A multi storied shopping complex was deigned in center of matara town. The project quantity surveyor finds the problem regarding actual cost and estimated cost. The project quantity surveyor finds the reasons for that.
The reasons for the difference between actual cost and estimated cost.
The price of some materials has increased after commence the project
Estimated cost is making before commence the works of the proect.estimated cost made by based on past material prices. In this project. At the start of this project, need cement for the structural part. At that time when looking for buy the cement price of cement had increased, because of that had top buy the cement for the present price. Some of materials like sand did not enough for the woks and also then looking for by more there suppliers did not have enough stock. As a result of that they had to buy those, materials for another supplier for higher cost.
Some changes of the plan
During of the wok in the site, civil engineer had found few problems regarding the design. This shopping complex was designed in center of matara city; matara city is normally a very busy place ad also this project land was surrounded by a lot of buildings. Because of that they have to design the site o a suitable for the place. Also regarding also regarding some rules of the government they have to redesign the site. And it's made large cost damage.
Some materials had wasted
During the project materials like sand had wasted due to rain. Because in the sand stored in the outdoor place and it was not covered. Also some sand had rejected by the civil engineer, because there quality not suitable for the work. Also some cement bags had stolen.
Transport and labor cost increased
When the suppliers supplying their materials like sand, cement they had increased their rates because increase of the petrol and diesel.
Labors also difficult t found for expected rates .because of that contractor has to use the labor for higher cost.
Some extra expenses for medical treatments
When the construction is going on some labors not obey the rules regarding safety and it cause a some accident to some workers. Because of that extra expenses happen to the medical treatment.
Applying cost planning, cost controlling and monitoring to this site

Also it is better to include the percent prices of the materials and services. Also it is better to concentrate of future price changes. Also, by dividing this estimate to different part of the project like designing, civil engineering part, tiling, etc.. .we can find exact cost to each part.
In this project, to avoid the difference between actual cost and estimated cost , when cost planning have to identify the client's money availability and also has to give the hundred percent for the clients money.
When during the cost planning period, to avoid the cost damage, we can choose the supplier for the lowest rates. also when cost planning we have to design our materials we are going to se, also when cost planning we can look for redesigning parts of the site and then we can also apply cost planning for that redesigned parts.
