DESIGN REQUIREMENTS2.1 GENERALThis specification shall be for Class 1 buildings as defined by the Building Code of AustraliaHousing SA has produced a number of design guidelines. These are accessible on theDepartment of Communities and Social Inclusion web site. And more specificallyhttp://www.dcsi.sa.gov.au/services/housing-sa/housing-design-guidelinesAll proponents need to familiarize themselves with all the guidelines. These guidelinesprovide the background for the designs. Where there is a conflict the requirements withinthis document and the general guide lines this document shall take precedent.2.2 SPECIFIC DESIGN REQUIREMENTS2.2.1 GeneralThe design requirements as given in House Design Guide 1.1, Housing AccommodationSchedules 1.4 and Housing SA Universal Design Criteria 2.3 which are attached shall befollowed unless the ”Part B - Specification & Response Requirements ANNEXURE 1” specifyotherwise.Any specific design requirements that apply to a contract are given in”Part B - Specification &Response Requirements ANNEXURE 1”In addition designers are to allow for all items specified in SECTION 3 CONSTRUCTIONREQUIREMENTS. The minimum requirements within the guides shall be considered asfixed minimums for this type of housing.2.2.2 MaintainabilityPublic housing is generally used as rental property for a significant part of its life. Themaintenance of the property is the responsibility of the South Australian Housing Trust.Proponents are to consider in their designs the costs relating to ongoing maintenance andare to ensure that their proposals are low maintenance.In particular consideration is to be given to :-• Using materials that require minimal maintenance• Using low maintenance finishes• Ensuring that there is the appropriate access to maintain the building and services.2.2.3 Grading of Outdoor Areas2.2.3.1 General PrincipleWhere possible bench sloping sites to form a single near level private yard space adjacent tothe main living areas of the house/unit and to perimeter paving and driveways.Page 14 Updated 19/07/2013

General ConstructionPart B – Specification and Response RequirementsAnnexure 2- Minimum Design & Construction Specification2.2.3.2 Useable Private Open SpaceThe useable rectangular area specified in the Design Guide is to be sloped at flatter than 1 in50 and appropriately drained to the storm water system. It is to be in addition to and havestepless access from the perimeter paving.2.2.3.3 General Open SpaceOn very steep blocks and subject to Trust approval it may be acceptable to bench the rest ofthe yard area to a maximum gradient of 1:14 or it may be acceptable to incorporate retainedsteps in the benched site provided access to the whole of the site is achieved, with maximumgradients to each part of the site of 1:14.Where steps in the benched site are approved they shall be linked by paved concrete rampsnot steeper than1:14. Steeper short ramps designed in accordance with the requirements ofAS 1428.1 may be used subject to specific written SAHT approval.All out door areas are to be graded away from the house and drained towards sumpsconnected to the storm water system. Front yards may graded to the street without anysumps where levels permit.2.2.4 Retaining WallsLocate retaining walls under the fence line or more than 1000 mm from the fence line.Where the site works creates level differences between the site and the adjoining propertiesprovide an edging or retaining wall under the fence.Where the difference is greater than 200 mm a retaining wall, rather than an edging, isrequired. All materials used as kerbs or retaining walls must be durable. Reinforced concreteor galvanized steel posts with reinforced concrete sleepers are the preferred options.Timber sleeper walls are not to be used but other durable systems can be designed forlandscaping walls. Standard details of acceptable walls are attached.Provide an engineering design and Building Rules approval for all retaining walls to beincluded as part of the contract documents..2.2.5 Finished Floor LevelsUnless a rear of allotment stormwater connection is available set the FFL level for allhouses/units a minimum of 300mm above the top of the kerb level to allow for site drainageto the street. The lowest point on the kerb in front of the house or allotment may be used.On group sites the floor levels of units further from the road will need to be raised anadditional amount.Provide any additional fill, grading and retaining walls that are required to achieve this floorlevel and eliminate the possibility of water ponding.2.2.6 Fencing2.2.6.1 GeneralAll fencing shall comply with any Development/Council Guidelines and Encumbrancesapplicable for the project location. Where these requirements call for fencing to a higherstandard than that set out in this document, that fencing is to be included in the Proponent’sproposal. The Proponent is to allow for the full cost of fencing for the development.Page 15 Updated 19/07/2013

