Sealing of roof penetrations during building constructionby Scott. A. Lowe
Building Engineering, Vol.2, No.2, 2024; 132 Views, 72 PDF Downloads
For new building construction, roofs typically have a large number of penetrations that are blocked out before the roof deck is poured. After the roof is poured, these penetrations need to be sealed temporarily to prevent rainwater entering the building. Unfortunately, it is all too common that the ad-hoc approach to sealing these openings results in penetrations left open to the elements. This results in water pouring into the building every time it rains. This paper shows examples of unsealed roof penetrations and of the subsequent damage caused. The penetrations relate to the work of several different trades, who may not place any priority on this issue. It is therefore suggested that this is a problem that the construction management team has to take charge of. At the very least, the roof should be inspected before impending rain events.

Fighting for collusive bidding in the construction industry: A text mining-enabled approachby Xiaowei Wang, Keda Chen, Yuqing Zhang
Building Engineering, Vol.2, No.2, 2024; 77 Views, 30 PDF Downloads
Policy measures are crucial for regulating collusive bidding and are integral to effective governance. However, current research lacks a comparative exploration of strategies to combat collusive bidding through policy. Therefore, this study aims to identify more effective countermeasures by examining policy variations between regions with low and high incidences of collusive bidding. Using Latent Dirichlet Allocation (LDA) topic modeling, the study extracts key themes from these policies, while qualitative analysis highlights differences in approaches. It underscores that integrating electronic and information technology into bidding systems significantly reduces collusive practices. While increasing penalties can deter collusive bidding, achieving desired impacts requires thorough investigation and vigilant oversight. Additionally, strengthening external supervision enhances control over such activities. This study identifies critical governance strategies for addressing collusive bidding and advocates further research into more effective methods within the construction sector.

Evaluating the damage of collapsed bridges using remote sensing technologies: Case study: Baltimore’s Francis Scott Key Bridgeby Reedhi Shukla, Sampath Kumar Pabbisetty, Satish Jayanthi, Kamini Janardhanan
Building Engineering, Vol.2, No.2, 2024; 109 Views, 47 PDF Downloads
Bridges are vital for linking communities and facilitating economic activity. However, in the face of disaster, like ship collisions pose a significant threat to bridge infrastructure, causing structural damage and potential safety hazards. Rapid and precise assessment of the damage is essential for effective emergency response and recovery operations. Remote sensing with near-real-time satellite imagery provides the disaster scenario. This paper presents a change detection using pre- and post-disaster satellite data for Baltimore’s Francis Scott Key Bridge to identify structural damage due to the collision of the ship with support pillars on 26 March 2024. Both optical and microwave satellite data were used from open data sources and analyzed based on geospatial techniques such as change detection and surface profiling. It is estimated that an 1100-meter span of bridge was affected due to this collision, which helped to estimate the damage and mobilize the rescue operations. It may need further validation from ground truth information. Hence, the current study emphasizes the potential of remote sensing satellite data to provide near-real-time impact on disaster analysis.

Study on prediction model of nitrogen emission in the production stage of residential building materials—A case study of Guangdong provinceby Yue Lyu
Building Engineering, Vol.2, No.2, 2024; 77 Views, 44 PDF Downloads
This study aims to reduce nitrogen emissions from residential buildings and establishes a prediction model for nitrogen emissions during the production of building materials. The calculation boundary, content, and method of nitrogen emission in the production stage of residential building materials are accurately analyzed. Based on the nitrogen emission data of 20 residential buildings in Guangdong, the composition and distribution characteristics of nitrogen emission in the production stage of building materials are analyzed. The coupling relationship between building design parameters and building materials’ nitrogen emissions is established using linear regression and ridge regression. 10 kinds of nitrogen emission prediction models based on the design parameters of residential buildings in the production stage of building materials were established and verified. The results show that the linear model M3, based on the number of floors above and below ground, the area width and depth, and the ridge regression model M5, based on the number of floors above and below ground, the area width and depth, and the total number of main functional rooms, have good fitting and prediction performance, respectively. The linear regression model M6, based on the number of floors above and below ground, the area width and depth, and the total number of rooms, has the best fitting and prediction performance. M3, M5, and M6 can accurately predict the nitrogen emission composition and distribution characteristics of building materials in residential building design and lay a foundation for future research on nitrogen emission evaluation and calculation methods and nitrogen emission reduction technology strategies.

