Structural overdesign of villa in Oman
2016
Residential projects represent the largest section of the construction industry in Oman. It is widely claimed that designers in Oman tend to unnecessarily overdesign structures, thereby aggravating construction costs. The aim of this research was to investigate the existence and extent of structural overdesign through the investigation of 31 villas which were approved by Muscat Municipality between 2000–2010. The specified villas were structurally redesigned based on the British Code of Practice using the same geometry and material strengths recorded in the drawings. The required reinforcement resulting from the redesign work was compared with the provided reinforcement as per the drawings. The results showed clear cases of extra reinforcement in almost all villas. The difference between required and provided reinforcements in the villas ranged from 2.3–104.8%, with an average of 48.5% and a standard deviation of 24.0. The required and provided weights of reinforcement per square me...
SHS Web of Conferences, 2014
The purpose of this study is to describe the experiences of architects and civil engineers in the Sultanate of Oman regarding building maintenance during the design of public buildings. This exploratory and descriptive study used a qualitative approach, drawing data from focus groups in particular, to develop a rich and in-depth description of the designers' building maintenance experiences. Structured interviews were conducted with 15 participants from architecture and civil engineering fields, from which, the interviewees shared the viewpoint that maintenance functions entirely separate from the design and construction process itself, but that it is, in fact, an integral part of the design process and post-occupancy stage. The designer should plan for sufficient maintenance for the whole building life cycle. However, some elements are more difficult to maintain in Oman than in other regions such as roofs, facades and the substructure of buildings. The results showed that salt is the most challenging environmental factor that could cause building defects. This was followed by solar heat, moisture from below ground and, lastly, rain. Most of these defects occurred during the buildings' post-occupancy phase and were related to inappropriate or poor design. The results also suggested that deficiencies caused by thermal expansion came in the form of cracks, followed by paint decay, dampness, and staining.

Causes of Discrepancies between Design and Construction in the Pakistan Construction Industry
Journal of Construction in Developing Countries
In the building construction, discrepancies frequently occur between the design and construction pertaining to architectural details, structural details, materials and quality of construction. The objective of this paper is to identify the major causes of discrepancies in building construction from the viewpoint of the project stakeholders. A questionnaire is utilized that contains sixty-five potential causes of discrepancies, classified into four categories including the design, tendering, construction and overall project phases. Data were obtained from Pakistan and the response rate was excellent (80.6%). Collected data are analysed and important causes of discrepancies are identified. Results indicate that the provision of incomplete data to designers, lack of interest by approving authorities to carefully check the design, and owner-proposed changes due to financial problems, are the top three important causes of discrepancies. Insights and discussion are provided in the paper. This work provides a basis to minimize discrepancies in the construction industry and consequently helps in reducing rework, delays, and defects in construction.

Background: Residential buildings are an essential and significant satisfaction pillar for the human’s life to ensure a safe and durable residence. In addition, due to the rapid development and population growth in the Gaza Strip, many residential buildings and housing projects are being implemented in a short period of time especially after Gaza conflict during the year 2014. Therefore, various errors and defects are anticipated to rise during the design stage. Objectives: The aim of this paper is to identify and rank the factors affecting the occurrence of the defects in the structural design stage of residential buildings in the Gaza Strip. Methods: A survey was conducted for 134 respondents randomly selected as engineers, working for engineering consultant offices as designers, supervisors and projects managers in Gaza Strip. Results: The study reveals that the three most effective groups of factors are; the consultant administration and staff group, the drawings preparation gro...
A Study of Design Performance of Refurbishment Projects in Malaysia
Journal of Asian …, 2010
The refurbishment sector has the potential to keep growing and contribute to the growth of total Malaysian construction output. The increased number of obsolete and deteriorating buildings, coupled with the limited land for new development will contribute to increased demand for refurbishment works in Malaysia. However, the performance of refurbishment projects in most developed countries is unsatisfactory. One of the sources of unsatisfactory performance is related to design problems. This study analyses the variables that could be used for measuring design performance and reviews design performance of refurbishment projects in Malaysia. The study concludes that the design performance of refurbishment projects in Malaysia is used in three-quarters of refurbishment projects. The percentage of completeness of design before work starts on site was more than 80 percent. The additional construction cost attributed to design changes during the construction stage was more than 20 percent of the original estimated cost.
RECENT PRACTICES OF ANALYSIS AND DESIGN OF HIGH-RISE BUILDINGS IN KUWAIT (CASE STUDY
Proceedings of 2nd ACI-Kuwait Chapter in Kuwait , 2007
The main concern of this paper is to provide an overview of the current analysis and design methodology for reinforced concrete high-rise buildings. A case study of residential complex consisting of two new 30-floor towers located in Kuwait city is presented to demonstrate the most significant factors to be considered to ensure the building is designed to have sufficient strength to withstand ultimate (factored) gravity (dead plus live) and lateral (wind plus seismic) loading and sufficient stiffness to limit deformations and lateral drift to be within the acceptable range to verify the occupancy comfort level. Building code procedures are based on general assumptions, are usually but not always conservative, and do not provide accurate wind loads because of exposure conditions, directional properties of the wind climate, complex geometry shapes, torsion, aerodynamic interactions, and load combinations. Wind tunnel tests, which are capable of more accurate load definitions have become faster and more economical as a result of improved analysis and design methodologies. Finally, recommendations for analysis and design of reinforced concrete residential high-rise buildings in Kuwait are introduced.
Comparison Study for the Structural Behaviour of Concrete Office and Residential Buildings in Kuwait
Modern Methods and Advances in Structural Engineering and Construction(ISEC-6) - Conference in Zurich, 2011
The main objective of this paper is to provide a comparison study of the impact of the different design parameters on the structural behavior of low/medium/high rise office and residential concrete buildings aiming to deepen structure and architect understanding of such type of buildings. The study is emphasized only on Kuwait city design parameters for wind. A regular symmetrical layout plan is selected for buildings with different height ranging from five to fifty typical floors. Three dimensional finite element techniques using ETABS software is used for analysis and design of different buildings presented in this paper. Serviceability study is performed to ensure that both lateral drift and peak acceleration are within the acceptable limits. Ultimate strength study is carried out to verify that all structural elements can withstand factored gravity and lateral loading in a safe manner. Building slenderness ratio, core size and location are the parameters studied in this paper since they are the key drivers for the efficient structural design of these buildings. Analysis results are presented and discussed to demonstrate similarities and differences between office and residential buildings structural behavior. Finally, conclusions are summarized as guidelines for the structural professions to be considered in the design of such buildings in Kuwait.
