Abstract

Purpose

Governments of many developing countries that are unable to develop their infrastructure in order to obtain financial resources prefer to establish public–private partnerships (PPPs) for providing the much-required infrastructure. Time is thus opportune for Sri Lanka, which is also a developing country, to make use of PPPs to develop its road network. The purpose of this paper is, therefore, to identify the PPP models that suit road construction in Sri Lanka.

Design/methodology/approach

The study used a mixed approach. The characteristics of road construction, procurement selection factors to be considered in road construction, and the different PPP models that can be used for such procurements were identified through a comprehensive literature synthesis. The findings were validated using expert interviews. A questionnaire survey identified the PPP models that suit road construction in Sri Lanka. The most suitable model among them was identified by ranking the PPP models using procurement selection factors.

Findings

Build–Own–Operate–Transfer was identified as the PPP model that best suits road construction in Sri Lanka. However, investors may not find it attractive because of its high payback period, a result of the low traffic volume in Sri Lanka. Therefore, a PPP model that involves road construction alone will not be feasible in Sri Lanka. It will have to include the construction of other infrastructure as well.

Originality/value

The study identifies a PPP model that best suits the road construction projects in Sri Lanka.

Abstract

Purpose

The 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/approach

An 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.

Findings

The 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/implications

The 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 implications

The 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/value

A study which critically and comprehensively presenting a procurement selection process for steel building construction is not recorded in Sri Lanka prior to this study.

Abstract

Purpose

The construction industry is one of the most stressful industries. Thus, quantity surveyors (QSs) who work at sites frequently experience high levels of occupational stress. The gender of a QS also has a significant impact on his/her occupational stress. Hence, this study aims to investigate the management of occupational stress in QSs working at sites for contractors (hereinafter referred to as CQSs).

Design/methodology/approach

The study adopted a mixed approach using semi-structured interviews and a questionnaire survey for female and male CQSs to identify, validate and rank the stressors and symptoms of occupational stress in CQSs and the strategies of managing that stress based on their significance levels. Manual content analysis and the mean weighted rating were used to analyse the data collected.

Findings

Heavy workload was the most significant occupational stressor of CQSs, whereas sleeping disorders were their primary symptom of occupational stress. Establishing a proper work programme was identified as the most effective stress management strategy for male and female CQSs. This study shows that many site QSs are stressed owing to their heavy workloads and work obligations and that their stress-related attributes significantly depend on their genders.

Originality/value

This study is significant because no previous studies have been conducted on managing occupational stress in CQSs in male and female CQSs. The study findings can be used to identify the stressors and symptoms of occupational stress in CQSs early and use appropriate management strategies to enhance the work satisfaction and productivity of CQSs suffering from occupational stress.

Abstract

Purpose

This paper investigates the effectiveness of metacognitive teaching methods on students' reading comprehension through a lesson study case conducted in Shanghai.

Design/methodology/approach

This study adopts an experimental design with control groups and experimental groups. Plan–do–check–act (PDCA) cycles of lesson study were conducted to evaluate the effectiveness of modeling, self-questioning, think aloud and KWL strategy in Chinese language lessons. Metacognitive teaching strategies were implemented at a junior high school in Shanghai. The data was collected via lesson observation, interviews and pre- and posttests.

Findings

Results identified a significant difference between the incremental scores of students' reading comprehension in the experimental group and control group. The findings from the lesson observation showed that metacognitive teaching strategies in Chinese language developed students' reading comprehension. Moreover, PDCA cycles of lesson study helped the teachers improve metacognitive teaching strategies.

Originality/value

Few studies have been conducted to validate metacognitive teaching through lesson study in the context of China schools, and this study contributes to a new research dimension of lesson study on developing pedagogical practices to improve student learning outcomes.

Abstract

Purpose

The use of public–private partnership (PPP) approaches for developing infrastructure has been well recognized. The allocation of risk between public authority and private sector differs among the different types of PPP projects. The objective of the paper is to analyze the factors that influence the type of PPP and the performance of different types of PPP contracts.

Design/methodology/approach

A unique data set of 202 national highway PPP projects from India, comprising 154 toll and 48 annuity projects formed the basis of the study.

Findings

There are significant differences between toll and annuity PPP projects. The former are longer, are implemented in better developed states but are also characterized by higher cost over-runs. The latter are characterized by higher debt–equity ratio.

Practical implications

Mitigating revenue risk can significantly enhance the debt capacity of the projects, thereby reducing the overall cost of capital. To make toll roads attractive for bidders, they have to be developed as longer stretches. Toll projects that are immediately ready for development at the time of award would reduce cost overruns of toll projects and sustain the interest of private developers.

Originality/value

Comparison of toll and annuity PPP road projects has never been done previously. The unique data set used in this study highlights the differences in characterization and performance for both the project types. The study provides evidence support to “intuition” and enables policymakers to choose the right form of PPP to realize their objectives.
