Useful for any work, project, or personal venture. We have over 500 downloads in less than a month to celebrate we have the new version of price analysis unit and a new tool for calculating overhead or indirect costs. ESTIMATED PROJECT
Estimating the cost and effort will never be an exact value, too many human variables, technical, environment, policies that may affect the final cost. But the combination of good historical data and systematic techniques can improve the efficiency of the estimate. The estimate is an important activity that should not be undertaken carelessly and is based much more on the experience of the analyst in tables and yields. More precise estimates of a project are achieved by using real data comparisons and recent projects undertaken or completed that are similar or comparable to the work that we are quoting. smaller companies used cost estimation techniques and times, based on a series of systematic steps that provide estimates with acceptable risk. These are based on the simple decomposition of the project in measurable activities. By applying basic measures of productivity, obtained through experience and confirmed on several projects, allowing to determine inputs, equipment and project cost. This identification of resources for each activity, to estimate the cost of each activity. After determining the agenda of the project, which requires experience and access to good historical information. To build the final project cost estimates combine each of the activities and add missing activities. Project Planner has to estimate three things before the project begins: the last for, the effort required and how many people will be involved. Then the planner must predict the resources (material, equipment and adjust staffing) to be required and the risk involved. The application of the economic concept of the work depends on many factors difficult to assess the complexity in implementation, quality of materials and the supply of or demand for labor, especially the specialized, which can be scarce in one time. Building conditions are not always the same and depend on many factors. BUDGET
The budget is an estimate the cost of a project. The most accurate estimate of the cost of a work is produced by a budget based on unit prices. To do this you must take into account the division of activities, specifications, the test conditions and the needs assessed. The uncertainty in each but the variability in the returns to labor, we do not allow an accurate estimate of the total cost of a work. So when applying global budgets for completed work or per unit area and others intervened. The work will be reduced to basic unit prices to make an estimate as accurate as possible.
The budgeting is a task organized and must be done carefully, it is very easy to make errors, and omitted items, leaving out inputs, or neglect important costs. Ten budgets for work will get ten different values. BREAKDOWN OF ACTIVITIES
The project estimation is a way of solving problems and in most cases, the problem to be solved is too complex to be considered in a single part. For this reason, we decompose the problem, recharacterize as a set of small problems or activities that are easy to handle. by construction activities shall be specific tasks that are running the builder skilled labor in this work, and are part of a project that contains your: specification, scaling and enhancement. The activities consist of several essential inputs, in which each characterized by its own restriction. For example, an activity included in a canal project will vary depending on whether a channel in the plain, hillside or in the high mountains, therefore, should be added or removed construction supplies that make up the activity, and must accommodate construction efficiencies. There are simple and complex activities. The latter are composed of several simple activities. For example, the reinforced concrete as a composite activity, consists mainly of reinforcement mats, concrete and formwork which are simple activities.
To begin any analysis, we start by separating the project into small activities, then each of these activities are broken down again, reaching an appropriate level. This process facilitates the total cost estimate. With a little experience, it is easy to see how separate parts of a project.
We must achieve a level of detail where each activity can be independent of the other, either by the resources employed, or manpower, or equipment used. Since resources are managed are not quantified only by quantity but quality and performance. Each activity must be quantified (cubed) independently.
Considering a proper work breakdown, identifying the unit costs and making a good estimate of the amounts of each (through takeoffs and needs analysis), we can reduce the unexpected. CU
Project activities are measured in number of units and we fully define the size of the project. This will be the basis of our proposal, and must be precise and accurate. Correspond to the face of the company and is the vision we have of the client, and used for comparison with the other proposals. should be as precise possible formats and made tidy. I always thought the planes from left to right and from top to bottom, putting numbers on the key elements and naming all the elements based on the axes defined in the flat, horizontal and vertical, making it possible to reconstruct the data quickly in case of doubt for lack of an item, or if the item is repeated at other levels. The scaling should be detailed and structured. To have a specific proposal, we have all levels and contributions of each of the inputs of the work, otherwise, only increase the uncertainty in the work, and we must increase our share of contingencies. Together with the takeoffs we have very clearly what should be included in takeoffs and part of the project, and that parties must keep out of it, not part of what we contribute. Itemized
The base is the quote, and corresponds to the list of activities with the number of units of work, which is multiplied by the unit price obtained by the analysis of unit price for the activity.
This document is provided as the basis of the budget and the basis of the evaluation and control of the work.
HOW TO BUILD A BUDGET
To build the budget, join the itemized, which corresponds to direct costs, indirect costs, which should always include overheads, VAT, as appropriate to the listed company, and the expected utility to the type of work. VAT
Generally materials are considered without VAT, and charged state tax payment, but should be considered tax bills and we can not discount as part of the business.
