1 Introduction

1.1.1 This document provides details of the programme of archaeological investigation required to mitigate the impact of construction of the Liverpool Street utilities corridor and other 0503 works on archaeological deposits. It is an addendum to the Written Scheme of Investigation for Liverpool Street Station (0138-MMD-T1-RST-C101-00001) and should be read in conjunction with that document.

1.1.2 The archaeological mitigation works relating to 0503 activities (comprising the construction of the utilities corridor, the sewer shafts: MHS1 (west) and MHS2 (east), 100 Liverpool Street diversion and Phase 3 utilities diversions) set out in this document supersede those in the previous WS! addendum (C138-MMD-T1-RST-C101-00004).

1.1.3 This document outlines the requirements for the Principal Contractor (0503) that will be undertaking civils works on the site in liaison with the Crossrail Project Archaeologist and the 0257 Archaeology Contractor (Museum of London Archaeology - MoLA).

2 Scope of Works

2.1 Aims and objectives of the investigation

2.1.1 The aim of archaeological mitigation is to preserve by record surviving archaeological deposits to be affected by 0503 activities (comprising the construction of the utilities corridor, the sewer shafts: MHS1 (west) and MHS2 (east), 100 Liverpool Street diversion and Phase 3 utilities diversions). The two key phases of archaeology positively identified in Crossrail evaluation (XSM10) relate to the Roman period and post-medieval burials from the Bedlam burial ground.

2.1.2 Mitigation will be achieved through a programme of archaeological investigation to be conducted by the 0257 Archaeology Contractor in liaison with the 0503 Principal Contractor in accordance with the Site-Specific Written Scheme of Investigation for Liverpool Street (C138-MMD-T1-RST-C101-00001) and the Crossrail Generic WS! (CR-XRL-T1-GST-CR001-00003) and the standards listed therein.

2.1.3 A summary of the archaeological work carried out to date and the scope of further work is set out in Table 1 below:

2.2 Summary of results from Crossrail archaeology works

2.2.1 A general watching brief on an exploratory test pit in the Railway Tavern to determine the location of a coal cellar in advance of pile design, determined that all archaeology at that location was truncated by the construction of the building in the 1870s.

2.2.2 Evaluation trial trenches 1, 1A and 2 were located partially within the northern pile line of the utilities corridor. Trial trenches 1 and 2 were excavated to the base of archaeological deposits and 1A was stopped at approximately 1.5m below ground level due to the high concentration of services restricting access.

2.2.3 Evaluation trial trench 1A exposed 20th century utilities that had truncated burials along the length of Liverpool Street within the pile line and northern part of the utilities corridor. These utilities were located adjacent to the backfilled cellars of former buildings at 1-14 Liverpool Street. Consequently the likelihood of encountering in situ burials during the excavation of the utilities corridor is very low. However, disarticulated human bone may be present in the made ground.

2.2.4 A series of pits were also excavated along the length of the 1250mm pile line to approximately 109.5mATD to remove human remains. Refer to Appendix A, Drawing 1 for the location of previous investigations.

2.2.5 An area of higher archaeological survival 600mm wide is present intermittently along the northern edge of the corridor from approximately 109.3m ATD — c. 107.8mATD, refer to Figure 1 and Drawing 2 — Appendix A.

2.2.6 Roman archaeological deposits are predicted from 107.8m ATD down to 107m ATD along the length of the corridor. Deposits deepen (to approximately 106mATD) in the western 15m of the utilities corridor towards the course of the former River Walbrook.

2.2.7 Evaluation trial trench 5 and pile line pit 1 both encountered the backfilled remains of a 20th century below ground lavatory to 108.17mATD. Roman archaeology may survive in pockets beneath the lavatory, but a tunnelled sewer that also passes beneath it has removed large areas of Roman deposits across the length of the site. The extent of the lavatory is uncertain, however, all archaeological remains in its footprint have been removed to 107.17mATD.

2.2.8 Exploratory test pits to identify existing utilities were excavated at the planned locations of the MHS1 and MHS2 at either end of the utilities corridor. At the western end (MHS1) excavation to a depth of 1.2m below ground level showed total truncation of archaeology to that depth by existing utilities. The made ground contained disarticulated human bone, inferring that the burial ground continues beyond the western edge of the Broadgate Station Ticket Hall. The test pit in the planned location of MHS2 (the eastern end) was also excavated to 1.2m below ground level, and no archaeological deposits were encountered. Additionally no disarticulated human bone was identified, which confirms that the boundary of the burial ground lies further west than MHS2.

2.2.9 The western extent of the utilities corridor and MHS1 are located in proximity to the former Walbrook channel. As such, the depth of alluvial deposits in the western end of the worksite is expected to be down to approximately 106mATD.

2.2.10In the footprint of the Broadgate ticket hall human burials survive across the majority of the site beneath a significant number of utilities. Burials are present between 111.52mATD and 109.45mATD but the upper level of the burials varies across the site.

4.3 Documentation and management

4.3.1 0503 will organise weekly progress meetings at 1-14 Liverpool Street throughout the duration of the archaeological works. The meetings will discuss safety, progress against programme and any other matters arising in relation to the archaeological works. Attendance is required from 0503, the groundworks contractor, 0257, a representative of the Crossrail site team and a representative of the Crossrail archaeology team.

4.3.2 Upon completion of the archaeological excavation the 0257 Archaeology Contractor will issue a signed completion form countersigned by the Employers Archaeologist to 0503.

4.4 C503 Procedure for detailed archaeological excavation

4.4.1 Refer to 0257 Method Statement (C257-MLA-X-GMS-C101-50001) for the detailed excavation methodology.

4.4.2 Use of excavators or other plant within the area shown on drawing C138-MMD-C-DDA-C101 Z-89001 (Drawing 3 - Appendix A) shall only be undertaken with the agreement and under the observation of the 0257 Archaeology Contractor.