General ConstructionPart B – Specification and Response RequirementsAnnexure 2- Minimum Design & Construction SpecificationEnsure that the houses and rear yards will not overlook existing houses to the rear or sideyards and that consideration for neighbouring properties is respected. This may requireadditional retaining walls or fencing that separates properties, and shall be included in theBuilder’s proposal.The Builder shall consult and cooperate with existing neighbours regarding timing of anydemolition to existing fences to be replaced, the type and colour of the replacement fencing,as well as any retaining walls required, to minimise disputes.The Builder shall negotiate with all existing neighbours and shall manage any fencing noticesfrom neighbours on behalf of SAHT2.2.6.2 Fence typeFully fence each house/unit at side and rear boundaries with minimum 1800mm high cappedColorbond fences.Provide screen fencing behind the front alignment of the house and at least one 900mm widehand gate including a padlock, front latch tail and latched at the wall to allow full accessaround the house.

Pop up or remote floodgully away from the house are acceptable.2.2.7.4 Driveways.Driveway paving shall be a minimum of 3000mm wide within the property.Set driveway grades so that a fully loaded family car, eg. Commodore/Ford Station Wagon,will not “bottom out” on the paving, or the Council crossover. Do not exceed a gradient of 1:5at any point Driveways steeper than 1:14 are not suitable to be used as part of theadaptable access to the house from the street. Particular care is to be taken to match thedriveway with the any entrance paths or porches to avoid any steps or inappropriate rampsor slopes.Driveways shall not be located within 600mm of the ETSA pillar or water meter. Where it isnot possible to design the driveway 600 mm away from the services, they are to be relocatedat the Builder’s expense.2.2.8 Garage or Carport.2.2.8.1 GeneralIt is preferable that Carports/Garages are linked to the main roof unless restricted by theallotment design, in which case a freestanding carport/garage may be accepted..The carport/garage shall have a Colorbond steel roll-up door to suit standard 2400 mmopening with keyed lock.Provide access into the rear door of the house from the carport/garage or directly into thehouse. Door(s) from the carport/garage into the house or rear yard are to be an external doorkeyed alike to the house and fitted with weather seals. Door furniture is to be the same asfor the external doors of the house.Where attached units are attached at the carport/garage, a common double leaf masonrywall to the underside of the roof is required as a party wall on the boundary or the walls of thehouses within the carport/garage are to be fire rated to the roof of the house.2.2.8.2 CarportsThe wall between a carport and the house shall be constructed inthe same materials as theexternal walls of the house.

Front and rear yard spaces shall be effectivelydrained to ensure that site stormwater does not pond on the site or flow to and from adjacentproperties. Where allotments have a backfall with rear easement drainage connections, roofand site stormwater is to be connected to these.It may be necessary to install yard sumps connected to a separate storm water pipe systemand not be connected through the roof stormwater pipes (refer ”Part B - Specification &Response Requirements ANNEXURE 1”). Provide sufficient sumps to drain all yard spacesto ensure stormwater does not pond.Sealed stormwater systems are not acceptable unless specifically approved by the Trust dueto specific site conditions. ”Part B - Specification& Response Requirements ANNEXURE 1”.The use of pumps in stormwater disposal systems is strongly discouraged. Proponents willneed to show that all other alternatives are not possible/viable before a pumped stormwatersystem will be considered. Any proposed use of such systems must be approved by SAHTprior to preparation of Construction Drawings for presentation to Council, etc.Page 18 Updated 19/07/2013

