Tender Management for Plant Construction

As experienced technical consultants, we support our customers in the preparation of substantiated tender documents and the analysis of offers received.

In plant engineering, comparability of incoming bids is essential for subsequent evaluation and decision-making. As an experienced technical consultant, we support our customers not only in preparing well-founded tender documents for bidding general contractors and EPCs, but also in analyzing the incoming bids.

Focus on comparability and quality

As part of our tender management 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.

When does a tender management service make sense?

If you are planning the construction of a PV solar power plant, but are currently unable to run a solar tender yourself, we can conduct one for you, using our professional tender management services, which include detailed specifications for the tender itself, tender documents, and an evaluation of the layout and designs, along with suggestions for improvements where necessary.

We are experienced technical consultants and can handle the entire solar tender process on your behalf, by preparing well-founded tender documents for bidding by general contractors and EPCs, and we can also analyze the incoming bids.

Transparency and comparability for optimum results

Our systematic tendering process ensures transparency of the current situation by providing details of the project, such as site analysis and grid capacity and design specifications, such as the DC/AC ratio. We also specify components that the incoming offers must contain, including certain information on components, such as data sheets, explanations on layout and design or the calculation of planned cable lengths. These specifications enable us to make the best possible comparison and subsequent evaluation of the individual offers. In doing so, we highlight certain aspects of the plant layout, the expected yields and questions regarding the most efficient operational management later. We also evaluate the price-performance ratio of the suppliers.
