Comprehensive Survey, Impact Assessment of Historic Features of the
Monuments and Identification of Character Defining Elements In order to provide appropriate mitigation measures for historic
features of the monuments, the relevant comprehensive survey, impact
assessment and protection schedule will be conducted during the detailed
design stage when closer access to all parts of the buildings will be made
possible and when further ground investigations will have been carried
out. Closer access at all levels
inside and outside the buildings will clarify the condition of the fabric and
features and finishes, and the further ground investigations will clarify any
strengthening work required. The design and coordination of the services
requirements and their integration into each building will be carried during
the detailed design stage. The detailed design development of the historic
buildings, with the required interventions, strengthening and integrated
services for new adaptive uses, will be carried out by the conservation
design team and agreed with AMO. For those historical features of significant cultural heritage value
will be defined as the character defining elements of the monuments. All the character defining elements (CDE) will
be well preserved in-situ and repaired in accordance with the work
methodologies approved by the AMO. |

The general mitigation measures to be used during the detailed design
phase will include: · Prior identification and recording of
all the significant features, finishes, fittings, structures, and contents in
the existing buildings, and the site (“historic features”, and assessment of
their heritage significance level for shortlist of the CDE of the monuments · After assessing their existing condition
and vulnerability during construction, a full inventory list of historic
features together with a schedule of protection works for all these
identified items (“protection schedule”) shall be submitted to the AMO for
approval prior to the construction stage. · Preparation of a
detailed precautionary and monitoring measures to preserve or secure
items and finishes remaining in situ during construction. · Preparation of a detailed proposal of
protection measures to the exteriors and interiors of the buildings to be put
in place before the enabling and investigation works during design stage or
before the construction operations. Ensuring the responsible contractor
understands the significance and vulnerabilities of the building structures,
constructions, features and finishes prior to starting the work to avoid
overloading or inappropriate storage or construction activities. |

General Construction Methods Prior to the commencement of the
modification/refurbishment works at an existing building or structure (e.g.
masonry walls near the Old Bailey Wing) , a site survey will be carried out
by the design team, and all building dimensions and levels of the
building/structure shown will be checked and confirmed by the
contractor. Non-percussive piling
methods will be adopted for the construction of the foundation for the new
buildings. Protective and precaution measures to the
existing buildings and structure adjacent to the work area (including the
proposed Grade 3 historic building (No. 20 Hollywood road) and the granite
boundary walls between the Ablutions Block of the police station (building
no. 08) and the General Office of the prison area (building no. 18) which is
adjacent to the new construction of the Old Bailey Wing and for an old
granite walls at Old Bailey Street within 15m from the new construction)
shall be provided to avoid damage to the existing features and to safeguard
the structural integrity during the course of construction. Small scale handheld pneumatic tools with
minimal vibration impact to the existing buildings/ structures are selected
so as to have a better logistic and handling at the existing buildings and
structures, which usually have only narrow working areas. In cases of the
local demolition of structural elements, demountable platforms will be
erected to temporarily support the affected area and divert the loading from
above to avoid instability and create excessive cracking and settlement of
the building/structure. |

Compensatory Tree Planting A new
planting site has been identified for compensatory tree planting in the
Parade Ground. The planting is to
compensate for felling of T10. The
existing tree site will be enlarged to become a wide tree strip to
accommodate at least six trees. The
entire strip of land that accommodates T1 to T4 should be revamped to improve
the soil condition for future tree growth.
The new
tree strip should be 4 m wide and covered by porous unit pavers to permit the
entry of rain and irrigation water and air exchange between the soil and the
atmosphere. The unit pavers should be
supported by small columns to create a vault-like structure so as to avoid
compaction of the underlying soil due to pedestrian trampling. The unit pavers
will be movable to provide access to the soil underneath so that fertilizers
and conditioners could be added on a regular basis. The air
conditioner unit currently located near the proposed planting site should
also be removed. This
new tree planting site should also be provided with proper irrigation. Pursuant
to the “Environment, Transport and Works Bureau Technical Circular (Works)
No. 3/2006 Tree Preservation”, the compensation ratio should preferably be
1:1 according to trunk girth. T10 has
a DBH of 20 cm (Table 4.3), and it
is proposed that six trees of heavy standard size be planted, each with a DBH
of around 10 cm and root balls of not less than 0.75 m diameter and 0.75 m
depth,. Since
the aggregate DBH of the new trees would be 60 cm, the rate of compensation
is equivalent to three times the DBH of T10, far beyond the requirements The six
replacement trees should be planted in the new tree strip in two staggered
rows, maximising distance between each tree to avoid mutual interference in
the future. It is recommended that the
species selected should have a small final dimension of
less than 10 m height given the proximity to built structures such as the
retaining wall and buildings. Two each
of the outstanding and related flowering tree species connected to local
natural history are suggested:: -
Bauhinia ‘Blakeana’ a native evergreen species with deep mauve
flowers and an exceptionally long flowering period from late autumn to early
spring. -
Bauhinia
purpure, a native
evergreen with lighter purple flowers from late autumn to early winter. -
Bauhinia
variegata, an exotic
deciduous species, with pale pinkish flowers in spring to early summer often
when the tree has little or no leaves. |

Vertical
Greening Within the limitations of the conservation
of the CPS character, greening of vertical structures should be provided
where possible. As such
it is recommended that the inner southern wall of the Site be planted as a
green wall. The plantings should be
inserted in between each of the large protruding piers and an offset be made
from both the top and bottom edge so that old and new are equally
visible. An independent frame should
be strategically positioned in order to ensure minimal disturbance to the
original wall, and provide the main structural support and planting surface
for the green wall. The frame on to
which the new green will be planted should contain its own irrigation system
so that moisture for the plants will remain mainly on the planting surface
and not the exiting wall behind. The
planting chosen should be appropriate to the |
