CNK Lab — Construction & Knowledge

Company

Company profile

CNK Lab — "Construction & Knowledge" — combines practical construction expertise with digital technology to support construction companies in Japan.

About us

Digitising construction, from the perspective of the people who draw.

CNK Lab is an engineering company based in Hanoi, Vietnam. Our two pillars are drafting and BIM / CIM modelling services for design offices and contractors, and software and tool development for construction companies.

"Construction & Knowledge", the phrase behind our name, describes our stance: practical construction expertise as the foundation. Drawings and software alike are built from the point of view of the people who actually use them.

Our leaders have worked at Japanese firms and run drafting and checks through a standardised workflow based on Japanese drafting standards. We work in Japanese from kickoff to delivery, on hours aligned with Japan.

Working with us

How we work with clients

Contracts, information handling and communication follow the same approach on every project, so first-time clients know what to expect.

  • Contract modelsPer-project contracts, or a monthly dedicated team ("lab" model). A first project can start as a small trial.
  • ConfidentialityWe sign a non-disclosure agreement before receiving any drawings. Drawings, specifications and site photos are handled with access limited to those who need it.
  • Communication and hoursEmail and online meetings. We work Monday to Friday, 9:00–18:00 JST, and reply to inquiries within one business day.
  • LanguagesJapanese, English and Vietnamese. Specification alignment, Q&A and deliverables are handled in Japanese.
  • QualityA standardised workflow based on Japanese drafting standards and multi-layer QA / QC by several team members. Products are operated and maintained under an SLA.
