This research concerns the delivery of sustainable building projects. These projects are defined as those which either attempt to achieve green ratings or are claimed to address certain sustainability issues. A key focus is to examine how the client's vision for sustainability is achieved or compromised by the practicality of construction. Two sustainability rating systems, the Australian Green Star and the Living Building Challenge from the U.S. are discussed. This research examines two projects; one university multipurpose building (SMART Infrastructure Facility); and an advanced research facility, the Sustainable Buildings Research Centre (SBRC). The methodology used is semi-structured interviews of key participants and stakeholders for the two university building. The outcome of this research indicates that environmental rating systems are useful tools to construct reasonably sustainable buildings. Many interviewees, however, believe that for their next projects the concern would be to continue to construct sustainable buildings but not necessarily by following the strict criteria and reporting requirements of the environmental rating system.
Rasekh, H 2017, 'The shear performance of cable bolts in experimental, numerical and mathematical studies'.
The behaviour of encapsulated cable bolts in the rock mass has been studied in the past to determine the load transfer capacity and their ultimate tensile strength. Past studies were mostly based on pull-out tests because of the ability of pull-out tests to be conducted both in the laboratory and in the field. Thus, a number of experimental and analytical models are available to determine the load transfer capacity of cable bolts mainly in pull-out conditions. On the other hand, studies on the shear performance of cable bolts are limited and are mostly based on experimental studies, which do not accurately simulate the real shear performance of cable bolts. The shear behaviour of cable bolts is significantly affected by pretension load, cable bolt surface profile type, ultimate tensile capacity, rock mass strength and cementitious grout or chemical resin properties. None of the past research studies investigated the shear behaviour of various types of fully grouted cable bolt with varied pretension loads subjected to shearing. This thesis is concerned with the study of the shear behaviour of cable bolts. Shear tests have been carried out using both single and double shear apparatus (with and without contact between concrete block surfaces).
Ten different types of cable bolts; plain and indented Superstrand, indented TG, plain and indented SUMO, twin Garford, Secura HGC, plain MW10 and spiral MW9 and plain 19 wire 21.7 mm were tested at different pretension loads, 0 t to 10 t and 25 t. Different resin and cementitious grouts were used to assess their impacts on the cable bolt shear strength. Concrete blocks with Uniaxial Compressive Strength (UCS) of 40 MPa were used in experiments to maintain consistency. Three different sets of tests were conducted to determine the shear strength and failure characteristics of various cable bolts used in Australian mines. Therefore, these three sets of tests were:

Rasekh, H 2014, 'Delivering the Vision of Sustainable Buildings'.
This research concerns the delivery of sustainable building projects. These projects are defined as those which either attempt to achieve a green rating or try to address certain sustainability issues. Two sustainability rating systems, Green Star from the Green Building Council of Australia and the Living Building Challenge are considered.
The research examines a number of completed projects and looks at one project nearing completion. These include 18 residential buildings which were the subject of television documentaries in the series Grand Designs. One completed university multi-purpose building (the SMART Infrastructure Facility) and an advanced research facility, the Sustainable Buildings Research Centre (SBRC) are examined. The methodology used for these two projects is semi-structured interviewing of key participants and stakeholders. The 18 residential buildings were studied by reviewing the television series episodes against a number of sustainability and construction criteria.
The results show that an additional contingency of 40% of the estimated cost should be considered for residential buildings to enable the project to be successfully constructed. Using professional groups for building design and construction is another key factor to achieve the aim.
The outcome confirms that the SBRC is more innovative and challenging than the than SMART Infrastructure Facility because it achieves the highest sustainability features such as net zero energy and net zero water. On the other hand, achieving net zero energy and net zero water need requires certain specialist equipment which makes the SBRC significantly more expensive than the SMART Infrastructure Facility per square metre.
Finally, the results from the interviews show that environmental rating systems are useful tools to construct reasonably sustainable buildings. The interviewees believe, however that for their next project, their concern would be to go beyond strict criteria of the environmental r...
