Representative Projects

Intermountain Electronics
Crypto Mining Cold Formed Buildings

KAHUNA USA was tasked with validating several crypto mining buildings for our client. Initially intended to reside in areas with low snow loads. However, during analysis it was discovered  the loads in the new building locations were as high as 50 PSF, a 10-fold increase. The roof members were found to be insufficient. KAHUNA USA proposed a solution to retrofit the buildings with additional roof members, attached externally. The solution proposed by KAHUNA USA included  self-tapping screws to attach cold formed channels  to the existing roof members. The client was very pleased they were able to avoid a complete redesign of the roof system thanks to the successful execution of this structural design project by KAHUNA USA.

Eagle Claw East Toyah Plant

East Toyah presented KAHUNA USA with a unique structural problem. To access the new areas of the facility expansion, Eagle Claw needed to extend their pipe rack over a complex existing pipeline corridor which was over 100 FT wide. Due to the abundance of pipelines, locations where foundations could be installed, were limited. As a result, KAHUNA USA developed twin 60 FT pipe bridges that spanned the intricate corridor with one strategic foundation in the center. The pipe bridges were designed to minimize member sizes while maintaining deflections within allowable tolerances. Whether your structural problem is large or small, KAHUNA USA has the resources to expertly construct a solution.

NTACT/Seaboard Optima RNG Facility

Field supervisors contacted KAHUNA USA after a mishap in which the client’s concrete piers were formed and poured approximately four feet lower than shown in the design package. The mistake went unnoticed until concrete was already in the forms. KAHUNA USA Structural team was able to examine options with the client, create multiple solutions, and issue the approved cold-joint solution–all in the same day the concrete was poured. Contact KAHUNA USA for the solution you need to construct efficient and innovative structural engineering results.

We have the Civil + Structural experience you need.
