taking off quantities from drawings examples

After an estimator has compiled a comprehensive list of the materials required, their specifications, and their quantities, the estimator can then begin to prepare a material price estimate. The process for creating a quantity takeoff demands a high attention to detail and thoroughness. For prefabricated items such as light fixtures, a simple count will usually suffice. A manual quantity takeoff is simply a takeoff that is completed without the assistance of digital takeoff software. This happens frequently during projects. Along with the required amount of each material, the estimator will compile a comprehensive list of costs for the associated materials. If the software has the capability, price information can be drawn from a database of current prices populated by the contractor. 4 Steps to Align Your Construction Team for Peak Performance, 2020: Navigating a Year of Unprecedented Change, Discover What Your Pre-construction Takeoff Process Is Missing, 5 Construction Risk Solutions for Your Estimation Team. Although quantity takeoffs are themselves complex, they have a simple purpose. General contractors, subcontractors, quantity surveyors, and estimators routinely produce quantity takeoffs during the estimation process. Quantity takeoffs are prepared by a wide range of people and organizations within the construction industry, and each quantity takeoff can be unique. Each individual or organization may find a method of preparation for their quantity takeoffs that they prefer and may format their final quantity takeoff cost analysis in different ways. Many people still complete quantity takeoffs manually, but do so with the assistance of computer software that information is entered into by hand. As you could assume, there are many, benefits of using construction estimating software. Second, digital takeoffs take much less time to produce. Although quantity takeoffs are themselves complex, they have a simple purpose. Add 15 to 20 percent to the cost of materials to account for waste. Substructure work is typically the first class of work to be explained in textbooks dealing with both construction technology and Quantity takeoffs fulfill two basic functions in a construction cost estimate. process. Quantity takeoffs are an important aspect of the construction cost estimating process. Digital quantity takeoffs are completed using a construction cost estimation program that contains digital takeoff capability. Taking another example, a quantity takeoff would detail all of the steel piping required for a project and would include details about the length and width of piping, and ensure that the piping that will be ordered will meet design specifications. For materials like lumber, the quantity takeoff would include what specific type of lumber the job requires, the length and width of the lumber, and may include the total weight of the required lumber for shipping considerations. Any complex calculations required for assigning quantities to materials are embedded into the program, making this process vastly easier than a manual quantity takeoff. This will include all raw materials, like lumber, concrete, asphalt, and steel. Long wall (out-to-out) = c/c length + 1/2 breadth on one side + 1/2 breadth on the other side. Once prices are applied to each material, the estimator can dynamically adjust the price to account for material cost increases. to run your calculations. The bill of quantities assists tenderers in the calculation of construction costs for their tender, and, as it means all tendering contractors will be pricing the same quantities (rather than taking off quantities from the drawings and specifications themselves), it also Let’s examine these two different types, and highlight the positives and negatives of each approach. This process - known as booking dimensions or taking-off quantities - involves the measurer in either reading or scaling 10) = c/c length + one breadth. General contractors, subcontractors, quantity surveyors, and estimators routinely produce quantity takeoffs during the estimation process. They also do so by integrating the calculating function into the program itself, which eliminates the need to perform complex calculations. Determining the price of materials can be accomplished in a number of ways. There is a high level of detail required when quantifying material in a construction takeoff. For more information on construction estimating software pricing and subscriptions, please call our customer service today. 10) for students to commence the process of taking-off building quantities. Only by taking the information “off” documents can estimators convert information from drawings into a list of items with quantities that can be measured. Clients will often accept bids from multiple contractors for the same project. Determining what factors may impact the total material costs, and therefore applying an appropriate markup to account for cost fluctuations is one of the most difficult jobs of a cost estimator. If one contractor’s material costs are significantly different from another contractor it may raise some suspicions. %PDF-1.4 You should expect More than that, with the integration of 2D and 3D design data, Autodesk Quantity Takeoff brings drawings and data together in a way that has never before been possible. As part of this process, the estimator or contractor will need to note specifics about each material. This book is very important to students studying Civil engineering and Quantity surveying in higher institutions. The first part of a quantity takeoff involves putting together a list of all of the materials required for a project. This last point is because a quantity takeoff will also need to include a certain amount of extra material to account for wastage during the construction process. We specialize in providing take-off/estimating services for construction and engineering firms at various stages throughout the construction process. 