The second event is coming!

Date: Monday, May 2
Time: 18:00 – 19:30 (PT)
Cost: Free!
Online

Together we will go through two BCIT graduate students’ research projects focused on acoustic problems. First, M Kibria Shah will present the Analysis of Construction Site Noise from the Community Perspective. Second, Jessica Carolina will discuss Investigating Potential Acoustic Indicators for Sound Quality Standard of Ecocity Frameworks.

Our special guest is Asal Souri, Project Manager at BC BUILDING SCIENCE LTD.
Asal will review a couple of renovation projects she has managed, explaining the entire process along with some of the challenges we had to deal with along the way.

Please read the information below to better prepare for the presentation and know the presenters more closely.

M Kibria Shah

Bio:
Kibria is an occupational safety and health (OSH) professional by training. He holds a MASc in Building Science from the British Columbia Institute of Technology, and a BTech Mechanical Engineering from the National University of Singapore. He is a current holder of the Canadian Registered Safety Professional (CRSP) designation among other industry-recognized recognitions.
With over 9 years of experience in OSH consulting, Kibria has both field and management experience in various industries including construction, buildings and infrastructure, and the shipbuilding/repairing sector in Canada and Singapore.
His current research in BCIT includes investigating the impact of construction noise through the lens of public health and urban planning, application of sound quality, and psychoacoustics in the built environment settings.

Presentation description:
The overall research investigated intrusive noise levels from construction sites in residential communities which may be detrimental to health. This research used the drone imagery of an actual construction project to identify noise sources from the construction site and CadnaA acoustic software to predict the noise propagation from construction sites in three modeled residential communities.
Construction noise propagation and community annoyance were modeled for single-family, multifamily, and high-rise residential neighborhoods where noise levels exceeded the recommendations of the World Health Organization and Health Canada Guidelines. When construction works continue without any noise mitigation measures, one-fourth of residents would have been overexposed according to the City of Vancouver (CoV) guidelines. Several noise control strategies were applied and findings indicated that a combination of noise controls was more effective than a single control measure.
When noise mitigations were in place, the City of Vancouver noise by-laws were found to be attainable, and no residents would have been overexposed to construction noise. However, when applying the Health Canada guidelines, which are more stringent than municipality noise by-laws, it was predicted that more than one-third of residents would be overexposed and would experience widespread annoyance with or without mitigation strategies.
The understanding of construction noise from the community perspective in this research provides a new perspective for the study of construction noise that can help regulatory entities to reduce community exposure to construction noise and it offers solutions for construction noise-mitigating strategies to be incorporated into urban planning and public health policy.

Jessica Carolina

Acoustic Consultant at BKL Consultants Ltd.

Jessica Carolina is a Master of Applied Science of Building Science 2021 graduate. Her concentration was in building acoustics and her research was “Investigating Potential Acoustics Indicators for Sound Quality Standard of Ecocity Framework” with Olympic Village as the site study. Upon her graduation, she decided to continue her career as an acoustic engineer and until now working at BKL Consultants Ltd.

Presentation description:
The sound quality was approved in Ecocity World Summit 2019 to be developed as a bio-geophysical indicator. The classical measures of sound pressure level are not sufficient to quantify healthy noise levels and balanced soundscapes. Additional acoustic indicators relating sound to perception were investigated for potential indicators of Sound Quality including balanced soundscape (normalized difference soundscape index and biophony/anthrophony ratio), psychoacoustical annoyance, temporal sound level variance, and spectra gravity center. The Olympic Village, Vancouver, BC was used as a proxy neighborhood to represent the Ecocity fractal. ISO 12913-1-3: Soundscape standard was applied for collecting and analyzing data. The method of triangulation analyzed acoustic measurements of 38 data measurement locations, 71 survey responses, and taxonomy classification supports the evidence that psychoacoustic annoyance is an appropriate indicator for the Sound Quality benchmark standard in the Ecocity framework.

Asal Souri

Asal Souri, M.Eng., B.Sc., has been working at BC Building Science for 8 years as a project consultant. She received a Bachelor of Science in Civil Engineering from K.N.T University of Technology and a Master of Engineering in Building Science from BCIT.

She has over 10 years of experience in managing building envelope renovation projects including the entire project cycles from the design phase, tendering, and onsite consulting during construction to the closing phase of it.

In addition, she is directing the post-construction services department at BC Building Science. She has several years of experience in conducting post-construction services such as depreciation reports (reserve fund studies), warranty reviews, maintenance manuals as well as conducting building condition assessments of both low-rise and high-rise buildings.

When not at work, Asal is a fulltime mom. She enjoys traveling, hiking, and listening to audiobooks.
