Abstracting

The skill of preparing an abstract lies in the ability of the worker-up to arrange
the items abstracted from the dimension sheets in bill order. This may not seem
too difficult a task to anyone who has not tried it, but when tender documents are
being prepared in a rush against a tight deadline (which must be 99% of the
time!) the worker-up may be handed the dimension sheets in small lots but must
lay out his abstract to accommodate items he has not yet seen.

Tender Procedure

 

This system comprises standard letters of invitation,stated procedure for bidding, simultaneous notice to bidders, minuted pre tender meetings, controlled points of interaction between company and bidders, defined scope of works,specifications, terms of reference etc.

The seven main steps in the tender process are

1. Tender process is determined: the organisation requesting the tender will determine the type of tender that will be used, as well as what will be involved in the tender process.

 

2. Request for tender is prepared: the request for tender outlines what is required, the contractual requirements and how you should respond.

3. Tenders are invited: the value, complexity and business category determine how tenders are invited.

4. Suppliers respond: you should first obtain all relevant documentation. Then:

a. Attend any pre tender briefing sessions being conducted
b. Clarify any uncertainties
c. Plan your response
d. Prepare your response
e. Submit your response in the right format, on time and at the right location

5. Evaluation and selection: each tender will be checked for compliance, and if compliant, then evaluated against the criteria specified in the tender documentation. The tender that offers best value for money will win the business.

6. Notification and debriefing: when a contract has been awarded, the successful tenderer will be advised in writing of the outcome. Unsuccessful tenderers are also advised and offered a debriefing interview.

7. Contracts established and managed: generally a formal agreement will be required between the successful tenderer and the relevant agency.
