“…Along the same lines, Finland applies open-element systems based on agreed principles [14]. Similarly, the Singapore government has introduced the Minimum Buildable Design Score (B-score) and the Minimum Constructability Score (C-score) as part of a DfMA-relevant legislative framework [8]. Sherfudeen et al [14] further confirm the importance of such an approach in the context of India, stressing that the standardization of precast concrete elements and their certification in appropriate testing facilities is the only way for OSC to obtain professionals' acceptance and eventually have the same level of trust as steel products.…”

“…It also allows for the development of reliable early cost predictions [20,21], facilitates construction and helps avoid unnecessary complexity and errors [22,23]. The use of OSC and of related design principles have been extensively discussed in relation to a variety of well-known sustainability-promoting practices such as value management, buildability, waste minimization and lean construction [6,8,24,25]. The biggest advantages of OSC compared with traditional construction are thought to be the decreased construction time on site, increased quality and elimination of defects [26].…”

“…OSC has demonstrated significant advantages, from time and cost savings through to a reduced reliance of on-site skilled labour, improved safety performance and higher quality end-products [7]. Countries long enjoying OSC sustainability benefits such as improved quality, lower inventory costs, shorter lead times and less materials waste include the UK, Singapore, New Zealand, Australia and Malaysia [8]. Considering the global implications of India's economic output and environmental footprint as one of the fastest growing large economies, there is an immense necessity for India to explore the true potential of construction in light of OSC sustainability gains.…”

The tremendous urbanization pace of India calls for higher efficiency in housing development, currently typified by low productivity and poor sustainability performance. Although off-site construction (OSC) is a method of widely acknowledged efficiency, its current uptake in India is very low, and the factors hindering its wider adaptation have not been comprehensively researched. This paper employs interviews with experts, a questionnaire survey and the interpretive structural modelling (ISM) technique to achieve the following objectives: first, to reveal which factors are perceived as top barriers for OSC implementation in India; second, to develop a hierarchical model presenting the causality between these factors; and third, to propose the initiatives required for barriers with high impact on other barriers to be most efficiently tackled. The survey findings show that the barriers perceived as most important from the professionals’ point of view are design inflexibility, difficulties in storage and transportation, supply chain weaknesses, initial capital requirements and lack of skills. The ISM reveals, though, that the underlying causes for these barriers lie with factors such as public procurement regulations and the fragmentation of the sector. Therefore, the latter are the barriers that need to be targeted in priority, as per the suggested strategies.

PurposeThis paper investigates how the “Design for Sustainability” mindset of the manufacturing sector can be effectively transferred in the context of construction and proposes appropriate implementation tools for the promotion of sustainability in infrastructure projects' planning and design.Design/methodology/approachThe Design for Excellence (DfX) approach is first investigated in the context of manufacturing through the review of related literature, and the goals of Design for Sustainability (DfS), in particular, are specified. The suggestions of the literature are used as a basis for the development of the conceptually equivalent goals in the context of infrastructure projects and to highlight the construction management strategies which qualify as potential DfS tools.FindingsThis paper presents how well-known construction planning and management methods, techniques or strategies such as cost–benefit analysis, sustainability-driven procurement, contractors' involvement in design, value-based design, building information modeling (BIM) and buildability review enable the holistic promotion of the triple bottom line in feasibility, design and procurement of infrastructure projects, when combined in the context of an integrated planning approach.Originality/valueThe DfX mindset has very limited presence in the construction literature. This paper attempts to conceptualize its scope in the context of infrastructure projects while putting the multidimensional concept of sustainability as primary planning and design consideration. The proposed planning approach and the systematic mapping of the respective implementation tools can facilitate the decision-makers to achieve the desired sustainability benefits, in line with their priorities.

“…In fact, the reasons for delay for a significant number of the projects were personally witnessed by the author, who has 22 years of professional experience at Egnatia Odos S.A. (EOSA), the client organization responsible for the design, procurement and supervision of the construction of Egnatia Odos Highway and other major and minor road projects in Northern Greece and some of the Greek Islands. Furthermore, EOSA has been a source of data for construction management research in research domains such as actual duration prediction [27], value for money bridge design [39] and construction material consumption and actual cost prediction [40]. Hence, this data collection approach, which is alternative to interviewing or circulating a relevant questionnaire, belongs to a group of methods known as unobtrusive measures [38].…”

Significant universal research regarding causes of delay in road projects has been carried out based on expert opinion. This study classifies and standardizes all road construction delay factors found in the literature by developing a common risk breakdown structure (RBS) to allow for comparison between real project delay factors, and the study also proposes two delay risk assessment models (DRAMs) based on delay information from 120 real projects constructed in a similar environment with akin procurement and contract policies. The first calculates the risk priority number (RPN) and the second applies the Technique for Order Preference by Similarity to Ideal Situation (TOPSIS) multi-criteria decision-making method (MCDM). The results showed that four specific delay factors dominate in Greek road construction for which relevant mitigation proposals are made. The proposed DRAMs, while calibrated for application in Greece, can be adapted to any construction environment for which real project data is available to provide a tool for transferring experience from past projects to future projects and from accomplished to novice public client decision makers.
