We provide professional engineering services to industries such as the building & environment, chemical & petrochemical, critical infrastructure, food & beverage, renewable energy and water & wastewater. We differentiate ourselves in the way we approach a problem. Our standard approach involves 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 overdesign which eventually leads to higher overall fabrication and project costs. In a nutshell, our engineering consultants are supported by in-house simulation technologies to ensure effective & efficient deliverables. We provide services to clients based in Australia, Singapore, Indonesia, Malaysia and our scope of engineering services are:
- Plant Engineering Design

​- Blast Mitigation Design

- Building Services Review

- Complex Systems Review

We provide blast mitigation design services to defend critical infrastructure and public space against primary to quaternary blast injuries. Our scope of work includes:
- Advanced analysis that considers site, architectural and structural resilience of assets
- Calculation of positive and negative phases of blast wave parameters

- Blast wave and fragment effects analysis and their impact against structures and personnel
- Customised mitigation measures and recommendations to mitigate risks

- Mitigation measures will eliminate or reduce the severity of primary to quaternary blast injuries

We provide personnel protection against pressurised pipes and vessels explosion, particularly in chemical process plants classified as a major hazard facility (MHF). Our consulting engineers provide:
- Pipes and vessels explosion study, prediction of peak overpressure and gas dispersion analysis
- Advanced analysis of the consequences of pipes and vessels explosion

​- Prediction of radius of impact, buildings affected and the severity of the explosion

- Explosion mitigation measures and redesign of chemical or petrochemical plant layout
