The quality of any finished project in the construction industry relies mainly on the specifications written for that project. The specifications are benchmarks for the quality of the project, which should be referred to during all phases of the project. Successful specifications are normally associated with accuracy, clarity, coverage of all clauses, precession and the effectiveness of the description of the materials and methods of fixing. On the other hand, poor specifications often result in delays in handing-over, escalation of prices due to variations, disputes, high penalties, loss of trust and compromise in the quality of the finished project. The construction industry in Bahrain often suffers from poor specifications. In order to determine the severity of the problem, a questionnaire survey was undertaken to analysis the present standard of specifications used in the construction industry in Bahrain. The outcomes of the survey revealed major setbacks in the standard of the existing specifications such as inappropriate repetition, excessive conflict, unclear and uncompleted clauses with little precession. The majority of respondents called for a change in the situation. Improvement of quality has become a major challenge faced by the construction industry and can involve, reducing cost solving problems of rework, reducing maintenance cost and improving the life cycle value of the buildings. Total Quality Management has become one of the best solutions to overcome the problems, and specification could be used as a gate to introducing TQM to the construction industry. Specifications are approach to setting the standard of quality for any construction project, and used as a tool to get design and construction teams committed to the projects quality standards through all stages of the construction process. The overall afin of Us thesis is to develop a framework for implementing Total Quality Management (TQM) in the construction industry in Bahrain, by developing a dynamic specifications model which will help to improve performance in the construction industry, improve consultant-client- constructor- supplier chain relation, control the budget of the project and reduce disputes, claims and variations in the construction industry.

In order to reach the economic scale, reduce unit cost and to enhance the international competitiveness, China Steel Cooperation constructed a subsidiary - Dragon Steel Cooperation, a 5-million-ton integrated steel plant nearby Taichung Harbor. Starting from iron-smelting, steel-making till steel-rolling, each step follows one another. If any of the steps occurs a problem, the whole production will be affected. The quality of the new construction is related to the life cycle of the equipments, the stability of the operation and the quality of the products. Further more, if the new construction is imperfect, there might be plenty of accidents, such as public safety, environment issues, protest from the inhabitants, etc. The influences could be huge. The main quality influences of the new construction work are low bids from the contractors, shoddy work and use inferior material during the construction, lack of control, welding problems, etc. According to the above main factors, we listed 20 secondary factors, e.g. bad financial situation, vicious competition, budget shortfalls, etc., and use analytical hierarchy process to find the relationship between them. In this thesis, there are in total 32 people have been interviewed, 8 of them are first-line supervisors (the up, middle and downstream of the steel plant, from steel-smelting plant, steel-rolling plant, public facility department to civil department.) Meanwhile, 10 senior executives are also interviewed; relevant literatures are used as related inference. Via this analysis, the most important factor of influencing the welding quality of new construction work is ¡§welding problem¡¨ with 0.297 rating point. Analyzing the third layer factors of low bids rating, the highest point is ¡§vicious competition¡¨ with 0.354. In shoddy work and use inferior material factor, ¡§changing subcontractor frequently¡¨ is the highest with 0.491 rating point. In false inspection, the ¡§progressing pressure¡¨ is the highest with 0.378 rating point. In welding problem, the ¡§construct without drawing¡¨ is the highest point with 0.371. In other factors, ¡§defected raw material¡¨ is the highest with 0.275 rating point. If the above problem solved, the welding quality in new construction work will improve tremendously. Keywords: non-destructive testing, quality of construction, new construction work, turnkey contractors, defect.

This thesis deals with the legislation and control the production of steel constructions. The main aim of thesis is to develop the necessary technical regulations and documents to ensure compliance with technical requirements for the manufacture of steel constructions which are in accordance with legislative regulations and technical standards.

Quality and quality management have gained importance in the construction industry also due to losses of life and property. For high-quality buildings, the amount of defects during the construction works must be reduced. Thus, it is important to determine the defects which lead to low quality in the construction projects / and architectural, structural and constructional standards to measure some indicators of quality like workmanship, design of components and usage of correct and highquality materials. Therefore a systematic approach is required to achieve good standards both in design and construction. CONQUAS quality assessment system and Six Sigma quality management system are systems that could provide this systematic approach. The objective of this research is to evaluate the quality in mass-housing projects via Six Sigma. Thus, level of construction quality of the three houses in ODT&Uuml / KENT housing units in Turkey were assessed through Six Sigma with the contribution of CONQUAS quality assessment system. CONQUAS was used for determination of standards, whilst Six Sigma was used for data analysis. After the evaluation of interviews with contractor, site-supervisor, occupants and visual observations, defects and their reasons were determined. Reasons of poor quality in ODT&Uuml / KENT housing units were listed as firstly poor workmanship, then improper or of poorquality material usage and lastly problems in design of detailing. Despite different construction dates of units studied, the results show that nothing was learned from the previous mistakes and same defects were repeated. This shows the importance of a system providing feedback and evaluation of quality level of a construction project and quality improvement efforts of the contractor, and measuring the progress over time like Six Sigma.

