About
Tender Management
Focus on comparability and quality
As part of our tender management system service, we ensure that all project-relevant aspects and special features are taken into account. In this way, we ensure that you receive the required level of quality of execution in terms of normative and customer requirements during the subsequent implementation. The concrete planning specifications and structure of the tender documents also ensure good comparability of the individual bids. However, we remain flexible and always make sure that we leave enough room for innovative proposals and ideas from suppliers.
The greentech team maintains close contact with both the customer and the participating companies in order to clarify queries and conduct discussions, in the interest of the customer, for optimum results in terms of price and quality.
Thanks to our technical expertise and a comprehensive overview of the market, we are able to critically evaluate the components and plans on offer and negotiate with the suppliers on an equal footing.
