Mistakes When Making Estimates That Can Be Avoided
In the last three years, only 31% of all projects have exceeded the budget by less than 10%. Moreover, 78% of engineering and construction companies believe that the risks of projects from year to year only continue to increase. In short, there is something to work on.
Here are five mistakes in determining the estimated costs you need to know, as well as some helpful tips on how not to fall victim to another miscalculation.
- Unrealistic Expectations
Don't let optimistic (or pessimistic) expectations affect your calculation. Relying on the ideal or most critical scenario, you can get a biased and completely unrealistic estimate. Agree, the last thing you need is a completely broken deadline or inflated expectations.
- All Eggs In One Basket
Trust your knowledge and experience, but do not be lazy to consult with third-party sources. An accurate estimate should be a common fruit of your own knowledge and independent forecasts of the estimates of estimated construction prices. This will complement the data based on personal experience, independent and unbiased assessment.
- Lack of Necessary Permits
Permits cost money. And if you do not have them or you did not get what you should have, you risk slowing down the whole process from the word "absolutely". When entering a new market or performing a new type of work for you, make sure that the necessary permits and corresponding prices are included in a separate article. This will save you from unpleasant surprises
- Designing "In Vacuum"
All project parameters must be determined at the earliest stage. You do not want to get a project in which the third floor of your house is designed as many as three bathrooms, although the budget is set for only two (or worse, in your budget, the third floor is not provided at all!). Understanding the limitations and limits ensures that all project participants work on the same project, and no additional adjustments need to be made.
- Omitting Details
No matter, due to temporary or limitations, weak or knowledge or unintentional errors, omitted details or described too generalized TK will sooner or later lead to undesirable consequences. Obviously, your initial calculation will be too low, which will lead to inevitable adjustments and delays. Since this is one of the most common mistakes, it will not be superfluous to sit down and compare all the materials, labor and equipment, referring to the already implemented similar projects and estimates.
In order for a construction project to be successfully implemented, the scope of work must be determined accurately and completely. In turn, this means that you need to collect and analyze a lot of information.
Data Collection: Where to Get Information?
- Plans and Specifications
Plans and specifications for already implemented similar buildings and structures should be the main source of information to determine the scope of your next project. These documents (which must contain data on the scope of work) are a treasure trove of information containing drawings, materials and products used, installation methods and quality of work. Plans and specifications are very helpful in drawing up the terms of reference for the design.
- Executive Documentation
Unexpected things happen on the construction site, and contractors have to deviate from time to time, even from the most thoughtful drawings and specifications. Examining the enforcement documentation can explain why the deviations occurred and how they were expressed, so that you can prepare for the changes or, better yet, prevent them.
- Construction site inspection
In any case, there is nothing better than going to the construction site of any object in person. A visit to the facility can show possible problems in the supply of equipment and materials, in the conditions and operation of the existing facility and even demonstrate potential security issues. Going through the territory, you will find that you can directly see the mistakes of others, so as not to make them on your object
- Suppliers
When compiling the scope of work is often advised to learn to think like a contractor, so why not consult with any of them? These professionals have extensive experience and see projects through the prism of this experience. Their knowledge is guaranteed to help make a more useful and complete statement of the scope of work.
The work horizon sets the tone for the whole project, so no pitfall should go unnoticed and no question should go unanswered. There is no such thing as an excess of information.
