When attempting to achieve sustainability goals for integrated facilities, many green rating systems are available to guide the design, construction, operations and maintenance of a project. Due to the large number of sustainability tools that are available or mandated, it can be confusing to determine which set of guidelines to follow. For the Washington State Ferries (WSF), there is no green rating system which correlates perfectly with the unique intermodal challenges presented by ferry terminals. This paper focuses on five rating systems applicable to WSF: GreenLITES, LEED, Sustainable Sites Initiative, The Port Authority of NY/NJ Sustainable Infrastructure Guidelines (draft), and the draft Marine Vessel Environmental Performance Assessment (MVeP). These rating systems are integrated with a developing set of sustainable ferry guidelines in a green rating integration platform (GRIP). The GRIP readily relates credits and guidelines across multiple systems, aiding WSF in making decisions in accordance with sustainability goals. The GRIP format might similarly be applied to other integrated projects to more effectively and economically address sustainability across all aspects of projects and facility operations.

The main objective of this paper is to identify the design criteria for a BIM Education Resilient System STEM program. The curriculum's development will semantically relate to resilience concepts with Systems Engineering and Building Information Modeling (BIM) practices and standards. The Sustainable Facilities and Infrastructure in Constrained Environments' (SuFICE) in advancing STEM to Support Facility Design, Construction, Operations and Maintenance collaborative project is to be led by The National Institute of Building Sciences, and Total Learning Research Institute. The participating organizations intend to: engage representatives from across the building and infrastructure industry to revise existing STEM curricula and materials and develop new curricula and materials that recognize the role of science technologies important to both education and the building industry.

Decision Making Tool

There are multitudes of sustainability rating systems and guidelines, and it is difficult to decide which ones to use and how to use them. In addition, multi-modal projects have different focal areas and associated rating systems related to each mode or other aspect of the project. Five green ratings systems representative of aspects of a multi-modal ferry facility had previously been selected and were used in a four step methodology to synthesize into a strategic decision making platform. This current research focuses on how to make more detailed decision making harmonization amongst the credits in the rating systems. Using an analytical hierarchy process (AHP) of the credits in the rating systems, it was determined that the two main groups of information that could be used for harmonization were key intents or goals (KI) and key strategies or practices (KS). A short cursory case study example of how these KIs and KSs might be further cross-coded in an open database with the credit subcategories and corresponding rating systems is also presented. The database can filter the credit subcategories across the rating system for a specific key intent or key strategy. The harmonized lists and database may facilitate decision makers and construction managers in correlating intents and methodologies for a project across multiple rating systems.

Big data applications consist of i) data collection using big data sources, ii) storing and processing the data, and iii) analysing data to gain insights for creating organisational benefit. The influx of digital technologies and digitization in the construction process includes big data as one newly emerging digital technology adopted in the construction industry. Big data application is in a nascent stage in construction, and there is a need to understand the tangible benefit(s) that big data can offer the construction industry. This study explores the benefits of big data in the construction industry. Using a qualitative case study design, construction professionals in an Australian Construction firm were interviewed. The research highlights that the benefits of big data include reduction of litigation amongst projects stakeholders, enablement of near to real-time communication, and facilitation of effective subcontractor selection. By implication, on a broader scale, these benefits can improve contract management, procurement, and management of construction projects. This study contributes to an ongoing discourse on big data application, and more generally, digitization in the construction industry.

Impact Reduction

Construction accounts for a considerable number of environmental impacts, especially in countries with rapid urbanization. A predictive environmental assessment method enables a comparison of alternatives in construction operations to mitigate these environmental impacts. Process-based life cycle assessment (pLCA), which is the most widely applied environmental assessment method, requires lots of detailed process information to evaluate. However, a construction project usually operates in uncertain and dynamic project environments, and capturing such process information represents a critical challenge for pLCA. Discrete event simulation (DES) provides an opportunity to include uncertainty and capture the dynamic environments of construction operations. This study proposes a predictive assessment method that integrates DES and pLCA (DES-pLCA) to evaluate the environmental impact of on-site construction operations and supply chains. The DES feeds pLCA with process information that considers the uncertain and dynamic environments of construction, while pLCA guides the comprehensive procedure of environmental assessment. A DES-pLCA prototype was developed and implemented in a case study of an 18-storey building in Northeast China. The results showed that the biggest impact variations on the global warming potential (GWP), acidification potential (AP), eutrophication (EP), photochemical ozone creation potential (POCP), abiotic depletion potential (ADP), and human toxicity potential (HTP) were 5.1%, 4.1%, 4.1%, 4.7%, 0.3%, and 5.9%, respectively, due to uncertain and dynamic factors. Based on the proposed method, an average impact reduction can be achieved for these six indictors of 2.5%, 21.7%, 8.2%, 4.8%, 32.5%, and 0.9%, respectively. The method also revealed that the material wastage rate of formwork installation was the most crucial managing factor that influences global warming performance. The method can support contractors in the development and management of environmentally friendly construction operations that consider the effects of uncertainty and dynamics.

Variations in the arterial, venous, and ureteral patterning of the right (r) and left (l) kidneys are common; however, concomitant involvement with all three systems is rare. Specimens that demonstrate anatomic variation across multiple systems provide an opportunity to illustrate links between anatomic concepts, embryologic development, clinical practice, and education. During anatomic study of the abdominal cavity, a total of five major arteries (3l and 2r) emerged from the aortic and common iliac axes in a cadaveric donor. Through continued study, multiple contributing veins, of different caliber, coalesced into four major renal veins (2l and 2r) that returned blood from the kidneys to the inferior vena cava (IVC) at different locations. In addition, unilateral duplication of the kidney with concomitant ureters was evident on the right side. Both ureters continued inferiorly and independently entered the bladder, each with an observable orifice adjacent to the bladder trigone. Most evident in the specimen was the anteriorly directed hilum for both kidneys. Reported measures for each of the observed anatomic variations suggest that the current specimen has an estimated incidence of less than 0.3%. This comparatively rare specimen provides an example of important anatomic concepts that are relevant to educational and clinical practices.
