Concrete Wall Panels – 200mm reinforced precast
concrete solid wall panels to be used for the
stairsand lift shaft to provide structural strength and
achieve the required fire rating in accordance with
TGD B. On the inside face of the Concrete Panels
there is a 25mm service shaft for services in the Lift
or Stairs, this service zone shall be framed out with
25mm x 50mm vertical timber battens, finished with
12.5mm gyproc board and a 2.5mm plaster skim
finish. the panels are also relatively soundproof so
this will eliminate sound transmission throughout the
building. The internal panels will have a 25mm
service cavity in between. Both sides of the Concrete
panels are to be left exposed.
Dance Studio:
Proposed:
Structure: Each Glulaminated Columns to be
supported by Steel Shoes that are bolted into the
Existing Cast in place Roof of the Mill Building. The
Roof shall be levelled off with concrete first so the
Columns have a level surface to bolt into, to
engineers specification.
External Wall Build up : From Exterior: 50mm
Terracotta baguette cladding fixed back to a vertical
steel Aluminium profile with a 76 x 38 mm Steel C
Channel to carry the cladding. 15 mm Cement
Particle Board is fixed back to 150 x 38 Vertical
Timber Studs @600c/c , 150mm Mineral Wool
Insulation is packed tightly between the studs with a
vapour Control Membrane placed to the face of the
Insulation, 15mm Cement Particle board is then
placed in front of the Membrane. The Cement
Particle board is finished with a 2.5mm plaster skim
finish.
Floor Build up : Existing Roof Structure is
protected by a waterproofing membrane placed on
the existing roof ,with joints lapped and sealed to
avoid any moisture entering the existing building.
97 x 217 mm Metal Web Floor Joists are placed on
top of the existing roof structure @ 400 c/c , mineral
Wool insulation is then packed tightly between the
joists. 200mm Cross laminated floor panels are then
placed on top of the joists and connected by metal
angle brackets to the joists. A proprietary sprung
floor system is then placed on top of the CLT Floor
structure.
Sprung floor Build up: From Exterior: 3 layers of
75 x 25mm Southern Pine Counter battons are laid
at right angles to one another, 10mm elastomer
pads are placed underneath the first row to provide
shock absorption. 12mm Marine plywood is
adhesively fixed on top of the battons with a 9mm
hardwood floor finish to clients specification. This
system is the Harlequin Woodspring basketweave
system.
Roof Build up :From Interior 704 x 6000mm
Double Radiant Heat Panels connected to glulam
Columns using eye bolts and spring hooks, 90 x
360mm Glulam Purlins to span along gridlines ,
60mm Trapezoidal steel liner sheet shall sit on top
of the purlins with vapour control layer placed on top
with all joints to be lapped and sealed. 100 x 1200 x
2400 Rigid Polyisocyanurate foam board insulation
is placed on top with 200mm Mineral Wool packed
tightly between Stainless steel reinforced GFRP
clips. 3mm Metal Profiled top sheet is placed over
the Mineral wool insulation and mechanically
seamed over head of support clips which is done off
site. 4mm Alucobond Panels are fixed to the 70 x 40
x 2 Aluminium box profile with a 80 x 45 x 3mm
Aluminium U Fixing.

General Repair Works
General Notes:
-Before any repair works take place on
site a full structural appraisal should be
carried out on the building.
-A conservation specialist shall carry out
all repairs and demolishion on site .
- A Conservation Architect should be
consulted prior to any works
commencing on site.
East Elevation:
-Removal of Ivy
-Repointing of Random Rubble Stone
Wall
-Removal of Concrete Window Frames
- Removal of possible Aesbestos grill
windows
North Elevation
-Demolishion of portion of the North
Facade see figure 1 & 2 .
- Strip the exisitng assumed Sand
Cement Render from the Wall and re
render using a lime base render.
South Elevation
-Removal of Ivy
- Repointing of Random Stone Rubble
Walls
- Removal of Concrete Window Frames
- Removal of Graffiti
- General Repairs to Concrete Wall
West Elevation
-- Repair to Concrete Walls , eg spalling
cracks, steel projections etc
Demolition & Removal of Materials on
site
Proposed: Demolition of the North and
West Wall of the Silo, based on the site
survey carried out on the 21-09-14 the
composition of the wall is a mix of
materials varying from concrete, block
work and sand/cement render The
relevance of this wall is not deemed as
being important in a conservation
context, it has been decided to demolish
the two walls and the proposed new
construction will act as the new main
entrance to the Building.
All materials from the demolition of
these two walls will be carefully took off
site and disposed of carefully .
There is an assumed Aesbestos Roof on
the Silo block of the building. Aesbestos
is an extremly dangerous material if
handled incorrectly, the material should
be taken off site immediately after
removal and disposed off under current
regulation by a specialist .
Excavation
The earth that is left over from the
proposed Excavations on Site shall be
reused on site wherever possible for
planting etc.
