    Cost estimations and cash flow analysis for new as well as upgrading of old installations, both at business and public levels. Preparing applications for loans and governmental funding. Risk analysis.

  3. Projecting.

Specifications and quantity calculations. Preparation of building reports, crossing license applications and technical documentation.

  4. Building structures.

    Statical calculations with advanced computer programs such as Staad III. Projecting of steel, concrete, aluminium and wood constructions based on Norwegian, Danish and British standards.

    Preparation and evaluation of quotation documents and arranging contract meetings. We also prepare contracts and do the following up and control during the construction period.

  6. Quality assurance.

    Tsabango trafostasjon i Malawi

    We work after the principle that the builder should get a quality assurance that agrees with ISO 9001. This counts for our duties as well as for external duties from i.e. building contractors. The goal is to assure that the final product gets a specified operating security over a certain period of time, depending on the project's social importance.

    The plan for quality securing contains the following subjects:

    • Exactness due to guessing climate loads, avalanche danger, danger of trees falling on the line as well as danger of heavy snow loads.
    • Safety of systems - damage preventing constructions.
    • Quality of projecting and project management.
    • Quality of materials used - logistics.
    • Quality of erection.
    • Operation and maintenance routines.
    • Emergency plans for break down situations.
