“…The very detailed and exacting Commissioning Process promoted in the US needs extensive interaction, communication and detailed record keeping amongst project participants, requiring all parties to be committed to work together. Cooperation and partnership amongst stakeholders is not a strong feature of Hong Kong construction practice [5,10,19,46], and attempts to implement full building commissioning may be too much of an imposition at this time. Where project participants are less concerned with resolving issues and are more inclined to passing on problems, the construction process is inevitably slowed and outcomes negated [37].…”

“…According to a survey by Fong et al [19] the principal factors contributed to construction delays were: improper site coordination and management of the electrical and mechanical installations, lack of timely decision making by the client, and defects identified during the fire services inspection by local authorities. Completion of FSI is prerequisite to obtaining an occupation permit for a building, with potentially significant economic losses if delayed.…”

Building life-cycle performance depends on the quality of process from planning through to demolition, including testing and commissioning. Commissioning costs depend on the scope of work and quality of management oversight, with the benefits also dependent on the persistence of the commissioning outcomes. Commissioning practices are evaluated for their effectiveness in terms of outcomes, costs and benefits, suggesting that Hong Kong buildings would benefit from enhancements to local practices.

“…Shebob et al (2012) employ the concept of severity index (SI) to rank the delay factors: As given in this equation, n corresponds to the frequency of the responses, and W and N have the same meaning as Equation 1. Other studies employ a combination of the relative importance as defined by Equation 1 and casespecific methods to quantify the relative importance of delay factors (Aibinu and Jagboro, 2002;Odeh and Battaineh, 2002;Frimpong, Oluwoye and Crawford, 2003;Fong, Wong and Wong, 2006;Zaneldin, 2006;Kaliba, Muya and Mumba, 2009). It can be verified that all of these studies use a Likert scale in their questionnaires to record the severity or weight of each delay factor.…”

2016). Studying the reasons for delay and cost overrun in construction projects: The case of Iran.Abstract: Undesirable delays in construction projects impose excessive costs and precipitate exacerbated durations. Investigating Iran, a developing Middle Eastern country, this paper focuses on the reasons for construction project delays. We conducted several interviews with owners, contractors, consultants, industry experts and regulatory bodies to accurately ascertain specific delay factors. Based on the results of our industry surveys, a statistical model was developed to quantitatively determine each delay factor's importance in construction project management. The statistical model categorises the delay factors under four major classes and determines the most significant delay factors in each class: owner defects, contractor defects, consultant defects and law, regulation and other general defects. The most significant delay factors in the owner defects category are lack of attention to inflation and inefficient budgeting schedule. In the contractor defects category, the most significant delay factors are inaccurate budgeting and resource planning, weak cash flow and inaccurate pricing and bidding. As for the consultant defects delay factors such as inaccurate first draft and inaccuracies in technical documents have the most contribution to the defects. On the other hand, outdated standard mandatory items in cost lists, outdated mandatory terms in contracts and weak governmental budgeting are the most important delay factors in the law, regulation and other general defects. Moreover, regression models demonstrate that a significant difference exists between the initial and final project duration and cost. According to the models, the average delay per year is 5.9 months and the overall cost overrun is 15.4%. Our findings can be useful in at least two ways: first, resolving the root causes of particularly important delay factors would significantly streamline project performance and second, the regression models could assist project managers and companies with revising initial timelines and estimated costs. This study does not consider all types of construction projects in Iran: the scope is limited to certain types of private and publicly funded projects as will be described. The data for this study has been gathered through a detailed questionnaire survey.Hamed Samarghandi et al. 52/PENERBIT UNIVERSITI SAINS MALAYSIAan important role as a major driving force in the growth of several other sectors in the economy, including but not limited to mining and natural resources extraction, transportation and logistics, insurance, consultation and management, and even education and training (Assaf and Al-Hejji, 2006). According to the statistics provided by the Central Bank of Iran, the construction sector has annually absorbed more than USD 13 billion in direct private investments between 2002 and 2014.Unfortunately, construction project delays are very common in Iran.

A Fire Safety Evaluation System for Prioritizing Fire Improvements in Old High-rise Buildings in Hong Kong

Fire safety in old high-rise buildings is of great concern to the general public as a result of several big fires occurred over the past 10 years. A fire safety evaluation system is essential for building engineers to quantify the fire safety level, to identify the measures to be improved and to schedule the corresponding improvements. Together with a scoring system with weighting factors derived for local buildings, this paper proposes a universal fire safety evaluation (FSE) checklist for fire safety level quantification and improvements prioritization in old high-rise buildings. In a survey, the fire safety levels of 122 old high-rise buildings in Hong Kong were quantified using the scoring system. The survey results showed that only less than 5% of the inspected samples reached the standard required for life safety. The FSE checklist was then applied to prioritize the improvement works of 10 selected buildings with the lowest scores.
