At least 50% of connector plate must overlap thewall plate

End trussed rafters normally placed no morethan 50mm from the gable

Strap gables to rafters, straps to be fitted to theunderside rafter members

Tie down rafters to wall plate using proprietarygalvanised truss clips

Chevron bracing - to be at approx. 45 degrees andnailed to at least 3 trusses

Diagonal bracing - running from eaves to ridgefixed to underside of rafters at 45 degrees to theline of the rafters

PITCHED ROOFVENTILATIONMaintain a 50mm airgap above insulation inthe roof pitch toventilate roof. Provideopening at eaves levelat least equal tocontinuous strip 25mmwide and opening atridge equal tocontinuous strip 5mmwide to promoteventilation.

STRAPPING FOR PITCHED ROOF Gable walls should be strapped to roofs at 2mcentres. All external walls running parallel toroof rafters to be restrained at roof level using1000mm x 30mm x 5mm galvanised mildsteel horizontal straps or other approved toBSEN 845-1 built into walls at max 2000mmcentres and to be taken across minimum 3rafters and screw fixed. Provide solid nogginsbetween rafters at strap positions. All wallplates to be 100 x 50mm fixed to inner skin ofcavity wall using 30mm x 5mm x 1000mmgalvanized metal straps or other approved toBSEN 845-1 at maximum 2m centres.

ELECTRICAL All electrical work required to meetthe requirements of Part P(electrical safety) must be designed,installed, inspected and tested by acompetent person registered undera competent person self certificationscheme such as BRE certificationLtd, BSI, NICEIC CertificationServices or Zurich Ltd. Anappropriate BS7671 ElectricalInstallation Certificate is to beissued for the work by a personcompetent to do so. A copy of acertificate will be given to BuildingControl on completion.

FIXED EXTERNAL LIGHTINGExternal light fittings to be fittedas calculated in the DER and incompliance with the DomesticBuilding Services ComplianceGuide.Light fitting to be either:a. lamp capacity not greaterthan 100 lamp-watts per lightfitting and provided withautomatic movement detectingdevices (PIR) and automaticdaylight sensors ensuring lightsshut off automatically when notrequired.Orb. lamp efficacy greater than 45lumens per circuit-watt; fittedwith manual controls andautomatic day light cut-offsensors so that lights switch offwhen daylight is sufficient.

LINTELS - For uniformly distributed loads and standard 2 storey domesticloadings only Lintel widths are to be equal to wall thickness. All lintels over750mm sized internal door openings to be 65mm deeppre-stressed concrete plank lintels. 150mm deep lintels are to beused for 900mm sized internal door openings. Lintels to have aminimum bearing of 150mm on each end. All pre-stressedconcrete lintels to be designed and manufactured in accordancewith BS 8110, with a concrete strength of 50 or 40 N/mm² andincorporating steel strands to BS 5896 to support loadingsassessed to BS 5977 Part 1.For other structural openings provide proprietary insulated steellintels suitable for spans and loadings in compliance withApproved Document A and lintel manufacture standard tables.Stop ends, DPC trays and weep holes to be provided above allexternally located lintels.

Smoke alarms should be sited so thatthere is a smoke alarm in the circulation space on alllevels/ storeys and within 7.5m of the door to everyhabitable room. If ceiling mounted they should be 300mmfrom the walls and light fittings. Where the kitchen area isnot separated from the stairway or circulation space by adoor, there should be an interlinked heat detector in thekitchen.

INTERNAL LIGHTINGInternal energy efficient light to be fitted as calculated inthe DER and in compliance with the Domestic BuildingServices Compliance Guide. Provide low energy lightfittings not less than three per four (excludinginfrequently accessed spaces used for storage, such ascupboards and wardrobes). Low energy light fittingsshould have lamps with a luminous efficacy greater than45 lamp lumens per circuit-watt and a total output greaterthan 400 lamp lumens. Fixed internal lighting to be pinbased fluorescent or compact fluorescent lamps or lowenergy bayonet or Edison screw base compactflorescent lamps.NEW GAS BOILERHeating and hot water will be supplied via a wall mountedcondensing vertical balanced flue pressurised boiler with amin SEDBUK rating of 90%.
