2. Planning principles
Planning is the investigation and forecasting of future events.
Before a construction company submits its Tender Price it must PLAN the future contract so
that the most efficient and economical use of labour and plant is considered. Any contract
which is planned efficiently at Pre-Tender stage will be priced competitively.
a) Objectives of Planning
(i) to show the quickest and cheapest method of carrying out the work consistent
with the available resources of the contractor;
(ii) to ensure by the proper phasing of operation with balanced labour gangs in all
trades continuous productive work for all the operatives employed and to
reduce unproductive time to a minimum;
(iii) to provide an assessment of the level of productivity in all trades so as to
permit the establishment of equitable bonus targets;
(iv) to determine attendance dates and periods for all sub-contractors work ;
(v) to provide information on material quantities and essential delivery dates, the
quantity and capacity of the plant required and the periods it will be on
site;
(vi) to provide, at any time during the contract, a simple and rapid method of
measuring progress, for the contractor’s information, the engineer’s
periodical certificate or the valuation of work for accounting purposes.
In any successful contract there are 3 kinds of Planning:
1. PRE-TENDER PLANNING
2. PRE-CONTRACT PLANNING
3. CONTRACT PLANNING
