Scientists are always asking questions that can only be satisfactorily answered by making calculations or applying formulae to produce a meaningful number or set of results. Multiplying a vector by any negative value other than minus one will both reverse the direction and change the magnitude of the vector. bill of quantities 工程量清单 ; 工程量表 ; 建筑工料清单 ; 工料清单. PREAMBLE TO BILL OF QUANTITIES (BOQ) 1. The first is that, unlike pure numbers, scalar quantities can refer to different types of physical quantity. Each line of text contains fixed length fields as follows. And that's just for … In this case, the Bill item includes a component or accessory that is part of the fixture, but the Estimator did not mention that it has been measured elsewhere. We can add any number of vectors together, as demonstrated by the vector diagram below. Vector v is the hypotenuse of a right-angled triangle. This is a far more concise (and often less error-prone) way of adding vectors. PLAY VIDEO Find out how QSPlus gives you the competitive edge with Valuations. Physicists, for example, are interested in the forces acting upon an object that is at rest or in motion. For those in the construction business, bill of quantities can be used by you to give a bill of your services to your customers. 00:00 / 00:00. Quantity Take-off: Direct Entry Measuring, CAD Measure. In some cases, the force required to achieve a task must be applied indirectly. Mar 23, 2018 - Bill of quantities - Free download as Word Doc (.doc), PDF File (.pdf), Text File (.txt) or read online for free. Snape Vector is surveying software program for professional quantity surveyors and building estimating professionals to create detailed Estimates from Specifications and Drawings in any order and presentation ranging from builders Quants, SMM7, Element, Phase, Trade Package etc. Every working day hundreds of surveyors are using Vector to create bills of quantities, cost plans and detailed building estimates for their clients of every conceivable kind. The calculations made by scientists naturally involve quantities of various kinds. You can arrange the vectors in any order and get the same result. Quantities that have a directional component are called vector quantities. It is of course possible to multiply the x and y components of a vector by two different scalar values, which produces a vector that points in a different direction. Adding a quantity of length or time to a quantity of mass, on the other hand, would produce a result that is totally meaningless. Examples of scalar quantities include length, mass, time, and amount of substance. The vectors are simply placed so that the head of the first vector points to the tail of the next vector, and so on. Access ConQuest Estimating software is packed with time-saving features that help you remove admin from your workload: Create and send hundreds of subcontractor enquiries in less than an hour. Bills of Quantities that are required for a lump sum contract based on firm or approximate quantities will normally be prepared by the employer’s quantity surveyor, whereas under a design and build contract, the employer’s project team will prepare the employer’s requirements and the Bill of Quantities or quantified schedules of work will be prepared by either the main contractor or, more likely, the main contractor’s work package contractors. The vector arithmetic involved in this kind of calculation is somewhat beyond what we have discussed here. To produce a full Bill Of Quantities report for your job in Cubit Estimating, you would just need to do the following: 1. All of these statistics are, of course, scalar quantities. Our many users have told us that QSPro is the easiest to use bills of quantities and construction cost estimation software offering best value for money. Recall is the process accomplished by the end user when a vector of attribute values . This will generate a BOQ report based on the current job information and display this on-screen. Fig.1 Generate Button. Click the Generate button in the BOQ section. The moon is approximately 4.527 billion years old(image credit: Nasa/Bill Ingalls). It provides estimating and takeoff features. In a two-dimensional environment, for example, a vector will have an x component and a y component, as shown in the diagram below. We use Vector Quantity Surveying & Estimating software which provides a fully integrated approach to the preparation and use of documentation for the procurement and control of construction projects and also allows us to produce Bills of Quantities and detailed Estimates for main … Dublin +353 (0)1 554 7311, Our bills of quantities can be prepared using, (SMM7), New Rules of Measurement (NRM 2) and Agreed Rules of Measurement 4, Detailed and accurate Bills of Quantities produced, Standard Method of Measurement (SMM7) or New Rules of Measurement (NRM 2) and Agreed Rules of Measurement 4, Based on Civil Engineering Standard Method of Measurement 3, Bespoke Measurement in accordance with contractors requirements, Bills of Quantities can be converted and presented in Excel or CITE formats for importing into your estimating software, or delivered electronically, CD, or hard copy, Firm (to obtain a lump-sum price for a fully designed building project), Approximate (subject to re measurement as built), Form of Tender (including certificate of bona fide tender). Final invoices, bills of quantities, design documents, and bridge drawings were . From the above diagram, we can see that vectors can be represented graphically using arrows. The components of a vector are usually (though not always) perpendicular (at right-angles) to one another. The practice uses Vector Quantity Surveying & Estimating Software which is highly regarded