More than 65 organizations representing owners, contractors, and 25 academic institutions have combined their re- sources to tackle advanced construction research. The institute then represents an important model for broader public-private partnership in construction research. The list includes a large number of projects related to improving methodology, many of which could be valuable in the international arena. The civil engineering research com- munity is also largely based in universities, but there is some me- chanical, electrical, or electronic research of direct relevance to the construction sectors being done by these other departments.
To a limited extent both architectural and civil engineering research in- stitutions do projects related to mechanical and electrical systems.
Most research institutions have projects tied to computer-based de- sign and engineering, but more work is needed, particularly to bring new results into practice, through teaching and professional outreach programs. While spending on research often exceeds U. The work supported by the Swedish government on behalf of the building industry tends to be much more people-oriented, describing user requirements and how these requirements should be accommodated in design.
However, there does not appear to be any better match between the research programs and the teaching programs in the universities than in the United States. The Soviet Union has six major research units within its con- struction agency Gosstroy. Five of these units do traditional science and engineering research of the type done in government building laboratories around the world, but one research unit concentrates on "cybernetics.
With their government's strong encouragement, the six large, integrated Japanese construction companies all support research by internal units.
These programs include hundreds of people, excellent facilities, and a broad spectrum of subjects see box. This committee has not undertaken to recommend a complete agenda for research in construction and design, and planning of such an agenda by a single centralized body would in any case be unproductive.
However, committee members feelthat certain types of research are clearly needed, such as these two examples: The general subject of "diagnostics" is talked about within the architectural research community as an area for methodological improvement. Work on this subject could be greatly enhanced if uni- versity researchers and practicing architects worked in parallel with firms that are in the business of designing and marketing diagnostic instruments.
A program that provides special funds to research units as contrasted with individuals within universities that had already obtained an agreement for matching funds from instrument compa- nies would encourage vertical integration between the architectural sector and the equipment-producing sector.
The development of safety methods for structures during the construction phase could benefit from case studies. For example, the NBS Center for Building Technology has just completed a study of the collapse of L'Ambiance Plaza in Bridgeport, Connecticut, a building which was being constructed using the lift-slab method.
This collapse could serve as a case study for a structural engineering faculty to develop a continuing education course for engineers in practice, thus providing a link among a federal laboratory, university research, and professionals. While this subject is unique and timely,. As will be discussed further in Chapter 6, the development of advanced concepts for infrastructure poses an international challenge of enormous proportions.
The present practice of dealing with urban transportation, water and energy supplies, waste management, and communications is based on inventions developecI nearly a century ago.
In the largest cities of the world these old inventions are clearly not well suited to dealing with present problems, and in the small communities of the developing world there has always been a kind of hand-me-down, makeshift quality to the nature of infrastructure investments.
There should be special programs to concen- trate on infrastructure development within the university research community. These programs should encourage university units that are skilled in the areas of the "emerging technologies" to explore ways of creating new or higher-performing systems for infrastruc- ture.
Technologies such as new ceramics, advanced microelectronics, biotechnology, and genetic engineering should be incorporated into joint programs with the architectural and civil engineering faculties, and especially to provide graduate students from these technological areas the opportunities to work on infrastructure. In such programs universities could associate with trade and professional groups, such as the American Public Works Association, to introduce engineers in practice to new technologies and their capability.
The committee recognizes that some engineering schools can best be encouraged to expend research and teaching in construction by. Programs may be needed to link employers with graduate programs in construction by having the university offer special graduate programs for mature employees of professional firms. As the Japanese mode! This pattern is unlikely to change in the fore- seeable future, nor is it clear that it ought to change.
What is clear to the committee, however, is that better mechanisms for linking research to construction practice are needed. There is a need as well to increase the speed with which ideas from one field of research are tested for their value in other fields, and with which ideas of value enter practice. The case of the Bell Laboratories Case Study 4 , drawn from an industrial situation very different from construction, is nevertheless instructive because of their great success in linking research to the market.
In construc- tion, where the market is distributed among so many suppliers and buyers, projects built with federal government funds can be used to demonstrate new technology. A good example is the introduction to U. Department of Commerce has noted, "Over the next twenty years it is totally reasonable to expect that we will see widespread application of the following technologies: Mechanisms are needed to expose these new technologies and con- struction to one another, and to produce design and construction professionals competent to make the connections required for inns vation.
Besides institutional research, there must be training and education. Department of Commerce, Washington, D. The committee recognizes that the Be]] Labs are a product of a private sector monopoly company that had vertical integration and an ability to make elective decisions about resource allocation and management strategy, with greater ease than is the case in U. Nevertheless, many characteristics of the Bed Labs can serve as a useful mode] for institutional arrangements needed to strengthen U.
