House Mover Construction Vehicle: A large home builder approached the TWT Group to design and develop a prototype construction vehicle to enable his next generation home fabrication strategy. From a clean sheet of paper, TWT created the
basic design of the “house mover” dual vehicle system along with a number of strategies and tools for integrating the vehicle with home fabrication, transportation, and installation. At least eight patents are pending for this innovative system.
In addition to providing key design and engineering services, the TWT Group was asked to become the owner’s representative and technical supervisor during the detailed design and construction phases. As
owner’s representative, the TWT Group provided technical management and direction for the vendor’s engineering group, and verified that vendor’s sub-systems and contractor’s deliverables complied with
technical requirements, contract budget, and schedule milestones.
Fabrication and assembly of the two vehicles has been completed. Testing and tuning of the vehicles will continue when the housing market is more favorable.