Utilities corridor (Appendix A — Drawing 3: C138-MMD-C-DDA-C101_Z-89001)

4.4.3 Refer to 0257 deposit sketch (Drawing 2 - Appendix A) for locations of the phases used in the following sequence.

4.4.4 0503 will allow for up to 10 No. archaeologists to be on site during detailed excavation.

4.4.5 The following sequence for archaeological excavation has been agreed with 0257 and is the result of a series of meetings between Crossrail, 0503 and their sub-contractors, and 0257:

Phase 1

4.4.6 0503 excavate modern material down to construction level for 1st props (109.2mATD), under general watching brief by 0257 to record the predicted upper 100mm of archaeological deposits against the northern side of the corridor.

4.4.7 If disarticulated human remains are identified in the made ground they will be removed by the 0257 Archaeology Contractor and 0503 will store them securely on site and provide them to the Exhumation Contractor in accordance with the Ministry of Justice burial license.

Phase 2

4.4.8 0503 insert first level of props at approximately 109.2mATD.

Phase 3

of 21


Crossrail Limited


1Crossrail

4.4.1 Where archaeological deposits have been truncated, 0503 will excavate the modern material under 0257 supervision using a smooth-edged ditching bucket down to a maximum of depth of 107.8mATD. Please note that the surface of archaeological deposits survives at different levels. The attending 0257 archaeologist will supervise the machining process during this phase.

Phase 4

4.4.2 Where archaeological deposits have not been truncated, 0257 will hand excavate and record down to a depth of approximately 107.8mATD.

4.4.3 Phases 3 and 4 will be conducted as a rolling programme of targeted watching brief along the corridor, with a safe demarcated distance between machine operations and areas for archaeological work.

Phase 5

4.4.4 0503 machine and/or hand excavate (as appropriate) any remaining modern material to approximately 107.8mATD under archaeological supervision.

Phase 6

4.4.5 0503 Insert second level of props at 107.8mATD.

4.4.6 The insertion of the second level of props creates a series of twelve/thirteen 3.2m x 2m areas along the length of the utilities corridor. These areas will be hand excavated by 0257 in two stages (Figure 2): Stage 1: areas 1, 3, 4, 6, 7, 9, 10 and 12; Stage 2:2, 5, 8 and 11. During Stage 1 the Stage 2 areas will be used for spoil removal and vice versa in Stage 2.

4.4.7 The following phases (7 to 9) set out the 0257 excavation process within each 3.2m x 2m area. These phases will be facilitated by 0503:

Phase 7

4.4.8 0503 facilitate the 0257 excavation and recording of Roman archaeological deposits.

Phase 8

4.4.9 0503 facilitate the 0257 excavation and recording of the northern half of the Roman archaeological deposits, to produce a composite East—West section.

Phase 9

4.4.100503 facilitate the 0257 excavation and recording of the northern half of the alluvial deposits, continuing the composite East—West section. Where the section is more than c. 1.2m deep or is unstable, it will be carried out in 2+ stages (and/or hand augered).

4.4.11 If Roman structures/features are identified in the alluvial deposits which continue into the unexcavated half, these will be locally excavated by 0257.

• waterproof;

• translucent (to provide sufficient light); and

• be of a type that can be quickly erected and removed to facilitate access for plant when required.

4.4.4 Ground level (112.76m to 112.28m ATD) to surface of burial ground (111.52m to 110.70m ATD)

4.4.5 Remove, under supervision of the 0257 Archaeology Contractor the road surface and modern overburden, to the predicted level of cemetery deposits. The surface of cemetery deposits is present at an average depth of 1.34m below ground level (highest level identified in trial trench evaluation: 111.52mATD).

4.4.6 If disarticulated human remains are identified in the made ground they will be removed by the C257 Archaeology Contractor and C503 will store them securely on site and provide them to the Exhumation Contractor in accordance with the burial license.

4.4.7 The burial ground (from c.111.52m to 109.45m ATD)

4.4.8 C503 will facilitate the excavation of the burial ground (present from approximately 111.52m to 109.45m ATD) by the C257 Archaeology Contractor.

4.4.9 Deeper archaeological deposits (c.110.64m ATD to 105.00m ATD)

4.4.10Following the removal of cemetery deposits by the C257 Archaeology Contractor, C503 will facilitate the further excavation of archaeological deposits by the C257 Archaeology Contractor until the full sequence of deposits has been excavated. Due to the location of these works on the conjectured route of the River Wa!brook the base of archaeological deposits may be as deep as 106-105mATD.

4.4.11Upon completion of the archaeological excavation, and when the completion certificate has been signed off, bulk excavation by C503 may commence.

4.5 C503 Procedure for archaeological general watching brief and targeted watching brief

4.5.1 The removal of made ground by C503 will be carried out under archaeological observation (general watching brief) by the C257 Archaeology Contractor.

4.5.2 The C257 Archaeology Contractor will advise C503 if and when archaeological deposits are encountered. C503 will allow for archaeological deposits to be hand excavated/machined (as appropriate) in stages (targeted watching brief) by the C257 Archaeology Contractor to the maximum depth of impact (It is estimated that the trigger point will be at approximately 1.3-1.5m below ground level). NB. Human remains are likely to be encountered.

4.5.3 Where the construction methodology involves timber-headed tunnelling, C503 will allow access for the C257 Archaeology Contractor to record archaeological deposits in section where possible.

4.5.4 Material excavated by C503, which contains disarticulated human remains will be stored securely on site by C503 and provided to the Exhumation Contractor in accordance with the Ministry of Justice Burial License.