Finite elemental assessment of torsional behavior of RC beams having different shear reinforcementby Warda Jannat Juhin, Raihan Uddin Ahmed, H. M. A. Mahzuz, Md. Ariful Islam
Building Engineering, Vol.2, No.2, 2024; 61 Views, 29 PDF Downloads
In this paper, the torsional behavior of 8 beams in 4 categories with 2 different ultimate concrete compressive strengths (22.92 MPa and 43.47 MPa) was evaluated, and the best alternative of shear reinforcement pattern compared to the conventional non-welded rectangular stirrup beam (NRSB) was determined. 4 types of beams were modeled using SolidWorks, namely—Non-welded Rectangular Stirrup Beam (NRSB), Welded Rectangular Stirrup Beam (WRSB), Normal Welded Warren Truss-shaped Beam (NWWTB), and Flipped Welded Warren Truss-shaped Beam (FWWTB). The dimension and weight of reinforcement were kept the same for all beams. After simulating using ANSYS, it was seen that WRSB specimens had the largest torsional moment capacity, while NWWTB in normal orientation showed marginal improvement compared to NRSB.

Fulfilling the potentials of residential solar energy in Egyptby Atef Badr
Building Engineering, Vol.2, No.2, 2024; 31 Views, 12 PDF Downloads
Energy plays a very important role in Egypt’s economic development, but the country has a gap between its produced energy and the demand of its growing population. Utilization of solar power systems in Egypt could help the country to close this gap and fulfil its national and international obligations. However, since 1980, the focus in Egypt has been on large-scale industrial solar projects. Limited attention is given to smaller systems for typical residential buildings. The aim of this research, therefore, is to highlight the potential of small residential solar systems (SRSS) in Egypt. With the huge number of residential buildings accommodating more than 115 million Egyptians, SRSS could be the unearthed gem of a sustainable source of energy in Egypt. The geographical location of Egypt and climate were used to generate solar data using the Global Solar Atlas application. The amounts of monthly and annual solar irradiations were calculated and analysed to decide the best orientation of the system (facing east, west, north, and south), identify the optimum tilt angle of the system, and determine the size of the solar panels. A case study was used to illustrate the procedures of designing SRSS for a typical residential building in Egypt. The results showed that a 26 kWp SRSS oriented facing the east with an optimum tilt angle between 15° and 30° could produce an annual total output of electricity more than the annual demand of the occupants of the studied residential building. Such a system would fit easily on the roof of the building. It was concluded that the installation of SRSS in Egypt could help the country meet the demand of its ever-increasing population if properly regulated, financed, and managed. It is recommended that Egypt develop and implement policies to make installations of SRSS an attractive choice among homeowners and investors by introducing encouraging incentives and creating a competitive market with affordable SRSS.

Value-based analysis of the negotiation for the construction of a church domeby Mario Luis Chew Hernández, Leopoldo Viveros Rosas, Raúl Gómez Gómez-Tagle
Building Engineering, Vol.2, No.2, 2024; 108 Views, 64 PDF Downloads
In the construction industry, the signing of contracts between contractors and clients is a common practice. The entities signing these contacts have vastly different objectives in the context of the project: the contractor is motivated by the achievement of profit, while the client has objectives that can be economic, aesthetic, related to completion time, etc. According to negotiation theory, the greater the difference between the objectives of the sides, the better the contracts that can be achieved in the negotiation. Therefore, the analysis of a contractor-client negotiation in the building industry should be based on a complete understanding of the objectives of the sides. Kenney’s Value-Focused Thinking (VFT) provides a framework on which such understanding can be achieved. This paper presents a VFT-based methodology to analyze the contractor-client negotiations in the context of construction projects. The methodology is illustrated by analyzing, in retrospective, the negotiation between a construction company and a client regarding the construction of a dome for a church. The results show the usefulness of analyzing the negotiation from the point of view of the sides’ objectives.

Building materials alternative approaches: A bibliometric and review approachby Nathalie Tornay
Building Engineering, Vol.2, No.2, 2024; 188 Views, 125 PDF Downloads
In this paper, we develop a global vision of environmental impact with alternative building materials in architectural design. A bibliometric study is based on 1827 scientific research publications on alternative materials produced between 1998 and 2022. More than 90% of these documents have been published in the last ten years. This bibliometric study goal is to develop a systemic approach for the characterisation of alternative solutions in the context of scarce resource context and climate change. This study highlights three different approaches: 1) an ‘integrative’ approach that develops an implementation approach combining environmental concerns and design teams’ own working methods in the selection of materials; 2) an ‘additive’ approach that selects some environmental criteria (carbon footprint and energy consumption) in addition to implementation issues; 3) a ‘subtractive’ approach that focuses solely on implementation issues.
