The concepts of 'sustainable development', 'sustainable construction' and 'green building' have been elevated to priority levels in all types and phases of construction project development worldwide. Consultants and contractors are now required to seriously consider the impact of their operations on the natural environment and the society, and consequently adopt sustainable construction practices in the development process to minimize and mitigate the negative impacts of their activities. However, existing sustainability rating tools apply to the design, post-construction and operation phases of a building; no tool exists for the rating of the performance of the contractor or the project team at the construction phase. This study aimed to develop a model for evaluating the sustainability of construction operations, drawing on the global best practice standards on sustainability. Practical applications of the model were carried out through case studies to evaluate the performances of fifteen construction firms in New Zealand. The developed model and the outcomes of the case studies were presented, including potential areas of weaknesses, strengths, constraints to achievement or adoption of sustainable construction practices and areas for improvement in the operations of the firms. The successful application of the developed model in practice shows its usefulness and ease of application. It is therefore recommended for adoption as a simple but effective system for measuring and reporting on sustainability performance or sustainability of construction operations of firms in New Zealand and elsewhere.

In the past, a strategic management of work demands has been increasingly challenged to design-build (DB) firms. Such a management is capable of providing sufficient profitable impact of a project on them. Total project profit is mainly related to actual resources, work completion time, amount of rework, and costs. The degree of recycling work packages in the DB project delivery system is used as a measure of the quality of the performed work. However, there are few models available to evaluate the impact of a demand management strategy on the DB firms and to predict its behavior. We propose a decision-making support model as an aid for assessing the amount of rework and for predicting project profit resulting in a convincible demand management strategy. This model is constructed by using a dynamic feedback approach that can analyze the problems arising in complex managerial systems. For the purpose of illustration, widely acceptable strategies were applied into the model to explore their impacts on the DB firms. The results indicate that the model is helpful for the managers in selecting the most appropriate demand management strategy for successfully achieving their objectives.

In the IT(Information Technology) service, which supply the solutions related to business management and IT, network construction and application trends, the related service business are increasing according to the enlargement of project scope and the diversity of project types as the need of service customers. In this paper, I propose the significant effect factors on the network management of IT service firms. The key findings are from the analysis result about 94 IT service firms as follows. For implementation the high performance of network management in the IT service firms, the strategic elements in the process of network construction are more conceived highly than the basic element in them. Also the perspective of project objectives are considered than the nominal perspectives in the partner selection process. The competency of partner firms', the cooperation process between the partner firms', network relation operation management and network relation structure management are the significant effect factors of network management.

Intellectual capital is one of the most valuable assets of any enterprise. This empirical investigation examines the causal relationship between intellectual capital and the performance of architecture firms. More than 100 architecture firms across Taiwan have each been assessed for the levels of human capital, structural capital, relational capital, and business performance. The results suggest that the architecture firms exhibit higher levels of relational capital. However, the firms indicate relatively low levels of human capital. Additionally, the results from the correlation analysis suggest that all the four measures (human capital, structural capital, relational capital, and business performance) are highly correlated. The findings from the path analysis also indicate that human capital may influence the performance of architecture firms via structural capital and relational capital.

해외건설업이 국가경제에 기여하는 중추 산업임에도 불구하고, 기존의 해외건설 실적에 관한 연구는 단편적인 동향이나 특정 시점의 시장 점유율을 분석하는데 집중해왔다. 해외건설업은 프로젝트 기반산업으로 분절적이고(fragmented), 여러 다른 업체로 구성되며(heterogeneous), 업황에 따라 시장 구조가 역동적으로 변화하는(dynamic) 특성을 가지고 있어 특정 시점에 대한 정태적 분석과 함께 동태적 시장 변화의 고려가 필수적이다. 본 연구에서는 2000년부터 2017년까지 국내 건설기업이 계약을 체결한 9,173건의 프로젝트 정보를 활용하여 우리나라 해외건설 계약실적 구조를 분석하였다. 산업 차원의 실적정보를 정태적(시장 집중도), 동태적(시장 이동성 및 불안정성)으로 구분하여 분석하였으며, 구체적인 방법론을 기술하였다. 분석 결과, 정태적 측면에서는 국내 건설기업의 해외건설 경쟁구도가 최근 더욱 치열해지고 있으며, 동태적 측면에서는 주요 지역 및 공종을 제외한 대부분의 경우 시장 지위가 미약하고 불안정한 것으로 밝혀졌다. 본 연구는 정태적 동태적 분석의 조합을 통해 건설 관련 주체들의 시장 이해도를 제고하고, 향후 경쟁전략 수립을 위한 기초자료를 제공하였다는 점에서 의의가 있다.

