Sewerage renewal in Århus The municipality of Århus has recently made use of the partnering model in offering tenders for framework agreements for renewing sewage lines, using both excavation-free methods and excavation.
DDH Consulting A/S assisted Århus Municipality with preparing tender documents, and also assisted the contractor in connection with subsequent negotiations and comparisons of tenders.
The municipality expects to save 10% or to get 10% more sewage system renewal for the same amount of money over a 4-year period. At the same time, the municipality expects increased standardisation of tasks, better solutions, and a more interesting working day for its employees.
The municipality is divided into two areas, with a team composed of employees from all partners attached to each area. The two teams are to exchange information, ideas, etc. at annual workshops, so that the best solutions are always utilised in the entire municipality.
The framework agreement is supplied for tender according to the EU tender directive, with a preliminary prequalification. The target price is based on the unit prices on the tender list as well as specifications of amounts in a preliminary planning phase. All parties are included in the planning phase, so that optimal solutions are reached, such as whether to use excavation or excavation-free methods.
The target budget is fixed for a year at a time, so that all parties know the economic framework for the year in question. |
