About

One construction company, three work areas.

HAP-Rakennus OY is a construction company working in three areas: roofing and waterproofing, construction, and plastering and facades. Roofing is delivered under the Nordic Bitumen brand. The areas are a way of organising the work, not separate companies. The same company signs the contract and answers for the work, whichever area a project belongs to.

  • A HAP roofer in a safety harness on a pitched roof, a ladder beside him.
  • A broad pale flat-roof surface with its seams, buildings and forest far behind.
  • A flat roof under work: a worker in a hi-vis vest and rolls of membrane, an orange building behind.

How we work

The same company answers for the work.

A project may involve one work area or several. That changes neither who does the work nor who it is agreed with.

  • One party to the contract

    The contract is with HAP-Rakennus OY. Nordic Bitumen is the brand roofing is sold under, not a separate party.

  • Scope decides the area

    A facade belongs to plastering or to construction according to what is actually done to it, not according to the word the project falls under.

  • The scope is agreed before work starts

    The site is walked, the work is bounded and the schedule is agreed together. After that there is one person responsible on site and one contact for commercial matters.
