The Cathedral Hill Hospital (CHH) project is a 1.2 million square feet urban replacement hospital in San Francisco, California. It is not just designed to be a stateof- the-art hospital but also to break new grounds in multiple areas of design, construction, and operations. Since the beginning of project validation in 2007, the Integrated project Delivery Team has been applying and testing Lean ideas, concepts, tools and processes to develop this very complex project. The paper's nurturing proposition is that CHH has implemented most principles related to the Lean product development system at Toyota, as described by Morgan and Liker, and that these principles are the foundation for the evolving operational system that supports its processes on a daily basis. The paper attempts to compare and contrast initiatives set forth at CHH with the 13 principles proposed by Morgan and Liker regarding the Toyota Product Development System. Additionally, the paper aims to explore the opportunities and limitations of experimenting and implementing Lean Product Development ideas and practices into design and engineering of the CHH project.

Building Information Modeling (BIM) and Lean Thinking have been used separately as key approaches to overall construction projects' improvement. Their combination, given several scenarios, presents opportunities for improvement as well as challenges in implementation. However, the exploration of eventual interactions and relationships between BIM as a process and Lean construction principles is recent in research. The objective of this paper is to identify BIM and Lean relationship aspects with a focus on the construction phase and from the perspective of the general contractor (GC). This paper is based on a case study where BIM is already heavily used by the GC and where the integration of Lean practices is recent. We explore areas of improvement and Lean contributions to BIM from two perspectives. First, from Sacks et al.'s (2010) Interaction Matrix perspective, we identify some existing interactions. Second, based on the Capability Maturity Model (CMM) of the National Building Information Modeling Standard (NBIMS), we measure the level of the project's BIM maturity and highlight areas of improvement for Lean. The main contribution of the paper is concerned with the exploration of the BIM maturity levels that are enhanced by Lean implementation.

The paper presents the findings of a study conducted at a large 360-bed and 730,000+ square feet hospital in Southern California. The main purpose of the study was to investigate the work flow of trades working on the project site and to identify problems that prevent a continuous flow of work of dry wall, electrical, and mechanical trades working in different rooms. Data was collected through different methods including direct observation of the work and trade meetings, document analysis, value stream mapping, and interviews. The paper focuses on a specific area of the project related to building repetitive units (rooms and bathrooms). A large portion of the lead time to complete the units was related to waiting/idle times resulting from problems in the information flow and especially how people make commitments to execute these tasks. © 2012 ASCE.

International Journal of Pavement Research and Technology 2010年第4期3卷 223-227页

作者： Krezel, Zbigniew Adam McManus, Kerry Construction Management Program Faculty of Science and Engineering Deakin University Melbourne Australia AUSLINK Low Volume Roads Initiative Project Faculty of Engineering and Industrial Science Swinburne University of Technology Melbourne Australia

This paper reports on the second phase of a research project aimed at the development of an environmentally friendly noise barrier for urban freeways, also known as KMAK [1]. The concrete barrier, which has some unique capabilities to mitigate transportation noise, is made from recycled concrete (RC) aggregate and industrial by-products such as fly ash and reclaimed water. The current developmental work expands on a research project that resulted in a two-layer (2L) concrete barrier. Two prototypes of the 2L barrier were produced, followed by extensive acoustic testing and a number of simulations where standard timber and/or concrete barriers were substituted with KMAK barrier [2]. Current research investigates a variety of architectural finishes applied to the original KMAK barrier with the aim of improving its visual appearance and also fine-tuning its acoustic performance. The new three-layer (3L) barrier optimizes sound absorption in a frequency range characteristic similar to that of transportation noise, especially road traffic noise. Three major aspects related to the development of architectural finishes were considered;environmentally responsible materials, surface features, and production methods. The findings of the current investigation demonstrate that there is a positive correlation between surface features, percentage of perforation as well as depth of the architectural layer, and increased potential of the 3L barrier to mitigate transportation noise. On average, the addition of perforated architectural finish contributes to a 20% increase in sound absorption. The preliminary results also show that the sound absorbency of the 3L barrier can be better controlled and tuned to specific noise frequency than the 2L type. The visual appearance has been significantly improved with the addition of the architectural finish, which makes the barrier an attractive, feasible, and viable alternative to road barriers made from standard concrete or timber. © Chinese

