An estimate is a predicted expenditure of a project. It is usually taken out to get an understanding of the total budget required for a particular project. There are various types of estimates used in the construction industry. TYPES OF AN ESTIMATE Preliminary estimate The preliminary estimate is a rough estimate given to give a general idea about how much a total project will cost. It is done at the beginning of a project when only limited information is available. Such estimates are taken out to understand the total budget of a project. It helps to decide the contract price. An estimate taken out at a very early stage is called a screening estimate. It is based on information available from past projects. Example- A contractor is asked to build a backyard for a house. He had built a similar backyard a few months back to use the cost incurred in that project as an estimate for the new project. TYPES OF AN ESTIMATE Detailed estimate As the scope of the project is better known, one can take out a detailed estimate. Usually, a preliminary estimate is conver ted to an exact estimate when more information is available. Such estimates contain details of cost, quantity, rate, description of all required goods, etc. It is used as a budget estimate. It helps him to understand whether he needs additional fi nancing. A detailed estimate contains the below information: Complete information about rates used to calculate the cost Project specifi cations Drawings for all the areas included in the project Layout plans TYPES OF AN ESTIMATE Quantity estimate is an estimate which includes complete quantitative details of the material required to complete the project. It gives quantitative details of all goods required along with their cost. It is the most impor tant estimating method in construction. Cost estimates are calculated by multiplying the dimensions of the project with the per-unit cost. BID estimate A bid estimate is calculated with an expectation to win a project. It is shared with potential clients. A contractor usually tries to bid the best price to win the contract. Such an estimate is calculated based on standard industry costs or past projects. CSI MASTER FORMAT What is CSI MASTER FORMAT? CSI stands for the Construction Specifi cations Institute, a national association established in the United States in 1948. It plays a crucial role in the construction industry by providing standardized guidelines, formats, and practices, including the CSI MasterFormat. CSI MASTER FORMAT What is CSI MASTER FORMAT? The MasterFormat is especially signifi cant in the context of construction projects for organizing specifi cations and other written information for commercial and institutional building projects. It structures project information into a standardized outline, making it easier to understand, compare, and manage. CSI MasterFormat is a tool that helps professionals in the construction industry to organize and communicate CSI MASTER FORMAT What is CSI MASTER FORMAT? CSI MasterFormat is a tool that helps professionals in the construction industry to organize and communicate information about construction projects. It is a standard for organizing construction information published by the Construction Specifi cations Institute (CSI). CSI MasterFormat consists of a list of numbers and titles organized into 50 divisions, covering all aspects of construction projects. CSI MASTER FORMAT Why is it important to the Estimating Process? 1. Standardization: CSI provides a standardized framework that helps organize project information consistently across the construction industry. This standardization is crucial for estimators, as it allows for a common language and format when preparing estimates, ensuring that all par ties involved in a project are on the same page. 2. Effi ciency and Accuracy: By using a standardized system like the MasterFormat, estimators can more effi ciently organize and present cost estimates. This system helps in breaking down the project into smaller, manageable sections, making it easier to analyze costs, materials, and labor requirements accurately. CSI MASTER FORMAT Why is it important to the Estimating Process? 3. Communication: The CSI standards improve communication among all stakeholders in a construction project, including architects, engineers, contractors, and owners. A common framework ensures that specifi cations and estimates are understood clearly by everyone, reducing misunderstandings and errors. 4. Comprehensive Coverage: The MasterFormat covers all aspects of a construction project, from general requirements down to specifi c materials and processes. This comprehensive approach ensures that estimates consider every par t of the project, reducing the risk of overlooking costs. CSI MASTER FORMAT Why is it important to the Estimating Process? 5. Facilitates Comparison and Analysis: Standardized coding and categorization of project information allow for easier comparison of bids and estimates. It also facilitates the analysis of project costs over time or across diff erent projects, providing valuable insights for future estimating. 6. Adaptability: The CSI MasterFormat is regularly updated to refl ect changes in the construction industry, including new technologies, materials, and practices. This adaptability ensures that the estimating process remains relevant and up-to-date with current standards and requirements. CSI MASTER FORMAT Why is it important to the Estimating Process? 5. Facilitates Comparison and Analysis: Many estimating soft ware packages are designed to work with CSI standards, par ticularly the MasterFormat. This integration allows for the seamless transfer of information, automation of the estimating process, and enhanced collaboration through a shared understanding of project specifi cations. 6.

This adaptability ensures that the estimating process remains relevant and up-to-date with current standards and requirements. CSI MASTER FORMAT How does CSI MASTER FORMAT work? CSI MasterFormat is organized into 50 divisions. Each division represents a diff erent aspect of construction, such as concrete, masonry or electrical. Within each division, there are further subcategories that provide more specifi c information. CSI MASTER FORMAT How does CSI MASTER FORMAT work? CSI MasterFormat is organized into 50 divisions.

One challenge is that it can be diffi cult to learn and use eff ectively, especially for those who are new to the construction industry. Additionally, CSI MasterFormat is not always updated to refl ect changes in the industry, which can make it less relevant for certain types of projects. CSI MASTER FORMAT In conclusion, CSI and its MasterFormat play a foundational role in the construction estimating process by providing a structured, standardized approach to organizing project information. This standardization is key to improving the accuracy, effi ciency, and communication in the estimation and overall construction process, leading to better project outcomes. WORK BREAKDOWN STRUCTURE( WBS) What Is a Work Breakdown Structure (WBS)? is a visual, hierarchical and deliverable-oriented deconstruction of a project. It is a helpful diagram for project managers because it allows them to break down their project scope and visualize all the tasks required to complete their projects. WORK BREAKDOWN STRUCTURE( WBS) What Is a Work Breakdown Structure (WBS)? Project managers make use of project management software to lay out and execute a work breakdown structure. When used in combination with a Gantt chart that incorporates WBS levels and task hierarchies, project management software can be especially eff ective for planning, scheduling and executing projects. WORK BREAKDOWN STRUCTURE( WBS) Why Use a WBS In Project Management? Making a WBS is the fi rst step in developing a project schedule. It defi nes all the work that needs to be completed (and in what order) to achieve the project goals and objectives. By visualizing your project in this manner, you can understand your project scope, and allocate resources for all your project tasks. WORK BREAKDOWN STRUCTURE( WBS) Why Use a WBS In Project Management? A well-constructed work breakdown structure helps with important project management process groups and knowledge areas such as: Project Planning, Project Scheduling and Project Budgeting, Risk Management, Resource Management, Task Management and Team Management WORK BREAKDOWN STRUCTURE( WBS) TWO TYPES WBS: 1. Deliverable-Based Work Breakdown Structure: A deliverable-based WBS fi rst breaks down the project into all the major areas of the project scope as control accounts and then divides those into project deliverables and work packages. WORK BREAKDOWN STRUCTURE( WBS) 1.