as excellent software in the construction industry, and is used by many Quantity Surveyors & Estimators worldwide. You can only use operations like addition, subtraction, multiplication and division on scalar quantities of the same type. PlanSwift. size) but not direction. These quantities fall into two basic types - scalar quantities and vector quantities. Proposed landscape design at.. If y… can be locked by Vector Excel Spreadsheet with Lines and Formula Vector Presentation View Vector export to Excel is particularly cap-able. 101 activity or locational bills • activity or locational bills refer to operational bills of quantities measured in accordance with the smm for building works but in which the … Credits (for materials arising from the works). The bill of quantities enables tenders to be prepared efficiently and can be used to value work completed once the contract has been let. A special case of this is where we multiply a vector by minus one (-1). The length of a piece of string might be expressed in inches or centimeters. One important thing that makes a Bill useful to the contractor, owner and other members of the project team is how the Bill items are described. BOQ Summary Report: Vector produces a complete working Bill of Quantities in Microsoft Excel format that mirrors the printed bill in appearance and is complete with carried forward headings, formulas, lines, collections and summaries. Let's look at a couple of examples. contract bill of quantities-BOQ 合同数量单 ; 合同数目单 ; 合约数目单 ; 条约数量单. 2.9: Products of Vectors (Part 2) Another kind of vector multiplication is the vector product, also known as the cross product, which results in a vector perpendicular to both of the factors. The estimator will measure the drop-in vanity basin under Plumbing and Drainage, but does not mention that the vanity top/cabinet has been measured elsewhere (under Carpentry and Joinery). Character Position Field Description; 0: Information Identifier: 2-11: Reference: 13-62: Text: 64-74: Quantity: 76-79: Unit of Measure: It can be realized as a measurement, whose results indicate directly a value of measured electric quantities, such as voltage, current, resistance, etc., or a measurement, where measurement of electrical quantities is only an internal function of This is the kind of calculation we would typically make to find the area of some surface (the surface area of a solar panel, for example), so an answer expressed in square metres would make sense. Week 12 Civil Engineering The diagrams within cesmm4 examples include some helpful shortcuts for engineers and surveyors preparing bills of quantities and this edition has been published in a larger format to enable the diagrams to be more easily interpreted. and Building Estimating Professionals. to understand the Bill of Quantity (BOQ) … or "How far is it from here to the Moon?" Vector v has component vectors x and y. a quantified schedule of rates), since the quantities are subject to re-measurement on completion by the quantity surveyor. Bill of Quantity (BOQ) Definition: It is a document used in bidding. This makes sense when you think about it, since the shortest distance between two points is always a straight line. The Bills of Quantities which we provide our clients with can include the following main sections: We are able to provide our clients including private clients, contractors and sub-contractors with bills of quantities for their project to assist with tendering, Our bills of quantities can be prepared using (SMM7), New Rules of Measurement (NRM 2) and Agreed Rules of Measurement 4, We prepare builders quantities for contractors and sub-contractors tendering on projects. Egypt. The program is a thoroughly modern bill of quantities program with drag and drop, unlimited undo and redo of every action you take and all the other features you would expect in the best modern windows programs. length) of the vector unchanged, and simply reverses its direction. This time, the x and y component vectors have been arranged so that they form the legs of a right-angled triangle, for which vector v forms the hypotenuse. Make revisions to quotes in seconds. We can find the magnitude of vector v (i.e. SC Quantity Surveyors can provide a professional Bills of Quantities solution thereby saving contractors and sub-contractors the high costs involved in employing a full time department to carry out this work. Bill of Quantities. A far more detailed treatment of vectors can be found in the Mathematics section of this website, in the section entitled "Vectors and Vector Arithmetic". Force is a vector quantity because it has both magnitude and direction. Financial Statements. Although the measured quantities are approximate, the descriptions of work items should be correct in the approximate bill of quantities. The direction of the new vector will be exactly the same as that of the original vector. Insurance claim reports. Quantities such as displacement, velocity and force have direction as well as magnitude, so they are all vector quantities. They can be added or multiplied together, and one scalar value can be divided by or subtracted from another scalar value. Every working day hundreds of surveyors are using Vector to create bills of quantities, cost plans and detailed building estimates for their clients of every conceivable kind. We often need to apply a force to an object in order to achieve some task. One interesting thing to note here is that, unless all of the vectors being added together are pointing in exactly the same direction, the magnitude of the resultant will always be less than the combined magnitude of the component vectors. Preliminaries, comprising two main section as follows: Measured works (incorporating the