Case Studies
Branksome Hall
At Branksome Hall in downtown Toronto, what started as a simple mapping
exercise turned into a mystery hunt as more services and discrepancies
from construction documents were found.
Terra Discovery found two obstructions in sewer pipes, two additional
sanitary sewers to those shown on drawings, two gas services not on
drawings and additional clean outs covered over and not shown on drawings.
Most importantly a sewer main which was documented as 14" diameter,
was in fact only 4" diameter and would not have accommodated the
planned renovations. This was discovered before construction started
allowing the design to be changed and saving valuable time as well as
avoiding expensive extras.
Royal Ontario Museum
Terra Discovery was contracted to join the team renovating and building
a new addition to the Royal Ontario Museum.
The work at the ROM was complicated by previous additions and renovations
which have occurred since 1910 creating in a crowded and constrained
utility environment.
A further complication was that the Museum had to be kept open during
construction of the new addition.
Terra Discovery helped achieve a minimum impact on the site and surrounding
area through the use of GPR and EM Tracing to locate underground services
The Site Superintendent for the project praised Terra Discovery for
the "speed and diversity" of the mapping services and technologies
used to map the existing underground utilities. The efficiency with
Terra Discovery completed the mapping of the site allowed the demolition
required to proceed with minimal disruption and without damaging existing
services which allowed the Museum to continue operating during the demolition
and construction.
Other Terra Discovery Projects/Sites/Clients include:
- York University
- Upper Canada College
- Georgian Mall
- Durham College
- Guelph University
