Claims for additional costs and time extensions result from a variety of events occurring during the course of construction. To enhance the chances of success, contractors submitting claims must closely follow the steps stipulated in the contract conditions, provide a breakdown of alleged additional costs and time, and present sufficient documentation. On the other hand, project owners need to follow an overall comprehensive step-by-step procedure for tracking and managing the claims submitted by contractors. The paper presents a claims-management process that could be used by all parties involved in construction. The process identifies the major informationgathering and decision-making milestones as well as the notice and substantiation compliance checkpoints, which are critical to the development of defense arguments as claims are addressed. It further emphasizes the use of tools such as simulation, scheduling, productivity, and economic analysis and other modeling techniques in judging the level of justification and reasonableness of submitted claims.
Knowledge management represents a strategic vision for developing an organization’s performance and its likelihood of success in dealing with future challenges in its industry. The case starts by discussing the importance of knowledge management in improving the competitive edge of firms in general and of consulting firms in particular. Then, the case discusses the process of building a knowledge management system in the structural engineering department at a leading engineering design consulting firm, based in the Republic of Lebanon. The knowledge, both tacit and explicit, needed during the design phase is identified and mapped according to the adopted design process, and an expert system was built to capture some of the tacit knowledge needed in the conceptual design stage of the process. In addition, an intranet Web-based knowledge management system was developed with the aim of helping diffuse both explicit and tacit knowledge.
Robotic industrial applications are very well established in the manufacturing industry, while they are relatively in their infancy phase in the construction sector. The need for automation in construction is clear especially in repetitive tasks. The excavation process, which is generally critical in most construction projects, is a prime example of such tasks. This paper addresses automation assistance in excavation. The work utilized the robotics approach towards the automation of a typical excavator model, whose structure closely resembled that of an industrial manipulator. A simulation package using Matlab was developed using several embedded design and analysis tools. Emulation was also carried out on the RHINO educational robot to confirm the simulation results. The constructed simulation package offered an integrated environment for trajectory design and analysis for an excavator while addressing the constraints related to the excavator structure, safety and stability, and mode of application.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
