Authors: Ndagi A , Umar A A , Hejazi F , Jaafar M S 
Published: November 2019

Abstract
As concrete structures age, concrete quality tends to deteriorate for reasons which include frost damage, acid attack, sulphate attack, fire damage or as a result of bad construction practice. Thus, these effects develop as distresses thereby undermining the general performance of a structure. Result from Ultrasonic Pulse Velocity (UPV) test is inevitably affected by the properties of the concrete under test which contributes in abating the test results. Hence, this paper reviews the UPV test by considering arrangement options and common factors which affect the result obtained from the test and attempts to make recommendations to obtaining reliable results. Out of several conclusions drawn, it is worthy to mention that the direct arrangement for conducting UPV test was found to be the most suitable. In addition, the UPV test was learnt to be poor in assessing concrete strength but when combined with a Rebound Hammer Test, which is also Non-destructive, the result is substantiated.

Published: November 2019

Abstract
Beams with opening are increasingly applied as alternative passages for services, such as electrical, plumbing, and telecoms. However, opening efficacy on the beam behavior under loading has been rarely explored. This study evaluates the effects of a square opening in the solid beam with different sectional sizes on the performance of reinforced concrete (RC) beams under flexural load. Two types of materials for the beam section are considered: high-strength concrete (HSC) and ultra-high-performance concrete (UHPC). The finite element model is developed to simulate simply supported RC beams subjected to flexural load. Four beams are modeled using HSC and UHPC with square openings in different sectional sizes, and nonlinear analysis is conducted by applying incremental load. Furthermore, a parametric investigation is resulted to evaluate the ability of various sizes of opening on the performance of beam under flexural load. Analysis results show that the created web openings in solid beam decrease the capacity of beam. However, solid small opening in beam can resist nearly the similar load of solid beam without any opening. Moreover, the load capacity of UHPC beams with opening is higher than that of HSC beams with opening.

Abstract
Lateral boundary condition (LBC) is one of the key features included in the Weather Research and Forecasting (WRF) simulation model. Nowadays, numerous LBCs were developed with various spatial (grid) and temporal resolutions for a wide range of applications. Choosing the most suitable LBCs to ensure appropriate representation of climates should be properly conducted. Thus, this paper analysed the effects of the LBC resolutions on the regional climate downscaling for heat island studies. The comparisons were made on the performance of respective LBCs to regenerate the near-surface temperature distributions within the Kuala Lumpur city. NCEP GDAS/FNL 0.25 Degree Global Tropospheric Analyses dataset with higher spatial and temporal resolution was found to perform better than the other LBC during intermonsoon season. However, both datasets were determined to give reliable representations of urban climate condition within the city as both datasets depicted close results in determining the impact of urbanization on the thermal environment.

Abstract
In Malaysia, building refurbishment is fast becoming an important sector in the construction industry. Refurbishment projects are generally characterised to be of higher risk, more complex and needs greater coordination than new build. As briefing stage is one of the main source of design information, meeting the clients’ requirements in briefing stage and working within the complexities of existing building may pose a difficult task to produce the required information for designers to start design. Quality of required design information in refurbishment projects is affected by level of complexity factors in briefing stage. Affected design information is one of the considerable factors, which leads to refurbishment projects performance failure. Therefor this research aim is to assess the level of potential complexity factors in briefing stage of refurbishment projects that hinder designers to acquire the required information to start design. This research employs the quantitative approach, that is, a questionnaire survey targeted at experienced architects and interior designers involved in refurbishment projects within Klang valley area to provide the data in investigating the level of complexities in briefing stage of refurbishment projects. The result indicated that the key complexities in briefing stage of refurbishment projects can be divided into three main categories; Lack of document, Project characteristic and Client’s characteristic.

Published: November 2019

Abstract
New Zealand has been affected by a number of natural disasters in recent years. One such example is the 2010 Christchurch earthquake that led to significant impacts to businesses, buildings and critical infrastructure. Construction organisations play an important role in reconstruction programs, and communities rely on their services, particularly post-disaster. Improving the resilience of construction organisations to natural disasters not only minimises the negative consequences to their organisations post-disaster and enhances their organisational performance during business as usual, but also helps to improve community resilience. However, very few studies have developed the concept of organizational resilience and none specifically in the construction sector. This paper identifies strategic resilience indicators for construction organizations. Triangulation analysis of the five studies, in-depth interviews and questionnaire surveys revealed leading indicators of organizational resilience which can help to develop a resilience framework for construction organizations. The findings suggest that the construction industry needs a framework that fosters resilience which itself can potentially enhance organisational capacity to recover quickly after a crisis or disaster.
