Steps of a proper Estimation

A proper estimation is integrity of some sequential processes or steps. An accurate estimation gives you the chance to complete the project in schedule time and under budget. The basic understanding of the project estimation gives you some advantage which will be surely beneficial for you. That’s why it is very important to follow the steps of the project estimation properly. Here we will discuss the steps of a proper estimation.

The Design: First of all you have to study the design accurately. Only a clear understanding will give you a better idea about how the project is going to be after completion. The drawing and supporting electronic files are included to illustrate the general scope of improvements. You will take care of the essential factor of the construction like safety, traffic operations, durability, desired appearance, maintainability, environmental protection, drainage and other permitted constraints. The design review process is much more important because the success of the project is on the design.

The Required Software: Selecting the proper software required for the estimating a project is another important step for the project estimation. To find out the perfect software for the type of estimation is very important.

Taking out quantities: In the next step of taking out quantities, the measurements are taken off from the drawings and entered on measurement sheet or dimension paper. The measurements to be taken out would depend upon the unit of measurement. For example, in the case of stone masonry in superstructure, length, thickness and height of the walls above plinth level would be taken out from the drawings and entered on the measurement sheet, whereas, in the case of plastering only the lengths and heights of the walls would be entered. Obviously, the unit of measurement in the first case is cubic meter and that in the second case is square meter.

Squaring out: The fourth step consists of working out volumes, areas, etc. and casting up their total in recognized units.

Abstracting: In the last step all the items along with the net results obtained in the second step are transferred from measurement sheets to specially ruled sheets having rate column ready for pricing.

The last two steps above are known as working up. All calculations in these stages and every entry transferred should be checked by another person to ensure that no mathematical or copying error occurs

The Prospect of Project Estimating in the year 2011

In anticipation of contractors’ needs in the year ahead, technology providers are continuing to offer new products and integrations for the construction industry. One key area that will likely still remain a top priority in the year ahead is estimating efficiencies.

Estimating is important right now for a number of reasons. Primarily, in today’s competitive market environment, construction companies need to come in with low bids while still maintaining good margins to remain profitable. Estimating and takeoff technology can help.

In smaller firms, the roles of estimator and field superintendent are usually both done by the owner of a company. In fact, it is the ability of the accomplished tradesman to estimate that allows him to take the step from employee to owner of his own business. His success hinges completely on how good his judgement and objectivity is in estimating.

For the large firm, the estimator may be a partner or an employee -- even, one of several, on a team of estimators. The firm relies on an estimator to provide all the information to determine if a particular project is suitable to bid on.

Apart from the personal efficiency, the construction companies are looking at technology to become more efficient, technology providers continue to release new products and integrations. For example, On Center Software, www.oncenter.com, The Woodlands, Texas, and Benchmark Estimating, www.benchmarkestimating.com, Manchester, U.K., announced a new custom integration.

This means construction companies will be able to import takeoff data from On Center’s On-Screen Takeoff into Benchmark Estimating software. The integration is currently in development, but will ultimately save a significant amount of time in the takeoff process, while also increasing accuracy.

According to Angelo Castelli, director of business development, On Center Software, the integration will provide a new level of productivity and efficiency for estimators, and the flexibility of the systems will be advantageous for project managers.

Rob MacDonald, director, Benchmark, says many of its clients have been inquiring about digital takeoff solutions, and this integration will provide them with the solution they want.

This is just one example of new estimating-technology integrations for contractors in the year ahead. Keep your eyes open for new products and partnerships, as 2011 is going to be a big year for improved efficiencies in the industry

The Industrial risk of Cost Estimation in the Bidding Process

Project cost estimation in the bidding process is a critical concern for the competitiveness and profitability of an engineering and contracting company. Estimates which diverge as little as possible from actual costs have to be made on the basis of relatively limited information. Of the macro-items contributing to the overall cost of a plant project, those
linked to engineering activities have been growing continuously in percentage terms for a number of years and have thus become the object of considerable interest. Moreover, since these items are difficult to standardize, estimation is particularly difficult. A method able to produce reliable estimates for these activities could certainly be usefully transferred to other project stages. The methodology proposed to formulate a bid estimate for a HAZOP study envisages the joint use of three tools to produce more accurate estimates and improve the quality of decisions through explicit assessment of the risk of over-estimating (or under-estimating) the cost.

