Accompanying control

Key points

  • For large orders increased benefits for accompnying control have been utilized in the field of public authorities on the basis of such requirements in recent years.
  • As a result of the orders, which comprise the entire range of services in planning / awarding / site supervision / financing, the accompanying control is a great challenge for the acting people, which we are able to cover in our office by experienced and competent employees. In particular, the fact that the orders have to be carried out with very little effort compared to the construction sums is a big challenge

Financing

Key points

  • To complement our services, ÖSTAP offers project financing in special cases .
  • Especially „Austrian Softloan“ or export financing are part of our business. Of course these financing instruments are only available under special conditions and in some selected countries. For instance, infrastructural projects like water supply systems or waste water projects in Bosnia and Herzegovina, Albania, Macedonia, among others.
  • In addition to the above mentioned financing instruments other credit possibilities can be arranged with our bank partners. In any case a detailed analysis has to be made for every project.

Road construction

Key points

  • Due to the growing population in rural areas an essential topic are also the erection of the supply and disposal facilities, the construction of the traffic routes and green areas.
  • For this reason, the ÖSTAP GmbH offers not only a comprehensive experience in all areas of wastewater treatment and wastewater management as well as support in planning and execution in the field of road construction.
  • Due to the sealing of green areas, the exposure to surface water is important.
