Integrating applications for the construction industry using a STEP-based integration platform (SIP)

Abstract: International construction industry has not still achieved a high degree of integration and automation in the past years. The European ESPRIT III project number 6660, RoadRobot (Operator Assisted Mobile Road Robot For Heavy Duty Civil Engineering Applications) intends to design and to implement an architecture to support the integration and automation tasks in that domain. To aid the implementation of the architecture, a STEP-based (ISO 10303) platform for integration of applications (SIP toolkit), was developed by UNINOVA. The general purpose of SIP is to assist the achievement of standardised Computer Integrated Manufacturing (CIM) environments, providing a set of development system tools. Last year, during CIB W78 and TG10 held at the University of Stanford - California (USA), SIP and the aim of the RoadRobot project were presented. During the CIB‘96, the RoadRobot architecture and its achieved results will be shown, as well as the improvements of SIP made in order to meet the project requirements. Special care will be taken concerning the problems found and the solutions adopted.

Integrating applications for the construction industry using a step-based.integratlon platform (sip)-seeking a life-cycle-oriented modelling -

Abstract: International building industry has not still achieved a high degree of integration and automation in the past years. Up to now, the use of Information Technology (IT) in outdoor applications, specially in the building industry and automated construction, should have more attention. For that reason existing architectures and modules from other industrial areas can be adapted to the special requirements of the building industry. Because the use of standards in the modelling process can help the integration task, a STEP (IS010303) based platform for integration of applications (SIP toolkit), created by UNINOVA in the ambit of an European project, was developed. Several managerial and engineering applications were already integrated in industrial environments using SIP, including the construction one. Demonstrations are available showing achieved results. The paper mainly concentrates on the following aspects: -Discussion about integration of software tools in industrial environments, under standardisation of information modelling. -Presentation of the internal architecture of the platform, and the global information system architecture implemented. -Comments about the results and experience acquired during the implementation of SIP in R and D projects and in industrial companies, specially in the European Project for road construction - RoadRobot.

Integration of planning and control activities for building and construction: experiencing standards

Abstract: The effective exchange of information regarding the planning and control activities (schedules, resources, materials, cost, cash flow) between the different parties involved in building and construction projects is a critical success factor to avoid projects' time and costs overrun and to insure better quality. However, current applications and research and development efforts on electronic exchange of information are usually restricted to the exchange of technical design information, particularly CAD exchange amongst designers and between these and contractors; and of business data (purchase orders, invoices, remittance advice, etc.), between contractors and builders, merchants and suppliers. This paper will review current practitioners' approach to the exchange of planning and control information, and discuss the business need to the seamless flow of scheduling, resource, materials, and cost information between firms. Different technical solutions available to address the subject will be described. Through the description of the experience in this area of two European projects, RoadRobot and SUMMIT, the paper will also describe the state-of-the-art regarding the development of international standards for the exchange of planning and control information, particularly at the EDIFACT, STEP and IAI levels. RoadRobot - Operator Assisted Mobile Road Robot for Heavy Duty Civil Engineering Applications, was a project devoted to implement a general standard-based architecture to support the information management for road construction environments, covering from the road design to road construction, embracing the site, cell, machine and tool levels. SUMMIT - Supply Chain Management In Construction Industry, is an end-user driven project which envisages the creation, implementation, test and evaluation of an EDI, STEP and IAI/IFC based communication infrastructure on a specific project of building prefabricated houses, connecting project manager, contractor and suppliers. This paper shows that international standards for planning and control information in B and C are not yet enough developed and that further developments are required.

The road model - roadrobot’s experience in applying standards to road construction process’ models

Abstract: "This paper starts by presenting, in short, the architecture developed within European Project ESPRIT III 6660 RoadRobot (Operator Assisted Mobile Road Robot For Heavy Duty Civil Engineering Applications), that aimed towards the full automation of road construction sites. The purpose of the architecture was to lay the basis for the development of a system capable of integrating a set of applications in a common architecture based on the use of a standard (ISO 10303-STEP). The presented architecture has demonstrated the full integration of information and control, starting by loading the information from the selected CAE system (InRoads from Intergraph), down, through the intermediate steps, to the automatic control of a Road Paver from German manufacturer VÖGELE. The main focus of the paper is on the standard-based information models that have been developed to represent project information throughout the road construction cycle. The initial Road Model Kernel created by TNO has been extended to support road specifications that include an update on the specification of asphalt layers for road paving, but also the addition of geological information for the specification of excavation tasks. A set of models has been developed for the maintenance of information regarding planning and scheduling of tasks, which takes into account the project information. A model for resources is used form maintaining resource information for allocation during planning and scheduling. Finally a control model has been developed for control of execution of tasks. The RoadRobot has demonstrated the use of this architecture, and its underlying information models on a demonstration where information downloaded from the CAE system has made its way to a road paver who paved a road segment without on-site human intervention."

An architecture for heavy duty machine controllers-foreseeing automated road construction environments

Abstract: Considering the architecture designed for the overall incorporation of information technologies (IT) on road construction environments, this paper focuses on the development of automated machine controllers, and on the underlying requisites of machines to use these controllers. Special attention is paid to the modules that compose the machine controller. This work was developed within European Project ESPRIT III 6660 RoadRobot (Operator Assisted Mobile Road Robot For Heavy Duty Civil Engineering Applications).
