Bill Of Quantities
A bill of quantities is a document used in tendering in the construction industry in which materials, parts, and labor (and their costs) are itemized. It also (ideally) details the terms and conditions of the construction or repair contract and itemizes all work to enable a contractor to price the work for which he or she is bidding. The quantities may be measured in number, area, volume, weight or time. Preparing a bill of quantities requires that the design is complete and a specification has been prepared. The bill of quantities is issued to tenderers for them to prepare a price for carrying out the construction work. 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 provides a fair and accurate system for tendering. Creation Bill of quantities are prepared by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Call For Bids
An invitation to tender (ITT, otherwise known as a call for bids or a request for tenders) is a formal, structured procedure for generating competing offers from different potential suppliers or contractors looking to obtain an award of business activity in works, supply, or service contracts, often from companies who have been previously assessed for suitability by means of a supplier questionnaire (SQ) or pre-qualification questionnaire (PQQ). The term "notice inviting tenders" (NIT) is often used in purchasing in India. An ITT differs from a request for quotation (RFQ) or a request for proposal (RFP), in which case other reasons (technology used, quality) might cause or allow choice of the second best offer. An RFP is a request for a price from a buyer but the buyer would also expect suggestions and ideas on how the project work should be done. RFPs are thus focused on more than just pricing/cost, they entail a bit of consulting from the contractor or vendor. The closest equi ...

Construction
Construction is a general term meaning the art and science to form objects, systems, or organizations,"Construction" def. 1.a. 1.b. and 1.c. ''Oxford English Dictionary'' Second Edition on CD-ROM (v. 4.0) Oxford University Press 2009 and comes from Latin ''constructio'' (from ''com-'' "together" and ''struere'' "to pile up") and Old French ''construction''. To construct is the verb: the act of building, and the noun is construction: how something is built, the nature of its structure. In its most widely used context, construction covers the processes involved in delivering buildings, infrastructure, industrial facilities and associated activities through to the end of their life. It typically starts with planning, financing, and design, and continues until the asset is built and ready for use; construction also covers repairs and maintenance work, any works to expand, extend and improve the asset, and its eventual demolition, dismantling or decommissioning.

Building Material
Building material is material used for construction. Many naturally occurring substances, such as clay, rock (geology), rocks, sand, wood, and even twigs and leaves, have been used to construct buildings. Apart from naturally occurring materials, many man-made products are in use, some more and some less synthetic. The manufacturing of building materials is an established industry in many countries and the use of these materials is typically segmented into specific specialty trades, such as carpentry, Building insulation, insulation, plumbing, and roofing material, roofing work. They provide the make-up of :Human habitats, habitats and architecture, structures including homes. The total cost of building materials In history, there are trends in building materials from being natural to becoming more man-made and Composite material, composite; biodegradable to imperishable; indigenous (local) to being transported globally; repairable to disposable; chosen for increased levels of ...

General Contractor
A general contractor, main contractor or prime contractor is responsible for the day-to-day oversight of a construction site, management of vendors and trades, and the communication of information to all involved parties throughout the course of a building project. Description A general contractor is a construction manager employed by a client, usually upon the advice of the project's architect or engineer. Responsible for the overall coordination of a project, general contractors may also act as building designer and foreman (a tradesman in charge of a crew). A general contractor must first assess the project-specific documents (referred to as a bid, proposal, or tender documents). In the case of renovations, a site visit is required to get a better understanding of the project. Depending on the project delivery method, the contractor will submit a fixed price proposal or bid, cost-plus price or an estimate. The general contractor considers the cost of home office overhead, gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quantity Surveyor
A quantity surveyor (QS) is a construction industry professional with expert knowledge on construction costs and contracts. Qualified professional quantity surveyors are known as Chartered Surveyors (Members and Fellows of RICS) in the UK and Certified Quantity Surveyors (a designation of AIQS) in Australia and other countries. In some countries such as Canada, South Africa, Kenya and Mauritius, qualified quantity surveyors are known as Professional Quantity Surveyors, a title protected by law. Quantity surveyors are responsible for managing all aspects of the contractual and financial side of construction projects. They help to ensure that the construction project is completed within its projected budget. Quantity surveyors are also hired by contractors to help with the valuation of construction work for the contractor, help with bidding and project budgeting, and the submission of bills to the client. Duties The duties of a quantity surveyor are as follows: * Cost estimate, cos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Building Estimator
A building estimator or cost estimator is an individual that quantifies the materials, labor, and equipment needed to complete a construction project. Building cost estimating can concern diverse forms of construction from residential properties to hi-rise and civil works. Both estimators and quantity surveyors must have a background education in the construction industry. Representative professional bodies which regulate property professionals: * Entry to membership of the Royal Institution of Chartered Surveyors (United Kingdom) is via four main routes: academic, graduate, technical, and senior professional and has links with a number of universities worldwide, with whom they have accredited approved courses. *The American Society of Professional Estimators - a non profit association which promotes construction estimating as a professional field of endeavor. Professional estimators use Construction Estimating Software. *The Consulting Estimator Forum is a non profit group wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bill Of Materials
A bill of materials or product structure (sometimes bill of material, BOM or associated list) is a list of the raw materials, sub-assemblies, intermediate assemblies, sub-components, parts, and the quantities of each needed to manufacture an end product. A BOM may be used for communication between manufacturing partners or confined to a single manufacturing plant. A bill of materials is often tied to a production order whose issuance may generate reservations for components in the bill of materials that are in stock and requisitions for components that are not in stock. There are two types of bill materials. A BOM can define products as they are designed (engineering bill of materials), as they are ordered (sales bill of materials), as they are built (manufacturing bill of materials), or as they are maintained (service bill of materials). The different types depend on the business need and use for which they are intended. In process industries, the BOM is also known as the formula ...

Operational Bills
Operational bills are a tendering document for estimating costs prepared by architects that describes a construction project in terms of the operations (which include labour and plant) needed to build it. This form of document contrasts with that of bills of quantities in which such tendering and estimation is limited to the materials in the completed work. Operational bills have the advantages of enhancing communication between design and production, enabling realistic tender pricing, and making the preparation of critical-path analysis easy for the contractor.Skoyles, E. R. (1966) Examples from operational bills Skoyles, E. R. (1967) Preparation of an operational bill. Building Research Station Operational bills were proposed and developed by Edward Skoyles at Building Research Establishment in the 1960s. Priced-activity schedules of the NEC Engineering and Construction Contract are a modern related form, prepared by the contractor. Potts, K. (2008). Construction Cost Mana ...

Procurement
Procurement is the method of discovering and agreeing to terms and purchasing goods, Service (economics), services, or other works from an external source, often with the use of a tendering or competitive bidding process. When a government agency buys goods or services through this practice, it is referred to as Government procurement, public procurement. Procurement as an organization, organizational process is intended to ensure that the buyer receives goods, services, or works at the best possible price when aspects such as quality, quantity, time, and location are compared. Corporations and public bodies often define processes intended to promote fair and open competition for their business while minimizing risks such as exposure to fraud and collusion. Almost all purchasing decisions include factors such as delivery and handling, marginal benefit, and fluctuations in the prices of goods. Organisations which have adopted a corporate social responsibility perspective are also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
