E-tendering platform for Interseroh
Interseroh Dienstleistungs GmbH (Interseroh) regularly invites tenders for disposal services. At the beginning of 2007, initial attempts were made to use the internet profitably for the submission of tenders. The first step, following registration, was for Interseroh to distribute the tender documents via the internet and activate the system. The tenders were submitted, collated and evaluated as Microsoft Excel files.
In mid-2007, Interseroh approached bifa to make implementation of the submission and evaluations of tenders on a tender portal even more efficient. The design of the planned application was drawn up by Michael Bettin and implemented and put into service at bifa. The portal application was designed to keep the time, effort and cost required for a tender to a minimum. To this end, Interseroh prepares the respective tender documents and a list of the planned contract areas. These areas are imported into a database. The tender system then generates the actual implementation from this data. After a potential tenderer's access has been activated on the portal the individual items can be priced. The German federal states (Bundesländer) with their individual contract areas are displayed automatically. When the tenderer makes their final tender submission they receive a printout, which they then sign with a legally binding signature. Their tender on the portal is then protected against further revisions. At the end of the tender period Interseroh receives an overview of the bidders in the respective contract areas, who submitted the best tender. In the case of the call for tenders for waste glass an additional list of the different collection fractions including the individual quotas was used as the basis for the call for tenders and evaluation. To date three tender procedures have been implemented successfully, in which 97 tenderers participated.