335 0 obj Home » What is a Quantity Takeoff in Construction? While some in the construction industry may not routinely work on quantity takeoffs, they may still wonder, what is a quantity takeoff in construction, ? First, digital takeoffs help reduce errors associated with quantity takeoffs. Second, they provide a total material cost for a project, which is then incorporated into a detailed cost estimate. 336 0 obj Here is the short cut for you. 1.1.1 Lump Sum Contracts with Drawings and Specification 9.10 1.1.2 Lump Sum Contracts with Firm Bills of Quantities 9.10 1.1.3 Remeasurement Contracts with Approximate Bills of 9.10 Quantities 1.1.4 Schedule of Rates Contracts 9.10 1.1.5 Design Alternatively, some takeoff software can draw cost data from online construction cost databases such as RS Means. Taking Off Foundation - Free download as PDF File (.pdf), Text File (.txt) or view presentation slides online. For example, subcontractors may routinely prepare quantity takeoffs that include the same materials. Taking off quantities: Civil Engineering demonstrates, through a series of detailed worked examples from a range of civil engineering projects, how the measurement techniques are actually used. They may increase requirements for certain materials where wastage is common during the construction process. stream 2011-10-29T20:19:22Z This provides a better understanding of what is required for a quantity takeoff, as well as how one is constructed. Lastly, digital quantity takeoffs require less specialization to complete than a manual takeoff. = c/c length – one breadth. Although each program has its own suite of features, the basic process of creating a digital quantity takeoff is roughly the same. If done by hand, the estimator must make complex calculations. For other projects, estimators may use a personal database of material costs, or draw information from a third-party construction costs database like RS Means. This is necessary to produce bills of quantities and requires that the design is complete and a specificationhas been prepared. Taking off Quantities: Taking off is the process of analysing the drawing and its specifications to identify the elements required for the preparation of BOQ. Create a spreadsheet for your bill of quantities with columns for the item numbers, descriptions, units of measurement, quantities, rates for each item, labor, and total cost. During the estimation process, an estimator may have to make frequent adjustments to there quantity takeoff. Any complex calculations required for assigning quantities to materials are embedded into the program, making this process vastly easier than a manual quantity takeoff. In order to determine a total cost estimate, the contractor or estimator will need to determine the cost for each specific required material. First, they detail what materials need to be purchased to complete a project. Quantity takeoffs are generally performed early on during the bidding process. You may also hear a quantity takeoff referred to as a construction takeoff. Traditional Take Offs The availability of digital drawings at Tender Stage is not always an option and therfore the traditional methods for taking off quantities and lengths is necessary. Once you have known about the types of taking offs, then here are some of the methods to master construction take off. From there, the estimator can apply prices to each material. The bill of quantities assists tenderers in the calculation of construction costs for their tender, and, as it means all tendering contractors will be pricing the same quantities (rather than taking-off quantities from the drawings and specifications themselves), it also Material costs can rise over time. When preparing the bills of quantities, a series of steps must be carried out in proper order so as to make the bill of quantities managed and easy to understand. Quantity takeoffs are used to provide a list of all of the materials required for a construction project. You may also hear a quantity takeoff referred to as a. . An estimator would examine physical drawings or blueprints and painstakingly create a list of materials. In order to produce a quantity takeoff, the estimator or contractor will need to work off of drawings, blueprints, or models. A markup for material costs is necessary for most projects to ensure a project remains profitable for the contractor. Use of The software addresses key requirements for cost estimators by giving users more flexibility The oldest form of quantity takeoffs is completed manually. For materials like lumber, the quantity takeoff would include what specific type of lumber the job requires, the length and width of the lumber, and may include the total weight of the required lumber for shipping considerations. Quantity takeoffs are used in both large and small projects to determine actual costs, ensure that a project remains profitable to the contractor, and are a vital component of a final detailed estimate. They do so by drawing information directly from the blueprint, which adds a layer of redundancy to ensure that the estimator hasn’t missed any materials. , please call our customer service today. 1. While these skills are still necessary, the barrier to producing an accurate quantity takeoff has been reduced in some ways through the use of digital estimation software with an integrated ability to produce digital takeoffs. At this point, the estimator can make any adjustments to the material requirements that they see. Quantity takeoffs are an important aspect of the, process. 