Some clients try to avoid a call for tenders by procuring the multi-touch table and its software separately and thus keeping the individual costs under the relevant value limits. Multi-Touch Table – What Should Be Put Up for Tender?Ī multi-touch table project essentially involves the table’s hardware and its software, and, if applicable, also additional services like conception, on-site installation, and maintenance contracts. Usually, a call for tenders is the method of choice for contract values exceeding € 25,000. For instance, with a restricted or invited tender, the contracting authority addresses a limited and preselected group of vendors, only allowing those to submit an offer. Within the margin of a minimum value limit, however, the contracting authority principally can choose between different reasonable tender procedures. This article will provide you not only with practical advice but with a helpful Excel template as well, for an optimal preparation of the tendering process When to Tender?įor public sector organizations and contracting authorities, the standard procedure is an open call for tenders, where an unrestricted number of contractors is invited to hand in bids. While with regards to the project timeline, the call for bids is supposed to be set up and publicized rather sooner than later, often in terms of content still a lot of open questions remain. the hardware, the software, the Content Management System, service etc. One multi-touch table consists of a multitude of separate components, e. A sometimes mandatory public call for tenders does nothing to make the complex procurement procedure any easier. 841–873.More and more often, multi-touch tables are an integral part of showrooms, demonstrators, and exhibitions of research organizations.
