AI audit of construction documents

Control of design and cost documents from site to occupancy

Independent audit of design packages, estimates and contracts at every stage of the project. Cross-discipline conflicts, inflated cost and the risk of plan-review rejection are found before they reach your budget and schedule.

Project path

Two scenarios for the same project

Both projects go through the same eight stages. In the first, design and cost documents pass an independent MEXUM audit before every hand-off. In the second, comments arrive from the plan reviewer, the lender and the site team — after they have already hit the schedule and the budget.

    For the parties responsible for the project budget

    Developers, lenders, contractors, design firms and private builders work with the same documents but weigh different risks. MEXUM issues a conclusion shaped around the task of each party.

    Protecting the project budget at the document stage

    Developers and owner's representatives get an independent opinion on every package before plan review, tender and approval — without growing the team.

    KEY TASKS
    Substantiated project costDuplicated items, unsupported quantities and unit rates outside the market range, with the items listed.
    Passing plan review at the first submissionPre-check of the package against typical grounds for review comments.

    Regions

    Twenty regions, each reviewed against its own code framework

    You choose the project region when you register and when you submit a document. Review modules, report language and payment currency follow that choice. Frameworks are applied as reference sets — always confirm the edition in force with the local authority.

    Methodology

    The whole document package is reviewed together

    Significant findings usually appear where disciplines meet: mismatches between sets, late changes and calculations that were never reconciled. That is why the audit covers the whole package, in the spirit of an authority plan review.

    01

    Submit documents

    Upload a document package or a single document to your account and choose the project region.

    02

    Specialist review

    Fifteen disciplines: zoning and permitting, architecture, structure, MEP, fire and life safety, energy, cost estimating, contracts and more.

    03

    Code-referenced findings

    Every finding carries a reference to the specific code or standard of the project region.

    04

    Reasoned conclusion

    A conclusion in PDF within 48 hours: findings classified by severity, with an estimate of the cost effect.

    Questions and answers

    Frequently asked questions

    What MEXUM reviews, who it is for, which regions are covered, how long it takes and how it differs from plan review.

    What is MEXUM?
    MEXUM is an online platform for independent audit of construction design and cost documents. You upload a document to your account, specialist AI modules (architecture, structure, MEP, fire and life safety, cost estimating, contracts and more) review it, and you receive a conclusion with findings, references to the applicable code of your region and a severity rating.
    Which documents can be reviewed?
    Design packages (architectural, structural, MEP, fire safety, energy), cost estimates and bills of quantities, construction drawings and specifications, construction contracts, change orders and pay applications, permit submissions, and as-built documentation.
    Who is the service for?
    Developers and project owners, lenders financing construction, general contractors, architecture and engineering firms, and private builders and homeowners who want to check a contractor bid or contract before paying.
    Which regions and standards are supported?
    Twenty regions across the Americas, Europe and Asia-Pacific, including the United States (IBC, IRC, ASCE 7, ACI 318), Canada (NBC and provincial codes), the European Union (Eurocodes EN 1990–1999), the United Kingdom, Australia (NCC), Singapore, the UAE, Saudi Arabia, India, Japan and others. The full list is in the Regions section. Frameworks are applied as reference sets: always confirm the edition in force with the local authority.
    In which formats are documents accepted?
    PDF, DOCX and DOC, and XLSX and XLS. A single file can be up to 50 MB. The result is a reasoned conclusion in PDF within 48 hours.
    How long does a review take?
    A reasoned conclusion in PDF format is delivered within 48 hours of upload.
    How much does it cost?
    Prices are in US dollars and depend on the document and plan. A single review needs no subscription. Current prices are on the pricing page of your account.
    Does MEXUM replace plan review or a licensed engineer?
    No. MEXUM is an independent pre-check. It helps you find errors and inconsistencies before plan review, tender, permit application or lender submission. It does not replace approval by the building authority or the work of a licensed professional.
    What does MEXUM find in estimates?
    Duplicated items, quantities not supported by the drawings, unit rates outside the market range, unjustified markups and contingencies, missing scope and discrepancies between the estimate and the design documents.
    How can a lender use MEXUM?
    A project lender receives an independent review of the borrower's design and cost documents before the financing decision. The developer can grant the lender read-only access to the conclusions for a project, which are collected in the lender's financial monitoring view.
    How is my data handled?
    Documents are used only to deliver your review. Processing providers and cross-border transfers are described in the Privacy Policy. You can delete your documents and account at any time.
    How do I start?
    Create an account, upload a document and pick your region. You can also ask the virtual assistant in the chat or message us on Telegram.
