Calvin Chiu

More than 9 years of environmental consulting experience, with specific expertise in aspects of environmental noise, air ventilation and pollution dispersion simulation, and soil contamination. Specializes in noise impact assessment, air quality impact assessment, hazard assessment, drainage and sewerage impact assessment, water quality impact assessment, safety, occupational and public health risk assessment.

• Participated in environmental studies under the statutory EIAO process for environmental permitting.
• Conducted numerous comprehensive environmental assessments, environmental monitoring and audit (EM&A) and independent environmental checking (IEC).
• Experienced with a number of impact assessment tools and methodology. Noise: standard acoustic principle, CRTN based in-house tool for road traffic, CRN for railway noise, other in-house developed models for railway noise, fixed plant noise, construction noise, reverberation and speech quality. Air quality: Gaussian models including ISCST, FDM and CALINE4, as well as CFD Modelling for chemicals, odour, dust and thermal assessment. Water quality: HSPF for non-point source simulation modelling and CORMIX for prediction of dispersion in the marine waters. Hazard Assessment: in-house developed tools for LPG, Towngas TM and toxic gas release.
• Familiar with environmental mitigation measures for both construction and operation of the projects.
