A bid process is required to award the most jobs in construction industry. In a bidding contest the lowest bidder will be awarded the contract. Estimating a construction bid involve some knowledge of the building process.
The bid estimate is specific to the project conditions illustrated in the plans and specifications. The bid estimate is required by contractors and subcontractors for bidding purposes or the owner to appraise bids.
In order to prepare an accurate construction bid, the most current drawings, project specifications and copies of any addenda or change bulletins that have been issued are required. The company who is calling for the bid should render all of these documents. In case the drawings are submitted from a plan room, the addenda and bidding requirements should be checked properly.
Review the drawing and floor plans. Then review the title and symbols pages for any general project requirements.
Review the project specifications for getting most sets of construction documents. Read the section related with your trade and read the prelim section featuring general project conditions.
Measure material quantity by executing a material takeoff. As for instance, an electrical contractor should take into consideration the receptacles, switches, junction boxes, light fixtures, and length of wires and conduits along with panels, transformers and any electrical connections for equipment or mechanical work. These estimates will sum up the total material price.
Work out the labor costs. Find out the time frame for completion of the job and multiply this number of hours with the average wage plus any labor burden to ascertain the total labor costs.
Put material and labor costs together and comprise any special fees like permits, wage scale, bonds, insurance premiums or other costs. Multiply the total dollar figure with an appropriate percentage to contain overhead and profit.
Finally prepare your bid form putting price, complete scope of work and the name of the project.
In case the project is different from typical designs, the contractor should evaluate the actual cost of construction by taking the actual construction procedures to be used and the related costs.

How to make cost estimation to Pour Concrete
In order to refinish a garage floor, make a garden pavement, build your own paver stones etc., one has to find out the estimated cost of pouring concrete before starting a new project
In order to figure out the cost one has to initially compute the length and width of the area to be paved with concrete. Then resolve the thickness of the concrete to obtain the total volume of required concrete. As for instance 4 inches of concrete will be required for making a 10-foot-by-2-foot walkway.
If you put the above figures in a Concrete Calculator then it will show that for making the 10-foot-by-2-foot walkway with 4 inches thickness 0.25 cubic yards of concrete will be required. One has to buy 23 40-lb. bags or 15 60-lb. bags of concrete for this.
If you hire a concrete delivery truck, you have to pay extra charges for pre-mixed concrete deliveries and labor time along with pre-mixed concrete price.
You also have to incur expenses for other materials like gravel substrate for placing below the concrete, sand and gravel for mixing with the concrete, rebar for holding up the concrete, a squeegee to spread it, a trowel to joint it and a wheelbarrow and spade to mix it. You'll also require pre-made concrete forms and a concrete release spray for easy elimination of the forms as soon as the concrete dries. As the concrete cures you must cover it with a plastic tarp.
You also have to take into consideration for ancillary materials from hardware’s store.
In case of applying bagged concrete, obtain the cost per bag then multiply by the number of bags for determining the total concrete cost.
Also count the cost of the supporting materials. Then include this either with the cost of the pre-mixed concrete or the bagged concrete. Finally the overall cost of your concrete job will be determined.
