Technical notes on prefabricated joint analysis, frame testing, and 3D drafting for modular construction.
We performed a comprehensive joint integrity audit on a prefabricated steel frame for a 12-story modular high-rise in Tokyo. Using 3D laser scanning and finite element analysis, we identified 14 joints with stress concentrations exceeding design limits. Our team provided detailed remediation drawings and re-testing protocols, ensuring the structure met JIS standards. The project was completed within a 3-week timeline, enabling the client to proceed with fabrication without delays.

Our clash detection process resolved 23 interferences between steel framing and MEP routes. We delivered fabrication-ready drawings with tolerance annotations, reducing on-site rework by 40%. The project required close coordination with the factory to ensure dimensional accuracy across all units.

The testing included vertical, lateral, and seismic load scenarios per AS/NZS 4600. Our team designed custom test jigs and instrumentation to measure deflection and joint slip. Results showed that 48 frames met all performance criteria; two required minor stiffener additions. We provided a full test report and revised fabrication drawings, ensuring the project passed regulatory review.

Yes. We deliver detailed 3D geometric models with tolerance annotations, clash detection reports, and MEP integration. The output is formatted for direct use in factory CNC and assembly workflows.
We combine 3D laser scanning with finite element simulation to identify stress concentrations. For physical validation, we design custom test jigs and measure deflection under vertical, lateral, and cyclic loads per relevant standards.
A standard audit for a mid-rise modular building (10–15 stories) takes three to four weeks from on-site scanning to final report. Smaller frame assemblies can be completed in one to two weeks.
Yes. Our team has experience with JIS, AS/NZS, Eurocode, and IBC standards. We adapt testing protocols and reporting formats to match local regulatory requirements for each project.
This platform exclusively addresses engineering consulting for prefabricated structural systems. All content, models, and recommendations pertain to load-bearing frame analysis, joint integrity testing, and 3D geometric drafting of modular components. No part of this site constitutes an offer for sale, lease, or valuation of real property.
Reports and drawings provided are based on client-supplied specifications and site data. We assume no liability for field conditions not disclosed or for modifications made to prefabricated assemblies after delivery of our analysis. All structural recommendations must be reviewed by a licensed professional engineer in the jurisdiction of installation.
