1. SCOPE

As defined within the Form B the proposed development of Building S1, at King’s Cross Central,

has the potential to cause movement of the two Thameslink Canal Tunnels. For this reason it is

be necessary to carry out condition surveys before, once during construction (following piling)

and after the development is complete.

The location of Building S1 in relation to the tunnels is presented within Appendix 2.

The condition surveys will be undertaken in a 100m section of the northbound and southbound

tunnels below the S1 site. This is the maximum length covered by the calculated zone of

influence of the development proposal. The condition survey will be a walkthrough visual, non-

intrusive inspection of the tunnel, generally noting any defects and notable features and it is

expected that each survey can be completed in a single night shift with a minimum of 4no

personnel.

The location of the survey shall be related to the length of tunnel which has rail monitoring

installed by TPS. It is expected that chainage or tablet markers will not be available in all the

tunnels. This will be double checked within the tunnel by using a measuring wheel and chalk will

be used to mark out temporary markers at intervals along the sidewalls.

2. METHODOLOGY

2.1 Pre-Works Condition Survey

The Pre-works Condition Survey will be a visual, non-intrusive inspection, providing a detailed

record of the condition of the tunnel at the time of inspection. Subject to the time available within

the tunnels, this will also include a 360 degree photographic survey. The personnel shall carry

out the work on foot bearing cameras and notepads. The 360 degree GoPro camera will be

mounted on a tripod of an approximate 2.5 meter height. Each significant defect will be noted,

measured where possible, photographed and referenced on survey sheets. The survey will be

concerned with the condition of the following:

The structural concrete segments forming the tunnel structure

The interfaces between the concrete segments

Any potential water ingress

A visual examination of defects will be carried out for all accessible areas. Inspection of the

tunnel arches and soffit will be carried out on foot as no high level access is to be provided. An

appropriate source of lighting will be carried by the personnel.

2.2 Condition Survey during construction works

The Condition Survey during the construction works will be carried out in the same manner as

the Pre-works Condition Survey described in Section 2.1. This survey shall provide a detailed

2


record of the condition of the tunnel following the piling works. It shall identify all defects and

shall highlight any alteration to the condition of the tunnel as described by the Pre-Condition

Survey.

2.3 Post-Condition Survey

The Post-Condition Survey will also be carried out in the same manner as the Pre-Condition

Survey described in Section 2.1. This survey shall provide a detailed record of the condition of

the tunnel following the construction works. It shall identify all defects and shall highlight any

alteration to the condition of the tunnel as described by the Pre-Condition Survey.

APPENDIX 1

NETWORK RAIL– CANAL TUNNELS SECURITY AND ACCESS

INFORMATION PACK

Canal Tunnels Information Pack –Security and Access Rev 6.1

Information Pack – Security and Access Arrangements at Canal Tunnels

Thameslink (Network Rail) Information Pack

1. Canal Tunnels Summary of Current Arrangements:

o All systems are commissioned and live but the Canal Tunnels are not operational or entered

into service, the points are clipped at either end and the routes are not signed over to the

signaller.

o The Overhead Line is live (25000Kv) and should always be treated as such; there are only

limited scenarios when access into the tunnel is permitted without an isolation being

granted (access arrangements with regards the overhead line further detailed within section

2).

o The connecting junctions from Canal Tunnels onto the Midland Mainline and the East

Coast Mainline are live railway infrastructure (Refer to section 3 and Appendix B for more

details). These lines cannot be accessed without the required safe system of work in place.

o There is no Principle contractor managing the site on a daily basis, The Network Rail project

team, ODM team and H&S team manage the access to this site (details within section 2

access arrangements).

o The track circuits are not strapped out throughout the tunnels therefore no machines or

trolleys can be brought into the tunnels unless under a possession environment as it will

drop track circuits on the live railway.


