Abstract

Risk identification often produces nothing more than a long list of risks, which can be hard to understand or manage. The list can be prioritised to determine which risks should be addressed first, but this does not provide any insight into the structure of risk on the project. Traditional qualitative assessment cannot indicate those areas of the project which require special attention, or expose recurring themes, concentrations of risk, or ‘hot‐spots’ of risk exposure. The best way to deal with a large amount of data is to structure the information to aid comprehension. For risk management, this can be achieved with a Risk Breakdown Structure )RBS) a hierarchical structuring of risks on the project. The RBS can assist in understanding the distribution of risk on a project or across a business, aiding effective risk management. Just as the Work Breakdown Structure (WBS) is an important tool for projects because it scopes and defines the work, so the RBS can be an invaluable aid in understanding risk. The WBS forms the basis for many aspects of the project management process; similarly, the RBS can be used to structure and guide the risk management process. This paper presents the concept of the RBS, and gives a number of examples drawn from different project types and industries. Although not necessarily based in FM, the concepts and experience can be applied to any project. The benefits of using the RBS are then outlined, including as an aid for risk identification or risk assessment, comparison of projects, providing a framework for cross‐project risk reporting, and structuring lessons to be learned for future projects. This paper shows how to use the RBS to gain these benefits.

Abstract

Purpose

The purpose of this paper is to propose a framework for the standardisation of the work breakdown structure (WBS) for building projects. This is based on the premise that buildings in general retain basic elemental options, and that there is a commonality of activities in the procurement of building projects.

Design/methodology/approach

To achieve the objective, the general practice of developing the WBS is investigated. This is achieved by means of an industry‐wide questionnaire survey designed to identify the most widely used criteria among UK construction organisations in segregating building works into packages. The survey also investigates the sequencing of these criteria across the WBS hierarchy.

Findings

The findings reveal that the most frequently used decomposition criteria in the formulation of WBS for building projects are elements, work sections, physical location and construction aids. The proposed framework is presented as a hierarchical decomposition of a building project based on these criteria. It allows for flexibility in level of detail while maintaining a rigid sequencing of the criteria based on their frequency of use.

Originality/value

This paper reports on a specific part of an EPSRC funded project that aims to investigate the application of computer vision techniques to the on‐site measurement of construction progress. The part reported in this paper addresses planning issues that will lead to automatic generation of work packages. Previous studies have focused on automating the planning aspect by associating individual components with schedule information. However, large construction projects usually consist of thousands of components. Planning and tracking progress at the level of the component is unrealistic in these instances. The standardisation framework reported in this paper will form the basis for automating the formulation of work packages, thus providing a uniform basis for tracking progress (based on computer vision) during project execution.

Abstract

Purpose

Asset inventory is an essential part of any building asset management system and is needed by such functions as condition assessment and deterioration prediction. Previous studies in asset management systems have suggested the use of one of the many standard construction classification systems, such as UniFormat or MasterFormat, in achieving the goals of asset management. However, each classification system has its unique features, and it has been developed for different purposes and may not necessarily be directly adaptable to asset management. A proper classification system is thus needed to achieve the goals of building asset management effectively. Such a system must take into consideration the objectives and functions of asset management. Therefore, the purpose of this paper is to establish a unified work breakdown structure (WBS)-based framework for building asset inventory.

Design/methodology/approach

The WBS-based framework aims to cover the entire lifecycle of an asset so as to provide the unified classification system for asset inventory. The proposed framework is developed based on appropriate building standards. Also, comprehensive levels of details are included for space functions and locations for all assets in any type of building. Furthermore, this framework takes into consideration utilities in any kind of building project. As such, the WBS-based framework proposed in this research endeavor provides the basis for effective asset management. An educational building case study is presented and discussed to demonstrate the effectiveness of the proposed framework for asset management.

Findings

The unified WBS-based framework for building asset management effectively classifies asset inventories and facilitates decision-making in asset management during the lifecycle of an asset.