2. Quantity takeoffs also provide costs for each material. #1. How much or little of a markup occurs will depend on a number of factors, and can be a key determinant of whether a bid is accepted or rejected. Nitro PDF Professional (6. There is a high level of detail required when quantifying material in a construction takeoff. Given that material costs represent a sizeable portion of total construction costs, the quantity takeoff must be accurate and up-to-date. Despite the unique nature of each quantity takeoff and the various ways they are approached, there are two broad types of quantity takeoffs. Quantity takeoffs are used in both large and small projects to determine actual costs, ensure that a project remains profitable to the contractor, and are a vital component of a final detailed estimate. At this point, the estimator can make any adjustments to the material requirements that they see. Providing the correct quantity for the material is essential, so estimators will need to be familiar with construction conditions, the materials that are used, and a good understanding of the construction process. The term “takeoff” refers to this process of “taking off” all of the materials for a project from a design drawing or blueprint. The term “takeoff” refers to this process of “taking off” all of the materials for a project from a design drawing or blueprint. This will include all raw materials, like lumber, concrete, asphalt, and steel. Digital quantity takeoffs are completed using a construction cost estimation program that contains digital takeoff capability. Once prices are applied to each material, the estimator can dynamically adjust the price to account for material cost increases. Taking off Quantities: Civil Engineering: sets taking off in the wider context of measurement; is presented in large format, with clearly laid out drawings; includes explanatory notes to support the taking off examples; is more than a dull, mechanistic book on A quantity takeoff is created to provide a list of all of the materials necessary to complete a project. 22 TAKING OFF QUANTITIES: nature and extent of the work’ (or as near as it is possible to define it) must be determined from the Drawings, the Specification and the Contract. Cost Estimating 21 Dr. Emad Elbeltagi CHAPTER 2 QUANTITY TAKE-OFF The quantity “takeoff” is an important part of the cost estimate. The item descriptions should not be held to be comprehensive but used to ‘identify’ the work being measured. While some in the construction industry may not routinely work on quantity takeoffs, they may still wonder what is a quantity takeoff in construction? In the preparation of the bill of quantities, the first step includes taking off the quantities from the working drawings. Because of this, the quantity takeoff is often a living document that undergoes many changes until a design is decided upon and a bid is secured. What is a Quantity Takeoff in Construction? This article will seek to answer this question by defining what a quantity takeoff is, what the components of it are, and how it fits into the construction estimation software process. For larger projects, determining the itemized material costs and arriving at a total material cost can be very time-consuming. Taking another example, a quantity takeoff would detail all of the steel piping required for a project and would include details about the length and width of piping, and ensure that the piping that will be ordered will meet design specifications. 2011-10-29T20:19:58Z If the estimator is producing a quantity takeoff manually, they will need to be comfortable performing complex calculations. 3- Volume of mortar = (.01166 ft /brick) x (982 bricks) = 11.4 ft3. A quantity surveyor may take off quantities from detail drawings to produce a bill of quantities for tendering purposes. If the software has the capability, price information can be drawn from a database of current prices populated by the contractor. Although still aided by a computer, the process is still largely manual. As part of this process, the estimator or contractor will need to note specifics about each material. In the past, manual takeoffs were done completely by hand. Quantity takeoffs don’t just save time when creating a takeoff, but they also save time when a quantity takeoff has to be adjusted. A quantity for each material will be provided, hence why they are called a quantity takeoff. They may increase requirements for certain materials where wastage is common during the construction process. As you could assume, there are many benefits of using construction estimating software to run your calculations. That being said, digital takeoff software facilitates the production of quantity takeoffs by automating many of the more tedious aspects, while also ensuring that takeoffs are accurate and produced in as little time as possible. This process will vary depending on who is preparing the cost estimate. Along with the required amount of each material, the estimator will compile a comprehensive list of costs for the associated materials. construction estimating software pricing and subscriptions. From there, the program analyzes the blueprint or drawings and generates a list of all of the required materials. To be sure, a quantity takeoff is still complex. In addition to raw materials, the quantity takeoff will include any prefabrication in construction that are necessary for the project. For manual takeoffs, the estimator must be extremely knowledgeable about the project, the construction process must understand how to read and interpret blueprints and drawings, and must be able to perform complex calculations. Taking off Quantities: Civil Engineering: sets taking off in the wider context of measurement; is presented in large format, with clearly laid out drawings; includes explanatory notes to support the taking off examples; is more than a dull, mechanistic book on The information from a quantity takeoff is incorporated into a final detailed estimate, along with