Whether you are a property owner or a contractor, you want to have a clear and accurate forecast of how much a building project will cost and how long it will take before you begin.
We will also look at the major types of construction contracts , best practices , pitfalls for estimators , the use of historical data, and estimation software. Construction cost estimating is the process of forecasting the cost of building a physical structure.
Of course, builders and clients both worry about the financial impact of cost overruns and failing to complete a project. Clients considering large projects often seek multiple cost estimates, including those prepared by contractors and those calculated by independent estimators. Contractors use them when deciding whether to bid on a project. You usually prepare estimates with the input of architects and engineers to ensure that a project meets financial feasibility and scope requirements.
A good cost estimate prevents the builder from losing money and helps the customer avoid overpaying. Creating a construction cost estimate is good practice for anyone who cares about how much their project will cost. You routinely do cost estimates for all kinds of construction projects, from building new structures to remodeling. Accurate estimates are especially critical for development projects, which have budgets and timelines closely linked to paying back lenders and generating revenue as early as possible.
They are also essential for large civil projects or mega-projects because of their sizable scope and the potential involvement of public money. On a mega-project, small miscalculations become magnified. In projects constructed with public funds, cost estimates increase accountability, provide transparency, and enhance trust in your ability to manage the project properly.
Failing to prepare a reliable cost estimate can have disastrous results. One notorious example was the Marble Hill nuclear power plant in Indiana. The owner abandoned construction in , seven years after it began. Estimating the cost of any project with absolute precision is impossible, and projects can fail for unforeseen reasons.
But a skilled estimator will account for as many factors as necessary — including such things as market conditions — to create an accurate estimate.
The accuracy of a cost estimate relies on a number of things: the quality of the project plan; the level to which the estimator defines a project; the experience and skill of the estimator; the accuracy of cost information; and the quality of any tools and procedures the estimator uses. Depending on the type and size of a project, as well as the industry, cost estimation may fall to one individual or a team, and estimators may hold a number of different positions.
For some construction projects, contractors and subcontractors prepare the cost estimates, though this is not regarded as best practice. At other times, the construction salesperson will be responsible for creating an estimate. For contractors, good cost estimates win jobs.
Customers usually select the lowest bid that meets the standards and specifications they set. In a competitive bidding situation, the time and effort you spend preparing the estimate are a cost of doing business and an investment in winning the job. If urgency is a factor for a project, the speed at which you prepare a bid can also be a differentiator.

Understanding cost estimation requires you to have a basic grasp of the construction process. Here are the nine basic phases of a building project:. It begins early in the construction process and can last until up to a year of occupancy or use.
A commissioning provider carries out commissioning, usually a firm with experience in commissioning buildings that serve particular functions. Determining Requirements : The first real step in constructing a project is a pre-design phase or planning phase. Forming a Design Team: The project owner contracts with an architect who will then select other specialized consultants to form a design team. Complex projects and projects which require meeting specific design requirements — such as acoustics or housing hazardous materials — will have more specialized consultants on board to ensure the design meets requirements.
The architect is generally responsible for overseeing and coordinating the design process, though for some projects such as industrial construction , an engineer may be one of the people overseeing design. Designing the Structure : This step deals with the architect creating a series of designs. Designing thus progresses from a schematic design phase, when the architect presents a high-level design to the owner for approval, to a design development phase, when the architect works with the design consultants to decide on specifics of the construction design.
The last step is the construction documents phase, i. The specifications, which various participants in the construction process read, appear in a standard format called the MasterFormat , which the Construction Specifications Institute developed. Estimators produce and revise cost estimates for the project as the architect fleshes out the design. Bidding Based on the Scope of Work: Once the construction documents are finalized, they are released to contractors who wish to bid on the project.
Along with these bidding documents, they include instructions on how to submit bids, a sample of the contract agreement, and financial and technical requirements for contractors. These documents, which effectively define the scope of the work, are the basis on which contractors prepare their estimates.
For more on how to develop a statement of work, consult this guide. To ensure fair bidding, all contractors receive the same information, and the project owner usually selects the lowest qualified bidder. This bid tabulation template can help you compile your estimate. Excel Smartsheet. Signing the Contract: Once the contractor has been selected, they execute a set of contract documents with the owner. The contract documents encompass the bidding documents, which now function as a legal contract between owner and contractor.
Contracts can follow a number of models, depending on how complete the construction design is and how the owner and contractor bear risks. A unit price contract allows for more flexibility in design by having the owner pay the contractor per number of units they build.
A cost-plus contract, signed when the design is incomplete, has the owner pay for all costs plus a predetermined fee for the contractor. A variation of this is cost plus a fee with a guaranteed maximum. Construction : During the construction phase, the contractor oversees building in accordance with the construction documents.
A general contractor will hire specialized subcontractors for different sets of construction tasks, such as plumbing or foundation work. Throughout the construction process, the contractor engages in careful cost control, comparing actual expenditure with forecasted expenditure at multiple points in the construction process.
Cost control ensures that the contractor is actually able to turn a profit. This budget template can help you compare actual costs to estimated costs.
Close-Out: When the builder comes close to finishing a structure, the contractor requests the architect perform a substantial completion inspection in which the architect verifies the near-complete status of the project.
At this stage, the contractor provides the architect with a document called the punch list, which lists any incomplete work or needed corrections. After the architect inspects the structure, they will add any additional incomplete items to the punch list.
Completion: After the contractor completes all the incomplete work detailed on the punch list, the architect performs a final inspection.
If the contractor has completed the structure according to construction drawings and specifications, the architect will issue a certificate of final completion, and the contractor is entitled to receive the full payment. An alternative method of project delivery is the design-build process, which integrates building design and building construction. Instead of contracting first with a design team and then with a contractor, the owner contracts with a design-build firm, which handles both functions.
The main strength of this approach is greater alignment and coordination between design and construction and a reduction of construction missteps.
Accountability rests with a single party, which owners may appreciate. It can also save time and increase efficiency, and design-build processes are likely to be significantly cheaper than conventional design-bid-construct processes like the one detailed above. The American Society of Professional Estimators classifies estimates according to a five-level system that becomes increasingly more detailed and reliable.
Construction cost estimating has a lot in common with cost estimating for other types of projects, and you can read more about key concepts and tips in this article. A simpler system of classifying estimates features just three primary categories: design estimates, bid estimates, and control estimates. These category names reflect the way in which you use the estimates. Creating a cost estimate for a project as complicated as a building calls for a systematic way of enumerating costs.
To simplify the process, cost estimators may use the Uniformat system of viewing a building as a set of seven functional divisions. These are:. The RSMeans Square Foot Costs Book , which compiles building cost data according to these divisions, is a widely used resource for developing cost estimates based on costs per square foot.
Contractors who are bidding for a job will create a document called the bill of quantities, which is an itemized list of the work and materials required for a construction project. This is a crucial step in determining the cost of the work before bidding. Creating a bill of quantities is a four-step process that used to be done painstakingly by hand on paper and is now usually done with spreadsheets or specialized software.
So what information do estimators use to create an estimate? In fact, so many factors can influence these costs, that cost estimators recognize that every project is unique. One of the primary factors that influences cost is the building site.
Waterlogged soils, previous construction, geological formations and the nature of the rock, native animal species, and the presence of historical or natural heritage sites are just a few of the things that can affect materials and labor requirements, delay the issuance of permits, and increase the time needed to complete the project.
Similarly, the location of the construction site relative to economic centers can also be significant. Contractors may have to transport workers and materials for a long distance if the site is remote.
In a bustling urban area, the wages may be higher. Furthermore, regulatory requirements may be stricter, and hence more expensive to fulfill or comply with, at some construction sites than at others. Lastly, certain construction sites require the completion of feasibility or impact studies, which are likely to prove expensive. Time-related aspects can also affect costs significantly.
Chief among these is the project schedule, as a compressed, labor-intensive schedule will incur higher costs and rush charges. Also, with a project that you expect to take years to complete, you will almost certainly have to consider fluctuating market conditions and inflation.
Finally, owners inviting bids may notice seasonal variations in bid amounts, since contractors are busier at some times of the year than at others. The size and complexity of the project are other major influences on cost estimates. Larger, more prestigious projects may attract more reputable contractors, or there may simply be few firms capable of handling the project. Either of these scenarios can escalate project costs. Construction documents that hint at imprecision will almost certainly result in higher bids from contractors who want to err on the side of safety.

