The price could potentially be reduced significantly if the industry were to embrace the concept of quality assurance that has been used with great success by many other sectors of the economy.

The development industry is exclusive, and so, the applying of quality assurance requires an approach that meets the requirements of the industry. Building owners also got to be educated on what's quality assurance in order that they'll begin using their voice to encourage adaptation of this approach to guard their investments and reduce the price of construction.

The quality assurance and internal control has broad meaning as per as various sectors are concerned. Normally to grasp this idea of quality, we formulate four questions as follows, 1. What's mean by Quality? How it's achieved? What's Quality Assurance? What's Quality Control? When we are talking about quality about anything, either its service or any product; one word should are available mind as response i.

There shouldn't be any response to differentiate quality viz; fair quality, moderate quality, quite poor or quite good quality. Ultimately the presence of quality is very important.

So normally we are able to define the standard in several ways as follows, -Quality is conformance to requirements or specifications. A key to this is the increased sophistication of clients in applying the requirements of the standard forms of building contract. These contracts clearly place the burden of proof on the contractor. The task of providing this proof, often in the form of documentary evidence, is frequently complicated by a lack of pertinent records.

Therefore to make things worse economic loss is often accompanied by loss of good will Examination of project records shows that questions have not been asked when they should have been, problems are not seen until after they have occurred.

It is typically not the case that the individuals involved lack expertise or initiative. It is more often the case that they are pressed for time by other concerns resulting in them giving these issues scant attention. A further difficulty arises where an individual's lack of experience limits their personal horizon and dims their perspective of the problems ahead. Crises caused by poor quality have often overtaken contracts that appeared to be proceeding successfully, with the resulting delay and cost, undoing the supposed benefits that had been accrued.

This control ensures that the work done must be of required quality and durability. This can be achieved by conducting inspection from the source of supply of material up to the finished production. Major items of control before and during construction are verifications of soil characteristics, drawings and designs, structural safety, durability, checking the quality of materials, specifications, testing of materials and inspection of equipment.

The important step towards improving the quality of work is to ensure that all materials and fittings incorporated in the work are up to the standards laid down in the contract and Bureau of Indian Standards BIS specifications mentioned therein.

As far as possible materials approved by BIS should be incorporated in works. If BIS standards do not exist for a particular material, the same should be purchased from some standard manufacturer and got tested from approved test laboratories. In the construction plan development process, it is the clear responsibility of the designer to ensure all project elements are economical, accurate, properly prepared, coordinated, checked, and completed. In order for the project to consistently meet the needs and expectations of our citizens, quality must be as important as the schedule and budget.

Design personnel shall follow established design policies, procedures, standards and guidelines in the preparation and review of all design products. Design consultants are agents for the project with the primary responsibility for preparation of construction plans.

Consultants must ensure quality and adhere to established design policies. Every set of construction plans prepared by or for project are required to follow this process.

The Project Quality Control Plan details the proposed methods or processes of providing quality control for all work products. This plan will be kept current with the work requirements. Quality Assurance Certification Plans prepared by consultants for project must, at a minimum, follow the procedures set forth in the manual. The advantage of ISO are, it improves quality image of the company. It gives marketing advantage. It improves efficiency, reduces wastage. It ensures customer satisfaction.

What is ISO? ISO is a series of international standards for quality management and quality assurance system. ISO is a series which are continuously updated. ISOModel for quality assurance in production and installation. The difference between ISO and is essentially of design. If the organization designs buildings as per customer's requirements, then the organization can go in for ISO ISO quality system standard describes what the requirement of quality oriented system is. It does not set out special requirements.

Whether a company employs 10 or people, the principle of ISO can be applied. Reviewing contractor's compliance with specifications, requirement for construction methods and personals. The administrative functions will include: a Initiating, analyzing and approving design clarification or changes in contract documents. In the context of engineering structures. Quality control is a management activity applied to the construction processes to set purposes.

Purpose in this case being achievement of prescribed standard of performance and cost. To achieve optimum quality at minimum cost, we have to consider all the factors that help to build quality into a product or service. In the construction industry where majority of works are executed by the contractor the responsibility of quality control is in the hands of the contractor and he is responsible to the designer and the owner for this. The main problems facing the development of construction projects and structures are the technological advancement of their fabrication, the improvement of their quality, reliability and factory finishing-These problems can be solved by developing and applying efficient and continuous quality control at each stage of production and by testing products and structures using the latest instruments and machines.

The various process involved to be able to meet the above requirement should be cost effective. A quality system is a mechanism by which a company can organize and manage its resources to achieve, sustain and improve quality economically. Quality Systems are analogous to financial control systems, information technology systems and personnel management systems.

It is after all the time and effort expands in producing the initial system that a dangerous point is reached. The danger is that once the system is complete it will become a neatly packaged inviolate document.

This is the very thing that must be avoided and positive action must be taken to prevent it. A well directed quality auditing programme should be focused upon making upon the procedures more effective in terms of both Total Quality and company's aims. To conclude therefore it may be therefore it may be helpful to abstract the key point brought out in the previous chapters.

The key points are listed below, Better quality of work can be achieved by proper QC process at a minor cost when compared with the total cost of the project. QA can be achieved at the site by exact compliance to the construction specification standards. This can be achieved with a properly organized well equipped field laboratory at the site and centrally located at office. Quality Assurance is not an optional extra but, Philosophy that management must be committed to.

The construction specification in similar project to be executed in future should be modified based on lessons learnt during quality control exercised on previous projects. Quality of work largely depends upon the quality of materials to be used and workmanship. QC should be exercised at different levels such as preconstruction, during construction and post-construction.

As far as possible use of materials for structural members fabricated under controlled condition and strict supervision should be encouraged. Finally remember our Quality Assurance and Quality Control System is a live thing that must encourage a two-way flow of information, as it must change to improve. Related Papers. By David Oloo.

Сказал, что он взламывает коды каждые шесть минут и делал это даже пока мы с ним говорили.

The QA and QC maintain uniformity in construction process and ensure more economical utilization of materials leading to significant reduction in.


 Тебе больше нечем заняться? - Сьюзан метнула на него недовольный взгляд. - Хочешь от меня избавиться? - надулся Хейл. - Если честно - да, - Не надо так, Сью, Ты меня оскорбляешь. Глаза Сьюзан сузились. Она терпеть не могла, когда он называл ее Сью.

Мне не нужно напоминать. Через тридцать секунд она уже сидела за его столом и изучала отчет шифровалки. - Видишь? - спросил Бринкерхофф, наклоняясь над ней и показывая цифру.  - Это СЦР.

Тогда дело будет только за Дэвидом. Когда он найдет копию ключа, имевшуюся у Танкадо, оба экземпляра будут уничтожены, а маленькая бомба с часовым механизмом, заложенная Танкадо, - обезврежена и превратится во взрывное устройство без детонатора. Сьюзан еще раз прочитала адрес на клочке бумаги и ввела информацию в соответствующее поле, посмеялась про себя, вспомнив о трудностях, с которыми столкнулся Стратмор, пытаясь самолично запустить Следопыта.

 Слушай, я хотел спросить, - заговорил.  - Что ты думаешь об этом не поддающемся взлому алгоритме, который, по словам Танкадо, он хотел создать. У Сьюзан свело желудок. Она подняла голову. - Не поддающийся взлому алгоритм? - Она выдержала паузу.
