How to Calculate the Unit Price of Partition Wall Work
Partition walls are non-load bearing walls that divide a space into separate rooms or areas. They can be made of various materials, such as wood, gypsum, concrete, or metal. Partition walls have many advantages, such as improving the layout, acoustics, privacy, and aesthetics of a space. However, they also have costs associated with their installation and maintenance.
To estimate the cost of partition wall work, one needs to perform an analysis of the unit price (Analisa Harga Satuan Pekerjaan or AHSP) of each component involved. The AHSP is a method of calculating the cost of construction work based on the quantity, quality, and specifications of the materials, labor, equipment, and overheads required. The AHSP can help contractors, clients, and consultants to plan, budget, and control the construction project.
The AHSP of partition wall work can vary depending on the type, size, shape, and location of the partition wall. However, a general procedure for calculating the AHSP of partition wall work is as follows:
Identify the type and dimensions of the partition wall. For example, a partition wall made of gypsum board with a thickness of 9 cm and a height of 3 m.
Determine the quantity of materials needed for the partition wall. For example, the number of gypsum boards, studs, screws, joint tape, joint compound, paint, etc.
Find out the unit prices of the materials from reliable sources, such as suppliers, catalogs, or online databases. For example, the unit price of a gypsum board with a size of 1.2 m x 2.4 m is Rp 75.000.
Multiply the quantity of materials by their unit prices to get the total material cost. For example, if 10 gypsum boards are needed for a partition wall with an area of 7.2 m2, then the total material cost is Rp 750.000.
Estimate the labor cost for installing and finishing the partition wall. This can be based on the average wage rate of workers in the area or the complexity and duration of the work. For example, if two workers can install and finish a partition wall in one day with a wage rate of Rp 100.000 per worker per day, then the labor cost is Rp 200.000.
Estimate the equipment cost for using tools and machines for the partition wall work. This can be based on the rental fee or depreciation cost of the equipment. For example, if a drill and a saw are rented for Rp 50.000 per day each, then the equipment cost is Rp 100.000.
Estimate the overhead cost for managing and supervising the partition wall work. This can be based on a percentage of the total direct cost (material + labor + equipment) or a fixed amount per unit area or volume. For example, if the overhead cost is 10% of the total direct cost, then it is Rp 105.000.
Add up all the costs to get the total cost of partition wall work. For example, Rp 750.000 + Rp 200.000 + Rp 100.000 + Rp 105.000 = Rp 1.155.000.
Divide the total cost by the unit area or volume of partition wall work to get the unit price of partition wall work. For example, Rp 1.155.000 / 7.2 m2 = Rp 160.417 per m2.
The AHSP of partition wall work can help to compare different options and alternatives for partition wall design and construction. It can also help to monitor and control the actual cost and performance of partition wall work during execution.
