Lightweight foamed concrete brick is new construction materials. It gives a prospective solution to building construction industry, this research aims to study the cost, dead loads, environmental issues and energy consumption from using lightweight foam concrete bricks as construction materials by utilizing building information modeling technique. The results obtained from this modelling proved that the cost of brick work using lightweight foamed concrete units of grade A (2000 kg/m3) and B (1800 kg/m3 ) is higher by (19.4% and 11.9%) respectively than the activity cost using traditional fired clay bricks. For grade C (1600 kg/m3) that cost was very close to fired clay bricks (+2.9%). while the construction of brick work using light weight foamed concrete units of grade D (1400 kg/m3) and E (1200 kg/m3) was lower by (8% and 18.6%) than fired clay bricks. Besides that, the dead load generated by building units was decreased by (7.7-38.5%) for grade (B, C, D, E) than the load of fired clay bricks, while the load generated from used lightweight foam concrete bricks grade is very closed to fired clay bricks (+2.5%). There was a reduction in energy consumption by the rate of (4.1-62.2%) for heating and (9.8-73.4%) for cooling as wall sharing in energy consumption. Environmental analysis showed sustainable potential so that the production of lightweight foamed concrete units reduces CO2 emission by (46.5-67.9%) compared with the fired clay bricks. Finally; it can be concluded that building units produced in this research with LWFC, characterized with properties can efficiently compete the fired clay bricks.

Abstract. The archaeological site is a mine of data and information that helps to deepen the knowledge of its origin, history, and structure. This virtuous approach becomes even more effective when these data, properly processed and structured, form the basis for a project of conservation and enhancement of the cultural asset.The Roman mosaics dug in Castiglione delle Stiviere in 1995 represent an interesting case in which all the archaeological information, made available by the Superintendence, was used through an HBIM (Historical Building Information Modeling) approach for the conservation project. The Stratigraphic Units (US) of the findings have identified the strategy for the geometric and informative modeling of the BIM (Building Information Modeling) model and have also been exploited in the design phase for the project of the new roof structure and especially for the cost analysis. The structuring of the data by stratigraphic units was also used in the drafting of the preventive and planned conservation, necessary to enhance and prolong the state of good health of the property.This work has been developed in the internship activity within a training course on HBIM, in collaboration with the Diocese of Mantua, owner of the property.

Building Information Modeling (BIM) is gaining attention worldwide due to its assistances during the entire building’s construction life cycle covering all phases of project from commencement to accomplishment. BIM integrates different disciplines by effective communication, analyzes the project systems for constructability, estimates the cost and time of projects at any time using quantity takeoffs. Notwithstanding that fact Pakistan like other developing countries is lagging in Building Information Modeling (BIM) adoption. To facilitate the adoption of Building Information Modeling (BIM) in the AEC industry, the purpose of this research study is to identify the important factors for BIM adoption among construction engineers of Pakistan to carry out the awareness. It is found statistically that Building Information Modeling (BIM) capability is most important factors for the adoption of BIM among the construction engineers in Pakistan having the factors of motivation and management support which positively effect on BIM adoption in Pakistan. The trainings are very important to increase the BIM adoption in the industry.

Design Support Tool

The architecture, engineering, and construction sector requires carbon-intensive materials, such as steel, in the construction process and generates a large amount of waste in the life cycle. This causes global warming and waste problems. The demand for the reuse of construction materials is increasing, although it is not the convention, to reduce the environmental impact. Although the sustainable effect of the reuse of materials has been proven in several studies, materials are not always reused in practice, owing to the lack of an information system for reusable materials and the economic uncertainty. In this study, we propose a framework for designing structures using reusable steel beams. The design framework consists of a material bank and a design support tool. The material bank provides information on reusable materials based on the building information modeling. The design support tool generates efficient material procurement plans and provides information about the environmental and economic impact of the project. In a case study used to verify the framework, CO2 emissions were reduced by up to 77% through material reuse, which was consistent with the results of previous studies. However, owing to the cost of processing reusable materials, the overall cost was found to increase by up to about 40%. Therefore, an economic analysis over the entire life cycle when using reusable materials needs to be done.

The housing sector of Malaysia plays a very prominent role in meeting the major requirements of accommodation throughout the country. However, this sector consumes a handsome amount of resources among which the construction materials are a prime resource. Besides the valuable contribution of housing sector, the building materials used make a significant contribution in embodied CO2 emissions. In order to access the magnitude of CO2 from housing sector, it is necessary that effect of embodied CO2 emissions from the materials used in conventional housing construction in Malaysia shall also be studied. This study focuses on the embodied CO2 emission from the materials used in construction of a typical low cost house which are commonly adopted in Malaysia. The virtual model of selected single storey low cost house was developed using Building Information Modeling (BIM) concept. The results highlighted that bricks (37%), concrete (22%), mild steel (19%), steel rebar (7%) and roof tiles (6%) are the top five materials responsible for CO2 emissions. The overall contribution of single storey house in terms of embodied CO2 emissions is observed to be 34 kg-CO2 / sq. ft. This study has helped to highlight the potential contribution of conventional materials used in typical housing sector of Malaysia.

Building information modeling (BIM) adoption is an emerging trend in Malaysian construction industry. BIM is expected to bring better project performance and address the various construction dilemmas stemmed from construction disputes. Construction disputes has been associated with high transaction costs, which subsequently increase overall project costs. Hence, BIM has been adopted in project procurement to address construction disputes for better project performance. Studying the transaction costs in BIM adoption procurement is deemed beneficial particularly when the ambiguity of a project performance is high. This is especially true when the number of projects adopting BIM is still comparatively small to ascertain the benefits of BIM. Transaction cost economics (TCE) is a theory and methodology for relatively evaluating the cost-effectiveness of institutional arrangements in managing transaction, and therefore, studying TCE in BIM adoption procurement can be beneficial. Such an effort can improve the understanding of the benefits of the transactions made. Previous research has managed to conclude that the traditional procurement resulted in higher transaction costs compared to the design-and-build procurement. Hence, this study attempts to identify the transaction costs in BIM adoption procurement. A systematic literature review was performed to investigate the TCE in procurement to profile the transaction costs and its components in BIM adoption procurement. The outcome of the systematic structured literature is a conceptual framework combining the “RIBA Plan of Work with BIM Overlay” developed by RICS with a refined transaction cost components categorisation. The framework is further classified into pre-contract and post-contract transaction cost components specifying the fixed and variable components, and either visible or hidden. It is believed that the unbundling of the components of transaction cost in BIM adoption procurement could provide a solid foundation in developing a guideline for industry players to better understand, apply, and manage BIM adoption procurement