Originality/value

This research synthesizes a unified WBS-based framework for building asset management, which allows for a more effective lifecycle building asset management.

Abstract

The heavy civil engineering industry (railways, sewage treatment, chemical and pharmaceutical facilities, oil and gas facilities, etc.) is one of the major contributors to the British economy and generally involves a high level of investment. Clients in this industry are demanding accurate cost estimate, proper analysis of out‐turn cost and cost escalation and a high quality risk analysis throughout the construction processes. Current practice in the industry has suggested that there is a lack of structured methodologies and systematic cost escalation approach to achieve an appropriate cost analysis at the outset of projects and throughout the construction processes. In this context the prime objective of this research work is to develop a structured cost escalation methodology for improving estimating management and control in the heavy engineering industry construction processes. The methodology is composed of a forecasting model to predict cost indices of major items in industry and a risk knowledge base model for identifying and quantifying causes of cost escalations. This paper, as part of the research, reviews and discusses a knowledge‐based model for applying a cost escalation factor. The cost escalation factor is made up of market variation, a risk element and a component for bias. A knowledge elicitation strategy was employed to obtain the required knowledge for the model. The strategy included questionnaires, interviews and workshops and deliverables came in the form of influences and their effect on project cost escalation. From these deliverables, the concepts of a decision support model and system specification for applying cost escalation to base estimates is proposed.

Abstract

Purpose

The relatively low capital cost and contributions to mitigating global warming have favoured the continuous construction and operation of nuclear power plants (NPPs) across the world. One critical phase in the operation of nuclear plants for ensuring the safety and security of radioactive products and by-products is decommissioning. With the advent of digital twinning in the building information modelling (BIM) methodology, efficiency and safety can be improved from context-focus access to regulations pertaining to demolition of structures and the cleaning-up of radioactivity inherent in nuclear stations. The purpose of this study, therefore, is to propose a BIM-driven framework to achieve a more regulation-aware and safer decommissioning of nuclear power plants.

Design/methodology/approach

The framework considers task requirements, and landscape and environmental factors in modelling demolition scenarios that characterise decommissioning processes. The framework integrates decommissioning rules/regulations in a BIM linked non-structured query system to model items and decommissioning tasks, which are implemented based on context-focussed retrieval of decommissioning rules and regulations. The concept’s efficacy is demonstrated using example cases of digitalised NPPs.

Findings

This approach contributes to enhancing improvements in nuclear plant decommissioning with potential for appropriate activity sequencing, risk reduction and ensuring safety.

Originality/value

A BIM-driven framework hinged on querying non-structured databases to provide context-focussed access to nuclear rules and regulations and to aiding decommissioning is new.

Abstract

This study proposes targeted modernization of the Department of Defense (DoD's) Joint Forces Ammunition Logistics information system by implementing the optimized innovative information technology open architecture design and integrating Radio Frequency Identification Device data technologies and real-time optimization and control mechanisms as the critical technology components of the solution. The innovative information technology, which pursues the focused logistics, will be deployed in 36 months at the estimated cost of $568 million in constant dollars. We estimate that the Systems, Applications, Products (SAP)-based enterprise integration solution that the Army currently pursues will cost another $1.5 billion through the year 2014; however, it is unlikely to deliver the intended technical capabilities.

Abstract

A change order is an order from an employer authorizing a variation. Success in managing change orders results in uninterrupted construction operations and an agreed final project cost as well as duration. One of the methods to manage change orders is to establish good communication and cooperation among project team members. Success of this method can be enhanced by developing and utilizing a web‐based change order management system that supports documentation practice, communication and integration between different team members in the change order workflow. This paper discusses our web‐based project management system, change order management system (COMS), to manage change orders using the Internet. In order to show COMS’ potential benefits, a test case was conducted for comparing the COMS with the conventional practice of change order management.
