General Notes:
G1
This drawing is to be read in conjunction with all relevant
Architect's and Engineer's drawings and specifications. All materials and
workmanship are to comply with the Contract Specifications,
National/EU Codes of Practice as well as Local Authority requirements
where applicable.
G2
Please do not scale this drawing. All dimensions are in millimetres
unless noted otherwise. All details and dimensions, particularly those
relating to existing structure, are to be checked or verified onsite by the
Contractor/Subcontractor prior to commencement of
construction/fabrication. Any discrepancies are to be reported to the
Engineer and/or Architect.
G3
For final setting out information such as gridline to wall alignment
please refer to the Architects drawings.
G4
Routing of all mechanical and electrical services should be as
defined by the M&E Engineer and Architect. All horizontal and vertical
penetrations/openings in new and existing structure must be agreed with
the Structural Engineer before construction.
G5
The contractor must not undermine or compromise the integrity of
any existing substructure or superstructure. The Contractor is
responsible for all temporary works design (unless noted otherwise) but
should consult the Structural Engineer with any sequence or overall
building stability queries.
Foundation Notes:
F1
The Contractor must not undermine any existing substructure. If
the proposed founding depth is lower than existing adjacent substructure
the Structural Engineer should be consulted to determine underpinning
requirements.
F2
Depth of bearing strata and safe ground bearing capacity is as
defined in the ground investigation information. The bearing strata is to
be verified on site to the satisfaction of the Structural Engineer or
Building Control. Substructure must not be founded in made ground and
must have minimum penetration of 300mm into the bearing strata
identified in the ground investigation. All foundation excavations are to
be clean, flat and dry before concrete is poured.
F3
All unreinforced foundations to be in concrete grade GEN1 unless
noted otherwise. All reinforced foundations to be designated concrete
mix RC35 unless noted otherwise.
F4
All foundations are to be founded at a minimum ASSUMED depth
of 750mm below existing ground level. Founding depth to be verified by
ground investigation.
F5
All foundations have been initiallly designed using an ASSUMED
bearing capacity of 100kN/m². Bearing capacity to be verified by ground
investigation.
F6
All trench foundations are to be 600mm wide unless noted
otherwise. Foundation width to be verified by ground investigation.
F7
All foundations are have been initially designed ASSUMING a
high volume change potential soil. Volume change potential to be
verified by the ground investigation.
Concrete Notes:
C1
All concrete construction is to be carried out in accordance with
Curtins specification for reinforced concrete.
C2
All reinforced concrete is to be designated concrete mix RC35
with a minimum compressive strength of 35N/mm at 28 days
C3
Site blinding concrete is to be designated concrete mix GEN1 with
a minimum compressive strength of 10N/mm at 28 days.
C4
For full details of the reinforcement as denoted on this drawing
refer to the corresponding bar bending schedule.
C5
All high yield reinforcement including all mesh to be grade B500B
to BS4449 and BS4483 respectively. Other reinforcement to be mild
steel grade 250 to BS4449.
C6
Concrete cover to reinforcement to be:
25mm in slabs (top),
40mm in slabs (bottom),
40mm in footings to links,
50mm in pad foundations.
C7
Minimum lap length for mesh reinforcement to be 450mm.
Minimum lap lengths for loose bar reinforcement to be:
T12 - 500mm
T16 - 700mm
T20 - 800mm
T25 - 1000mm
T32 - 1200mm
C8
Reinforcement layer/alignment abbreviations.
T1 top upper layer.
T2 top lower layer.
B1 bottom lower layer.
B2 bottom upper layer.
EF each face
NF near face
FF far face.
Concrete Slab Notes:
SL1 Ground bearing floor slab is acceptable provided all topsoil and
Superficial Deposits are removed and the exposed bearing strata is to
be compacted prior to placing of granular fill. Granular fill to be laid in
maximum 150mm thick layers to specification/thickness indicated on the
foundation drawing.
SL2 The floor construction must provide minimum 450mm cover
against frost heave. Due to the risk of frost action it is advisable that
ground works within the chalk are not undertaken in the winter months.
Where construction must be undertaken in the winter reference should
be made to CIRIA C574 Engineering in Chalk section 7.1.2 Precautions
Against Frost Action.
SL3 Granular fill layers should be blinded with 50mm of sand where a
DPM is required. DPM specification including taping/lapping to Architect
or specialist details.
SL4 Ground bearing slab to be 175mm thick concrete grade RC28/35
with A193 top mesh and A393 bottom mesh.
Steelwork Notes:
Description:
Date:
By:
Chkd:
S1
This drawing indicates the design intent for steelwork elements.
The steelwork fabricator will produce fabrication drawings and
connection designs for all elements drawn and submit to the Structural
Engineer for review prior to fabrication. Similarly the drawings should be
submitted to the Architect to confirm dimensional/setting out accuracy.
S2
Connections shall be designed for the moments, shear and
torsion forces indicated on the drawings. All bolted connections shall
have a minimum of 2no 16mm diameter Grade 8.8 bolts (to BS3692)
unless noted otherwise. All welds shall be minimum 6mm fillet welds
unless noted otherwise. Bolts shall be zinc electroplated for internal use
and spun hot dipped galvanized for external use.
S3
Structural steelwork (including open sections and hollow sections)
shall be Grade S355 in accordance with BS5950 unless noted
otherwise.
S4
All structural steelwork shall be treated and painted in accordance
with the Curtins specification for protection of structural steelwork. As a
minimum requirement all structural steelwork shall be treated and
painted with a two pack high solids high build epoxy zinc phosphate
primer to 150 microns DFT. During construction any damage to
workshop applied paint treatment is to be locally re-applied after
completion of the frame.
S5
All fire protection and finishes to be as specified by the Architect.
S6
All steelwork below ground floor level to be encased in 100mm
thick RC30 concrete.
S7
Where steelwork is supported on padstones they shall be formed
from RC30 concrete and unreinforced unless noted otherwise. All steel
beams shall be fixed into the padstones with minimum 2no 16mm resin
or mechanical anchor bolts.
S8
All cold rolled elements are to be installed in accordance with the
manufacturer's recommendationds are to be supplied complete with all
necessary cleats, sleaves, anti-sag and fixing components.