From the time a construction project is proposed, and throughout its life, the estimate provides information that is critical to its success. If you are a student of construction or pursuing a career as a construction professional, you understand the need to create, organize, format,. The key to producing an accurate estimate lies in the organization of the information that will be used to determine the amount of material, labor, and equipment required for the project.

Software costs estimation is inherently difficult, and humans are terribly bad at predicting absolute outcomes. No two projects are the same; each is unique in what it sets out to achieve and unique in the myriad of parameters that form its existence. NOTE: You will require the services of a quantity surveyor for an accurate budget estimates preparation in the pre-contract stage and also cost control and planning during construction. District Cost Estimate.
It is processed of predicting the probable cost of the project by calculating material quantity and their costing with help of market rates before undertaking any construction project. Before you directly start calculating quantity, you must precisely and correctly read the construction drawing. Some dimensions you need to calculate from drawing also. For example, first quantity of estimation sheet is excavation in foundation. To find out the dimension of length, width and depth of excavation from drawing. Keep in mind:. Here, the Size of footing is 1 m x 1 m.

Сьюзан на какое-то время забыла про Хейла. Она молила Бога, чтобы Стратмору звонил Дэвид. Скажи мне скорей, что с ним все в порядке, - думала. - Скажи, что он нашел кольцо. Но коммандер поймал ее взгляд и нахмурился. Значит, это не Дэвид. Сьюзан почувствовала, что у нее перехватило дыхание.
Ш-ш-ш, - утешал он. - Это. Теперь все в порядке. Сьюзан не могла унять дрожь. - Ком… мандер, - задыхаясь, пробормотала она, сбитая с толку. - Я думала… я думала, что вы наверху… я слышала… - Успокойся, - прошептал .
- Вспомни арифметику, Сьюзан. Сьюзан посмотрела на Беккера, наблюдавшего за ней с экрана. Вспомнить арифметику.
- Этот шифр взломать невозможно. Сьюзан посмотрела на него и едва не рассмеялась. Невозможно. Что это должно означать.
Росио подошла к нему еще ближе. - Я не знаю, кто вы такой и чего хотите, но если вы немедленно отсюда не уйдете, я вызову службу безопасности отеля и настоящая полиция арестует вас за попытку выдать себя за полицейского офицера. Беккер знал, что Стратмор в пять минут вызволит его из тюрьмы, но понимал, что это дело надо завершить совершенно. Арест никак не вписывался в его планы.
Именно эта целеустремленность всегда изумляла, эта неколебимая верность принципам, стране, идеалам. Что бы ни случилось, коммандер Тревор Стратмор всегда будет надежным ориентиром в мире немыслимых решений. - Так ты со мной, Сьюзан? - спросил. Сьюзан улыбнулась: - Да, сэр.
