A New Framework For Post Occupancy Evaluation Of Office Buildings, Abdullah Al-Khawaja, Craig Langston, Brian Purdey
A New Framework For Post Occupancy Evaluation Of Office Buildings, Abdullah Al-Khawaja, Craig Langston, Brian Purdey
Craig Langston
Over the last three decades there has been growing interest and attention placed on sustainability and the contribution made by the built environment. Environmental auditing applied to buildings has largely been concerned with energy/water usage and waste. This paper argues that post occupancy evaluation can be a useful tool in validating the performance of commercial office buildings in terms of key design objectives of human comfort and productivity, from the perspective of building inhabitants. A new assessment framework, with post occupancy evaluation at its heart, is developed based on a double-loop (learning) cycle for continuous process improvement founded on three …
Competition Environment, Strategy And Performance In The Hong Kong Construction Industry, Yongtao Tan, Liyin Shen, Craig Langston
Competition Environment, Strategy And Performance In The Hong Kong Construction Industry, Yongtao Tan, Liyin Shen, Craig Langston
Craig Langston
Given a changing competition environment, strategic management has become of essential importance to construction firms. Effective strategy enables construction firms to match their activities to the changing environment and achieve superior performance in competition. Therefore, there is a need for studying contractors’ competitive strategies. This paper does that in relation to the Hong Kong construction industry. The impact of competition environment on contractor performance, and the relationship between competitive strategy and performance are examined by a questionnaire survey. The findings show that competition environment has a great impact on contractor performance, and four generic competitive strategies have been applied by …

Modelling Built Asset Preformance In 3d Space, David Copray, Craig Langston, Jim Smith
Craig Langston
This paper describes current research into the performance ‘decay’ of built assets over time through the enumeration of physical condition, space utilization and triple bottom line reward. Applying a retrospective study of the Melbourne General Post Office (GPO) from 1841 to today, these three variables can be assessed and mapped in 3D space using Langston and Smith’s iconCUR model. An index comprising all three variables can be constructed to track the performance of this building over its life cycle to test whether traditional theoretical decay curves used in asset management have any practical value. Such an approach can be employed …
Modelling Property Management Decisions Using 'Iconcur', Craig Langston, Jim Smith
Modelling Property Management Decisions Using 'Iconcur', Craig Langston, Jim Smith
Craig Langston
Making appropriate decisions concerning the ongoing management of existing built facilities is an important activity for property and facilities managers. This paper describes the development of a new conceptual framework for making better decisions about built assets at an early stage in the process, with a view to identifying which course of action to pursue. The resulting model, known as iconCUR, uses a weighted matrix methodology to obtain performance scores for condition, utilization and reward that are capable of mapping property decisions in 3D space over time. Via a case study of a real project in Sydney (Australia), the application …
A Casual [Causal] Relationship Between Building Maintenance Market And Gdp: Hong Kong Study, Yong-Tao Tan, Liyin Shen, Craig Langston
A Casual [Causal] Relationship Between Building Maintenance Market And Gdp: Hong Kong Study, Yong-Tao Tan, Liyin Shen, Craig Langston
Craig Langston
Purpose: The purpose of this paper is to examine the causal relationship between the building maintenance market and GDP in Hong Kong. Design/methodology/approach: The Granger causality test is used to investigate the lead-lag relationships between the maintenance and repair work and GDP in Hong Kong. With regression analysis, the future trend of the maintenance market is forecasted. Findings: The results show that the growth of the economy will lead to the growth of the maintenance market, not vice-versa. And the building maintenance market in Hong Kong will keep increasing with the economy growth. Originality/value: This paper shows that the growth …