General ConstructionPart B – Specification and Response RequirementsAnnexure 2- Minimum Design & Construction Specification2.2.10.2 Retention and Detention TanksAn on-site above ground Stormwater Retention system plumbed into the WC cistern(s) isrequired on all houses as detailed on SAHT Drawing SK 01 (Rev B) attached.Each individual house shall have a minimum of a 1000 litre rainwater tank permanently fixedon a suitable structural galvanised steel stand supported on a concrete footing systemdesigned for the site conditions. The tank shall be connected from roof gutter to top of tankvia an overhead downpipe capturing not less than 50 m 2 of roof area. . The gutter runs shallbe as long as possible with a fall of 1:500 to capture the largest possible area. The roofshape, gutter size and down pipe layout shall be designed to allow for this.Roof stormwater to the tank shall not be connected via a sealed system.If a detention tank is required by the relevant Council, the overflow from the rain water(retention) tank is to be connected to the detention tank and from the detention tank to thestormwater drain. The detention tank is to be designed to be installed in the space under therainwater tank stand where ever possible.2.2.10.3 Detention Special Regulatory RequirementsThe design Engineer is expected to utilise what design information is readily availablethrough either the various Councils websites or direct Council Officer contact. They are alsoexpected to have adhered to the hold points in design in this document. This is to avoid thepractice of presenting a design solution to Council which has no chance of complying. Failureto do this will result in design changes at the incumbent’s expense.Stormwater detention devices to be utilised based on increasing detentionrequirements:-1 Where Council’s stormwater management detention requirements of no morethan 1Kl per dwelling is satisfied by a minimum of 50m2 of roof capture or as much roof areaas can be captured by one downpipe :-Connect a minimum of 50m2 of roof area through a flying downpipe to a 1Kl retention tankabove a 1Kl detention tank (Housing SA, SK01 sketch).2 Where Council’s stormwater management detention requirements are above1Kl and up to 2Kl of detention per dwelling and satisfied by up to full roof capture:-Connect a minimum of 50m2 of roof area through a flying downpipe to a 1Kl retention tankabove a 1Kl detention tank (Housing SA, SK01 sketch). Connect as much of the balance roofarea as possible into a separate 1Kl detention tank via a flying downpipe. Have the tanksinterconnected with only one orifice control and ensure overflow will not be an issue.3 Where Council’s stormwater management detention requirements are above2Kl of detention per dwelling (ie post 100year flows reduced to pre 5 year flows) and wherethere is adjacent street drainage.Connect a minimum of 50m2 of roof area through a flying downpipe to a 1Kl retention tankabove a 1Kl detention tank (Housing SA, SK01 sketch). Connect as much of the balance roofarea as possible into a separate 2Kl detention tank via a flying downpipe. Have the tanksinterconnected with only one orifice control and ensure overflow will not be an issue. Anybalance detention requirement to be stored underground in the front yard of one of the frontdwellings and be able to gravitate into Councils underground street drainage with appropriatebackflow prevention if required.Page 19 Updated 19/07/2013

General ConstructionPart B – Specification and Response RequirementsAnnexure 2- Minimum Design & Construction Specification4 Where Council’s stormwater management detention requirements are above2Kl of detention per dwelling (ie post 100year flows reduced to pre 5 year flows) and wherethere is no street drainage.Connect a minimum of 50m2 of roof area through a flying downpipe to a 1Kl retention tankabove a 1Kl detention tank (Housing SA, SK01 sketch). Connect as much of the balance roofarea as possible into a separate 2Kl detention tank via a flying downpipe. Have the tanksinterconnected with only one orifice control and ensure overflow will not be an issue.Undertake stormwater modelling to determine what the shortfall in detention storage is. Thisis a hold point in design, present stormwater calculations to Housing SA to confirm apreferred solution.5 Where Council’s Stormwater management requirements are in excess of theabove, the priority of a preferred solution in catering for the additional detentionstorage in order is:-(a) Increasing the size of detention tanks providing there is room for the additionalfootprint (this has a ceiling),(b) Increasing pipe sizes for detention pipe storage (usually very limited due to pipecover & gutter discharge),(c)Shallow storage in the internal roadway and finally as a last resort a pump sump.(d) Consideration will also be given to some onsite soakage (WSUD) if the soil conditionsare suitable.2.2.11 Bathrooms2.2.11.1 Bathroom Special itemsAll bathrooms are to be provided with an exhaust fan ducted to atmosphere.Toilet cistern to be 4.5/3 litre flush and Caroma AIRE ULP when connected to a rainwatertank or a Caroma Concorde Trident with care buttons or equal when connected to mainspressure or a pumped rainwater system. .Where a shower is adjacent to a doorway or window a 200mm shower screen is required toprotect door frame or window reveal and mouldings.The main shower screen may be fixed on top of the end of the bath with overhang extendeddown to floor.The shower screen should be removable later with the tiling continuous under and behind thescreen.2.2.12 House FabricPage 20 Updated 19/07/2013

