DOCUMENTATION ERRORS IN INSTRUMENTATION AND ELECTRICAL SYSTEMS: TOWARD PRODUCTIVITY IMPROVEMENT USING SYSTEM INFORMATION MODELLING
Documentation errors have been identified as a significant problem within the construction and engineering industry. Errors contained with contract documents can contribute to loss of profit, reduced productivity, and cost and time overruns as well as contractual disputes….
ASSESSING THE IMPACT OF RFIS IN ELECTRICAL AND INSTRUMENTATION ENGINEERING CONTRACTS
The design and construction of infrastructure, resource and energy projects are complex and challenging, and their success is heavily reliant upon effective communication between members of the engineering and construction teams. Good design and engineering is effective when it serves its intended purpose and is constructible within desired budget….
A SYSTEMS INFORMATION MODEL FOR MANAGING ELECTRICAL, CONTROL, AND INSTRUMENTATION ASSETS
Asset management (AM) involves the balancing of costs, opportunities and risks against the desired performance of assets, to achieve an owner’s objectives. It also enables asset owners to examine the need for and performance of their assets and their respective systems at varying levels. Having appropriate and reliable information….
OBJECT-ORIENTED MODEL FOR LIFE CYCLE MANAGEMENT OF ELECTRICAL INSTRUMENTATION CONTROL PROJECTS
Electrical instrumentation and control (EIC) systems can account for as much as 60% of maintainable items as well as being critical to safe and efficient operations. Thus, it is imperative that as-built documentation is error-free and reflects precisely what has been installed. Yet EIC as-built drawing that are produced…..
SYSTEMS INFORMATION MODELING: FROM FILE EXCHANGES TO MODEL SHARING FOR ELECTRICAL INSTRUMENTATION AND CONTROL SYSTEMS
The mining industry in Australia is in a period of intense introspection as it seeks to improve its productivity and competitiveness in global markets. With mining projects experiencing increasing overruns….
TOWARD PRODUCTIVITY IMPROVEMENT IN ELECTRICAL ENGINEERING DOCUMENTATION
The purpose of this paper is to determine the unproductive time and additional cost to re-engineer a safety control system for a Floating Production Storage Offloading vessel that was originally engineered and documented in computer-aided design (CAD)….
MOVING BEYOND CAD TO AN OBJECT-ORIENTED APPROACH FOR ELECTRICAL CONTROL AND INSTRUMENTATION SYSTEMS
The quality of computer-aided-design (CAD) generated ‘As-built’ documentation is evaluated for a High Voltage Switchgear System (HVSS), which forms part of a Supervisory Control and Data Acquisition up- grade….
MINING GOES PAPERLESS
The mining industry is cutting time and costs with software that removes the seemingly endless series of drawings from the electrical design and management process. Chris Sheedy looks at the technologies, the efficiencies they are bringing, and how the effects will be felt across the engineering world….
SYSTEM INFORMATION MODELLING IN PRACTICE: ANALYSIS OF TENDER DOCUMENTATION QUALITY IN A MINING MEGA-PROJECT
A System Information Model (SIM), which is an object oriented approach, was retrospectively constructed from the documentation provided to assist the contractor with their tender bid preparation. During the creation of the SIM, a total of 426 errors and omissions were found to be contained within the 77 tender ‘drawing’ documents supplied to the contractor by an Engineering, Construction, Procurement and Management (EPCM). Surprisingly, 70 drawings referenced in the tender documentation, and the Input/Output lists and Cause/Effect drawings were not provided…..
MANAGING RAIL INFRASTRUCTURE FOR A DIGITAL FUTURE: FUTURE-PROOFING OF
Rail infrastructure that operates at its optimum will be economical and sustainable and thus positively contribute to the productivity and competitiveness of an economy. The health of rail infrastructure, however, needs to be monitored, measured and maintained, which falls within the remit of asset managers who are often charged with balancing costs, opportunities and risks against the desired performance of the assets and their respective systems at varying levels. Having appropriate and reliable information about an asset is pivotal for enabling asset management to support decision-making, planning and execution of activities and tasks of assets, particularly during operations and maintenance…..
