Project Highlights KUALA LUMPUR, MALAYSIA Leading environmental monitoring on Asia’s largest railway project – MRT Line 2 ACOEM’s 01dB partnered with Klang Valley MRT construction contractors, to provide ongoing noise and vibration monitoring for the Sungai Buloh–Serdang– Putrajaya Mass Rapid Transit Corporation (MRT) Line 2, a fully automated and driverless rail system on Kuala Lumpur’s massive rail transport network. Using its proprietary ORION system, construction-related noise and vibration were monitored on site, in one standalone, portable instrument producing accessible data that was immediate and identified the quantifiable relationship between noise and vibration. NEW DELHI, INDIA Cementing its reputation as the environmental monitoring provider of choice in India In 2018, the Delhi Pollution Control Committee (DPCC) made one of the largest investments in air quality monitoring technology ever made by an environmental agency in India by deploying an additional 20 Continuous Ambient Air Quality Monitoring Stations (CAAQMS) designed, manufactured, installed and commissioned by ECOTECH. 01dB Leads Environmental Monitoring on Asia’s Largest Railway Project - Malaysia’s MRT Main pic: Works underway for Malaysia’s MRT Line 2. Pic opposite: The ORION covers all vibrations created by human activity and offers unique features such as waterproofing and a battery life of 30 hours. TOGETHER 2018 Issue 3 After several years of noise monitoring for MRT, 01dB is now also focussing on the project’s vibration control. In 2012, 01dB and their partner in Malaysia began working with MMC-Gamuda KVMRT (PDP SSP) Sdn Bhd, the Project Delivery Partner of the Mass Rapid Transit Corporation on Phase 1 of MRT Line 2 – the largest railway project in South East Asia. MSungai Buloh–Serdang–Putrajaya MRT Line 2 is a fully automated and driverless rail system that forms part of the larger rail transport network in the Klang Valley area near Kuala Lumpur, Malaysia. The partnership was developed and championed by ACOEM Asia Managing Director, Patrice Pischedda. During Phase 1 of the project, 01dB integrated their DUO noise monitoring system to ensure effective noise measurement and compliance with the Malaysian Department of Environment (DOE)’s planning guidelines. Due to the success of Phase 1, Patrice was approached by the developers to provide a vibration monitoring solution that could be used in parallel with DUO. New vibration technology complements 01dB Across the sub-continent, ECOTECH operates, maintains noise monitoring instruments and collects data The launch from of more ORION in than mid-2016 100+ gave Patrice CAAQMS the systems; opportunity to extend 01dB’s relationship with the MRT comprising hundreds Line 2 project. of The individual portable, DIN 45669-compliant pieces of equipment; ORION was introduced into PHASE 2 of the construction process recording thousands of environmental monitoring data sets. and will continue to be used throughout Phase 3 to project completion, which is expected in 2021. Through ECOTECH, ACOEM empowers dozens of Indian ORION guarantees international standards compliance state pollution control committees, businesses and ORION was used for Phase 2’s baseline monitoring (the industries to meet ambient their vibration air level quality measured analysis prior to construction and reporting works) and will continue to be utilised throughout the obligations every day, 365 days a year. duration of piling works along 52.2 km of track, of which 13.5 km is underground. ORION’s measurement of Peak Component Particle Velocity (PCPV) and the resulting Peak Particle Velocity (PPV) will assess any potential structural damage in the area as a result of construction work and ensure strict adherence to government regulations. Throughout the MRT project, 01dB has also been working closely with the Institute of Noise and Vibration at the Universiti Teknologi Malaysia Kuala Lumpur (INV). Under the ECOTECH leadership Managing of Professor Director, Ir Nicholas Dr M Salman Dal Sasso Leong, (pictured one of South right) was East part Asia’s of an foremost expert team experts of engineers on the environmental and researchers impact investigating of noise the and effect vibration, of a non-explosive guidelines methane were established gas on mixture what on type various of instruments ultra-wide should band channel be employed coefficients. and how to use them for the construction process. Using simplified apparatus and a Vector Network Analyser, the research espoused that a simple sensor could detect the accumulation of methane gas in an environment well before it becomes explosive at around a concentration of 5%. The study suggests that this technique could be used to determine the presence of non-explosive levels of methane for situations where methane builds up gradually in a confined or enclosed area in industrial mining activities. As a result of the investigation, Nicholas and the international team* wrote a paper titled, “Ultra wideband channel coefficient measurements for detecting methane gas in a multipath environment” which was published in the prestigious Australian Journal of Electrical and Electronics Engineering (Volume 13, 2016 – Issue 3) and online at http://bit.ly/2znJnYJ (Continues on page 12) “ With both and ORIO in place o the MRT L 2 project, have the a to deliver consisten accurate monitorin for noise vibration ecotec Ho Chi Min City, Vietnam
LOS ANGELES, USA Setting the reference quality benchmark for small sensor technologies American ECOTECH has developed a world-first Small Sensor Environmental Test Chamber that relies on reference quality ECOTECH Serinus ® gas analysers (SO 2 , O 3 , CO, H 2 O and NO) to accurately mimic global ambient environmental conditions. With the growing number of low cost, near-reference and/or small sensors entering the marketing, the South Coast Air Quality Management District (SCAQMD) in Southern California was looking for a cost-effective, reliable and fast-track way to test small sensors under a variety of different environmental conditions. BANGKOK, THAILAND Ensuring construction compliance with environmental regulations Noise can often be the first sign of danger, especially in the context of huge construction projects. 01dB’s ORION and DUO smart vibration monitor and sound level meters have a proven track record in the development of multiple high-rise projects in the downtown Bangkok area. The Pollution Control Department (PCD) has relied on 01dB to perform on-site monitoring for the duration of pilling works to measure PCPV and resultant PPV for assessing structural damage and potential vibration impact on neighbouring residential buildings in line with Thailand’s DIN4150 & 5669 standards. SYDNEY, AUSTRALIA Monitoring air quality on Australia’s biggest infrastructure project Once completed, Sydney’s massive WestConnex and NorthConnex motorways will revolutionise the way Sydney’s road and transport networks operate, including the construction of the country’s two longest tunnels. Tailored air quality tunnel monitoring solutions engineered by ECOTECH help monitor the air quality and safety of workers, drivers, passengers and the community before, during and long after tunnel construction is completed. ECOTECH is designing, manufacturing, installing and commissioning dozens of Serinus ® equipped complete ambient stations, 50+ air quality sensors, 100+ air velocity sensors and at least 5 ventilation outlets (CEMS) for this major tunnel construction project. acoemgroup.com | 5