In some specific cases other options may be appropriate but should bediscussed with the Housing SA Senior Engineering Specialist before use.Different systems are appropriate for different conditions and so the required systems foreach specific situation are set out below.1. General Requirements1.1 Retreatment is normally to be carried out when there is a termite attack.1.2 When there is an attack on a building the whole of the building is to be treated. Insome cases this will result in the treatment of a number of attached units.1.3 In all cases the treatment will include a treatment around the exterior of the footing aswell as within the building. Exposed footing is not acceptable as perimeter treatment.1.4 The contractor is to record all work on a durable notice firmly secured within theelectrical meter box.1.5 Before any termite treatment is carried out the contractor is to check the meter box forthe notice of previous work and modify the extent of work as appropriate.1.6 Treatment of a local area is only to be undertaken when the termite barrier in thatarea has been disturbed and requires reinstatement.1.7 Whenever perimeter paving is added to a building perimeter treatment is to beinstalled. For replacement of local areas of paving or the addition of part of the perimeterpavement or where the treatment is disturbed by trenching treatment is required for that areawhere details of an existing perimeter treatment are in the meter box.1.8 Whenever Biflex is used it shall be used at a concentration to give greaterthan 10 years service life. (lower concentrations giving shorter life are NOT tobe used1.9 Contractors are to ask tenants if they have any health issues that may beaffected by the chemicals or the work before any treatment is initiated.1.10 If there are extenuating circumstances in which variation to the procedures isneeded approval is to be sought from the Housing SA representative prior toproceeding. The Housing SA representative is to note any tenant issues onHousing SA’s system.1.11 Contractors will generally be required to do a check and report to the HousingSA Representative prior to carrying out work. The report is to identify thelocation of the termites, the extent of damage, the entry points, any attachedPage 97 Updated 19/07/2013

If significant work or other unitsneed inspecting to complete the report a preliminary report is to be given tothe Housing SA representative detailing what has been found and advisingthe extent of work required to enable the inspection to be completed.2. Raft Slabs2.1 New raft slabsa) Preferred option is to protect penetrations with Termimesh, Kordon, Trithor,Smartfilm, Homeguard or uPVC “collars” and increase the reinforcement toRF92 for a 100 mm slab on ground, or RF82 for a waffle slab, (to controlshrinkage cracks) and to treat the perimeter of the slab as given in section 3.b) However, the detail at the bath outlet needs careful consideration. Any infillshall be protected by Kordon, Trithor, Smartfilm, Homeguard, collars orTermimesh. The use of a spray to protect the infill is NOT acceptable. IfuPVC “collars” are used then adjustment for the bath outlet is to be carried outabove the slab (e.g. larger pipe through slab and reducer to bath to give therequired tolerance). Where “Kordon” ,“FMC Homeguard” , “Smartfilm” or“Trithor system is used, the bath riser PVC waste pipe shall be protectedusing minimum 750 mm x 750 mm squares of “Kordon” ,“FMC Homeguard” ,“Smartfilm” or “Trithor as agreed by Housing SA with the licenced installer. Fortemimesh the riser shall be treated with the manufacturer’s special detail.Any damage which occurs to the termite protection (either “Termi-Mesh”. “Kordon” ,“FMCHomeguard” , “Smartfilm” or “Trithor”) shall be repaired by the licensed installer.Where foam or other block-outs are used in the slab around the bath riser, the block-out sizeshall not exceed 300 mm x 300 mm. Block-outs shall be backfilled with good quality concreteincluding cleaning, proper preparation of slab edge surfaces and priming prior to placementof the concrete.c) Granitgard is also acceptable.d) Under slab irrigation systems are not preferred as there is some risk of localfailure of any pipe system long term.e) Spraying of chemicals is not to be used2.2 Existing raft slabsThe following works are to follow the killing of the termites by the pest control contractora) Find the point of entry (This will often require the removal of wall linings and/orbrickwork) and treat the slab as follows:• for holes through the slab seal with epoxy.• for entry up the outside of the footing no slab treatment is required.• expansion joints in masonry cavities (usually these are party walls between units)• Clean the cavity (this may involve removing part or all of the base of 1 leaf of the wall(i.e. may have to under set 1 leaf).• Install a Termguard or similar irrigation pipe over the joint (in general this can be doneby removing a few bricks in the outside and sliding the pipe in).• Pump the system with chemical.• expansion joints in floor area.• Expose the joint for its full length.• Grind down the slab slightly.• Parge a piece of Termimesh with an expansion fold over the joint. This is to extendthe full length of the joint and down the external face to below the perimetertreatment.Page 98 Updated 19/07/2013

