Whether you are preparing a budget of competitive construction project bidding, or simply be trying to calculate costs for construction work, remodeling or repair work you want to do, follow the steps below to ensure that labor costs are accurate and construction budgets are organized and complete.
Before you begin, review all plans and specifications and consider whether you will need the kitchen remodel ideas services of suppliers or contractors to perform the task. If that’s the case, let them get the information they need to quote your building or remodeling job ASAP. They usually wait until the last minute results in the quote is not accurate.
In order to ensure you have enough time to receive and review the prices of their suppliers and subcontractors, set a deadline for quotes, which at least is one day before the expiration date of the tender. Ask the suppliers and subcontractors to make their proposals in writing and in detail. If time does not permit, take detailed notes of bids be given by telephone.
If possible, get at least three estimates. Estimates of work of subcontractors typically cover a considerable price range and if has three estimates for each job, you can make a better informed about the number that should be used in their construction budgets decision. As you progress the quoting process, ensure that its subcontractors receive any updates or revisions to do.
Once you have the estimated power, make a comparison sheet and list major items should include subcontractors. Often, contractors have estimates on the same work include different elements in their proposals. Use the comparison sheet as a guide to review and compare the quotes you receive. Add money to the proposal of a contractor for something that it has been included and others excluded.
Provide a summary of estimates for all costs and tenders. Divide all costs into three basic categories:
The costs of construction materials include all materials, labor, equipment, etc., needed to build a building (eg, foundations, windows, roof).
The costs unrelated to the construction or remodeling, also called cost of general conditions or general direct costs include all materials, equipment and costs directly attributable to the completion of the work, but which are not real part of it (eg , temporary sanitation, garbage containers, monitoring costs, the cost of electricity for the project).
The general indirect costs include other costs necessary to maintain its business, which are not directly attributable to the project (eg, rent, telephone, electricity office). Identify and quantify these costs and then increase your rate of labor per hour to cover or add a budget to your construction budget for each project is calculated.
The costs of general conditions (non-production) may include 20 or 30 budget items, depending on the complexity of the project. Develop a summary sheet and list the various costs and games provided. Many of these are directly related to the time it takes to perform each task, so you should have an idea of ??the duration of the project. For example, if estimated need two temporary health services a week, you should know how many weeks will be used to determine the total cost.
Once you have the cost of building materials and general conditions, determine the subtotal. Your earnings, general overhead and insurance costs are usually calculated as a percentage of the aggregate. Combine these costs with subtotal and get the full estimated cost.
Now calculate the cost of labor
Before any deduction amount planes read the written specifications. Often the specifications manual includes special requirements or major differences and should record them before proceeding.
When you start to review the plans to determine the amount of building materials and workers needed to do the job, these tips will help you stay organized:
First, check all planes to get an idea of ??what the job required.
When making your itemized deductions, use markers or crayons to mark the plans. This allows you to know when you have included something.
There are many ways to get the quantities you will need to prepare the estimates. Some contractors use software programs, many use special forms of business and others have created their own forms. In any of these to use, enter the number of the sheet plane in the article. It has four objectives:
If you calculate the quantities of all materials first, it is easier to go back to allocate labor costs if you know what was the detail that was considering. Installing a wood floor level of a 2 × 4 around a window opening requires much less work than a 40 feet in the air under an overhang.
When the project is under construction, you can compare more accurately the actual costs of materials and fieldwork. If the job appears in a lump sum at their estimated it will be impossible to determine where and where calculated at least more.
When calculating the amounts sure you know what is the scale used in the drawings and details. Check the level with other flat sheets; sometimes the wrong scale scores architect on the plans. If you think you are seeing scale drawings ¼ and really are 3/16, their amounts will be wrong and this will significantly influence the costs of labor and materials.
Once you have calculated the amounts of building materials, add an appropriate amount for the waste material. Next, determine the cost of materials and labor to install them, as well as other costs related equipment.
Contact your service provider for information about materials for construction needs and, if not give a price for the total amount, check the prices per unit and determine the total cost of materials. For example, you need 434 feet of wood 2 × 4 pressure treated. Your supplier sells this material stretches 16 feet long, at $ 15 each. Divide 434 linear feet between 16 feet and round it to the next whole piece. In this case, you would need 2 × 28 4 to 16 feet long, for a total of $ 420. Do not forget things like screws, glue, sales taxes, charges for delivery and other incidental costs. Once calculated the costs of materials, appropriate to calculate the costs of labor.
Calculate the cost of labor requires experience. Focus first on the major budget items, since an error in them can result in a big difference in the total estimated costs. Depending on the amount of materials, try to determine the production rate. For example, your project has a wooden base of 1,250 linear feet. Calculate your carpenter can measure, cut and install 20 feet per hour basis.
Divide 1,250 feet between 20 to determine which need 63 hours. Remember that someone downloaded the material and distribute it to the various sections of the project. This also takes time, so please add this extra at times that estimated time to install the base.
Multiply the hours by the hourly rate. Hourly rates vary widely but the basics are the gross wage per hour, plus benefits, and state and local taxes. Many contractors add value to the hourly rate to cover part of their general overhead costs. Once you have the total hours for each budget item, total the hours and multiply them for the costs of labor.
The next thing to be considered for all construction budgets are the costs of construction equipment. Need to buy or rent a scaffold or maybe an elevated basket motorized? Again, time is a factor. Determine how long you will need the computer to calculate the correct cost.
After completing the costs of materials, labor and equipment, for the same total for that section of the estimate. The goal is to include everything in a format that you can continue later kitchen remodeling installation , or used in future estimates for comparison.
Finally, send check your math on the leaves of deductions for labor and materials, and prepare its bid.
If you were bidding documents …
When you receive the tender documents, make sure you have everything you need, including the instructions to tenderers, drawings, specifications, any attachments that may have been issued, and the geotechnical report, if necessary underground work .
Confirm the date and time of the tender, to be on time. Look for dates and times of all mandatory inspections, not ignore them. Check who should pay the permit, if a bond payment / performance or bid bond is required, and if the contract requires special insurance or payment of liquidated damages.
Find out when it is scheduled for the beginning of the work and if any overtime work is required. This will help you determine whether your estimate should include costs for special winter conditions.
If you have a tender form, check to see the data requested. Often the request form unit prices, the costs of alternative tender or other costs or expenses to be determined. Fill in advance all sections of the tender form can.
Try to calculate the duration of the project. Most bid forms require you say how much you think it will take the completion of the work, as many other costs related to the time required.
The day of the award, make sure you have followed the instructions required, such as the number of copies of the same shall be submitted, if necessary that the envelopes are sealed, etc. And finally, make sure to know where the bidding is going and give yourself enough time to reach your destination time. Do not forget to take into account the traffic to ensure that arrive on time.
