Critical Literature

PurposeThe purpose of this paper is to select a suitable procurement method for steel building construction in Sri Lanka following a systematic method which weigh, both procurement selection factors and existing procurement systems.Design/methodology/approachAn abductive research stance is followed in this empirical study. Procurement selection factors were selected through a critical literature review which was followed by a quantitative questionnaire survey. The collected data were analysed using descriptive statistical analysis and relative important index.FindingsThe critical literature review outlined 46 procurement selection factors, out of which 26 factors were very important in steel building procurement selection. Short construction period and higher constructability of design are ranked at the top with the highest priority rating factors. Management-oriented procurement system was selected as the most appropriate procurement system for steel building constructions within the Sri Lankan context.Research limitations/implicationsThe study is limited to widely use three procurement systems in Sri Lankan construction industry. Yet, the process followed in selecting the most appropriate procurement system could be applied for other contexts. The implications of the study are mainly identifying management-oriented procurement as the most suitable procurement method for steel building construction in Sri Lanka.Practical implicationsThe systematic procedure of procurement method selection for steel building construction may use in the Sri Lankan construction industry to limit the resource loss due to wrong selection of procurement.Originality/valueA study which critically and comprehensively presenting a procurement selection process for steel building construction is not recorded in Sri Lanka prior to this study.

Essential Input

The construction industry, which is a labour intensive and skill development of the industry would yield both economic and social returns to the national economy. Among other occupational categories, there is a significant demand for the plant and equipment (P&E) operators in the construction industry. Nevertheless, limited numbers of research are available on the said area. Hence, the aim of this paper is to investigate the status of P&E operators in Sri Lankan building construction projects. Accordingly, this study encompassed a qualitative research approach, and six semi-structured expert interviews were conducted as the data collection tool. The study revealed that mainly two categories of P&E as moveable and immovable and further identified subcategories under each. Based on the results, occupational map was developed for the P&E operators in building construction projects in Sri Lanka. Furthermore, the study revealed that technical and mechanical skills as an essential input for an efficient P& E operator. Moreover, the paper discussed issues with P & E operators. Accordingly, inconsistency, taking long leave, poor health conditions, less experience, and less motivation were identified as prominent issues.

Awareness Programme

Life Cycle Costing (LCC) is a tool, which can evaluate all the building-related costs over a specified period of time, as mentioned in the agreed scope. Though there are number of benefits, LCC practices of consultants in the building industry are claimed to be weak. Hence, the aim of this research is to investigate barriers in practicing LCC techniques experienced by Sri Lankan quantity surveyors. Accordingly, a mixed approached was followed in data collection through a questionnaires survey and a series of expert interviews. However, in Sri Lanka, building construction consultants are not practicing the LCC concept to a greater extent. This research identified, lack of awareness on the LCC tool by employers and practitioners, lack of knowledge on LCC and lack of previous data as the major barriers for practicing LCC techniques in local context. It was suggested that enhancing the practice of LCC through conducting various awareness programme on LCC concept, build up and maintain the proper database and introducing user friendly tools, applications, calculations methods, guidelines and regulations, will lead to avoid above mentioned barriers, which will ultimately enhance the proper practice of LCC concept in the Sri Lankan quantity surveyors.

Building construction contributes to a substantial consumption of raw materials compared to other sectors in Sri Lanka. Despite the excessive consumption of raw materials, industry is suffering due to low productivity and economic inefficiency. Thus, the circumstance has led to employ alternative building materials to overcome productivity and cost inefficiency with favourable impacts on sustainability. Polymer has become a global phenomenon with increasing demand as sustainable alternative. Polymer facilitates multiple applications in building construction due to its supreme properties and characteristics. Thus, this research focused develop a quantitative model based on factors related to productivity enhancement and cost reduction to measure the applicability of polymer materials in Sri Lankan building construction. A mixed approach consisting of semi structured interviews followed by a questionnaire survey was adapted for conduct this study. 12 experts were selected for the semi structured interviews and 34 respondents participated for the questionnaire survey. The significance of favourable impact to the productivity and cost efficiency of using polymer materials have been identified in the study. The study discussed the applicability of polymer types in building sector in Sri Lanka and derived resulted in a quantitative model to measure applicability of polymer adoption in the terms of productivity and cost related factors. Study concluded that inherent properties of polymers, buildability, ability to prefabricate, life cycle cost, handling would improve the applicability to local context. Further, relationship identified through the regression model would assist practitioners to select polymer materials while enabling researchers to improve the quality of the products.

Purpose Delayed payments have been long standing, pressing issue in construction projects, especially in Government-funded construction projects. The root causes and the consequences of delayed payments must be identified before implementing strategies to mitigate the consequences of such delayed payments. However, these causes and consequences and the parties responsible for managing the delayed payments have not been identified so far. Therefore, the purpose of this study is to investigate the management of payment delays in Government-funded construction projects. Design/methodology/approach The study used a mixed approach comprising four case studies and a questionnaire survey. The empirical data collected from the case studies and the questionnaire survey were analysed using manual content analysis and mean rating, respectively. Findings The study identified the most significant causes and the most significant consequences of delayed payments that occur in Government-funded construction projects. It also revealed the strategies that clients, consultants, contractors and other parties can adopt to mitigate the adverse consequences of such delayed payments. Originality/value This study identified the most significant causes of delayed payments in Government-funded construction projects, the most significant consequences of such delayed payments and the most suitable strategies the clients, consultants and contractors can adopt to mitigate the consequences of such delayed payments. Thus, this study supports streamlining the management of payment delays in Government construction projects and identifies the roles that different parties must play in managing payment delays in Government building projects, which is an under-researched area.
