TL;DR: In this paper, the authors investigate the delay causes in India by project sector (transport, power, buildings and water) and carry out a comparative study of delay causes and mitigation measures along with a questionnaire survey was conducted among major clients, contractors and consultants in India.
Abstract: Construction projects in India continue to suffer excessive delays. This paper aims to investigate the delay causes in India by project sector (transport, power, buildings and water) and carry out a comparative study of delay causes in design build (DB) projects with that of design bid build (DBB) projects along with mitigation measures.,A questionnaire survey was conducted among major clients, contractors and consultants in India. Importance Index was used for ranking of the delay causes. Projects were categorized based on the type, and causes of delay in each project type were identified. Projects were also categorized based on type of contract, and delay causes in DB and DBB projects were compared. Statistical analysis of responses by Cronbach’s alpha, one-way analysis of variance, Kruskal–Wallis tests was carried out with Statistical Package for Social Sciences. Semi-structured in-depth interviews were conducted with senior industry professionals to develop exhaustive mitigation measures.,The research findings indicate finance-related causes as the most critical causes of delay in Indian projects. Delay in settlement of claims, contractor’s financial difficulties, delay in payment for extra work/variations by owner, late payment from contractor to subcontractor or suppliers, variation orders/changes of scope by owner during construction and changes in design by owner were the highly ranked delay causes. The research found no significant difference in the delay causes in DB and DBB projects.,This is the first study wherein delay causes for various project types within a single country are identified. In addition, the study has identified and compared the delay causes in DB projects and DBB projects. Mitigation measures developed in this study will help professionals and project managers not just in India but other developing countries as well to alleviate delay causes and in improvement of project timelines.

TL;DR: In this article, waste glass powder (WGP) is used as an aluminosilicate source material in binary, ternary and quaternary blended geopolymer concrete.
Abstract: Incorporation of the waste glass powder (WGP) as an aluminosilicate precursor material in the geopolymer concrete preparation has been researched for the past twenty years as an alternative to the sustainable construction material because of its significant impact on the reduction of greenhouse gases. This paper reviews the various applications of the WGP in the geopolymer matrix production as binary and ternary source material and the impact of the inclusion of WGP on the fresh and hardened characteristics of geopolymer concrete. More research articles associated with the usage of WGP in geopolymer concrete were published in the last ten years. Collective information on the WGP as an aluminosilicate source material in binary, ternary and quaternary blended geopolymer concrete is not available. This review article sums up the newest findings and developments achieved in the synthesis of geopolymer concrete containing WGP as one of the aluminosilicate source material. The study concludes that WGP could be utilized as an innovative and promising eco-friendly aluminosilicate source material to manufacture geopolymer concrete, thereby providing an environmentally eco-friendly solution for the glass and Portland cement based industries.

TL;DR: The use of traditional and innovative Portland-free lime-based mortars in the conservation of cultural heritage, and the recycling and management of wastes to reduce consumption of natural resources in the production of construction materials are concerns.
Abstract: The paper represents the "state of the art" on sustainability in construction materials. In Part 1 of the paper, issues related to production, microstructures, chemical nature, engineering properties, and durability of mixtures based on binders alternative to Portland cement were presented. This second part of the paper concerns the use of traditional and innovative Portland-free lime-based mortars in the conservation of cultural heritage, and the recycling and management of wastes to reduce consumption of natural resources in the production of construction materials. The latter is one of the main concerns in terms of sustainability since nowadays more than 75% of wastes are disposed of in landfills.

TL;DR: In this paper, a system dynamics model for the construction and civil engineering industry is developed, as traditional workforce planning approaches are static and unable to accommodate the changing complex dynamics that influence workforce supply and demand.
Abstract: Workforce planning (WP) for infrastructure projects provides a readily available pool of skilled labor that can deliver a nation’s societal needs. However, achieving a robust and reliable workforce prediction is a constant challenge, as a variety of variables and factors must be considered. Despite various forecasting techniques and approaches being developed, government’s worldwide continue to produce inaccurate forecasts and consequently fail to maintain the balanced workforce required to deliver infrastructure projects. To address this problem, a system dynamics (SD) model for the construction and civil engineering industry is developed, as traditional WP modeling approaches are static and unable to accommodate the changing complex dynamics that influence workforce supply and demand. The SD model is tested and used to formulate training policies that ensure workforce equilibrium and in turn, nurture sustainable infrastructure development.