things like labor costs, office overhead costs, subcontractor costs, and equipment rentals. © Copyright 1976 - 2020 - ProEst - All Rights Reserved. <> <. For prefabricated items such as light fixtures, a simple count will usually suffice. A more thorough process is necessary for major construction projects, however. First option is explained in previous answers which is a little boring job to use spreadsheet software to estimate quantities and costs of buildings from drawings. Up until relatively recently, preparing a quantity takeoff required a high degree of skill, as well as good judgment and critical thinking skills. endstream From there, the program analyzes the blueprint or drawings and generates a list of all of the required materials. While this may not be the case for smaller projects, large or complex projects will almost certainly require many revisions to the quantity takeoff. Digital takeoffs improve over manual quantity takeoffs in a number of ways. This is especially true for large projects or projects where prices for critical materials like lumber or steel rise quickly over a short period of time. First, a blueprint is uploaded or scanned into the program. Not accounting for the increase in material costs will impact the profitability of the project. Step 1: Calculate out the volume of mortar of one brick. We’ll also look at the different ways quantity takeoffs are completed, and what the advantages and drawbacks of these different methods are. (ft3or m ) - Volume per brick = (t)(w)(L+H+t) 3- Volume per brick = (.5)(3.75)(8.0+2.25+.5) = .01166 ft Step 2: Multiply the mortar required/ brick by the total number of bricks. The building that will be used to calculate the quantities and cost estimation is shown at the figure on the right. Quantity takeoffs are an integral part of the cost estimation process. that are necessary for the project. Book Description This book provides a thorough understanding of the general principles of measurement for taking off quantities. %���� For large projects, the estimator would seek a bid from a material supplier. The term ‘taking off’ refers to the process of identifying elements of construction works that can be measured and priced. This reduces labor costs associated with producing a quantity takeoff, while also allowing the contractor to seek other opportunities and bid more projects with the time they save. If done with a computer, software such as Excel can be used to perform certain calculations. 2.2.1 Taking –off quantities In the first instance quantities need to be extracted from drawings, together with an appropriate description. An essential guide to any quantity surveyor, architect or engineer. 2. From the design paperwork, the estimator will prepare a list of each material needed to complete a construction project. endobj Most often, the person preparing the quantity takeoff will markup the total material costs. From there, the estimator can apply prices to each material. 1. We’ll also look at the different ways quantity takeoffs are completed, and what the advantages and drawbacks of these different methods are. While manual quantity takeoffs are still widely in use, they are slowly falling out of favor due to the clear advantages that digital quantity takeoffs provide. Materials like concrete and asphalt will need to be quantified in volume, whereas materials like flooring or tile will need to be calculated using area or square feet. The first part of a quantity takeoff involves putting together a list of all of the materials required for a project. Today, the majority of bills of quantities are produced using proprietary software packages, each system having its own format for inputting dimensions and formulating descriptions. In addition to raw materials, the quantity takeoff will include any. If the cost of those materials is known and stable, the subcontractor can simply plug in their known prices into their quantity takeoff. 2011-10-29T20:19:58Z A quantity takeoff is created to provide a list of all of the materials necessary to complete a project. It includes a variety of trades such as clearing site, top soil removing, excavation, concrete work and Once prices for each material have been determined, the estimator will then produce a total material cost estimate. For a small one-off job, an experienced builder should be able to estimate the materials required in his or her head. These are the basic elements of a construction quantity takeoff, but it is worthwhile to dive deeper into the other components of this type of takeoff. It must be as accurate as possible and should be based on all available engineering and design data. Additional info: First, a blueprint is uploaded or scanned into the program. Nitro PDF Professional (6. On smaller projects an estimator may need to measure the quantities from the tender drawings and specifications as part of a tender submission. Short wall length in-to-in = c/c length – 1/2 breadth on one side – 1/2 breadth on the other side. Recently, digital takeoff software has become increasingly popular for preparing takeoffs. This may be due to design changes, additional engineering requirements, or changes in what the client wants. This allows people that aren’t professional estimators to produce accurate and comprehensive construction quantity takeoffs in very little time. Alternatively, some takeoff software can draw cost data from online construction cost databases such as RS Means. Breaking down the Process You need to master how you will break down every process to suit your workflow. With digital takeoff software, many of these functions are integrated into the software itself. Detail taking off examples such as Roads, Reinforcement, Retaining walls, etc. It is important to approach the task in a methodical manner in order to achieve the most accurate approximation possible.
