DND
Unexploded Ordnance (UXO) Legacy Site Program Remediation
Project Risk and Management Planning
The DND UXO and Legacy Sites Program, created in 2005, works
to reduce safety risks posed by unexploded explosive ordnance
(UXO) at all "legacy sites" across Canada. A legacy site is
any property not owned by DND that contains UXO, regardless of
the origin of the UXO. NOTRA was contracted to develop an
overall Survey Work Plan (SWP) and conduct UXO project risk
assessments and develop associated project management plans
for:
-
Tsuu
T’Ina Nation (TTN) Sarcee Reserve Chiila Estate sub-division
construction program; and
-
Two (2) Sub-Division construction projects within the
Vernon legacy area.
The
objective of the SWP plan was to develop a master project work
plan that would be used as a generic operational oversight for
UXO related activities; namely, UXO avoidance, UXO surface
clearance, UXO subsurface clearance, UXO survey/investigation,
and UXO expert advise. The master work plan was developed in
accordance with the DND Work Plan Guidance Document for EO
Investigation and Clearance Operations and based on the
NOTRA’s Standard Operating Procedures (SOPs).
For the
TTN and Vernon Legacy Sites, NOTRA conducted a UXO impact
analysis and subsequently prepared associated project
management planning documentation including:
-
A UXO
remediation work plan addressing all site specific work
procedures including UXO Surface Clearance, UXO Avoidance,
Geophysical Survey, and Intrusive Investigation;
-
A cost
breakdown;
-
A
responsibility assignment matrix (RAM);
-
Work
Breakdown Structure (WBS);
-
A detail
schedule (Gantt format); and
-
Project
organization plan
Phase I:
UXO impact analysis consisting of a site visit and information
gathering session with Construction Engineering
representatives. NOTRA collected information on construction
and intrusive activities scheduled to occur within the
boundaries of affected risk areas. Based on the information
collected, NOTRA conducted an options analysis.
Phase II:
NOTRA’s plans focused on UXO avoidance options. UXO avoidance
efforts included conducting a surface clearance of the work
area (completed prior to any drilling activities), a
geophysical survey intrusive investigation (mag and dig) of
any anomalies (completed prior to any drilling activities),
and UXO-based supervision during drilling activities and
subsequent digging activities.
