“…The various levels of free expansion ratio measured by different combinations of design recipe parameters were obtained from the orthogonal table (Table 3), and is the average value of the horizontal tested results corresponding to different recipes; the smaller the value, the lower the average free expansion ratio (Guo and Wei, 2016). The average value of the horizontal tested results ( ) cured over design days can be obtained using Equation (3).…”

The deformation properties of cemented tailings backfill (CTB), especially prepared from sulphidic tailings, are valuable for the estimation of design parameters for underground stope filling as well as for numerical simulation. In this paper, the effect of curing time, sulphur content, cement dosage and solids concentration on the free expansion ratio of CTB specimens was investigated using an invented lab apparatus called "free expansion measuring instrument". The backfill recipe (sulphur content, binder dosage and solids concentration) and curing days had significant influences on the expansion performance of the CTB. The results indicated that with the change of sulphides, the free expansion ratio (FER) showed no obvious growth at the curing of 28 days. However, after the curing of 120 days, FER increased from 4.96% (S: 4%) to 9.61% (S: 20%). As the solids concentration increased, the FER also rised. And this growth was distinctive only when the solids concentration is relatively high (65~75%) and at the long-term curing time (120 days). The proportions of binder and the obtained FER clearly show a sub-linear and proportional relationship. Increasing the amount of binder (8~16%) could not restrict the increment of expansion ratio, and ultimately the CTB specimens would generate cracks and collapse.

“…By using BIM-based Building Energy Simulation (BES) tools, Kim and Woo [19] compared several design alternatives based on their energy consumption. Guo and Wei [20] also investigated the energy-savings of a building with an alternative building envelope by using these tools. Some other BES tools can use BIM models as input by importing them under specific data formats.…”

The UK government made significant commitments to upgrading the energy efficiency of seven million British homes by 2020, aiming at reducing carbon emissions and addressing fuel poverty. One alternative to achieve better energy performance in existing houses is retrofit. However, there are difficulties associated with retrofitting social housing. It is currently challenging to compare scenarios (retrofit options) considering costs, potential energy efficiency gains, and at the same time minimising disruption to users. This paper presents a Building Information Modelling (BIM) protocol aimed to support decision making by social housing owners. It adopts BIM to simulate alternative retrofit options, considering: (a) potential reductions in energy consumption, (b) 4D BIM for retrofit planning and reduction of users’ disruption and (c) simulation of costs. A what-if scenario matrix is proposed to support decision making in the selection of social housing retrofit solutions, according to client and users’ needs. A case study of the retrofit of a mid-terrace house is presented to demonstrate the workflow. The main output of the work is the BIM protocol, which can support client decision making in diverse social housing retrofit projects, considering all three elements (energy simulation, planning for reduced disruption and cost estimation) in an integrated fashion. Such an integrated approach enables clients to make better informed decisions considering diverse social housing retrofit options through a simple process using readily available BIM technology.

“…Lu et al (2014) concluded that a cost saving of 6.92% (490.86 HKD/m 2 ) was achieved via cost benefit analysis conducted in a sample BIM project. Guo and Wei (2016), on the other hand, utilized BIM with an energy-simulation system to conduct an energy-consumption analysis that provided more comprehensive information for optimal design selection.…”

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.
