THE IDENTITY OF OPEN SPACE: ADAPTING FROM THE MODEL OF TRADITIONAL NEIGHBORHOOD CENTER
No full text The City form consists of some different elements, which have been joined in the functional and spatial form. If these elements have an appropriate spatial organization the strong coherence is created among them. In the traditional urban spaces, most of the times, this spatial regularity among city elements is the result of thoughtful developed urban patterns. Many non-local agents influence on the form of new cities while the forming of traditional urban spaces depends on the morphology of the site, the historical background and the culture of local people. In this way, we were looking for some of the important researches by focus the open spaces and exactly neighborhood centers in Iran. We also choose the analysis literature review for our methodology. All our attention was on two case studies in Iran (Tehran and Shiraz). In this paper, we tried to find ways to evaluate the value of neighborhood centers in the traditional urban for fulfillment to sustainable development urbanism. Urban planners and designers should find out the secret of the traditional cities' sustainability and the factors which make the responsive environment, and think that what the reasons prevent using them in contemporary cities. And then they should find a way to update those factors based on today demands, and design new patterns according to old one
EVALUATION OF THE CAPITAL BUDGET PLANNING PRACTICE OF CONTRACTORS IN THE CONSTRUCTION INDUSTRY
Full text linkPoor and unrealistic budgeting has been traced to the inefficiency and neck-deep poverty of contractors in the construction industry, this attributes to the economic decline of firms and capital disappearance in the industry. This research work seeks to evaluate the capital budget planning practice of contractors in the Nigerian construction industry. The research made use of questionnaires for data collection and the statistical tools employed in the analysis are frequency tables, percentages, cumulative percentages, and mean score ranking. The variables used for the evaluation include long-term capital budgets, capital budgeting manual/written procedures, formal bodies responsible for screening and reviewing projects, capital budgeting personnel and regular minimum rate of return review. The study revealed that about 50% of contractors do not make plan for long-term capital budgets and therefore cannot handle large projects. It is recommended that contractors make plan for long-term capital budgeting and devote more personnel to capital budget planning to ensure that they can handle the numerous large construction projects in the industry
INVESTIGATION ON THE CAUSES OF VARIATION ORDERS IN THE CONSTRUCTION OF BUILDING PROJECT – A STUDY IN THE STATE OF SELANGOR, MALAYSIA
Full text linkThis paper investigates the most significant causes contribute to the variation orders in the construction of building projects in the States of Selangor Malaysia. Data was collected from questionnaires survey which is based on the literature reviews and also provisions in the ‘Persatuan Akitek Malaysia” (PAM 1998) standard form of building contract that are associated with the variation orders. The data were analyzed by using mean score method and rank to formulate the findings. The result from questionnaires survey revealed three most significant causes variation orders which are: ‘Change of plan by owner’, ‘Substitution of materials by owner ’, and ‘Changes of design by consultant’. The finding concludes that owner is the major source of the variation orders in construction of building projects and suggested that owner should have adequate planning and recourses before initiating a project in order to avoid variation order during the construction stage
FACTORS INFLUENCING REWORKS OCCURRENCE IN CONSTRUCTION: A STUDY OF SELECTED BUILDING PROJECTS IN NIGERIA
Full text linkRework has become a menace in Nigerian construction industry and it has not been given required attention, it contributes to time and cost overruns in project. Hence, to improve the performance of projects the research work evaluated rework in some selected building projects in Niger State. The work identified some factors contributing to rework which was categorized under three main headings; technical, quality and human resources factors to actually dig down into the casual of rework. A structure questionnaire was self administered on projects identified to have experienced rework amongst the selected projects and these were ranked according to their perceived degree of severity. Response was further condensed using factor analysis to group the variables into identifiable factors and thus analyzed. The study revealed that sub-standard services rendered by professionals and lack of commitment to quality in term of project delivery by stakeholders are the main source of rework. Therefore, it was recommended that an improvement and total commitment to quality of services render and assurance would lead to a reduction in the occurrence of reworks as revealed by the research
IMPACT OF NON-IMPLEMENTATION OF TIME, COST AND QUALITY MANAGEMENT PROCEDURES IN THE NIGERIAN CONSTRUCTION INDUSTRY
Full text linkThe study is an assessment of time, cost and quality management in the Nigerian construction industry, and its objective is to examine the impact of non-implementation of these factors in the Nigerian construction industry. This study is limited to the view of a convenient sample of professional i.e. Architects, Builders, Quantity Surveyors and Engineers. The method used to collect data were questionnaire and interview while the data collected were subjected to descriptive statistical analysis using percentage, mean score and frequency. The study revealed that the impact of non compliance with time, costs and quality management procedures is building collapse as evident in the Nigerian constructions industry today. Others includes high cost of construction, which make building constructions very high thus leading to project abandonment which constitute nuisance to the built environment and this can lead to lost of public confidence in the industry. The study recommends that modalities should be put in place by government and concerned professional bodies to guide against fraud, the relevant authority like SON (Standard Organization of Nigeria) should wake up from slumber and come up with standards for construction component and lastly the National Building Code should be adopted for use in the building construction in all its ramifications
The Role and Function of Thermal Insulation in Architecture
No full textWith movement of cities toward a more industrial urban structure, they need of green environment is increasing. One of the solutions is creating the green roofs which the interest on them is increasing. However, having a green roof requires some technical guidelines to provide the desired environment. The technical guidelines for instruction of green roof aim to provide an adapted, environmental friendly and suitable material for offering the optimal operation. This focus of this document is mainly on the technical aspects of the material in need for insulation, roofing membranes and protection material, moisture-retention material and water proofing
