BAU-HOW

Process

Industrialized construction

Industrialized construction processes are not the same as with traditional construction. In order to realize maximum quality and lower building costs, we require that all partners in the project accept that contracts, work processes and interfaces are a bit different.

  1. Analyzing and planning

    The BAU-HOW local office evaluates the project’s suitability for industrialized production and aligns the client’s request regarding delivery time, quality and budget.

  2. Optimizing the project

    If necessary, the BAU-HOW local office proposes preliminary changes to the project to optimize the project’s suitability for industrial product and reduce building costs. This results in a general enterprise contract.

  3. Project design

    The project design is carried out and the technical specifications are described to meet building owner demands and obey national regulations and standard. This work is done by local architect and engineering firms hired and supervised by BAU-HOW and results in a building permit application.

  4. Project engineering

    When the building permit is obtained, the project is submitted to the factory and detailed production drawings are made. This work is supervised by the local BAU-HOW office.

  5. Ground works

    When the building permit is obtained, BAU-HOW subcontractors will commence groundwork and foundations under local BAU-HOW building site management.   

  6. Production

    The modules are manufactured at the BAU-HOW factories in Ventspils, Latvia when the project engineering department is finished.

  7. Transportation

    To protect the modules from moisture during transportation, the module is packed in a water-proof plastic membrane. BAU-HOW transports the modules via the Baltic Sea to the nearest suitable local harbor.  From here the modules are transported by trailer to their final destination.

  8. Erection

    Every evening the modules are carefully covered with plastic sheeting which are welded together to ensure that the modules remain dry. Each module takes 10-15 minutes to erect.
    Factory assembly technicians raise the modules. The joints in the facade core are closed concurrently with the module erection. 

  9. Finishing

    When the modules are assembled, all technical installations are connected in the service shafts, and plaster boards are mounted to cover were the modules join. Outside the last of the façades are finished. All work is carried out by local contractors under the supervision of BAU-HOW building site management.  

  10. Evaluation and Handover

    The handover is done in the same manner as in traditional construction. Any defects or shortcomings are corrected by local subcontractors. When the handover is completed, a thorough LEAN based project evaluation is conducted.