This paper establishes a model to identify the mechanism of selecting contractors by public sectors;and, by using indifference curve, to explain exchangeability between the most advantageous bid and the lowest bid. Literature reviews the concepts of procurement and economic discussions to support the procurement and consumer behaviors. With the viewpoint of consumer behavior, a model based on indifference curve theory is found utilizing mathematical hypotheses and construction. It is proved that a power function as well as an indifference curve, named Chen-Kuo curve, exists with satisfaction of statistical evaluation. Exchangeability between the most advantageous bid and the lowest bid is also provided to support the mechanism of a public sector's contractor selection. The contribution provided by this paper to both practice and research is that a conceptual methodology is introduced to reasonably explain procurement behavior, and a solution is for contractor selection by a public sector.

14th Annual Conference of the International Group for Lean construction, IGLC-14

作者： Polat, Gul Ballard, Glenn Construction Management Program Department of Civil Engineering Istanbul Technical University Istanbul Turkey Lean Construction Institute 4536 Fieldbrook Road Oakland CA 94619 United States Project and Engineering Mgmt. Group Dept. of Civil and Env. Eng. University of California at Berkeley United States

The authors have previously explored the practices of Turkish contractors in a series of papers, using rebar as the focal point. The exploratory studies have revealed a very complex socio-technical-economic system in play, the upshot of which is that performance is far from lean. This paper looks at the problem as representative of those faced by the construction industries in developing countries. First the system elements and dynamics are described, using force field analysis as the organizing tool. Then proposals are made for moving the industry toward lean construction practices, including optimal use of off site fabrication.

13th International Group for Lean construction Conference, IGLC 13

ISBN: (纸本)1877040347

Off-site fabrication of materials is a key feature of lean construction. However, the tradition of the industry has long been to fabricate materials on-site, and there are various factors that compel contractors to continue that tradition. These factors are especially powerful in developing countries. As an example, there is a strong preference for fabricating cut & bent rebar on-site in the Turkish construction industry. Using open-ended interviews, this study identifies the reasons for that preference and offers recommendations for improving off-site fabrication performance in Turkish construction. This study suggests that the preference for on-site fabrication of cut & bent rebar is based on the lack of management capability of contractors including the poor coordination capability and the defective ordering procedure, and it enables contractors to fiddle the numbers on workers and scrap in order to increase the money they receive from clients. The paper hopes to make a contribution to the theory and practice of lean implementation, especially in developing countries.

Most Turkish contractors prefer on-site fabrication of rebar due to several factors most of which are peculiar to developing countries. Therefore, the economics of on-site and off-site fabrication of rebar need to be compared in the project environment, which is subject to most of those factors, and it should be answered whether the strong preference for on-site fabrication is more economical than off-site fabrication in developing countries, namely in the Turkish construction industry. This study presents an economical comparison of the on-site and off-site fabrication practices of rebar by means of a simulation model that makes use of actual data obtained from a trade center project in Istanbul, Turkey. The study suggests that had the off-site fabrication practice been used in the project in Istanbul, the total cost of rebar would have been 1.2% higher than the total cost of rebar in the on-site fabrication practice. This finding also reveals the need for 'infrastructural' changes in the Turkish construction industry before its participants can enjoy the benefits of lean construction;a change that may be necessary in some degree for other developing countries as well.

