GENERAL UPDATES TO REFLECT CHANGESTO CIVIL POLICY DOCUMENTS

GeneralThis drawing is to be read in conjunction with document SUB-03-017 GeneralSpecification for the Civil Engineering and Building Design and Construction ofSecondary Substations. It is the constructor's responsibility to confirm, beforeconstruction, that the details on this drawing are correct as per SUB-03-017.

This is a generic guidance drawing that is deemed suitable for construction. Howeverthe constructor should consider all site specific risk that will affect the design andoperation of the substation. Proposed substation details are to be submitted foracceptance before installation.

Details shown on this drawing are typical for this type of substation building but maynot be suitable for substations housing alternative equipment. The constructor shallsatisfy themselves that the appropriate details shown are correct depending on thetype of substation being constructed.

ConcreteGeneralThe concrete shall be in accordance with the specification and attain the relevant cubcrushing strength at 28 days.

Foundations (Concrete 40N/mm² 28-Day Cube Strength)Foundations are to be set on undisturbed inorganic strata that provide the requiredminimum design safe ground bearing capacity. Minimum bearing capacity to be75kN/m².

Floor (Concrete 40N/mm² 28-Day Cube Strength)A flat, level and smooth floor surface is essential for installation of plant. Tolerancesto finished level expressed as a maximum permissible deviation beneath a straightedge with feet placed anywhere on the floor shall not exceed 1mm in 1m or 3mm in3m. Floors to be cured, prepared & painted with 2 No. Coats of non-slip floor paint oncompletion.

NOTES

GeneralThis drawing is to be read in conjunction with document SUB-03-017 General Specificationfor the Civil Engineering and Building Design and Construction of Secondary Substations. Itis the constructor's responsibility to confirm, before construction, that the details on thisdrawing are correct as per SUB-03-017.

This is a generic guidance drawing that is deemed suitable for construction. However theconstructor should consider all site specific risk that will affect the design and operation ofthe substation. Proposed substation details are to be submitted for acceptance beforeinstallation.

Details shown on this drawing are typical for this type of substation building but may not besuitable for substations housing alternative equipment. The constructor shall satisfythemselves that the appropriate details shown are correct depending on the type ofsubstation being constructed.

ConcreteGeneralThe concrete shall be in accordance with the specification and attain the relevant cubcrushing strength at 28 days.

Foundations (Concrete 40N/mm² 28-Day Cube Strength)Foundations are to be set on undisturbed inorganic strata that provide the requiredminimum design safe ground bearing capacity. Minimum bearing capacity to be 75kN/m².

Floor (Concrete 40N/mm² 28-Day Cube Strength)A flat, level and smooth floor surface is essential for installation of plant. Tolerances tofinished level expressed as a maximum permissible deviation beneath a straight edge withfeet placed anywhere on the floor shall not exceed 1mm in 1m or 3mm in 3m. Floors to becured, prepared & painted with 2 No. Coats of non-slip floor paint on completion.

BrickworkGeneralAll brickwork below D.P.C. to be H.D. category 1 min. 75N/mm² mean compressive strengthand max 7% M.A. and durability designation F2 S2 (Ex Engineering Brickwork Class B) inEnglish bond except for exposed faces.External facing brickwork to be H.D. category 1 min. 30N/mm² mean compressive strengthand max 12% M.A. and durability designation F1 S1 or better.Internal facing brickwork to fair faced smooth textured solid concrete bricks, sized to matchexternal facing bricks and with a mean compressive strength of not less than 20N/mm².Class iii mortar.

WallsWalls shall be 215mm English garden wall bond or Collar jointed stretcher bond.Leaves of collar jointed double stretcher walls to be tied together by means of type 1 ortype 2 stainless steel ties laid in every fourth course at 375mm centres and set back 38mmfrom outer face, ties are to be staggered.

DoorsDetails of proposed doors shall be submitted to SPEN for comment, before workcommences.Proprietary GRP faced aluminium or steel security doors are the preferred option, unlessstated otherwise.An alternative option for hardwood doors (see Drg SP4000543 for details) or GRP doors isalso available.

Cable Trench & SlotsOn completion of cabling, cable trench and slots to be filled with dry sand topped with aminimum 150mm depth of rounded gravel chippings (top to be level with FFL).

RoofStandard Concrete Roofs (Concrete 40N/mm² 28-Day Cube Strength)Wherever practicable, roofs should be cast in situ reinforced concrete construction with asoffit finish. Slip joints shall be incorporated at wall bearings, polysulphide sealed externally.Internal / External faces of concrete to be fair faced. All external faces to be cured,prepared, primed and finished with a two coat high performance (Aliphatic) polyurethanewaterproofing system (flat roof grade) with glass fibre mat reinforcement to initial coat, e.g.




Where permanent structural metal soffit shutters are used as part of a composite roofsystem these shall be corrosion resistant and the Constructor's proposals for screening ortagging for earthing purposes shall be expressly agreed with SPEN prior to construction.

VentilationVentilation shown is typical for a single 500kVA transformer substation.Ventilation unit opening sizes for 1000kVA transformers shall be a minimum 1002 x 450mm.The typical ventilation indicated may not be adequate in certain supply conditions whichmight require additional or alternative ventilation arrangements.
