Timber structures in construction have become more popular in recent years. Nevertheless, besides the complexity of designing, contracting and building these structures, a barrier to their market growth is the complexity of their supply chain relationships encompassing architects, engineers, builders and suppliers. The objective of this study is therefore to identify and characterize the supply chain relationships shared by these stakeholders within a massive timber construction project. Twenty-seven semi-structured interviews with architects, structural engineers, builders and timber element suppliers from nine countries, participant observations and secondary data were used to study the various relationship levels involved in timber construction projects. Triangulation and qualitative data analysis were also conducted. Three levels of relationships were then identified: “Contractual,” “Massive timber construction project” and “Massive timber construction industry development.” Results showed that timber structures involve value-added stakeholder relationships rather than linear relationships. These relationships appeared closer and more frequent and involved knowledge and information sharing. Furthermore, prefabricated systems allow for smoother relationships by limiting the number of stakeholders while promoting innovative thinking.

<p>Today, few new bridges are made of timber. Since the industrialization, timber bridges have increasingly lost ground to steel and later concrete bridges. In addition, timber bridges developed a reputation of high maintenance and low durability from many crossings built between the 1970s and 1990s.</p><p>Interest in timber bridges has recently grown due to new motivations in design, including an increased focus on sustainability. Efforts in research and engineering to reexamine timber bridges have led to the development of the “Integral mass-timber bridge”. The bridges will be a first: timber integral bridges without any movement joints or bearings between the superstructure and the concrete abutments.</p><p>These structures were developed taking into account the efficient use of natural resources as well as the carbon-emissions during the entire life span of the bridge: from the design and manufacturing to maintenance and operation. The body of the bridge is made of block-laminated timber beams and articulates the guiding principle of mass timber: the sequestration of carbon within the massive timber construction.</p><p>Currently, the first three of these bridges are being constructed in Germany, with completion in May 2019. The concept has been awarded with the German Timber Construction Award 2017.</p>

The purpose of this study is to assess the carbon footprint emission at UiTM Perak, Seri Iskandar Campus. The assessment focuses on electrical power and transportation usage. Questionnaires were distributed to the staffs and students to survey their transportation usage in the year 2014 while for electrical consumption, the study used total energy consumed in the year 2014. Data was calculating with the formula by Green House Gas Protocol. Total carbon footprint produced by UiTM Perak, Seri Jskandar Campus in the year 2014 is 11842.09 MTC02' The result of the study is hoped to provide strategies for the university to reduce the carbon footprint emission.
