HDD
Services Feasibility Studies
HDD is often contemplated to avoid sensitive
areas, but are the soils amenable, will
the profile fit your hopes, and is HDD
cost competitive? Harisons will review
the site and available background materials
to produce a preliminary design and cost
estimate. HDD can also be compared to
alternate methods of construction.
Site
Survey & Geotechnical Analysis
Harisons can work with local firms for
detailed route surveys and identification
of underground utilities. An appropriate
geotechnical investigation / bore holes
as required can be coordinated with local
contractors
Design
or Design Review
Once all information is available, Harisons
can provide detailed design of the alignment
and profile. Designs are based on optimum
constructability and minimal environmental
impact. On the basis of calculated construction
stresses Pipe specifications can be selected
or visa versa.
Contractor Selection
Harisons will provide detailed specifications
for construction and materials which is
part of the tender package. Prequalification
of bidders and client representation throughout
the tender process can also be provided.
Construction Monitoring
Harisons can follow the project into the
field by providing specialized monitoring
of HDD activities. As part of the Quality
process, progress reports and review of
coeval construction records will ensure
that the work is in compliance with the
specifications and permits.