He obtained his Master's degree in science and engineering from The Johns Hopkins University in 1997 with a dual major in program management and operations management. He has been with NAVSEA Naval Surface Warfare Center Carderock Division for over 16 years. He spent four years with the Hydromechanics Division computerizing the Model Design Group two years with the Large Cavitation Channel Project as a project engineer six years with the Ship Building Technologies Department as a task area manager managing research programs the past 3 ½ years with the Strategic Sealift Program as the ship design manager for Avondale's new con-struction and as the deputy assistant program manager for post delivery and NASSCO's new construction. Currently Mr. Lynaugh is the on-site ship design manager for LHD-8 at Ingalls Shipyard in Pascagoula Mississippi.

Cracking was discovered in the openings of cargo deck tie down fittings on ships under construction. There was a distinct possibility that these cracks could propagate through the fittings and into the strength deck plating, affecting the ships hull integrity. With more than 14,000 fittings installed on each ship, the appearance of approximately 400 cracks at the mid-ship area of the main and lower decks raised production and operational concerns. This paper will discus the successful application of a Root Cause Failure Analysis (RCFA) methodology employed by a Corrective Action Team (CAT) establish to solve the problem. Through their efforts and the systematic application of RCFA, various failure hypotheses were validated or discounted and consensus was achieved on the appropriate corrective action.

The road to Impeccable -: An uncommon approach to ship acquisition

引用

NAVAL ENGINEERS JOURNAL 1999年第3期111卷 245-255页

作者： Shen, TWT Proctor, BL Saha, D Mr. Terry Shen:is the Assistant Project Manager for the Ocean Surveillance Ship (T-AGOS 23) Acquisition Project at Naval Sea Systems Command (NAVSEA). He is responsible for the program management of the large SWATH (Small Waterplane Area Twin Hull) ship construction in the Gulf region. Mr. Shen has over 14 years of experience in ship acquisitions and has co-authored several technical papers published by the Association of Scientists & Engineers the Society of Naval Architects & Marine Engineers and the American Society of Naval Engineers. He is a graduate of the University of Maryland with a BS in aerospace engineering and a BA in speech communication a 1986 graduate of the DSMC Program Management Course and a 1991 graduate of the Virginia Polytechnic Institute with an MBA in business administration. Mr. Barry Proctor:is NAVSEA's Ship Design Manager for the T-AGOS 23 program. He has held this position since March 1997. Prior to that time he was NAVSEA's Ship Design Manager for the T -AKR 300 class vessels. He has over 18 years of experience as a Naval Architect for NAVSEA (O3D). He has a BS in civil engineering from the University of Maryland and an MS in naval architecture and marine engineering from the University of Michigan. Mr. Deepak Saha:provides design support to NAVSEA's Program Office and Ship Design Manager on the T -AGOS 23 ship acquisition. His involvement with the program started at the time the first shipbuilder declared bankruptcy. He is Manager of the Commercial Ship Design Group at M. Rosenblatt & Son Inc. (MR&S) Arlington Branch. He has over 26 years of experience as a marine engineer and naval architect. He obtained a BS in marine engineering from Calcutta India in 1972 and a BSE in naval architecture from the University of Michigan in 1983. He also holds a Chief Engineer's License (Unlimited Horsepower Diesels).

The road to the acquisition of the USNS Impeccable (T-AGOS 23) has seen a few uncommon and challenging twists and turns, resulting in delays and disruption to the program. The saga began in 1993, when the original shipbuilder, facing financial difficulties, filed for Chapter XI bankruptcy protection. For two more years the program was stalled before the Navy was able to warrant the work that had been done up to that point. In 1995 the contract was reassigned to another shipbuilder to complete the vessel and obtain the necessary certificates to comply with all the applicable requirements of the American Bureau of Shipping (ABS). This unprecedented approach put the Navy in the unique situation of being responsible for two of the most controversial issues in a ship construction process, i.e., detail design and equipment warranties. This paper gives the status of the program, discusses how various technical issues and production demands are being addressed, and describes the future hurdles that need to be overcome before delivery of the vessel.
