    Subjects Description Under the pressure of harsh environmental conditions and natural hazards, large parts of the world population are struggling to maintain their livelihoods. Population growth, increasing land utilization and shrinking natural resources have led to an increasing demand of improved efficiency of existing technologies and the development of new ones. Additionally, growing complexities of societal functionalities and interdependencies among infrastructures and urban habitats amplify consequences of malfunctions and failures. Malevolence, sustainable developments and climatic changes have more recently been added to the list of challenges. Over the last decades, substantial progress has been made in assessing and quantifying risks. However, with regard to the broader utilization of risk assessment as a means for societal strategic and operational planning, there is still a great need for further development. The book focuses not only on the more traditional technical issues, but also emphasizes the societal context of the decision making problems including the interaction between stakeholders.

If possible, same group of quantity surveyors should be arranged to take all works from inception to completion of the project. Surveying Jobs. However, in order to fully understand and appreciated the potential problems in the measurement process a thorough knowledge of measurement conventions is essential.

    The approaches to teaching quantity surveying measurement described in this paper are those adopted in the Bachelor of Construction Management BCM program in the University of Newcastle, Australia. The next step is applying a pricing list to the itemized quantities to generate a cost estimate.

    In performing construction surveying, preparation is a major part of the operation. II Areas shall be measured to the nearest 0. Traditional taking off uses dimension paper which is made of a series of columns. Use of appropriate automation tools is highly recommended. By using the same square foot area to complete the calculations for each item, allowing for the appropriate differences such as conversion to cubic yards or tons or waste factors, considerable estimating time can be saved.

    The training and knowledge of the quantity surveyor have enabled the role of the profession to evolve over time into new areas, and the services provided by the modern quantity surveyor now cover all aspects of procurement, contractual and project cost management. By surveying, the site elevations of the existing earth at various points of the work site are determined. Bills of Quantities are necessary for effective control of construction production and associated costs.

    The following paragraphs present the detailed quantity estimate of materials such as concrete, formworks,. It must be as accurate as possible and should be based on all available engineering and design data. Since the beginning the roles and duties of a Quantity Surveyor have changed a lot. Send us your drawings cad or pdf format , specification and bills of quantity if any, we are able to to revert with the full set of quantity measurement as per your requirement.

    Seeley, 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.

    This quantity takeoff sheet also includes ductwork, piping , labor , risk cost and summation of all the estimated expenditure. Quantity takeoff or calculating sheet is the common type of indexing and taking off dimensions, amounts of substance needed and sorts needed in a bidding method of a construction task.

    PDF Available BIM automation in the quantities take-off would reduce changes and reworks that effectively improves the take-off item including the item description, quantity, unit of measure, unit price, and extended or total price. An essential guide to any quantity surveyor, architrect or engineer 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.

    All works shall be measured subject to the following tolerances. This book provides a thorough understanding of the general principles of measurement for taking off quantities.

    Accuracy and completeness are critical factors in all cost estimates. Trick of the Trade 1: To find the length of Excavation — Be careful to fully understand what the given dimension are measuring. We are not objecting the normal way of taking-off the quantity and estimation, as pdf software or manually takeoff can also perform a good job equally fairly.

    Now a day Quantity surveyors in industry, they have varies qualifications. Dimensions shall as far as possible be given in the following sequence: 4. Here is how it works. The Quantity Surveyor should then complete the draft Cost Plan based on these assumptions for circulation to the Employer and the Design Team for review.

    These publications do not explain the taking-off process. An estimator could type all of the necessary information in each cell. For various civil engineering projects like road work, irrigation canal project, tank survey, earth moving, etc.

    The process of outputting a quantity take-off is cyclical to match the design submittal requirements. QSPlus International effortlessly prepares cost plan estimates to all levels of detail, so you can present the elemental cost plan in various formats.
