Construction Cost Roadmaps The project manager, assisted by the construction accountant, prepares a schedule with detailed cash flow estimates based on the final construction plan. Click on a document name below to download it. This also has the advantage of being a specific operation which has no requirement to commit to additional costs later on. Even the smallest changes to design and scope can lead to drastic cost changes due to having to rework a completed portion of the project. There are no legislative codes or mandated standards applicable to the cost engineering or cost estimating profession. It would seem reasonable to assume that masonry construction in the border states, with the amazing amount of readily available skilled labor, will cost less than masonry construction somewhere in non-border states.
This guide will be confined to cost estimating in the building construction industry. Managing cost sits at the top of project management criteria, along with managing scope, time and quality. The Outline Cost Plan is a key cost document that informs Project Review 3. We will prepare an initial budget cost which is established by reference to cost data from previous projects. Issues with Cost Planning The cost planning method is used mostly for public projects. It is prepared to develop a project budget and is based on historical information with adjustments made for specific project conditions. The use of computer-based technology and automation also provides opportunities for increased productivity in the process.
State quantities and costs for all material, labor, equipment, and subcontract items of work. For both public and private projects, the method is useful only in the early stages of defining the construction project. The beauty of our time is that the processes above can be easily managed with the cutting edge tools that technology nowadays enables us to use. Determine the level of competence and quality of performance. Determine amounts for performance bonding, profits, escalation, and contingencies.
Define amount for overhead, profit, taxes, and bond. This involves predicting when along the project schedule costs will actually be incurred and paid. A functional unit may be bedroom in a hotel, the cost per student for a school or cost per bed for hospitals. Finally, you will agree that, cost management must be seen as a process and its implementation requires innovation, automation, learning, involvement and commitment from people. We use a structural engineer on every project we design, partly because we carry professional insurance that requires it but a structural engineer will design a foundation specifically to the soil conditions on your site.
The documentation must be clear and logical or it will be of little value to the reader. Elemental cost planning is often referred to as 'designing to a cost' or 'target cost planning' since a cost limit is fixed for the scheme and the architect must then prepare a design not to exceed this cost. Some project cost models may use a cost per square foot, based on historical costs for other projects. Detailed Estimates Once final plans are submitted, the construction manager and accountant should review the plans and make detailed estimates for labor, materials and construction overhead. The Level 3 estimate provides a greater amount of accuracy, made possible by better defined and detailed design documentation. Materials taken from other sources are acknowledged in footnotes, tables or figures.
The forecast cost must be subjected to constructive scrutiny and justified progressively to senior management to ensure their confidence in the plans of the delivery team. Is it fixed lump sum, target sum, open book, or other? Investigate the past performance records of subcontractors submitting bids. The best plans are plans made with the finished construction in mind. The resources included must be linked to the current programme to ensure sufficiency with the work activities, along with a sensible contingency allowance. Use of consistent methods allows several estimators to complete various parts of the quantity survey, or be continued later by another estimator.
Cost estimating and cost planning are both an art and a science. One need not have detailed knowledge about individual tasks or techniques for this part. Progress on any activity then can be compared with the project schedule. This book also reflects the contributions of numerous students and colleagues in industry who have challenged us with problems and shared their own ideas and experience over many years. It is imperative that cost forecasts are compiled by responsible, experienced and accountable persons. A brief look at cost planning Successful cost planning is made up of diversified choices in approach and execution.
By Thomas Goubau During the implementation of a project, procedures and record keeping become and the rest of the participants in the process. These cost plans may be subject to amendment as the project passes through Project Reviews 5 and 6. A budget was then drawn up which allowed for particular materials notably a thatched roof! Make reports daily or weekly rather than at some point in time after the project is complete. In my world, with how we detail stucco, it costs just a hair more than brick. Construction costs represent only one portion of the overall life cycle costs. Furthermore, access to a personal computer with spreadsheet or equation solving software would be helpful for readers attempting some of the problems in Chapters 4 to 14. Cost estimating and cost planning outcomes provide the framework for cost control through the lifecycle of any initiative.
