Developing a Waterproofing Decision-Making Model for High-Rise Building Projects in the Tropics
(MDPI, 2023) Senarathne, Helapura Nuwanshi Yasodara; Asmone, Ashan Senel; Chew, Michael Yit Lin
The most severe problem in high-rise structures is a failure to achieve watertightness. Since the presence of water in a structure can have a detrimental impact, adequate consideration must be taken when selecting a suitable waterproofing system based on several factors. As a result, this research aims to examine the factors that affect the selection of the best waterproofing solution in high-rise building projects in the tropics. Preliminary observations were conducted to investigate typically occurring issues with high-rise buildings which contain commercial, office, and residential facilities. Data were collected through questionnaire surveys and semi-structured interviews with professionals in the waterproofing industry. This study provides a comprehensive understanding of the issues concerning waterproofing and suggests an effective solution for the same. The assessment of the best waterproofing selection criterion was analyzed by incorporating the Best Worst Method (BWM). Based on the global ranking reached, the decision-making framework was developed, and three main specifications, technical, construction, and product, were suggested to select an ideal waterproofing solution. This study provides insightful guidance for professionals in the waterproofing industry and their clientele towards an optimal solution, facilitating informed decision-making processes.

Prioritization of industry level interventions to improve implementation of design for safety regulations
(Elsevier, 2022) Asmone, Ashan Senel; Goh, Yang Miang; Lim, Michelle S.H.
Introduction: Many countries introduced mandatory Design for Safety (DfS) or Prevention through Design (PtD) requirements to reduce construction accident rates. However, there is a knowledge gap on the relative importance of industry level interventions to improve the implementation of DfS regulations. Thus, this study aims to identify and prioritize a set of industry level interventions to help regulators and industry associations understand the industry’s perceptions and improve the implementation of mandatory DfS. Method: A mixed method approach consisting of 59 semi-structured interviews, four focus group discussions, and an online poll was implemented. Results: Key challenges faced during DfS implementations were identified (lack of guidelines, lack of commitment towards DfS, the inadequate capability of DfS team, and limited effectiveness of DfS Professionals (DfSPs)). The study elicited eight industry level interventions to overcome these challenges and ranked them based on effectiveness and ease of implementation. The ranked industry level interventions in descending order are continuing training for DfSPs, samples and guidelines, DfS training for non-DfSPs, Building Information Modelling (BIM) for DfS review, strengthening DfSP as a profession, DfS awards for developers, third party audits for DfS reviews, and submission of DfS Risk Register to regulator. Conclusions: Identified interventions were classified into four intervention categories: (a) improving competency/ knowledge; (b) technological tools; (c) checks/ audits; and (d) recognitions/ certifications. The key contributions of this study are the identification and prioritization of industry level interventions for DfS, and the classification of safety interventions available to industry associations and regulators. Practical applications: Findings from this study help regulators and industry associations prioritize their resources to improve the implementation of mandatory DfS. Moreover, regulators and industry associations can also use the generic framework of industry level interventions to identify possible interventions to improve other mandatory WSH processes.
