Six Factors That Affect a Pre Tender Estimate

pre tender estimate

When it comes to a pre-tender estimate, it is not only the price of the project that matters, but the various factors that affect it. These factors include the design parameters, consultant, and the information group. Of the ten factors, six of them are from consultants. The presence of these factors indicates that they are the most important.

Engineer’s estimate

In order to be competitive, an Engineer’s pre tender estimate must meet certain requirements. An estimate must include the correct price for each unit of work. The Engineer’s unit price is the cornerstone of the estimate, and the process of establishing it requires engineering judgment. In order to arrive at an accurate estimate, an engineer must estimate the cost per unit of work and adjust it accordingly if there are any unforeseen circumstances.

The engineer’s pre-tender estimate must reflect an amount that the contracting agency considers acceptable and willing to pay for the contemplated work. Failure to meet this requirement may delay the project, or require additional funding to meet the contract cost. Over-estimating the cost can result in a waste of money, as it results in a higher price than the project is worth. The engineer’s estimate must also be based on market conditions, including the competitive bidding environment.

After a successful tender is selected, the contract is advertised. The winning contractor then receives the contract. The winning contractor then uses the agreement estimate as their bid price. This estimate must fall within the published cost range to secure the contract. If more than one conforming bid is received, the contract is awarded to the contractor.

Engineer’s pre-tender estimate is a crucial document used to manage project costs, schedule, and funding. Any changes to the costs must be incorporated into the estimate and communicated to management in a timely manner. The Engineer’s estimate should include all the work contemplated in the project. The estimate should also account for any changes in unit costs and must be updated as they occur.

The accuracy of an Engineer’s pre-tender estimate can be improved by identifying and evaluating low-visibility factors. The accuracy of a pre-tender estimate is affected by external factors such as the market conditions and the procurement forms. These factors are often ignored and should be addressed.

Before the estimating process, the client should identify the requirements and the materials that the project requires. Obtaining accurate information from suppliers and manufacturers of materials is also important. Without accurate information, the cost estimates will not be accurate. If the client does not know the exact specifications, an Engineer’s pre-tender estimate will not be accurate.

During the evaluation process, the Engineer’s Estimate report has seven different breakdown types. These include A+B Bidding, Construction Engineering, Preliminary Engineering, Right-of-Way, Utility, and Other. Each of these types will require a separate budget line. The amount needed to fund each breakdown will be listed in the Engineer’s Estimate report.

Unit bid prices

Unit bid prices for pre-tender estimates are an important part of a construction cost estimate. These prices are calculated per square foot or square metre. These are then multiplied by the total floor area to obtain a final estimate. Contractors must ensure that they are compiling accurate estimates that accurately reflect the costs of the project.

Pre-tender estimates should contain unit bid prices for each element of the contract. This helps in controlling costs and rates by the authority accepting the tender. This also helps in preventing an unworkable rated tender. As a result, the project can progress smoothly and timely. It is also an efficient way to manage costs and to avoid disputes.


Contingency is a factor that helps to control cost and estimate risks. The amount of contingency in a pre-tender estimate depends on the project’s complexity and the extent of uncertainty. Various methods can be used to determine the contingency. Some are simple, while others are complex and require statistical techniques.

A contingency budget lays out how much money will be set aside in case the project runs over budget. It should also detail the allocation of unspent funds among subcontractors and contractors. The contingency funds should be clearly defined and the contractor should clearly communicate how these funds will be spent.

The selection of the method to calculate the contingency depends on a number of factors, including the size and complexity of the project, available expertise and time. There are a variety of methods to determine the contingency for a project, but these are governed by a few general guidelines.

A contingency is a downside risk estimate that accounts for unknown risks and costs. It typically refers to costs, but may also include other aspects of a project. A contingency may be a part of a contingency plan, or it can be a component of a contingency plan that is used to mitigate the risks in a project.

The accuracy of a pre-tender estimate is critical to the project’s success. This estimating process requires the use of technical staff with proper project specifications. In addition, clients must ensure that the information obtained from suppliers and manufacturers is accurate. An incomplete understanding of the materials used for the project will negatively affect cost estimates.

A pre-tender estimate should be accurate and include an appropriate amount of contingency. An accurate estimate can help ensure that the contract is competitive and profitable. There are numerous variables that can affect a pre-tender estimate. For example, the type of contract will determine the amount of the contingency in the pre-tender estimate.

Construction costs are unpredictable, and contingency funds are essential for all projects. Construction firms often allocate 5 to 10 percent of the total budget to cover these costs. It is vital to carefully consider your risks when setting up a construction contingency budget. You can minimize your risks by communicating with your team and using detailed planning.
