Building materials occupy a large proportion of construction costs, comprising of nearly 50%, although the exact percentage varies from project to project. Given how important building materials are, due attention must be given to the strategies for procuring them. This study investigates building material purchasing practices and examines significant factors that could impact the optimum building materials for a specific project selection. This paper is an outcome of a PhD study conducted to improve supply chain practices relating to building materials for residential buildings in New Zealand in such a way that delivers the highest possible value to all stakeholders. The broader PhD study employed both qualitative (subject matter expert interviews) and quantitative (questionnaire survey) methods to gather information from those who supply and manufacture building materials, architects, builders, and homeowners. It found that the facilitation of effective materials management processes is reliant on the collaborative efforts of the entire supply chain in any construction project. When determining “best buy” decisions for key material inputs, the roles of the contractor, clients, and suppliers cannot be disconnected. Decisions relating to building materials were categorized into demand-side or supply-side choices, and a framework was developed to support supply chain stakeholder decisions in selecting appropriate materials for residential construction projects.

More than 95% of multi-story residential buildings in Austria are currently predominantly constructed with conventional mineral construction materials. This fact combined with the increasing demands for a healthy residential living atmosphere demonstrates the great potential for using ecological materials. Life cycle assessments provide information on the ecological performance of buildings, but the corresponding economical aspects are not considered. Nevertheless, the economic aspects of a certain draft are important to clients and designers. Therefore, simplified assessment-tools are needed that take into account the ecological impact as well as the building costs. This paper presents the results of an investigation supplemented by a case study of a multistory residential building, which was finished 2016 in Austria, illustrating the differences between the state-of-the-art material selection and ecologically optimized alternatives. The ecological impacts and the costs for the selected building-system were determined based on the case study. Subsequently, ecological optimization potentials were identified according to the environmental indicator OI3. Finally, the effects on component and construction costs were evaluated. The steps of this simplified process reveal the interdependency between ecological aspects and the costs of materials. This procedure represents a decision-making tool that can be used by clients as well as designers. The results of this research emphasize the large environmental impact improvements with little expenses when implementing sustainability in multi-story residential buildings as a crucial part of a green design.

The purpose of this paper is to develop an approach to analyse and evaluate continuity in Service Supply Chain (SSC), through a case study. This approach is based on the data-driven quality strategy "Define, Measure, Analyze, Improve, Control" (DMAIC) which is used to drive Six Sigma projects, and on the characteristics of Smart Supply Chain. It combines Business process management (BPM), Supply Chain Operations Reference (SCOR), and the Root cause analysis tree diagram. The chosen case study is the electricity SCC, especially the business process 'management of electricity for residential buildings' of the Moroccan electricity SSC. The paper shows that the suggested approach identifies the discontinuity causes for the studied SSC, improves the business process behavior and manages its control by providing a dashboard that encompasses KPIs for periodically controlling of the SSC "to-be" state.

Main Barrier

Construction materials usually constitute a major portion of the total cost in a building construction project. Despite the potential benefit of ICT, convincing construction organisations to embrace its use and implementation has proved a difficult task. This research seeks to identify the implementation of ICT in construction materials management processes and to investigate on the acceptance of contractors for ICT transformation to the materials management in construction projects. In relation to that, current constraints that are found hindering the acceptance of ICT in materials management processes are also identified. A triangulation research approach which consists of standard derived questionnaires, semi structured interviews with class A contractors and review of previous research were conducted. The findings from this research reveal that the implementation of ICT in the materials management for construction projects in Malaysia is at early stage. Microsoft Excel Spreadsheet and handheld devices are found to be the common ICT tools adopted in the materials management processes. Meanwhile, there is only an average level of acceptance towards the transformation of ICT implementation in the construction materials management. The main barrier is found to be the cost involvement at the initial stage or overall implementation of ICT in the materials management processes. Finally, it can be concluded that there is a lack of awareness towards the ICT implementation of materials management in the construction projects.

The Relationship

The green building certification system of Taiwan, EEWH (Ecology, Energy Saving, Waste Reduction and Health), has been in operation for more than 20 years (since 1999). In order to understand the relationship between green building certification and the construction costs of residential buildings, this study obtained 37 green building-certified residential cases and 36 general residential cases available from public information and conducted a comparative analysis. The results of this study showed that the average construction cost of a green building certification residential building was only 1.58% higher than a general residential building, indicating that green building certification does not require a large increase in costs. However, for residential buildings, achieving a high-grade (gold-grade or diamond-grade) green building certification means an increase of 6.7% to 9.3% in construction costs. This shows that the pursuit of higher levels of green building certification does require higher construction costs. In addition, the results of this study can not only provide important references for the government in making green building policies, but also offer a practical strategy for developers for decision-making.

Ventilation Rates

Nowadays, people spend an average of 87% of their time inside buildings, and about 69% at home. Hence, it is essential to ensure the highest possible level of indoor air quality (IAQ). Providing that the quality of the outdoor air is acceptable, the IAQ level is improved by increasing the ventilation rates. However, this means that a larger volume of air must be cooled down or warmed up to ensure the same level of thermal comfort. The aim of this study was to conduct a cost–benefit analysis of the IAQ in residential buildings. A case-study building was defined, and three sets of materials with different pollution emission levels were chosen: High, low, and very low. For each option, the ventilation rates required to have the same IAQ level were calculated, and the consequent energy consumption and costs were estimated by means of dynamic thermal simulation. The results show the range of the initial capital cost that could be compensated for by lower running costs, and the effect of each energy and economic input assumption on the appraisal of the affordable capital cost. In the discussion, insights into the IAQ co-benefits are also given.

Cross Case Analysis

Carbon estimating plays a vital role in the construction industry. The current focus on introducing zero-carbon construction projects reduces operational carbon, at the expense of Embodied Carbon (EC). However, it is important to reduce overall net carbon emissions. There are various methods to estimate carbon, but the accuracy of these estimates is questionable. This paper reviews a novel methodology, the Supply Chain based Embodied carbon Estimating Method (SCEEM), which was introduced recently to accurately estimate EC in construction supply chains. SCEEM is compared against existing EC estimating methods (Blackbook and eToolLCD) using a case study approach. It is also supplemented with a comprehensive literature review of existing EC methods. The EC values calculated using Blackbook and eToolLCD were mostly higher than SCEEM. Since SCEEM uses actual site data and considers first principles-based value addition method to estimate EC, it is considered accurate. The cross-case analysis revealed that SCEEM provided consistent results. Hence, SCEEM is recommended to accurately estimate EC of any type of project.

Optimal Construction

In a real cable-strut tensile structure, construction errors are inevitable. To explore the optimal construction scheme and control construction errors, this study optimized the construction scheme of a cable-strut tensile structure. First, a mathematical model of the element length error was investigated based on stochastic theory. By combining the balance equation, geometric equation and physical equation, the fundamental relationship between the pre-stress deviation and element length error was derived. Because the pre-stress in the active cable can be controlled exactly and the cable’s pre-stress deviations were zero during construction, the relationship between the pre-stress deviation of a passive cable and the element length error was obtained. Then, the statistical characteristics of the pre-stress deviation were obtained under different construction schemes using statistical theory. Finally, an example was analysed as a case study. The study showed that different elements have different error sensitivities and that different construction schemes have different error effects. Using the method proposed in this paper, the error effect of different construction schemes can be analysed, and the optimal construction scheme, with lower error effects and lower construction costs, can be selected for actual construction projects.