Global construction and engineering consulting (E&C) firms are actively seeking entry into overseas markets based on loan projects from multilateral development banks to provide a basis for entry into overseas markets and sustainable growth. Bids on these projects are competitive between global top firms in terms of the technical level and price due to the limited number of projects; thus, developing a successful partnership to complement competence has become an essential element to win bids. In this regard, many studies have analyzed enterprises through characteristic analyses or the derivation of influential factors from the past social networks based on social network analysis (SNA). However, few studies have been conducted to reflect the process of changes to analyze collaborative relationships. Thus, this study aims to identify dynamic changes in past social networks and develop a model that can predict changes in the relationships between E&C firms based on similarities or differences between firms, presenting a methodology to target firms for appropriate collaboration. The analysis results demonstrate that the sensitivity of the developed prediction model was 70.26%, which could accurately predict 163 out of 232 actual cooperative cases.

After the construction participants system is abolished, expectations are high for its consequences such as liquidating paper-companies, holding back low price contracts, and improving multi-stepwise subcontract structure. However, the professional construction firms have been took responsibilities and obligations as businessmen employing the chief workmen and construction workers. For this reason, it is expected that they will be charged a great deal of expenses such as increase in labor management services and laborers, the occurrence of an retirement grants, insurance fees, etc. Since the hold on power of field managers are getting weaker toward the construction workers, it is most likely to have loss in efficiency of production in the long term. Therefore purpose of this research is to analyze difficulties and the point at issues with which professional construction firms are undergoing after abolishing the construction participants system by investigating on the actual condition in the field management. For this research, we got a grip on the actual condition and analyzed the rise of a primary factor on reinforced concrete construction.

The performance measurement of construction firms is considered as a competitive advantage to develop and improve their performance to have place in the market and stay able to face the continuous challenge. Egyptian construction firms (ECF) started recently to adopt quality management system (QMS) as a way to develop and improve their performance as previous studies showed. However, measuring that performance to include all the firm's aspects in a competitive way is a crucial process for the ECF's culture. The research is trying to indicate the role of the QMS implementation in measuring performance (MP) through developing a model for measuring performance on the organization level, and explore its impact on the organization that adopt quality management system. This model is based on specific elements and their related indicators which have been derived from national approaches and models of measuring performance (benchmarking, quality awards and six sigma).Elements determination and the status of their real practice has been investigated through a questionnaire to a representative sample of ECF. This model determines the performance level (PL) of the organization that measured by a mean of a point system. Weights of the elements in the point system considered both the elements' importance in the international models and its real practice in the Egyptian construction firms. So, the final outcome of the model reveals the level of firm performance that helps the firm to identify the weak points against the strong ones, Confirm the priorities and identify new opportunities for developing, and Check the position of the company in the market among the others. Another questionnaire has been developed to be distributed on a group of Experts on measuring performance for the purpose of model validation. The majority of surveyed experts agreed that the proposed model can be applied effectively.

CM시장에서의 경쟁이 심화되고 있는 상황에서 CM기업이 경쟁우위를 점하는 것은 매우 중요한 기업 현안이다. 이를 위해서는 적합한 경쟁전략을 갖추어야 하고 이를 통해 지속적으로 경쟁우위를 확보할 필요가 있다. 본 연구의 목적은 CM시장에서 경쟁우위를 점하기 위해 CM기업들이 중요하게 여기는 경쟁전략요소를 분석하고 이들 경쟁전략요소에서 나타나는 주요 특징과 시사점을 도출하는데 있으며 마이클 포터(Michael Porter)의 경쟁전략모델을 분석방법론으로 활용하였다. 연구 결과, 상위그룹에서는 차별화전략을 중요시 여기는 반면, 하위그룹에서는 집중화전략을 중요시 여기는 것으로 나타났다. 그러나 원가우위전략은 상하위 그룹에서 동일하게 상대적으로 중요도가 낮은 경쟁전략으로 인식되고 있는 것으로 나타났다. 비록 상하위 그룹에 따라 각 경쟁전략요소의 세부적인 순위에는 차이가 있었지만 종합적으로 보면 특화된 CM서비스 제공이 중요한 경쟁전략요소로 인식되고 있었다. CM기업의 경쟁전략요소에 대한 이해는 현재 CM기업들이 중요하게 생각하는 경쟁전략의 방향성과 내용을 파악할 수 있게 하며 향후 자사(自社)의 경쟁전략 수립을 위해 유용하게 활용될 수 있다.
