Through our physical offices in Sydney, Singapore and Jakarta, Jimmy Lea P/L has successfully delivered complex projects to many clients based in the following locations:
- Sydney, New South Wales
- Melbourne, Victoria
- Brisbane, Queensland
- Perth, Western Australia
- Jakarta, Indonesia
- Surabaya, Indonesia
Commercial, airport and train stations
Performing engineering design, calculations or modelling & simulations without proper knowledge may lead to misleading results that can eventually cause costly catastrophic consequences. In my engineering & simulation consulting firm, only qualified personnel are assigned to projects in their respective area of practice. In general, all my engineering professionals or simulation specialists at principal level have at least 15 years of relevant experience. In addition, to ensure the simulation results are accurate, we only assign personnel with a PhD qualification specialised in modelling and simulation. These simulation specialists are supported by engineering professionals to ensure their recommended solutions to the clients are practical, implementable and cost effective. We only use ANSYS simulation package which has heavily-validated physical modelling capabilities to deliver fast, accurate results across the widest range of multiphysics applications.
To consistently deliver high quality deliverables, all projects are subjected to my firm's stringent quality control system. Every stage is thoroughly checked and reviewed to ensure the inputs or results are accurate and make engineering-sense before being allowed to proceed to the next stage. This strategy prevents small errors emanating from each stage to snowball into a large error which ultimately affects the accuracy of the final results, designs or systems. Finally, by keeping the size of my firm small, this boutique size effectively enables my consulting firm to provide a much more personalised and highly focused professional engineering services to many clients.

Conceptual to construction
Conceptual, FEED and detailed
With respect to plant engineering and building services review, our standard approach includes using advanced engineering and in-depth analysis that goes beyond simply adopting rule-of-thumb guidelines. Whilst rule-of-thumb provides a starting point for most design works, it has the tendency to over compromise or overdesign which eventually leads to higher overall fabrication costs. Our systematic approach also includes studying the impact of recalcitrant process variables on desired plant or building performance and provide appropriate recommendations to minimise if not eliminate pecuniary losses, even before the plants or buildings are constructed.
With respect to protection from blast wave and complex systems review, the most widely used method of blast effects analysis relies on design table and charts. A uniform loading over the height or length of the component is assumed when using this method. Moreover, this method assumes either a spherical (explosion in an open space) or a hemispherical (explosion on a surface) and does not consider variations in charge shape, charge orientation and point of detonation within the charge. Therefore, whilst such one-size-fits-all method provides an instant estimation, it may under- or over-estimate the peak reflected overpressure, impulse and shock-front arrival time on the face of a rigid surface. Despite the shortcoming from this method, it is not obsolete but can be useful to rapidly assess different scenarios and shortlist those scenarios that have the highest probability of inflicting significant damage on the target. Then blast effects analysis using a more accurate method involving performance-based modelling and simulation will be conducted. The strategy that we adopt, involves the use of both methods, which will save time and simultaneously provides much more accurate final results.
Jimmy Lea P/L provides turn-key professional engineering services starting from initial advanced simulation analysis to determine the strengths and weaknesses of a given system, followed by conventional engineering design by a team consisting of multidisciplinary engineers and finally design verification by performance-based simulation to determine the effectiveness of the design. We take pride in our professionalism and we are passionate in our chosen areas of practice. We are highly focused on the engineering services we offer, supported by our in-house simulation capability. In our engineering services, we offer plant engineering design, chemical process engineering, plant hazard mitigation and building services review. As for simulation services, we offer computational fluid dynamics (CFD), fluid structure interaction (FSI) analysis, explicit dynamics analysis (EDA) and blast effects analysis (BEA). Hence, you can rest assured that you are dealing with highly experienced professionals who are specialised and knowledgeable in their respective disciplines. By focusing solely on a few core engineering services and employing highly qualified professionals to prepare the deliverables, we aim to preserve excellent technical competence in these core services and ensure our clients receive services of the highest engineering standards. We design according to standards and design codes of your preference such as American Petroleum Institute (API) Standards, Australian Dangerous Goods (ADG) Code, Australian Standards (AS), British Standards (BS), European Standards (Eurocodes), Federal Emergency Management Agency (FEMA) Guidelines, Good Manufacturing Practice (GMP) Guidelines, North Atlantic Treaty Organisation (NATO) AASTP-1 & 4, Singapore Standards, the Unified Facilities Criteria (UFC), IWA 14-1 and PAS 68.
Founded in Sydney Australia in 2011, we have gained recognition as the engineering and simulation consultants that provide performance-based engineering practice by combining conventional with computer aided engineering. Supported by our highly-qualified experienced multidisciplinary chartered engineers, professional engineers, specialist simulation consultants and technologists, we have successfully delivered many challenging & complex projects including blast effects consulting to clients located in Australia, Singapore, Indonesia and within the Asia Pacific region. We are recognised as a leading specialist consulting firm because we focus on very narrow areas of practice.
Our company is spearheaded and managed by Chartered Engineers (Engineers Australia) from various engineering and industry backgrounds who thoroughly understand the engineering industry requirements. We currently employ experienced multidisciplinary engineers, simulation specialists, technologists, project managers, drafters and administrative support staff based in Sydney and Singapore. Within our delivery team, all our disciplinary engineers and technologists possess formal tertiary qualifications from reputable universities whereas all our simulation specialists hold a PhD specialising in simulation, coupled with many years of experience across various industries. Overall, our disciplinary engineers, simulation specialists and technologists have a combined experience of over 50 years.

Dr Jimmy Lea holds a Bachelor of Engineering (Chemical Engineering) degree from the University of New South Wales (UNSW '95), Sydney Australia and has over 20 years of direct experience in engineering and advanced simulation analysis.
His PhD, sponsored by the Australian Defence Industries (ADI) and also awarded by UNSW, was focused on the applied research of CFD technology in real-world scenarios. The title of his PhD thesis was 'The computational fluid dynamics analysis and optimisation of process vessels used in the manufacture of military propellants and high explosives'
His professional interest is using the combined application of conventional engineering with modelling and simulation technology to design, improve, troubleshoot or optimise chemical plants. In addition, he is also interested in using modelling and simulation technology to predict the outcomes, perform correction if required, before any physical work commences particularly in the built environment sector and complex systems. He is equally interested in the application of empirical and numerical blast effects analysis to study the interaction between blast waves and the surrounding objects.
Dr Lea has presented in conferences in Europe and Asia Pacific region on topics related to performance-based design using simulation technology and has co-authored over a dozen of peer reviewed journals. Dr Lea is also an Industry/Professional Fellow at the University of Technology Sydney (UTS) and is a Fellow of the Institute of Engineers Australia in the following areas of practice: Chemical Engineering, Building Services Engineering and Systems Engineering.