2. Access Arrangements

Walkouts:

To undertake walkouts in the tunnel the following process shall be followed:

o Project manager Gareth Owen ([email protected]) and Senior ODM Manager

Mick Hilder ([email protected]) shall be informed of the walkout 1 week

before, detailing the date, time, timeframe and site contact for the walkout.

o A Work Activity Risk Assessment shall be produced based on the template in appendix A,

taking into consideration the Network Rail lifesaving rules and the Canal Tunnels site specific

health and safety considerations in section 3. This WARA needs to be sent to Gareth Owen

prior to the walkout ([email protected]).

o The walkout must only be undertaken in the tunnel 4ft or squeeze way and not on the

emergency walkway. If the walkout is required to be undertaken on the emergency walkway

then an isolation of the tunnels needs to be planned as per the normal isolation request

period and within the required timescales.

o The Duty ODM must be called before the party enters the tunnels and after they leave the

tunnels. The weekly ODM roster can be requested from Gareth Owen

([email protected]) or Mick Hilder ([email protected]).

o The attendees of the walkout must have the WARA briefed to them before accessing the

tunnels.

o No Materials or track trolleys can be brought in as part of a walkout; the walkout can only

constitute a visual low level inspection.

o No lone working is permitted within the tunnels; the minimum group size is two.

o No SSOWP is mandated to access the tunnels for a walkout (provided no isolation is

required), the access is fenced and segregated from the Midland Mainline end and all parties

can stay 10m away from the live railway on the ECML end by not going beyond the RRAP.

More details of this can be found in section 4 and Appendix B.






Physical Works:

To undertake physical works within the tunnels the following process shall be followed:

o Project manager Gareth Owen ([email protected]) and Senior ODM Manager

Mick Hilder ([email protected]) shall be informed of the works 1 week before,

detailing the scope of works, date, time, timeframe and site supervisor for the works.

o The contractor shall amend their WPP and TB to reflect the site specific health and safety

considerations in section 3. This needs to be signed off by the relevant parties and a for

information copy forwarded to Gareth Owen ([email protected])

o An isolation is required to undertake any works within the tunnels.

o A SSOWP is required to undertake any works within the tunnels.

o The Duty ODM must be called before the party enters the tunnels and after they leave the

tunnels. The weekly ODM roster can be requested from Gareth Owen

([email protected]) or Mick Hilder ([email protected]).

o No track trolleys or Machines can be brought in as part of the work unless it is in conjunction

with a possession the East Coast Mainline/Midland Mainline.

o No lone working is permitted within the tunnels the minimum group size is two.

o The contractor becomes principle contractor of the tunnel they work in for the duration they

are working in it.






3. Health and Safety considerations for all parties who need to access Canal Tunnels:

The list below details risks to consider when entering Canal Tunnels (this is not exhaustive and you

should always undertake a thorough task based and site based risk assessment when planning your

works).

Live overhead line (25000v) or OLE – no work can be undertaken without an Isolation and C

form, walkouts can be conducted within the 4ft or Squeezeway but not on the walkway.

Please ensure you also follow the Network Rail lifesaving rules:


4. Entering and Exiting the Canal Tunnels

o There are four permitted access points into the Canal Tunnels (diagram in Appendix B):

1. Off St Pancras Low Level Platform A, following the segregated walkway into the Up Canal

Tunnels.

2. Off St Pancras Low Level Platform B, Following the segregated walkway into the Down

Canal Tunnels

3. Via the pedestrian access point off York Way (Standard East Coast Mainline Locks on the

access gate).

4. Via the vehicle access point off York Way and through Argent land (Standard East Coast

Mainline Locks on the access gate).

o The emergency lighting can be switched on manually with the emergency light switches located

at walkways on each entrance of each tunnel bore and located every 200m within the tunnel.

Access is permitted on the walkway to switch the lights on. The lights are on a 45 minute timer,

after 45 minutes half the lights turn off and after a further 15minutes the rest of the lights turn

off. To reset the timer just re-press one of the emergency light switches. Example of switch

below.

o Remember to contact the duty ODM before you enter the tunnels and once you leave the

tunnels.


5. Security and Emergency and On Call Information
