Document control in construction management

Document control is part and parcel of the important area for construction personnel to look into. The important of this are to help every party involved in a particular construction work get the right information at the right time and it help protecting interest of every party.

Due to the heavy work load personnel tend to be distracted from performing a proper document control. For example, there is important documentation that already being distributed to respective personnel, however the sender had overlook on the acknowledge receipt of the document. Thus if there will be an issue arise mentioned that the document was not received or the sender have not do the submission yet, then the sender will having problem to proof that he actually had distribute that particular document.

Looking at the scenario above, this can indirectly affecting the smooth progress of the project. The document might be needed for the purposed of material approval, notice, application of extension of time or progress claim or design change. When this issue of document control become so critical it will start affecting the completion of the construction work. Some of the issue might have to be solved at arbitration level.

For the sake of a well manage construction works and meeting the goal of any construction project, document control should not be taken lightly. I have to be part of the construction procedure. Regardless how it supposed to be carried out, whether by incorporate any document control software or conventional method, Document Control Have To Be Executed in such a manner which will have a positive impact on the project or construction works.

construction cost estimation : Flexible pavement

Cost estimation for construction of flexible pavement is very important to enable a smooth construction activities in road constructions. In order to do cost estimation of Flexible pavement for road, there are numbers of important information that we need to know about the flexible pavement. Below are some of the important parameter required to enable the cost estimation.

 

1. Flexible pavement structure, dimension and quantity.

2. Construction material required

3. Construction Methodology or work method statement

4. Construction work duration

Construction Material for flexible pavement.

1. Suitable soil (well compacted) for sub-grade
2. Down Crusher Run ( Crush and well Graded Granite stone) for Flexible pavement Sub-base and base course
3. Prime Coat
4. Asphaltic concrete Binder Course (ACB)
5. Tack coat
6. Asphaltic Concrete Wearing Course (ACW)





Estimating construction rate per unit of work

Competitive tendered price is one of the greatest factor to win a construction project. However in any business, one of the main factor is to make money. This is true and also applied to construction industry. Therefore winning a project is just a small portion of construction business but be able to secure and deliver projects within the budget is the main agenda of construction business.


HOW TO ACCOMPLISHED THAT TARGET???????


The answer is knowing how to estimate and doing the breakdown of the BUILT-UP RATE PER UNIT OF WORK.


Building the rate is in theoretically knowing the cost of every single item or component that involved in order to deliver the end product. In general these are some of the item that need to be include while estimating rate per unit work or product.


(1). Cost of the construction material
(2). Cost of the Logistic or transportation
(3). Labor cost
(4). Machinery cost
(5). Allow cost for wastage of material
(6). PROFIT MARGIN


Each of the item, from item no. (1) to item no. (5) need some simple calculation and have to be present into "per unit rate". It is then sum-up to create the cost of construction of a unit product.The next procedure is to apply item no.(6) into the sum-up cost.


For example if the cost of construction of a unit product is "W" and targeted profit margin is "Y%", the profit will be "W" X "Y%". let say that the outcome of this calculation is "Z". Hence the built-Up rate is the sum of "W" + "Z"


Calculation:
Item (1) + (2) + (3) + (4) + (5) = W
Profit Margin = Y %
Profit = W x Y% =  Z
Built-Up rate per unit product = W + Z


Built-up rate offered MUST inclusive of PROFIT and Construction Cost.
