The factors contributing to maintenance cost include the life‐long environmental factors that the building is exposed to during its useful life as well as parameters relating to the design, construction and maintenance processes. The performance of risk associated with these factors decides the future maintenance requirements of buildings. Ignoring these risks factors generally result in high maintenance costs. The purpose of this paper is to identify the maintainability risk factors and their implications on maintenance costs.

A survey based methodology was used to establish the risks factors of building maintainability. A sample of high‐rise buildings was selected to evaluate these risk factors that were identified through an extensive literature review and survey of substantive experts. Further, these risks factors were applied to a real case study.

A total of ten risk factors of maintainability were identified in relation to high‐rise buildings. They were analyzed using a case study and the implications on maintenance cost were evaluated. The results show that there is a considerable reduction in maintenance cost when these risks are minimized.

The research was limited to the USA and its six biggest cities. The results presented are predominantly qualitative and the results rely on extensive evaluation.

The paper provides useful information to the designers and users on the maintenance problems related to buildings. Also it highlights critical risk conditions that should be considered to minimize maintenance costs.

The aim of this research study is to develop a risk-based framework that can quantify maintainability to forecast future maintainability of a building at early stages as a decision tool to minimize increase of maintenance cost.

A survey-based approach was used to explore the risk factors in the domain of maintainability risks under tropical environmental conditions. The research derived ten risk factors based on 58 identified causes related to maintainability issues as common to high-rise buildings in tropical conditions. Impact of these risk factors was evaluated using an indicator referred to as the “maintenance score (MS)” which was derived from the “whole-life maintenance cost” involved in maintaining the expected “performance” level of the building. Further, an ensemble neural network (ENN) model was developed to model the MS for evaluating maintainability risks in high-rise buildings.

Results showed that predictions from the model were highly compatible and in the same order when compared with calculations based on actual past data. It further showed that, maintainability of buildings could be improved if the building was designed, constructed and managed properly by controlling their maintainability risks.

The ENN model was used to analyze maintainability of a high-rise building. Thus, it provides a useful tool for designers, clients, facilities managers/maintenance managers and users to analyze maintainability risks of buildings at early stages.

Artificial neural network (ANN) has been used for risk analysis in various applications such as engineering, financial and facilities management. However, use of a single network has become less accurate when the problem is complex with a large number of variables to be considered. Ensemble neural network (ENN) architecture has proposed to overcome these difficulties of solving a complex problem. ENN consists of many small “expert networks” that learn small parts of the complex problem, which are established by decomposing it into its sub levels. This paper seeks to address these issues.

ENN model was developed to analyze risks in maintainability of buildings which is known as a complex problem with a large number of risk variables. The model comprised four expert networks to represent building components of roof, façade, internal areas and basement. The accuracy of the model was tested using two error terms such as network error and generalization error.

The results showed that ENN performed well in solving complex problems by decomposing the problem into its sub levels.

The application of ensemble network would create a new concept of analyzing complex risk analysis problems. The study also provides a useful tool for designers, clients, facilities managers/maintenance managers and users to analyze maintainability risks of buildings at early stages.

With increased architectural, design and functional requirements and complexities, maintaining a modern building can easily become a costly affair. There is much evidence in the literature review as well as from the factual data, showing the significant increase of the maintenance budget in the recent past. This is due to the fact that, these complexities eventually generate many deficiencies and difficulties and, in turn, creates a tremendous maintenance workload and an undue budget. Therefore, the purpose of this paper is to discuss factors related to such issues in the form of risks involved in the maintainability of buildings and further, explore several strategies and industry actions at the industry level to resolve this burning problem. This paper is focused to address the condominium properties.

This approach of investigation of the risk factors was based on exploring the causes of existing defects and problems, which tend to lower the maintainability. Existing literature, site observations/interviews and questionnaire surveys were used to gather the required data.

There are 13 number of critical maintainability problems, 43 respective factors as “maintainability risk” factors and 12 subsequent industry actions for better maintainability, in the findings. In addition, nine maintainability strategies are explored based on the relevant risk conditions to enhance the maintainability at the organizational/project level and three industry motivators are extracted from the relevant industry actions. A simplified framework for maintainability is proposed based on the strategies and the industry actions.

The data collection has to be limited to the Colombo metropolitan region due to limited resources.

The paper provides useful information to the designers, clients, facilities managers/maintenance managers and users, on maintainability issues related to condominiums. This information highlights the important risk conditions, strategies and industry motivators in order to minimize these problems. These findings may provide an opportunity to promote “highly maintainable buildings for the future”.

The research into the issue of maintainability of multi‐storey buildings in Sri Lanka is still in its adolescent stage. One of the critical building elements that requires immediate attention for maintainability is reinforced concrete flat roofs. They are often subjected to alternate drying and wetting cycles under tropical conditions, causing many defects and subsequent deterioration when proper detailing related to design, construction and maintenance actions are lacking. Therefore, the aim of this paper is focused on identifying problems and risks and proposing a model to enhance the maintainability of flat roofs.

The existing maintainability problems were collected from 50 multi‐storey buildings. The inherent risks of flat roofs' maintainability were identified and analyzed through their problem‐causing factors. A scoring system using artificial neural networks is developed to forecast the level of maintainability.

The paper found 721 maintainability problems of flat roofs and a further 12 maintainability risk conditions related to the flat roofs were elicited. The model showed the level of maintainability of a typical flat roof shown is only 51 percent. The risk factors are also prioritized to give guidance.

The paper provides useful information to the designers and users on maintainability problems related to flat roofs. Also it highlights important risk conditions in order to minimize these problems.

The purpose of this organization research project was to focus on finding effective methods for the stakeholder group of private firms in the apparel and textile industry in Sri Lanka to work together as partners with government and academic institution stakeholder groups to raise the level of human resource development in education, training and technology innovation resources in the apparel and textile industry.

Organization development, action research and training methods were used to help the various groups examine their needs and issues, and the consultant's gap analysis was used to identify any dysfunctional barriers along three levels of realm, scale, and transform that formed a wicked problem situation that kept the stakeholder groups from organizing themselves to work together on the common cause.

The three stakeholder groups were able to make use of a variation of the public private partnership model in developing a virtual college of apparel and textiles.

The three stakeholder groups were able to use formal and creative informal forms of a partnership of partnerships approach by cross sharing of board members. Sri Lanka's apparel and textile industry was able to successfully upgrade its human resource development efforts to retain its strong position in the following years of global market change.

Using organization development's wicked problem resolution methods can be useful in any country that needs to bring large diverse groups of public and private organizations together to work on common interests while assuring that their differing missions can be pursued effectively.

The construction management literature discusses the benefits which companies derive from having their operations certified to the ISO 9000 series of quality management systems (QMS). In Singapore, quality has been a topical issue in the construction industry for the past decade. ISO 9000 certification, which has been a major part of the construction quality development programme, is now mandatory for large construction contracting and consultancy organizations wishing to register to undertake public‐sector projects. This paper reports on a study on the role which ISO 9000 implementation plays in the quality development of Singapore's construction industry by ascertaining the perceptions, objectives, motivations and experiences (including benefits and problems) relating to quality in general, and to ISO 9000 certification and implementation in particular. A questionnaire‐based survey of large construction companies was conducted. It was found that construction firms benefit from QMS certification, and face no significant problems with it. Recommendations are made for enhancing the benefits of ISO 9000 and ensuring that it has a positive long‐term impact on the development of Singapore's construction industry.
