With respect to plant engineering and building services designs, 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 infrastructure protection and defence systems designs, the most widely used method of blast effects analysis depend 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 reckoning, it may underestimate or overestimate the peak reflected overpressure, impulse and shock-front arrival time on the face of a rigid surface. Despite this, such method 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 explicit nonlinear dynamics modelling and simulation will be performed. The strategy which we adopts, involves the use of both methods, will save time and simultaneously provides a 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 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 technologies. In our design services, we offer plant engineering design, infrastructure protection design, building services design and defence systems design. As for simulation services, we offer computational fluid dynamics (CFD), finite element analysis (FEA), fluid structure interaction analysis (FSI) 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 Australian Standards, API, British Standards, European, Eurocode, UFC, FEMA, NATO AASTP-1 & 4 and the Singapore standards.

Dr Jimmy Lea holds a Bachelor of Engineering degree from the University of New South Wales (UNSW '95), Sydney Australia and has 20+ years of direct experience in engineering and advanced simulation analysis. His Doctorate, sponsored by the Australian Defence Industries (ADI) and also awarded by UNSW, was focused on the applied research of engineering and CFD modelling and simulations to ensure the safe and efficient way of manufacturing rocket propellants, nitro-based high explosives, multipurpose bombs and warheads. He has completed formal training, sponsored by ADI, in explosives manufacturing and thermochemistry of explosives.
His experience includes spearheading advanced simulation of high explosive detonations, blast effects analysis and ballistic impact on various objects or targets of interest. He was the internal consultant in ADI-Land Ordnance and provided engineering mentoring to site engineers in subject matters related to aerial multipurpose bombs, rifle projectiles, high explosives, plastic explosives PE4, rocket propellants and warheads. He has presented in conferences in Europe and Asia Pacific region on simulation-related topics and has authored over a dozen of peer reviewed journals. Dr Lea is a Fellow of the Institute of Engineers Australia. Hitherto, his consulting firm has successfully delivered complex and challenging projects to clients based in Sydney, Melbourne, Perth, Singapore, Jakarta, Surabaya, Kuala Lumpur, Johor Bahru and other major cities within the Asia Pacific region.

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. I am glad to announce that this business model is working well since we have successfully exceeded our clients' expectations.