contractor designed works eg. Bill of material template can be used by dealers of various raw materials which the buyer combines to manufacture an end product. Bill of Quantity or Bill of Material is the breakdown of items of material to be procured and work to be accomplished for completion of a project or manufacture of a product. While we're on the subject, the Moon's mass is estimated at 7.34767309 × 1022 kilograms, and it has an estimated age of 4.527 billion years. We can represent vector subtraction graphically, as shown below. We therefore need to be able to resolve forces into their component vectors in order to work out how much force must be applied in a given direction in order to achieve a particular task. The head of the arrow points in the direction of the vector, while the length of the arrow represents the vector's magnitude. We can add vectors together without having to draw a vector diagram simply by summing their x and y components to find the x and y components of the resultant. You will come across vectors frequently when studying the physical sciences. BOQ descriptions should be specific with relevant information that helps …. in large quantities 大量 ; 大批 ; 多数的 ; 年夜量. We simply add vectors a, -b and c together instead of subtracting vector b from the sum of vectors a and c. Here is the result of adding vectors a, -b and c. Multiplying a vector by a scalar value is a relatively straightforward operation, and produces another vector. Project Management services. The same algebraic operations can be carried out on scalar quantities as on pure numbers. Here once more is the first vector we looked at. The vector we obtain by adding two vectors together in this way is called the resultant. Preparing Bills of Quantities (BOQs) is one of the tasks of a Quantity Surveyor or Construction Cost Estimator. This type of vector multiplication is used to find angles between vectors and in the definitions of derived scalar physical quantities such as work or energy. They have magnitude, but not direction. Bills of Quantities which we provide contractors with includes the following benefits:-, The main use of a bill of quantities in support of a contract is the traditional and proven means of securing a lump-sum price for carrying out the building works for the client.SC Quantity Surveyors produce several types of Bills of Quantities which include. Drawing up of Specifications and Bill of Quantities. Most of the vector quantities you will come across in the study of physics will have either two components (vectors that indicate a magnitude and direction in a two-dimensional plane) or three components (vectors that indicate a magnitude and direction in a three-dimensional space). Here is the calculation: v = √(x 2 + y 2) = √(16 + 9) = 25 = 5. Each of the base quantities has a single dimension. When multiplying two scalar quantities together, however, we must multiply the units together as well. Which include details the terms and conditions of the construction contract and itemizes all work to enable a contractor to price the work for which he is bidding. entered in the Bill of Quantities shall be deemed to be the full inclusive value of the work covered by the several items including the following, unless expressly stated otherwise: (i) Labour and costs in connection therewith. The distance from the Earth to the Moon would be expressed in kilometres or miles (the average distance is in fact 384 403 kilometres or 238 857 miles). large quantities of 大量的 ; 大批的 ; 大量滴 ; 大量哒. Two-dimensional vectors lie in the same plane, and are therefore said to be co-planar. Examples might include such diverse activities as lifting a block of concrete into position, towing a trailer or caravan, or placing a communications satellite into orbit. For you to be called a good Quantity Surveyor, a good takeoff should be produced so that the client will know the prices of the identified elements, which is necessary in producing the Bill of Quantities. Rehabilitation/forensic works investigation and reporting. The physical sciences are by their very nature highly mathematical. QSPro has been designed by software professionals but with the guidance of John Austen FRICS of John Austen Associates who have been using our software since it was originally developed in 1994. This leaves the magnitude (i.e. You can create a customizable report to build cost plans and bill of quantities for the clients’ needs. Should you have any queries please contact us below. Pull up detailed project reports and audit trails instantly. Quantities that have a directional component are called vector quantities. These types of contracts do not provide a lump-sum price, but instead tender price totals (ie. In some cases, the resultant may be the zero vector, if both the x components and the y components of the vectors being added together sum to zero. It is important to note that the initial resource cost of approximate bills of quantities is likely to be lower than firm bills of quantities, but the need for re-measurement invariably results in an overall higher resource cost. The answer is relatively straightforward. We can also multiply a vector by a negative number, in which case the resulting vector will point in the opposite direction. Detailed Building Estimates with full Resource Analysis. When vectors a, b and c are added together, the resultant is vector v. Vector v in this example is the resultant of adding vectors a, b and c. Note that it has x and y components of five (5) and one (1) respectively. In a two-dimensional plane, a vector has an x component and a y component. pre-cast concrete floors/stairs, windows etc). Here, we subtract vector b from the sum of vectors a and c. We effectively achieve this by