blueprint & Drawing Review

Structural integrity, load calculations, egress paths, accessibility, fire separation, and energy code compliance. Cross-checked against IRC, IBC, EN Eurocodes, and local amendments.

📄

Contract Risk Analysis

Automated review of construction contracts, subcontractor agreements, and purchase orders for unfavorable terms, liability gaps, missing warranties, and vague scope definitions.

🔄

Change Order Verification

Validates change order pricing against original bid rates. Checks whether the work was in the original scope. Identifies scope creep patterns across your project history.

🏛️

Permit & Compliance Check

Pre-submission review against local building codes, zoning ordinances, setback rules, and energy codes (IECC, ASHRAE 90.1). Reduces plan review rejection rate.

📊

Portfolio Analytics

Track cost trends, overcharge rates, and risk scores across all projects. Identify which subcontractors consistently overbid. Data-driven procurement decisions.

Frequently Asked Questions

What types of construction documents can I audit?
Cost estimates, contractor bids, GMP proposals, blueprints, architectural and structural drawings, MEP plans, construction contracts, subcontractor agreements, change orders, pay applications (AIA G702/G703), specifications, and permit documents. We accept PDF, DOC, DOCX, XLSX, and DWG files.
Which building codes and standards are supported?
IRC, IBC, NEC, UPC/IPC, IECC, ASHRAE 90.1, ADA/ADAG for US projects. EN Eurocodes (EN 1990–1999), DIN, BS, and NF standards for European projects. We also check against local municipal code amendments based on your project location.
How does subscription pricing work?
Each plan covers a set number of document reviews per project. You can start with a one-time $100 trial on a single document. When you see the value, upgrade to a project plan. Plans are per-project, not recurring — you buy capacity when you need it. No long-term commitment.
What if the audit finds no issues?
If our review finds no material issues with your document, you are not charged for that review. You only pay when the report delivers actionable findings. Your remaining review credits stay available for other documents.
Is my data secure?
All uploads are encrypted in transit (TLS 1.3) and at rest (AES-256). Documents are processed in isolated environments and automatically deleted after report delivery. We never share your data with third parties.
Can I use MEXUM reports in contract negotiations?
Absolutely. Reports include specific line items with fair-market price comparisons, code references with section numbers, and detailed explanations. They are designed to serve as independent verification in bid leveling meetings, contract negotiations, and investment due diligence.
Is MEXUM a chatbot or a generic tool?
No. MEXUM is a purpose-built document analysis platform engineered specifically for the construction industry. Unlike chatbots or generic tools, our system runs 14 proprietary specialist modules — each calibrated against construction codes, material pricing databases, and contract law frameworks. Every audit follows a structured methodology: document parsing, cross-referencing against applicable standards, line-item verification, and risk scoring. The output is a professional-grade report, not a conversation.
Who is behind MEXUM?
MEXUM is developed by RENVAR INC., an international technology company focused on construction industry digitalization. We operate across 40+ countries, supporting local building codes and standards from the Americas to Asia-Pacific. Our engineering team combines deep expertise in construction technology, document analysis, and regulatory compliance.