Thesis (MEng)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: Construction of structural concrete frames may take place by using either cast in-situ or precast methods. With the cast in-situ method, these elements are constructed on the construction site as needed. Precast construction on the other hand is more resembles a line. The elements are constructed in a precast yard in a systematic fashion and once completed, they are taken to the construction site where they are to be erected. This study identifies the aspects and attributes which influence the quality of concrete during the construction phase of these two construction methods. The study is independent from the conceptual or design phase. Information regarding these aspects and attributes were obtained from literature and from contractors in industry through interviews and site visits. The literature review also focuses on quality management techniques and factors that influence quality in the construction environment. The information obtained from the site visits and literature was used to design a survey which was sent out to a number of respondents. A comparison between in-situ and precast construction was made based on the results of the survey. The synthesis of the research findings can be used by project teams to help them decide on the choice between in-situ and precast construction. It was found that precast construction is better for durability, and fitness for purpose is less complex for the in-situ solution. Recommendations for future studies are provided at the end of the document. / AFRIKAANSE OPSOMMING: Konstruksie van beton struktuurrame kan plaasvind deur die gebruik van in-situ of voorafvervaardigde metodes. Met die in-situ metode, word hierdie elemente op die terrein gebou soos benodig. Tydens voorafvervaardigde konstruksie aan die ander kant is die konstruksie soortgelyk aan 'n produksielyn. Die elemente word gegiet in 'n voorafvervaardingsterrein in 'n sistematiese wyse, en sodra dit voltooi is, word dit na die konstruksie terrein geneem waar dit opgerig word. Hierdie studie identifiseer die aspekte en eienskappe wat 'n invloed op die kwaliteit van beton het tydens die konstruksiefase van hierdie twee konstruksie metodes. Die studie is onafhanklike van die konseptuele of ontwerp fases. Inligting rakende hierdie aspekte en eienskappe is verkry uit die literatuur en van kontrakteurs in die bedryf deur middel van onderhoude en besoeke. Die literatuur fokus ook op die gehalte, bestuurs-tegnieke en faktore van gehalte in die bou-omgewing. Die inligting is verkry deur ‘n vraelys wat aan 'n aantal respondente gestuur is. 'n Vergelyking tussen in-situ en voorafvervaardigde konstruksie is vervolgens gemaak op grond van die resultate van die opname. Die sintese van die bevindinge kan gebruik word deur projek spanne om hulle te help besluit oor die keuse tussen in-situ en voorafvervaardigde konstruksie. Die resultate dui daarop dat voorafvervaardigde konstruksie beter is vir duursaamheid, maar passing op terrein is minder kompleks vir die in-situ oplossing. Aanbevelings vir toekomstige ondersoeke word aan die einde van die studie gemaak.

Thesis (MTech (Quality)--Cape Peninsula University of Technology, 2009 / Irrespective of the nature of organisations, they all face a certain amount of uncertainty and risk. In order to maintain resilience, competitiveness and performance, organisations must have a system in place to manage the risks associated to their organisations. The challenge is to determine how much risk and uncertainty is acceptable, and how to cost effectively manage the risk and uncertainty while meeting the organisation‟s strategic and operational objectives. For many large organisations, quality or so called „customer perceived quality‟, has become an issue of survival. Furthermore, increased competitiveness is necessary in order to become the obvious choice for the customer. Corporations must have long term goals and Quality Management Systems serve as organised mechanisms to manage quality, effectiveness and competitiveness involving every one at all levels of the organisation. An understanding of culture in organisations can thus offer insight into individual and group behaviour, and leadership. Furthermore, it can help to explain not just „what‟ happens in an organisation, but „why‟ it happens. Companies view culture as something to be influenced to achieve organisational goals of productivity and profitability. Attempts to change the culture of an organization, may meet with varied levels of success. The emphasis on quality building products, have been the focus of the construction industry in South Africa. As a supplier of extruded aluminium profiles to the building industry, Hulamin Extrusions is also faced with typical challenges representative of the industry and as a result, the following aspects would be subjected to research scrutiny: Introduction of a Quality Management System. The challenges of organisational culture. The need for change management. Facilitating the implementation of the system. Continuous Improvement. The researcher anticipates finding ways to improve organisational culture, which in turn would facilitate quality improvement within the organisation.