First, an analytical estimation model based on improved structuring of available information provides more accurate estimates and facilitates the use of IT applications. Second, company knowledge gained in previous projects is structured and maintained in order to ensure continuous improvement in estimation. This information can be used to improve over time the understanding of the determinant values in the model itself, so obtaining increasingly accurate estimates and probability distributions which take account of historical errors. Finally, a simulation technique provides the probability distribution of the overall cost and thus the confidence interval of the estimates.

Project cost estimation in the bidding process is a critical concern for the competitiveness and profitability of an engineering and contracting company as it involves considerable risk. Indeed, with only the limited information available in the tender documents and the partial results of the basic engineering, an estimate must be drawn up which varies as little as possible from the effectively sustained costs. The reason for this is that the industrial goods market is becoming increasingly competitive and the typical contract is now the lump-sum, in which the contractor agrees to supply at a pre-determined price. Since the starting point for this price is the estimate prepared during the bidding, it is evident that this cost estimate is crucial to the competitiveness and profitability of engineering and contracting companies.

That’s why project cost estimation is always a critical process on the part of the engineers. The estimator must have to take great care in the estimating process to deliver an accurate calculation.

Tips for a perfect estimation

Always just before to start a project some questions crawling in the minds of every member of the Architects, Engineers and Construction industry. How much will it cost? How many days will it take to finish? What will be the profit margin of the project? To get answers of all these questions you should seek the help of project estimation.

Any construction projects typically involve many dynamic aspects, yet they're often constrained by finite conditions. These contradictory forces make it very difficult to determine with pinpoint accuracy the time and effort required. By using a set of proactive estimating techniques to scope, plan, and constrain your project conditions, you can dramatically improve your estimating practices, reduce and mitigate risks, and increase your project success rate.

Do you excel at predicting the time, funding, and resources your projects will require? Whether your company aims to develop a new product or service, update an existing system, or launch a new Web site, these undertakings will require people, schedules, funding, resources, requirements, testing, revising, implementation, evaluation, and many other elements. Sometimes we forget the hidden or unknown variables that are difficult or impossible to anticipate and sometime even more difficult to resolve.

That’s why you need to be more careful when estimating for a construction project. Here we are discussing about some important tips for perfect project estimation.

1. Maintain an ongoing "actual hours" database of the recorded time spent on each aspect of your construction projects. Use the data to help estimate future projects and identify the historically accurate buffer time needed to realistically perform the work.

2. Create and use planning documents, such as specifications and project plans.

3. Perform a detailed task analysis of the work to be performed.

4. Use a "complexity factor" as a multiplier to determine whether a pending project is more or less complex than a previous one.

5. Use more than one method to arrive at an estimate, and look for a midpoint among all of them.

6. Identify a set of caveats, constraints, and assumptions to accompany your calculations, which would bind the conditions under which your estimates would be meaningful. (Anything that occurs outside of those constraints would be considered out of scope).

7. If the proposed budget or schedule seems inadequate to do the work, propose adjusting upward or downward one or more of the four project scoping criteria: cost, schedule, quality, and features.

8. Consider simpler or more efficient ways to organize and perform the work.

9. Plan and estimate the project rollout from the very beginning so that the rollout won't become a chaotic scramble at the end. For instance, you could propose using a minimally disruptive approach, such as a pilot program or a phased implementation.

10. In really nebulous situations, consider a phase-based approach, where the first phase focuses primarily on requirements gathering and estimating.

11. Develop contingency plans by prioritizing the deliverables right from the start into "must-have" and "nice-to-have" categories.

12. Refer to your lessons-learned database for "20:20 foresight" on new projects, and incorporate your best practices into future estimates.

In conclusion, by using a set of proactive estimating techniques to scope, plan, and constrain your project conditions, you can dramatically improve your estimating practices, reduce and mitigate risks, and greatly increase your project success rate!
