Tips for concrete estimation

Estimating concrete reinforcing costs is a vital phase of a construction. For ascertaining this keep in mind that the reinforcing steel supplier has taken account of all accessories, cutting, bending, and allowances for lapping, splicing, and waste. When no lap specifications are mentioned add 10% to your quantities for lapping, splices, and waste. Also consider 10% waste for welded wire fabric.

Consider the labor unit price for the subdivision of Reinforcing to put in accessories like bean and slab bolsters, high chairs, bar ties and tie wire

Besides checking structural drawings and architectural drawing, also take into consideration the mechanical and electrical drawings for equipment pads and grouting requirements on steel drawings

Deduct small (two square feet or so) while making estimation of the concrete quantities for floor slabs or walls.

One can avail the concrete prices from suppliers near the job site. A volume discount is obtainable which depends on the competition in the area. Don’t forget to add for waste on the whole for slabs and footings on grade.

In the case of compression testing for a project consider a least amount of one test per pour on smaller pours and a smallest amount of one test for each fifty yards of concrete placed. Each test should comprise of a minimum set of three cylinders.

For structural concrete estimation, includes the requisites for concrete additives, curing methods and surface treatments. Also give consideration to climate conditions alongwith hot or cold weather conditions, prerequisites for concrete placing and finishing methods and equipment.

For estimating precisely the components like formwork, reinforcing steel, ready-mix concrete, placement of the concrete mix, finishing of the surface, and curing should also be considered.


In order to finish the concrete surface a good rule of thumb for finishing concrete permits 1,000 S.F. of slab per each cement finisher.

Techniques of Construction Cost Estimate

Construction cost estimating associates evaluating materials, labor, overhead, subcontractors and equipment needed to complete a project. Estimates come in two forms: hard money and cost plus. Hard money approximate is the ultimate cost for a project. Cost plus is shaping the whole cost for all aspects of the project plus adding profit margins. It's important to balance giving an attractive estimate with being able to turn a profit on a project.

Estimating is the mainly significant of the realistic aspects of construction management, and the matter deserves the nearby attention of one aspiring to a career in the profession. It is a relatively easy subject to understand; however, as it brings one up against practical work, methods and system, knowledge of it cannot be acquired without close application.

Estimating Materials
From the approximate of a work it is potential to conclude what materials and in what quantities will be necessary for the work so that the arrangements to procure them can be made.

Labor
Labor is the largest expenditure on any construction work. When estimating, imagine a margin for overtime and also lost time because of difficult weather. Balance the cost of adequate labor to meet particular deadlines with fewer workers working extra overtime. Labor expenses comprise more than just the hourly wage. A single worker laboring through overtime might be less expensive than two workers laboring during regular hours.

Overhead
Overhead costs such as securing permits, deposits for utilities, job site insurance, connecting utilities, and extraneous expenses (security, framing, etc.) should also be factored in to the estimate. Some items, such as office operations or mandated workers' compensation payments, are considered the "cost of doing business," and it is up to the estimator to balance what to absorb and what to add to the estimate to ensure getting the job.

Estimating Subcontractors
Presently as the estimator is working for the client, subcontractors---plumbers, electricians, etc.---are working for the estimator. Receive all quotes with exact terms and deadlines. Insist on penalties for missed contract terms. When including subcontractors' costs in the final estimate, calculate reasonable markup for profit.

Job Site Equipment Rental
Construction estimating means bringing in equipment not always owned by the general contractor. Skid steers, forklifts, generators, pneumatic tools and compressors and power lifts are examples of rented equipment. Include in the estimate the time needed to complete the job plus a reasonable markup for profit.

Successful Estimating Attitude
Construction estimators walk a well row between trailing the work or receiving the job and not making sufficient money. A victorious estimator is positive, thorough and---most important---has the reliability to do both the company and the buyer right. Approach each estimate with the attitude of providing the best price to gratify everyone connected with the project.

Estimating Plant
An estimate will help in determining amount and kind of equipment needed to complete the work.

Estimating Time
The estimation of a job and the past experience allow one to estimate quite closely the length of time necessary to complete an item of work or the work as a whole.
Whereas the significance of knowing the probable cost requires no emphasis, estimating materials, labor, plant and time is immensely useful in planning and execution of any work.

A variety of Functions of cost estimate in construction push you to success

Now- a- days construction becomes that business field which is changing rapidly with the changes of the society. As the total civilization is changing across the world, the demands of people are almost changing with the necessity of present situation. Ultimately the total process of construction is changing itself. To accommodate with the new kind of changes an ideal businessman must concentrate on his project as well as his project cost. Otherwise he or she can not be able to make him or herself stand steadily in the construction business.

So to be a successful businessman you must aware of the importance as well as the functions of the cost estimate in construction

Estimate Project Costs:
To determine the total cost of the project is the main function of cost estimating in construction. To estimate the individual costs of each major component of the project is the second stage of cost estimation. Even when the construction planning begins the project-wide estimate is often done before it. It is one of the vital determining factors in the final cost estimating process.

The factors behind the estimation:
The estimates for the individual parts of the project get underway once the total project budget is established. The estimates for the project depends on all the materials, labor, equipment and subcontractor costs. Such other general conditions like permit costs, temporary office costs, and utility and insurance costs also work as the “factors” behind the estimation.

Developing Materials List:
Materials keep an important part in estimating the cost of the whole project. If the list of materials becomes long, the cost of the project automatically becomes high. In that case the estimation will be done based on the high cost of the project. So an estimator must be careful about the list of the materials as it is an essential part of determining the cost of the whole project before the construction starts at all.
Some materials in a project must be looked at more critically during estimating because slight differences in their features can make big differences in their costs. And individual cost difference makes a great effect on total cost of the project as we have already discussed before.

Specify Equipment Needs:
Equipment to move materials, people and earth must be included in the final project estimate. As the estimators consider how the work will get done, they have to think about what equipment & what kind of equipment will be necessary; as the cost depends on the quality & quantity of the equipments. Estimators have to decide if certain equipment will be hired, or if there is contractor-owned equipment that will do the job. The required equipment must be specified on the project schedule for hiring, and in the case of owned equipment the equipment managers will be notified so that the hiring cost will be saved as well as the estimation will not reach at so high.

Simply, we can say estimation is just like a budget. If we can maintain our budget we will definitely save certain money for our future as we have already decided while do the budget. Similarly, if we can estimate the cost of a project properly we will definitely make a good profit which we may utilize in another project. On the contrary, if we can not we must have to face a big failure. So we must aware of the functions of cost estimate in construction to meet the success.
