Detail Process for Preparing Bill of Quantities (BoQ)

A Bill of Quantities (BoQ) includes the overall materials on the basis of which the architectural design of a project for the construction is done, like for example a house or different structure. Furthermore, the BoQ offers nearly appropriate quotes with respect to the project.

A civil engineer or quantity surveyor with expertise at determining the materials required for a project, particularly make BoQs.

Create a spreadsheet for bill of quantities having columns with respect to the item numbers, specification or description, measurement unit, amount, rate with respect to the item, labor, as well as overall expense for the item. Furthermore, the item numbers must be consecutive, starting from one. Moreover, again start the item numbers per section or sort of the build.

Furthermore, the columns with respect to the rate per item as well as overall costs are included by contractors who bid on the project. Generally, there’ll be no values in these columns when preparing the BoQ.

Creation of a List of Materials to Finish the Project

On the basis of plans of the architects, note down an elementary list of the entire required building materials necessary as well as the quantities needed of every. It includes hardware, wiring, as well as different fixtures.

1. Such as for example, at the time the construction of a house is going on, various sorts of components such as sheetrock, framing materials, flooring materials, concrete, bricks, wiring, lighting fixtures, as well as kitchen as well as bathroom fixtures are going to be needed.

2. Denote the measurement unit with respect to each of the materials. Moreover, it might be a standard unit. Moreover, for example, the liters or gallons are going to be the unit of measurement with respect to the paint that is comprised in the list of materials.

3. Once the needed materials are determined, enter them in on the spreadsheet. Moreover, for example, if paint is required for the project, enter "green paint" beside item #1. Furthermore, in the column with respect to unit of measurement, the "gallons." must be mentioned. Afterwards, specify the needed number of gallons in the quantity column.

4. With respect to waste, 15 – 20 % must be considered for material computations.

Divide the Project Into Particular Categories or Sections

Since various sections of the project are administered by various contractors or subcontractors, separate the list of materials into these sections. Like this, every contractor or subcontractor can determine the accurate project cost.

1. At the time of building a house, there’re various sections such as "plumbing", "framing", "kitchen", "electrical", "flooring” as well as "bath".

2. Certain materials might fall under greater than 1 section. Furthermore, for example, in case there’re "flooring” as well as "framing", the same nails must be used for two of them. Therefore, it is vital to divide the total number of nails that is calculated between the 2.

Calculate the Labor Needed to Finish Every Section

For the quantity of work to be done, determine the count of hours of work or man-hours needed for completing. It must be a careful estimate since certain workers are proficient in comparison to others.

1. Have an indication from the contractors concerning total number of hours that are going to be needed to finish a specific portion. A quantity surveyor can simply calculate that as per their proficiency with associated projects.

Make the Initial Cost Estimate as per the Architect's Design Search the average prices with respect to the materials as well as labor in the region across various hardware stores. In order to have an indication regarding labor prices, discuss with the contractors in the region who manage the similar projects.

Through including labor costs as well as material prices, one can have an accurate picture of the amount going to be needed to complete the project.

Get a print of the separate copy of the BoQ for primary or first cost estimate. Generally, that info isn’t specified on the official bill of quantities that is provided to contractors regarding bids. Furthermore, it must be utilized to compare bids gotten from contractors to determine the optimum bid for the project.

Prepare a Schedule according to the Estimates in the BoQ

Once labor estimates are obtained, one can see how much time will be needed to complete the project.

1. Furthermore, for example, in case it is assessed that one thousand man-hours are going to be needed to construct the house, say the contractors work forty hours weekly and there’re no breaks, it would need twenty five weeks to build the house. On the other hand, to contemplate interruptions, assuming it to take thirty to forty weeks.
