Construction Impacts on a Healthcare Facility - Issues
John Alberico, Rowan Williams

Building construction can have an enormous direct
and indirect impact on the local environment, especially on existing
facilities adjacent to the construction site. Fugitive dust from
construction activities and vehicle emissions can infiltrate into
existing buildings, resulting in poor indoor air quality that may
be a nuisance or more seriously threaten the health of workers and
occupants, and compromise experiments. The importance of dust on
air quality has been recognized by LEED, which requires a dust control
plan for LEED-NC certification.
Noise and vibration impacts are also associated with construction
activities. High levels of noise or vibration may reduce the comfort
of occupants, disrupt the operation and performance of vibration
sensitive procedures (e.g. production, research, imaging), and damage
vibration-sensitive equipment in nearby laboratory buildings.
Attention to these environmental impacts during construction leads
to a safer and more comfortable environment for these workers and
occupants. This poster will outline in detail the environmental
issues relating to construction activities, namely: fugitive dust,
diesel odors from heavy equipment, environmental noise, and vibration.
Also presented will be typical mitigative strategies for minimizing
the environmental impacts at laboratories located adjacent or close
to construction activities.
The major lessons learned from this poster will be:
- Identify several different environmental impacts that may occur
at existing laboratories due to construction activities occurring
- Outline different methodologies used to quantify environmental
impacts and develop mitigative strategies.
- Present typical mitigative measures used to minimize the impact
of construction activities on existing laboratories.
is a project director specializing in air quality assessments. He
joined Rowan Williams Davies & Irwin, Inc. (RWDI) in 1988, and
became a principal in 2004. As a project director, he provides overall
technical direction to engineering teams on air quality and emission
inventory projects ensuring that a high level of service is provided
and RWDI’s interests are preserved on all projects.
John’s area of technical expertise is in exhaust and dust
dispersion, which has included involvement in several hundred projects
providing expert consultation, and conducting both numerical and
wind tunnel modeling. His primary focus has been in the healthcare,
higher education, and pharmaceutical sectors. His involvement in
many of these projects has included environmental impact assessments
and certificates of approval.
John has also managed engineering teams that have provided air
quality, odour, dust, ventilation, noise, acoustic, and vibration
assessments for a broad range of applications on local, national
and international projects. These have included pits and quarries,
landfills, composting facilities, roadways, residential developments,
and industrial facilities in addition to healthcare, higher education,
and pharmaceutical facilities.
