KAI RENI CHECK

Find the mistake
before the site does.

An independent written review of drawings and BIM models. We find clashes, inconsistencies and weak decisions, and explain what they cost on site and how to fix them while it is still cheap.

Axonometric of a concrete frame with two marked clashes: ductwork vs beam at +15.60 and at +12.00
What we check

A second pair of eyes on the whole set.

Coordination

Clashes between architecture, structure and MEP; levels, openings, shafts.

Documentation

Plans against sections and schedules; tags, grids, dimensions.

Layout logic

Circulation, ergonomics, accessibility, relationships between rooms.

Model quality

Categories, parameters, worksets, naming and QA/QC readiness.

Constructability

Details and sequences that will be hard or costly to build.

Root cause

Where errors come from in your process and how to stop them repeating.

Process

From files to findings in five steps.

  1. Send files

    A link to drawings or a model and what worries you.

  2. Quote in 24 h

    Scope, price and turnaround in writing.

  3. NDA & invoice

    NDA if you need one. 100% upfront for private clients, 50% for companies.

  4. Review

    At most two projects in work at a time, so yours gets attention.

  5. Report & call

    A PDF report; a call for Full Check.

Sample finding

Every finding answers five questions.

A report opens with a one-page verdict and the three main findings, then lists every issue by priority, what is done well, and the limits of the review.

Sample from a fictional project.

R-01Critical
Where
Level 02 · grid C–D / 4 · corridor ceiling
What is wrong
A 600 × 300 supply duct runs through a 300 × 600 beam. Clear height under the beam is 2.35 m; the duct needs 2.55 m.
Cause
The MEP model was coordinated against an earlier structural revision.
On site
Rework: a new duct route or an opening in the beam, both after delay.
Fix
Reroute along grid 5, or agree a reinforced opening with the structural engineer.
Request

Tell us about the project.

You get a written quote within 24 hours on working days. Materials are used for your review and processed by the providers listed in Privacy. For confidential files, arrange an NDA and access-controlled sharing first.

We decline projects where we could have a conflict of interest, and say so straight away.

Models are usually larger than 8 MB, so a link works best. You can also send files after the NDA.
Questions

Before you send files.

Which files do you accept?

PDF drawings, DWG, Revit (RVT) and IFC models, and photos of printed plans. Share large files with a link.

Does the review replace official expertise?

No. It is an independent professional opinion on the materials you send. It does not replace official review, structural calculations or permits.

How do you keep projects confidential?

Files are used for your review and can be deleted on request. The hosting and data providers are listed in Privacy. If you need an NDA first, submit the request without files or links; we will agree on a protected sharing method.

Can you fix the model for us?

We review and explain. Your team or designer makes the changes; we can check them again at a reduced price.
