3. 3.4 Eurocodes and British Standards

   • The Approved Documents refer to Eurocodes, British Standards and other sources of reference include CIBSE documents and BRE papers
     • EUROCODES are harmonised European codes of practice encompassing British Standards – particularly in relation to structural design
       • BS EN 1996-1-1:2005+A1 2012 Eurocode 6: Design of masonry structures – Part 1-1: general rules for reinforced and unreinforced masonry structures

       • BS 9999: 2008 Code of Practice for fire safety in the design, management and use of buildings

4. 3.5 How are building regulations operated

   • Building Control Bodies
     • Building Control Bodies (BCBs) are empowered to approve or reject plans, set conditions for approval, inspect work, request evidence (e.g. FENSA certificates for windows) request opening up of works and issue completion certificates.
       • Local authorities
       • Approved inspectors if developer wishes to have private inspection
   • Obtaining approval to start construction
     • A fee is to be paid when submitting plans to the BCB
       • Approval
       • Approval with conditions
       • Rejection
     • There are two main types of plans
       • Full Plans - This is where drawings, details and other supporting information is submitted for checking and a formal decision notice (approval, conditional approval or rejection ) is given
       • Building Notice - This is a less detailed form of application where minimal information is initially required, although the Building Control Body may request further details. The Approval process is dependent on satisfactory site inspections by the Building Inspector and the supply of further details as requested
   • Obtaining approval of construction work to be inspected
     • For approved inspectors a contract for the building control service must be procured upfront
     • For local authorties a fee must be paid upfront
     • Notices
       • Notice should be given at least two days before work is due to commence
       • Prior to covering up work notice should be given one whole day before
         • Excavation for a foundation
         • Foundation itself
         • Any damp proof course
         • Any concrete laid over site
         • Any drain or sewer to which regulations apply
   • Obtaining a completion certificate from building control
     • Evidence including certificates that show testing and commissioning should be provided at request to Building control if required to show building regs have been met
       • Part B
         • As built fire strategy
         • Fire detection and alarm testing certificate
           • Normally issued following the commissioning of the whole system i.e fire detected, alarm, vents open, sprinklers on, fire dampers, hold open deveices
         • Emergency lighting certificate (should work upon power failure)
         • Confirmation that contractor has handed fire safety information to the building user
       • Part E
         • This test would be carried out by a specialist qualified for sound insulation testing
           • issue of the sound insulation test reports which must demonstrate that the actual difference in sound pressure levels across the separating wall construction or floor construction both for impact sound and airborne sound meets the limiting standards set out in Approved Document AD E
             • Dwellings, houses, flats and rooms for residential purposes shall be designed and constructed in such a way that they provide a reasonable resistance to sound from other parts of the building
             • D - difference
             • Dntw - reverberation time (time sound is disappearing)
             • dB - decibels
             • N - normalised for taking average range of sounds (minimum)
               • 45 through walls airborne sounds
               • 43 through floors airborne sounds
               • 43 through stairs airborne sounds
             • Lntw dB- Level of sounds pressure for impact
               • Maximum value - can’t be more than 62 dB (maximum volume of impact sound)
       • Part F
         • There is a requirement to satisfy Building Control that ventilation systems have been tested for air leakage and that air flow rates are proven as designed. The test results will be required. These are certified by the ventilation specialist with evidence of witnessing of tests by the designer
       • Part G
         • There is a requirement to satisfy Building Control that the actual water consumption meets the target. The calculation should be prepared by the designer for submission to Building Control
       • Part J
         • There is a duty for the installers of all gas systems including the gas fired boilers with flues, gas distribution pipework and the gas appliances to self-certify their workmanship and provide a “Gas Safe” test certificate as evidence of testing
       • Part L
         • Calculation to be carried out to ensure building is operating within co2 emissions and energy efficiency rates
           • Certificates come in the form of SAP's for dwellings, BRUKL for non dwellings,
             • Both are used to produce an EPC - energy performance certificate
               • Specialist accredited with ATTMA must carry out air permeability testing which must not exceed regulations in AD L
