| Trenching, ducts routes & road crossings | All cable, LV, earthing and point-of-connection trenches — excavate, bed, backfill and reinstate — plus the two directional road crossings and site-wide spoil movement. Site fuel carried within the rates. | £194,520 |
| Perimeter fencing & gates | 1.8 m deer fencing (~1,000 m perimeter) and two double security gates. | £37,000 |

Requests for information (RFIs)
The five items below move the price more than any rate — resolving them lets us convert this budget into a firm lump sum.
| Ref | Area | Information requested | Pricing impact |
|---|---|---|---|
| RFI-01 | Foundations | Base details (plan size, depth, reinforcement, founding level) for the transformer, BESS/comms/storage, feeder-pillar and DNO/principal-substation bases. | High — the largest single variable; currently priced provisionally. |
| RFI-02 | Directional drills | Bore length, cover depth and any known services under Motherwell Road for the two road crossings. | Medium — the HDD price is length- and geology-driven. |
| RFI-03 | Spoil / topsoil | Can surplus topsoil and trench arisings be retained and spread on site, or is off-site disposal required? Any WAC / classification? | Medium–High — off-site disposal is a major cost variable. |
| RFI-04 | Ground conditions | Any geotechnical / trial-pit / SI data for the site? | High — rates assume workable ground, no rock, no dewatering. |
| RFI-05 | Welfare / TM | Do AIM civils crews use the site-wide welfare/compound, and who holds traffic management for the road crossings? | Low–Medium. |
Technical queries (TQs)
| Ref | Discipline | Query |
|---|---|---|
| TQ-01 | Earthing | Confirm the 2,620 m earthing trench is dug and backfilled by AIM with the bare copper laid by the electrical contractor — same-day cable pull to avoid double-handling. |
| TQ-02 | Ducting | Confirm duct spec (twinwall / plain) and that duct is supplied under the PVC Duct section only, so the trench rates carry no duct-supply double count. |
| TQ-03 | Access road | Confirm the 350 mm stone-on-geotextile build-up is the agreed spec, with no soft-ground capping / geogrid required. |
| TQ-04 | Fencing | Confirm the perimeter is 1.8 m deer fencing (not security mesh / palisade) — a materially different rate. |
