common practice.

- Cable termination workmanship to be done to highest standard.

- All wires are to be ferruled and crimped using correct colour coded ferrule size suitable to wiregauge

- All wires to be tagged and labelled to match the labels of the terminal ID they are to beterminated into.

- 3x core cable to be stripped as close to wire ends as possible to ensure maximum length ofcable for protection stripped back wires to be as short as possible.

- Individual wires from a multi core cable at strip end to be covered with heat shrink material orrapped with self amalgamating tape.

- All cables to be tagged with tag number clearly visible close to the termination point.

- Earth and Ground wire termination ends to be greased with special Dielectric Grease toprevent moisture and corrosion.

- Describe the different type of cable segregation and transiting via the existing cable transitmatrix blocks.

- Cable transit block to be sealed from outside of the SCADA/Telecom buried container withwater resistant silicon or protective material against water table ingress and dampness.

- Due care and attention is required during PIDS Fibre Optic Cable splicing and termination intoexisting ODF. Live Telecommunication fibre cores are present in same ODF.

- Recommend all splicing works and OTDR testing to be done by BIL specialist and certifiedTelecommunication engineers or strictly supervised by BIL engineers.

13- Section 4.0:- Document formatting: No requirement to sub section number each paragraph. Maintain

- Add note to test continuity and correct termination and RJ45 connection to Cat7 data and videocables using LAN tester and Cat7 cable certifier/printer device.

- Add note to test continuity and correct termination and splicing of the perimeter intruderdetection FOC using OTDR.

- Add a note to record all cable inspection, continuity and meggering tests onto relevant EE1 andEE12 GOC Certifications.





- Environmental impact mitigations (topsoil management, housekeeping, waste management,reinstatement, etc.) will be handled in line with BTC Statement of Environmental & SocialRequirements (BTC-SOR-ESM-GEN-001).

- All wastes, except for inert wastes, will be transferred to the nearest PT segregated, labelled,packed and with properly filled and signed Waste transfer Notes generated by BIL.

- Inert material originating from construction activities are subject to reusing / recycling. Shouldvillagers and/or local authorities are willing to take those materials, written consent/approvalfrom villager/mukhtar/local authority (whichever is applicable) will be signed to receivematerials for reuse and collect pre-handover photographs of the site. If not, approvedquarry/landfill will be used as an option. No quarry or landfill will be used without approval fromBTC Co. Written consent/permit for disposal and sign-off document (confirming that there areno residual issues and no complaint) should be obtained from the quarry/landfill owner orlicensed operator and photographic evidence on the pre, during and post disposal status of thedisposal site will be collected.

- All generated wastes should be segregated, classified, labelled and stored as follows: Inert;Non-hazardous Recyclables (glass, metals, paper/cardboard), Non-hazardous Reusables (e.g.

vegetation, wood and food scraps) and non-hazardous; Domestic (non-hazardous waste thatcannot be recycled nor reused); Hazardous - non-medical; Hazardous - Medical.

- Each hazardous waste will be separated from each other and will not be mixed under anycircumstances. Hazardous wastes shall be stored in a bunded (designed to contain 110% ofvolume of the largest container, drum, etc), impermeable, covered and access restrictedstorage area.

- Topsoil management requirements/rules should be followed carefully. Currently availableaccess roads will be used to reach the working area. However, if vehicle movement outside ofthe fence and the access road becomes essential, the compacted area compacted topsoil byheavy vehicles shall be ploughed by a hydraulic tractor with ripper in order to help therehabilitation of the topsoil after construction work is completed. If the level of compaction is

significant and the impacted vegetation may not recover as a result of this compaction,reinstatements methods such as seeding, fertilising and jute matting shall be used to mitigate

the impact. Where excavation is required as per the work, the topsoil shall be carefully stripped

to its full depth and stored separately. If excavation is NOT an issue, compacted topsoil byheavy vehicles shall be ploughed by a hydraulic tractor with ripper in order to help therehabilitation of the topsoil after construction work is completed. The BTC RoW and any extraland used shall be reinstated to a sufficient extent in order to allow the affected area to bereturned to its pre-project use and productivity. In all cases BTC-SOR-ESM-GEN-001 shall befollowed.

- Wastewater will be sent to the nearest PT accompanied with a BIL Waste Transfer Form.

- Seasonal sensitivities:

BVT25:

- The area is in the Ecologically Sensitive Area 21 (ESA21). There is also seasonal constraint forbreeding mammals (wild goat) between October-December and for bears hibernation inNovember-April. There are also constraints for breeding birds: for Turkish Chamois in March-April and October-December and for Forest Durmouse in May-September.

- However, since the construction works will be executed within BVT fence area and in thevicinity of BVT, the precaution will be as follows:

- Worker training regarding non-disturbance of nearby herds should be carried out.

- If project execution extends to March or beyond, environmental team shall be notified and themitigation measures will be advised by environment team if required accordingly.

BVT 27 & BVT 28:

- The areas are in the Ecologically Sensitive Area 24 (ESA24). There is also seasonal constraintfor breeding birds (Black kite) from April with July remaining sensitive for late and secondbroods. However, since the construction works will be executed in October-December withinBVT fence area and in the vicinity of BVT, the only precaution will be as follows:

- If project execution extends to April or beyond, environmental team shall be notified and themitigation measures will be advised by environment team if required accordingly.

16- Section 8.0:

- Recommend notifying BIL and request to put an ICSS Inhibit signal on, prior to power cabletermination into existing Electrical Power Distribution Cabinets and Splicing of PIDS FOC intoexisting ODF at BVTs.

- Recommend discussing RA with relevant BIL personnel to protect and safeguard against anyshort circuit which may lead to loss of power and potential shutdown.

- Recommend discussing RA with BIL Chief ICSS & Telecoms engineer for awareness.

17- BIL Lifting Plan for Routine works document BIL-FRM-HSE-GEN-116 should be filled during permitapplication of pre-cast foundation installation

18- Lifting plan / sketch for camera pole precast foundation should be prepared and attached.
