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.

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.
Pick a sample below and watch the specialist modules work through it: from package completeness to cost.
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.
Developers and owner's representatives get an independent opinion on every package before plan review, tender and approval — without growing the team.
For project lenders: an audit of design and cost documents against the codes of the project region before the credit decision, and access to conclusions for the life of the facility.
General contractors find conflicts and errors in quantities before signing the contract and mobilizing, when the cost of correction is lowest.
A design firm gets an independent check of its sets before hand-over to the client or submission for plan review — no outside specialists and no slip in the issue date.
The owner of a private home gets an independent review of the estimate, the plans and the contract before paying for work, with a list of items to renegotiate.
The same set of documents is read differently by each party. Pick the role closest to yours.
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.
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.
Upload a document package or a single document to your account and choose the project region.
Fifteen disciplines: zoning and permitting, architecture, structure, MEP, fire and life safety, energy, cost estimating, contracts and more.
Every finding carries a reference to the specific code or standard of the project region.
