Build a house, a good simple home, home being, as well as luxury homes, homes to live alone or as an investment property in the future as well as public consumption requires no small cost. This requires careful calculations, both the amount of the cost of manufacture, the volume of work and type of work, materials prices, labor costs, and plans and the terms of employment. It is intended that the cost of making the efficient and scalable according to the plan drawings. In building construction, it is called Plan
Budget (RAB) which is usually disetalikan with the Work Plan and Technical Terms (RKS).
Some of the advantages when we first calculate the cost of home-making processes are as follows;
1. Type of work is what will be used to held / purchased.
2. Volumes kinds of materials that will be needed to make the house can be seen.
3. Total cost required for the manufacture of the house can be estimated so that the velocity k euangan can be arranged.
4. Owners can be helped in negotiating contractor bid price or the second (if the house construction work will be done by someone else) so it will not harm the owner of the first party.
5. Job-any job that has not yet been completed or (if done the second / other people) can be controlled.
Knowledge of the RAB and RKS in the manufacture of building work / home stay would be very beneficial, as it will make it easier to understand the various issues related to development, among others, to understand the equipment to be used in building, building materials, material requirements, power requirements, processing time ( implementation). The existence of such an understanding will berdamapak on knowledge of funding requirements, material requirements, control, and its use in each stage of the work.
The basis of the RAB and RKS is to understand the planning image, so it can be calculated the amount and type of building materials to be purchased for development. In building terms this is known as the volume of work. Volume is the number of jobs or materials with different units, depending on the needs in any kind of work performed.
The volume in question could be in the form of units of length (m1), the area (m2), content (m3), fruit (bh), units, lum sum (Ls). While the price of building materials and labor costs rates may vary, depending on the place and time of manufacture.
