“…Moreover, metals used in construction usually experience a number of different processing techniques, such as heating, coating with nonmetallic substances, mixing with other metals, and reaction with certain chemicals. The whole process requires high fuel consumption and produces CO 2 emissions and other pollutants that can affect the environment (Yahya et al., 2016).…”

The population of Timor deer (Rusa timorensis), an Indonesian endemic, continues to decline in its natural habitat, so captive breeding could become a source of individuals to bolster wild population. Support for captive breeding programs may be stronger if captive breeding also provided meat for human consumption. Thus, sustainable captive yields could be expected to support both conservation interests and food needs. The aim of this research is to evaluate the environmental impact, based on global warming potential (GWP), of two Timor deer breeding systems, that is, a farming system and a ranching system, in West Java, Indonesia. Life cycle assessment methodology was used for the evaluation to gain a cradle-to-gate perspective. The functional unit used was 1 kg of Timor deer live weight in captivity. The main result of the study indicated that the GWP per kg of Timor deer was estimated at 17.30 kgCO2eq (farming system) and 17.60 kgCO2eq (ranching system). The largest GWP in both systems was derived from cultivation activities and infrastructure development. In general, there is no significant difference in the GWP of the two breeding systems studied. This was due to the similar overall management adopted by the two breeding systems, especially the use of food types and infrastructure materials. Currently, the environmental dimension, especially the emissions from Timor deer breeding activities, is not a major concern, but in the future, breeding management should pay attention to the efficient use of the food and infrastructure to make it more environmentally friendly.

“…They are categorised as material delivery (transportation and handling); overhead cost reduction during construction; preliminary cost reduction; supply; variation management; plant and equipment hire (depreciation), and payment of sub-contractors (Yates, 2013;Jayamathan and Rameezdeen, 2014;Khanh and Kim, 2015;Yahya, Boussabaine and Alzaed, 2016). The waste category in this study can comprise both physical and non-physical wastes (Sandhu, 2014;Ajayi et al, 2016;Chatziaras, Psomopoulos and Themelis, 2016;Yahya, Boussabaine and Alzaed, 2016). For instance, waste arising from material handling and transportation are physical, but waste arising from overheads are non-physical.…”

PurposeContinual cost reduction of overhead costs of building projects can realign the concept of post-contract cost control towards value-driven construction projects and stakeholders’ satisfaction. This study synthesised and analysed the viable continuous improvement measures critical for waste reduction during the execution phase of a building project.Design/methodology/approachA review of existing literature facilitated a list of continuous improvement measures. This literature review findings enabled a Likert-scale questionnaire which was administered to two-hundred and fifty (250) small- and medium-scale construction companies (SMSCC) in Nigeria. Multiple linear regression statistical tests deduced the significant cost reduction measure from which a causal loop diagram was designed to indicate continuous improvement measures during the execution phase of a building project.FindingsCogent construction activities associated with overhead costs were deduced from the statistical tests as being payment of suppliers and sub-contractors and purchase orders. An all-inclusive casual loop model for cost reduction through waste minimisation in construction projects as a viable oriented mechanism for meeting clients' requirements was developed.Practical implicationsThe causal loop continuous improvement model recognised external and internal factors which are crucial for SMSCC to focus on for their organisational growth and performance enhancement.Originality/valueA focus on non-physical waste in construction organisations potentially addresses behavioural challenges for continuous improvement.

“…It is essential to incorporate the green assessment criteria into BIM standards and guidelines as they deal with site selection during the planning stage, green building materials selection during the design stage, energy efficiency use during the operation phase, and air ventilation during the maintenance phase, which is needed to improve built-environment sustainability (Aspinall et al, 2012). Yahya et al (2016) also urged that future work must examine the way that ecoindicators can be included in projects via strategies of BIM implementation. The inclusion of green assessment criteria in BIM standards and guidelines could compel designers, contractors, researchers, and BIM vendors to establish a BIM profile that matches the sustainability requirements.…”

Building Information Modelling (BIM) is a digitalised technology under a collaborative working platform. Certain aspects of sustainability have been highlighted in recent BIM studies; however, no prior in-depth review has focused on BIM standards or guidelines and its uses for sustainability. This paper provides a mixed review to determine the current stateof-the-art BIM development for sustainability. A systematic review approach was adopted to analyse two main sources of literature, namely, BIM standards and guidelines; and peerreviewed academic publications. The result reveals that although there has been a significant amount of research and development about the use of BIM during various project phases, little work has been conducted about how it could be applied in refurbishment and demolition. Certain significant insights and implications have been uncovered, namely: (a) new BIM tools are required for assessing sustainability criteria; (b) the need for improved interoperability among BIM software and energy simulation tools; (c) BIM uses into various aspects of refurbishment and demolition have to be streamlined; and (d) an innovative procurement system is needed to adapt social sustainability into the project.
