Chapter 3–Construction Cost Control Principles
The cost contral is include the Time-Cost Relationship
To quote”Chitkara ( 2005 ) said the relationship between clip and cost is a really of import facet in the control of costs on site as any fluctuation in clip has automatic deduction on cost. It is of import to describe and enter all the plants affecting stuffs, works and labor on sites. This enables the
contractor be able to cognize the costs and disbursals of the resources used on site and comparison with the initial cost budget. Assorted study techniques used include ; day-to-day or hebdomadal and monthly recording, agenda control, site day-to-day diary study and the undertaking budget.”

Poor Project Management
Harmonizing to User’s Guide, ( 2005 ) , a hapless undertaking direction construction will hold an impact at all phases of the building procedure taking to:
- Lack of planning and coordination ;
- Poor communicating between members of the undertaking squad and the undertaking patron ;
- Failure to place jobs and establish necessary and timely design and scheduling alterations ;
- Lack of control over clip and cost inputs ;
- Lack of terminal user engagement
A good undertaking direction manages costs by gauging, programming, roll uping and analysing cost informations, and eventually implementing steps to rectify jobs related to cost.

refers to the existent value of the building costs with the planned value of the
difference. Deviation analysis may be used to a saloon chart method, signifier method, curve method
Curve is a entire building cost curve ( S line curve ) for the partial building costs differential analysis methods. A figure which indicates the existent value of the building cost curve, p. building cost of the strategy said the value curve, the curve between two perpendicular distances between building cost divergences. The method used is the same image analysis, and ocular features, but this is really hard to direct for quantitative analysis of quantitative analysis can play a function.
During the executing stage of your undertaking, you will necessitate to supervise the position of the activities. Any divergence to agenda, quality, or range for an activity will most probably have a cost impact.

3.1 Budget estimating based on a client’s, contractor..
To quote” The Government cost estimations should be prepared like the Government more cautious and full-equipped contractor gauging the undertaking. Therefore, all costs, which a prudent, experient contractor would anticipate to bear, should be included in the cost estimation. This doctrine widespread throughout the full undertaking rhythm – from programming through completion of building. Each estimation should be developed every bit accurately as possible, every bit item as possible be assumed, and be based upon the best information available. This aim is to be maintained so that, at all phases of the undertaking scheduling, design, and during building, the cost estimation in each facets representation the “ just and sensible ” cost to the Government.”UNIFIED FACILITIES CRITERIA ( UFC ) HANDBOOK: Construction Cost ESTIMATING;hypertext transfer protocol: //www.wbdg.org/ccb/DOD/UFC/ufc_3_740_05.pdf
