Define Tender
Offer by a contractor to undertake a specified piece of work or programme for a quoted sum
What’s the difference between a Type 1 and Type 2 tender
Type 1= Standing Offer, the acceptance of which doesn’t create a binding contract
Type 2= If accepted creates a legally binding contract
Methods of Tendering
-Open (Traditional)
-Single Stage Selective
-Two Stage Selective
-Negotiation
-Competitive Dialogue
Characteristics of Open Tendering
-Advertisement in the technical press inviting interested parties to apply for tender documents
-Everyone has equal opportunities to tender and everyone has the same info
-Employer is not bound to accept the lowest or any tender
Advantages of open tendering
Results in very competitive tendering prices
Creates opportunities to a larger number of contractors
Better competition
Traditional method, so familiar to everyone in the industry
Disadvantages of open tendering
Can result in a contractor who has little experience being chosen (no reliability about the quality of the work)
The tender process takes a long time- expensive
Unreliable competition
Characteristics of Single Stage Selective
o A short-list of suitably qualified contractors are invited to tender for the proposed works- these names may be pre-approved or drawn up through a pre-qualification process
o Useful as simple
o Most popular tending form for large contracts
Advantages of single-stage
Reduces tendering costs and time
Can select a reliable experienced contractor
Disadvantages of single-stage
Tendering prices not as competitive as there is less competition
Difficult for new firms to obtain work
Can be biased
Characteristics of Two-Stage Selective
Stage 1: Selection of contractor through competitive tendering, and the establishment of a pricing basis for future negotiation
Stage 2: Selected contractor provides required paperwork and submits price bid
o Contractors don’t like this route as much
o Contractor selected on the basis of an approximate bill of quantities, the contractor then works closely with the design team and a final tender is submitted based on bill prices previously outline in the successful competitive tender
o Used where the selection of the right contractor is of paramount importance due to an early start being required or the need for technical contribution from the contractor
o More convoluted
Characteristics of Negotiation (nomination)
o Special case of selective, but the shortlist contains only one name
o Contractor may be selected by direct negotiation
o Challenge the contractors quoted price- can work with them
o Used with specialist contractors, a single firm is asked to submit a tender which is negotiated between the quantity surveyor and contractor
o Price tends to be higher than open competition and leads to problems for new firms
Advantages of negotiation
Time consumption low
Can select a reliable, experienced contractor at a reasonable price
Contractor can contribute their expertise during design stage
Can lead to early commencement of work on site