reversing the direction of vector b, which as a result is now shown on the diagram as vector -b. (ii) The supply of materials, goods, storage and costs in connection therewith including delivery to Site. Find out how QSPlus gives you the competitive edge with superior accuracy and speed. An example is a Vitreous china drop-in vanity basin that includes a vanity top or cabinet. With that being said, as a Quantity Surveyor, you are responsible for the Bill of Quantities that a construction company should follow. This means that vector v is the result of adding vectors x and y together. You can add ten kilograms (10 kg) to five hundred grams (500 g) for example, but you must express both amounts in the same units (either grams or kilos). The software also contains a CAD measurement module that will be helpful for land survey. You might also have realised that the x and y components of a vector are themselves vectors, although essentially one-dimensional vectors. Bills of quantities are supposed to describe and accurately present the quantity and quality of the works to be carried out. Nowadays, the measurement of electrical quantities is an essential part of almost any measurement. For example, if we had five (5) identical gold bars, each with a mass of six kilograms (6 kg), we could multiply six kilograms by five to obtain a total mass of thirty kilograms (6 kg × 5 = 30 kg). Think about questions such as "How long is a piece of string?" We use Vector Quantity Surveying & Estimating software which provides a fully integrated approach to the preparation and use of documentation for the procurement and control of construction projects and also allows us to produce Bills of Quantities and detailed Estimates for main … The magnitude of a vector is indicated in the diagram by its length. In general these contracts are usually subject to greater variation than lump sum contracts and therefore should only be used where time is a limiting factor or where there is great uncertainty in respect of certain elements, such as major excavations and earthworks. The normal rules of arithmetic do of course apply to algebraic operations involving scalar quantities. Simply multiply both the x and the y components of the original vector by the scalar value to get the x and y components of the new vector. SC Quantity Surveyors can produce approximate bills of quantities which are mainly used when there is insufficient details to prepare firm bills of quantities or where the client has decided that the time and cost of a firm bill of quantities is not warranted. the length of the vector) using Pythagoras' theorem. We can talk about length, for example, without having to think about a particular direction. The CITE Bills of Quantities produced by BQ Filter are plain text files which can be viewed using Notepad or WordPad and have the file extension .ebq. Most of the vector quantities you will come across in the study of physics will have either two components (vectors that indicate a magnitude and direction in a two-dimensional plane) or three … SC Quantity Surveyors - Chartered Quantity Surveyors, London (+44) 020 3322 6069 Subtracting one vector from another is also relatively straightforward. Multiplying or dividing a scalar quantity by a pure number is perfectly legitimate. We are available to contact during the office hours and times below. We use Vector Quantity Surveying & Estimating software which provides a fully integrated approach to the preparation and use of documentation for the procurement and control of construction projects and also allows us to produce Bills of Quantities and detailed Estimates for main contractors and sub-contractors. We will deal with scalar quantities first, since they are relatively straightforward. We have already mentioned the magnitude of vectors several times, but how do we actually find the magnitude of a vector if we only have its x and y components? Cost Plans, Approximate Estimates. PlanSwift is the best quantity takeoff software. Vector is a thoroughly modern Bill of Quantities program with drag-and-drop, unlimited undo & redo of every action you take and all the … Specifications, Preambles, Preliminaries. Note that when subtracting a vector algebraically, the easiest method is simply to negate the values of the x and y components of the vector to be subtracted, and then just find the sums of the x and y components, as we would do for any other vector addition. If we multiple three metres (3 m) by five metres (5 m), for example, we get the result fifteen square metres (15 m2). There are however one or two things to be aware of. Working in Vector company as an electrical procurement and technical office : Responsibilities: Develop electrical shop drawing at different project stages. In general the choice of who quantifies building works is solely down to the employer’s preference of contract strategy. You may have already realised that each of these examples is one of the base quantities defined in the International System of Units. These questions have answers that can be expressed as a single number, followed by the appropriate unit symbol. [Filename: boqtankl1.pdf] - Read File Online - Report Abuse. GENERAL The nature of this contract is measured unit price contract and the Bill of Quantities (BOQ) shall reflect this fact. Typical services offered include: Civil and Structural Engineering Design within the commercial, residential, industrial and telecommunications sectors respectively. • the advantages and disadvantages of sectionalised trade bills are the same as that for elemental boqs. For many of these firms and individuals they quite literally earn their living using Vector. A scalar quantity is a quantity of something that has magnitude (i.e.