The invention of the telephone was not inspired by a pre-existent popular demand. Rather, it came about largely through the ingenuity and vision of one man Alexander Graham Bell. His belief that there was a great potential need for two-way voice communication over a distance, a need of which few men had been conscious, was confirmed by its immediate success and spectacular growth in spite of early technical limitations.
By the end of the first fifty years a great new industry had been developed. There were nearly seventeen million telephones in the United States, almost twelve million of them in the Bell System.
And in perhaps no other field had the force of scientific research in support of engineering development been so effectively demonstrated. At the beginning of the telephone industry there was no art of electrical engineering nor was there any school or university conferring the degree of electrical engineer. Notwithstanding this the general engineering staR was soon organized, calling to their aid some of the most distinguished professors of science in our universities.
As problems became more formidable and increased in number and complexity, the engineering and scientific staff was increased in size and in its specialization so that we now have working at headquarters on the problems of the associated companies some engineers and scientists carefully selected with due regard to the practical as well as the scientific nature of the problems encountered.
By the technical programs of the Bell System had so grown in range and intensity, and in number of personnel, as to suggest formation of a single new organization to handle most or all of these activities.
Such an organization was formed on December 27, , and started operations on January 1, , under the name of Bell Telephone Laboratories, Incorporated. At the date of incorporation, the personnel numbered approximately 3,, of whom about 2, were members of the technical staff, made up of engineers, physicists, chemists, metallurgists and experts in various fields of technical endeavor Technological innovation had formed the indispensable core for telephony's growth up to , but was even more significant to the future because so much of it was fundamental: Perhaps more significantly, the application of scientific methods to solving the "system" problems of telephony set a pattern that influenced industrial research and development by demonstrating the power of these methods and developing techniques of management that encouraged their use.
OR specialists need to consider these opposing interests in their programming models. However, so far, OR models often ignore the different hierarchical levels.
While linear programming is primarily used for budget allocation problems, integer programming IP is mainly used for staff-scheduling problems. A currently widely discussed IP staff-scheduling problem among management scientists is the staffing of construction workers. Management scientists continuously revise their models for improvement. However rapid innovations in construction technologies, transportation and infrastructure force management scientists to revise and further improve their models frequently.
Management Science is crucial for the construction industry. While we demonstrated that the application of operational research theory allows cost savings and service improvements for the construction sector, we also discovered future challenges for management scientists. Our researchers at Building Radar discovered the following fields:. I like to know the role of consultant engineer in the construction industry. Are OR techniques really useful for the construction industry?
Management Science Publications about the construction industry The threat of an ever-aging population has seen more management scientists pursuing scientific research from onwards. Linear Programming Methodologies within Construction Projects Within the construction industry, linear programming LP methodologies are applied to allocate resources and to develop plans on how to use these resources.
Do not simply minimize initial cost, but set long-term objectives! All players have conflicting interest about the research outcome A further complication for linear programming approaches in the construction industry lies in the hierarchical organization within the construction industry.
OR findings are constantly disrupted by rapid innovation While linear programming is primarily used for budget allocation problems, integer programming IP is mainly used for staff-scheduling problems.
Requirements for services and developing a service: Based on a decision tree model that was developed from a survey with 71 participants, construction company types were identified for whom video—telephone consulting worked effectively. As a result, video—telephone consulting was discovered as an alternative to existing onsite services. To do so, a system dynamic simulation model was developed.
With the help of this model, two different interventions were tested in order to be optimally prepaired for upcomming budget cuts and unexpected building damage. Allocating resources for delivering services and developing programs and plans that will use these resources in delivering services: Based on a 4-year planning frame, the model allows us to derive conclusions on the optimal number of construction workers to train, promote, and recruit.
Developing criteria for delivery performance and managing the performance of delivery: Peter and Ludwig investigated different stochastic integer programming models to develop building phase schedules in regards to the availability of the work force. Based on these models, heuristics for human resource scheduling were derived that allow us to minimise the expected shortage of missing construction workers. Evaluating the results of construction delivery: To find out the minimal cost of a standardized construction side, operational researchers investigated the optimal materials and resource allocation based on a decision model.
Our researchers at Building Radar discovered the following fields: Management science theory needs to become more practical and less academic. This would allow more practitioners to apply the concepts. This opens new opportunities for management scientists. Management science research from the perspective of the architect or general contractors is quite advanced, while management science research from the perspectives of building owner or future tenant is in its infancy.
There is much catching up to do, as the latter perspective becomes increasingly relevant! The impact of costs on construction outcomes is hard to measure, but crucial for management scientists for developing accurate models. More accurate solutions need to be found, especially on tracking the construction project of a tenant after the construction of the building is completed.
An ongoing challenge for OR specialists is to reflect the opposing interests of different stakeholders within construction sides that result from their hierarchical organization.
Integer programming is for example used to managing human resource allocation. Rapid innovations in construction technologies, transportation and infrastructure force management scientists to revise their IP models frequently. Ready to revolutionise your construction lead generation?
