The construction sector is notorious for the dichotomy between its intensive use of information in its decision‐making processes and its limited access to, and insufficient use of, the pertinent information that is potentially available, e.g. on the internet. This paper seeks to examine this issue. To solve this problem (the ‘problem of information aboutinformation’), a multidisciplinary team developed an online question‐answering (Q.‐A.)system that uses natural language for the query and the reply. The system provides a direct answer to questions posed by building industry participants, instead of providing a list of references (as is the case with most online information retrieval systems), much as if onewere asking a question of, and receiving a response from, an expert.It has the capabilitiesto process questions in natural language, to find appropriate fragments of answers indifferent web sites and to condense them into a paragraph, also written in natural language. The main features of the system are that it uses domain‐specific knowledge (in the form ofa hierarchical specialized thesaurus complemented by terms of fieldwork parlance),semantic categorization, a database of filtered and indexed web sites, and an online interface that is adapted to different profiles of actors in the construction sector. The testing process shows that the system goes beyond the lists of references and links provided by traditional search engines on the web.The Q.‐A.system already gives 70% of satisfactory answers. The Q.‐A.system can be applied to other business domains apart from information retrieval and decision‐making in the building sector. It is also possible to apply it to the exploitation of in‐house knowledge management database.

The building industry, through its structure and its mandate, faces endemic information problems; expert systems are expected to impact positively. Expert systems are suited to situations of uncertainty; knowledge and reasoning are separated, allowing easier updating. Knowledge acquisition from human experts is difficult and problems of information reliability arise, suggesting the scope for cooperation between knowledge engineers and documentalists familiar with the domain. In building, prevailing conditions seem to indicate the appropriateness of expert systems, particularly during the design phase; however, written documentation and general research results are rarely consulted. This highlights the need for an information ‘refining’ stage between production and use. It is easier to set up expert systems for specialised sub‐domains; however, on‐going research is attempting to develop a comprehensive approach to project‐specific information that would be operational from initial design through to completed construction. Criteria for a comprehensive design information system can be listed.

The purpose of this paper is to address an aspect of the innovation process leading to manufactured construction, which is often ignored, namely the organizational changes that necessarily accompany major innovations such as manufactured construction, calling for systemic organizational design.

The information for the case histories was obtained over a number of years by embedded research, where the researcher played an essential role in the projects described, thus allowing access to unpublished information. This observation‐based information was compared to other cases reported in the literature or about which knowledge was obtained though other means, enabling analytical generalizations to be drawn.

Results confirm the initial expectations. In a context of minimum state intervention, e.g. through mechanisms of market aggregation (in UK and the USA for example), namely where the internal forces of the building sector act upon each participant (including manufactured construction innovators), the design of an appropriate organization with its accompanying novel relationships is essential.

This paper makes it possible to show that contemporary manufactured construction innovators should recognize the importance of up front organizational design as a co‐requisite for technical design. This phase is often overlooked, exposing the innovator to unnecessary risks.

Within the framework of a research project into alternative ways of representing documentation languages and into their flexibility, an attempt is made to draw up a list of performance criteria that an ‘ideal’ thesaurus graphic display should respect. However, a study of the main bibliographies listing thesauri, shows that less than 6 per cent of them contain graphic displays, even though a concurrent literature survey reveals that such displays offer many potential advantages. Up to now, use of displays was probably limited by technology and by the rarity of studies into the cognitive processes of the users of automated systems. Current research in several disciplines (computer graphics, ergonomic psychology and spatial representation) should contribute to the emergence of new types of documentation retrieval tools, well adapted to a broader and more diversified clientele.

The purpose of this research is to explore and test conceptual issues of how communities of practice (CoPs) are a recognized means of transferring knowledge. Analysis of data, derived from reflection upon experience gained by close full‐time engagement on three complex, large‐scale engineering construction projects. Five emerging themes that help to explain how CoPs may be nurtured to increase the effectiveness of project management are revealed: creating a knowledge environment, discovering and recruiting potential members, information sharing, time for communicating, and motivation and rewards. The development of CoPs requires time and the creation of a knowledge environment. In the complex world of international construction, most projects are unique physical undertakings, have teams that have never worked together before, have a limited duration, with participants located in numerous countries. Thus, there is a natural tension between the need and the reality that requires strong cross‐cultural leadership, and special techniques, if CoPs are to be utilized. This paper practically illustrates, based on rigorous organizational literature theory largely missing from the engineering community, how CoPs can be actually nurtured and used. The metaphor used to illustrate this should resonate strongly with construction engineers and designers.

Earthquakes strike without warning, even though they are known to recur. It is nonetheless difficult to mobilize resources to plan for them in advance, despite the high social and economic costs that can be anticipated, and despite the humanitarian obligation to provide quality and safe housing.

This research examines two post-earthquake housing reconstruction projects in rural areas of Turkey, where different procurement strategies were used. A top-down strategy was adopted in Dinar after the October 1995 earthquake; and a bottom-up strategy, was adopted in the Orta district in Cankiri after the June 2000 earthquake in the region.

Based on information obtained from government agencies, building contractors and the projects beneficiaries, a comparison has been made between the two procurement methods. While no generalized conclusions can be drawn – as the projects were conducted in the particular circumstances that prevail in rural areas of Turkey – it is possible to highlight key factors that can properly influence future housing procurement processes.

This paper aims to present an overview of innovation in the construction sector, its forms, its inherent pitfalls and difficulties, and some underlying reasons for them. The familiar distinction between technical and organisational innovation is inapplicable in the fragmented construction industry.

This paper is based on systematic observation, accompanying many years' hands-on experience.

The processes of innovation in construction require that the innovator (possibly starting from a narrow idea or opportunity) broaden his/her view to take into account the impacts of the intended innovation on the priorities of other stakeholders, in an iterative process. In other words, orchestrated organisational changes must accompany – if not precede – technical innovation.

This paper specifically describes the processes and constraints of innovation in the context of the construction sector.

Failure to take into account the dual obligation to innovate simultaneously on the organisational and technical fronts will lead to yet one more failed attempt. Such a failure represents a waste of time and effort, and a missed opportunity to contribute to improved construction.

This paper is based on a uniquely broad experience-based view of innovation, covering a period of more than five decades; this feedback from experience can help innovators directly and provide evidence for subsequent research.

The aim of this chapter is to compare the content of two essays: Oskar Lange's 1931 ‘Crisis of Socialism’ and Tadeusz Kowalik's 1996 ‘August – the Bourgeois Revolution of the Epigones’ in order to try to determine the extent to which Lange's paper influenced Kowalik's ideas. We find that Lange's article was possibly Kowalik's only source of theoretical knowledge about bourgeois revolutions and their course when he wrote his 1996 piece. What probably struck Kowalik most in ‘Crisis of Socialism’ in the context of Polish transformations was the similarity (real or apparent) between the situation in Poland in 1905–1918 and that in 1980–1989 (or even 1980–1992), that is, the possibility of constructing a ‘bourgeois class state’ only through a workers revolution immediately preceding such a construction. On the basis of this analogy, in ‘August…’ Kowalik, as we argue, introduced a novelty into his reflections: he fortified his earlier, more lax analyses with the concept of ‘bourgeois revolution.’
