Cable design and crossing study
A draft cable design and crossing study, with worksheets for the calculations HVCO supports.
e.g. a draft study for a sample route lists its crossings and calculations.

Route options appraisal
Routes compared on the checks you declare and on cost; the cheapest option that passes is flagged.
e.g. four route options compared; the cheapest option that passes the checks is flagged.

Trench design and cross-sections
Cross-sections and 3D views of the trench, from the dimensions you record.
e.g. a cross-section shows two circuits in one trench, labelled with your dimensions.

Network area, proposed from your route
Proposes the network area from your route’s first point, using approximate NESO boundaries. You confirm it, and the source is shown.
e.g. a route starting in the north of England gets a network area to confirm.

Minimum cover check
Cable cover checked against minimums taken from operator documents, where the land use and voltage are recorded.
e.g. a cable under a verge is checked against a minimum cover figure.

Cable sizing checks
Design current, voltage drop, losses and short-circuit checks, with the inputs and the working shown.
e.g. a 400 m circuit is checked for voltage drop and losses.

Construction pack
A draft pack: cable, cut, drum and joint schedules, with a pulling plan and traffic proposal for review.
e.g. a pack lists each cable cut and drum, with a pulling plan for review.

Commissioning, as-built and handover records
A commissioning checklist, as-built records and a handover pack, compared with a tolerance you set.
e.g. installed length is compared with design, using the tolerance you set.
