Effective and efficient waste management plans/systems are vital in reducing and maintaining the generation of construction and demolition waste. It was proved in previous research, proper rules and regulations affect the effectiveness of the waste management strategies used in disposing of construction and demolition waste. Therefore, this research aim is to identify the regulations applicable for the disposal of construction and demolition waste in Sri Lanka to propose improvements in the available rules and regulations. Comprehensive literature and document review were conducted to approach the aim of this research. Questionnaire surveys and expert interviews were carried out to validate the findings of the literature survey and to gather required data in identifying the issues related to current rules and regulations and proposing improvements. The findings revealed that many gaps can be identified with the current regulations used in the disposal of construction and demolition waste. The results of the research identified a lack of intention in government regarding recycling, avoiding improper landfilling, and avoiding illegal dumping of construction and demolition waste as major issues. The study finally concluded the necessity of modified rules and regulations regarding the disposal of construction and demolition waste

A Study on Limitations in Material Procurement Practice for Construction in Public Sector
(2015-08-14) Edirisinghe, V; Kajendran, K
Due to the high accountability of public construction projects, several rules and regulations are being adopted in material procurement practice in public sector. These rules and regulations are practiced as per the framework provided by Procurement Guideline 2006 - Goods and Works and the Manual. Procurement Guideline 2006 is published by National Procurement Agency, Democratic Socialist Republic of Sri Lanka. This procurement guideline is applicable for any Procurement Action financed in whole or in part by Government of Sri Lanka or a Foreign Funding Agency. While these guidelines are being implemented, there are several limitations found by the practitioners. Hence this research was aimed to study the practical issues in implementing procedures stated in the Procurement Guideline 2006 - Goods and Works and the Manual. This study was done by collecting data from semi structured interviews with the industrial professionals who involve in public sector construction material procurement such as Architects, Contract Administrators, Procurement Officers, Project Managers, Quantity Surveyors, Contractors and Site Engineers. Findings of this study revealed that there are limitations existing in public sector construction procurement practice and that create cost and time overrun and quality issues.

(Ceylon Institute of Builders - Sri Lanka, 2023-07-21) Arjuna, MP; Edirisinghe, V; Manoharan, K; Herath, SS
This study investigates the physical and mental health issues experienced by neighbouring residences as a result of construction projects in Sri Lanka. Specifically, it examines the impact of these projects on respiratory distress, hearing impairments, traffic congestion, lack of landscape, and flooding conditions. Additionally, the study explores the psychological effects on residents and emphasises the importance of health and safety measures in project management. Data collection involved conducting interviews with project managers, site safety officers, and a male nurse from three selected construction sites, followed by a questionnaire survey administered to 30 neighbouring residents. The study provides recommendations to mitigate adverse impacts, raise community awareness, and promote environmentally friendly practices in the construction industry. The findings enhance understanding of the health challenges faced by neighbouring residents and offer insights to policymakers and project managers to improve the well-being of affected communities.