General ConstructionPart B – Specification and Response RequirementsAnnexure 2- Minimum Design & Construction Specification• Replace floor covering allowing for expansion at the joint. For vinyl flooring aproprietary expansion strip is to be usedNOTE: All of the above areas are to be treated even if they are not the current point of entryb) Where entry point is unknown• Drill at 300 mm MAX centres and inject with Chlorpirofos , Biflex or Premise as follows• 1 row of holes approx 100 mm from both faces of the walls in the area of attack (for cavitywalls it is not necessary to treat between the leaves.)• 4 holes around each slab penetration including the bath.• Seal up edge beam penetrations for electrical wiring, telecom, etc.• Treat any expansion joints as above.3. Perimeter TreatmentAs a large number of termite attacks are via the exterior of the footing this is a critical part ofthe protection system and is to be used in all cases. The objective is to force the termitesaway from the face of the footing so that they will have to travel back over the paving to getto the house.3.1 Initial Installation or Prior to New PavingThe following systems are acceptable• Hand Spray – Not suitable under pavers as will be breached by bedding sand and jointsbetween pavers.• Chemical Irrigation System – preferred system under pavers as chemicals will rise up intobedding sand.• Granitgard – Not suited under pavers (as per spray).• For a Kordon, Trithor, Smartfilm or Homeguard systems, extend Kordon, Trithor,Smartfilm, TMB or Homeguard 300 mm under concrete pavement – Not suited to pavers(as above).• Termimesh parged to footing and embedded in concrete paving. – Not suited to pavers• For a garden bed with no paving provide a 300 mm wide concrete edge strip over theedge treatment.3.2 Walls on Boundaries (zero lot line)New ConstructionTermguard have developed a system where a rebate is provided in the footing and theyinsert an irrigation pipe and pump it with chemical. Other treatments simply push the entrypoint further up the wall and are not recommended.ExistingApart from cladding the wall in Termimesh, Homeguard, Trithor, Smartfilm or Kordon, there isno treatment that is going to give a good level of protection, without putting the neighbour atrisk. Where it is considered necessary by the Housing SA representative to obtain someprotection bond Kordon, Trithor, Smartfilm, TMB, Homeguard or Termimesh onto the footingand extend up the wall 300 mm above the neighbour’s finished level.3.3 Treating Existing PavingWhere the paving is against the footing, drill the paving at 300 mm max centres and adistance between 100 mm and 120 mm from the footing face and inject a chemical barrier.Page 99 Updated 19/07/2013

General ConstructionPart B – Specification and Response RequirementsAnnexure 2- Minimum Design & Construction SpecificationFor pavers lift the pavers treat the soil and relay pavers directly onto the treated soil. Wherethe paving is against a wall, i.e. above the footing, the paving is to be lowered to below thetop of the footing and then treated as new paving. Where the levels make this impractical, aspecial site specific detail will need to be agreed. The detail is to be prepared by thecontractor and approved by the Housing SA Engineering Consultant.4. Timber and Other Suspended FloorsSuspended floors can be treated by cleaning the debris from under the floor and thenspraying the dirt with Chlorpirofos, Biflex or Premise. While other systems such asGranitgard, Kordon, Trithor, Smartfilm, TMB, Homeguard or reticulation systems could beinstalled for suspended floors, spraying is considered the most economical.4.1 Masonry (stone or brick) dwarf walls with no concrete footing.Special care needed to ensure termites can not come up through the wall.Inject soil under wall prior to spraying making sure that the solution totally saturates soilunder wall. (NOTE: For wide dwarf walls it is recognised that this may not be possiblewithout causing a footing failure and in those circumstances the soil under the footing is to betreated from both sides of the footing and the Housing SA representative is to be advisedthat the barrier under the dwarf walls may be incomplete.4.2 Timber StumpsSaturate the soil around the stump to at least 150 mm depth and ensure ant caps are inplaceAt the junction of stumps and perimeter paving ensure continuity of barrier from under thefloor to 300 mm under the paving. (Inject from under the floor and through the paving ifnecessary5. Treatment of Mixed Floors(a)(b)(c)(d)Where the main part of the house is a suspended timber floor and the wet area is aslab on ground, the following applies:Timber floor to have under floor sprayFor a sound slab treat around the walls. Drill holes at 300 mm maximum centres100 mm from the wall face and inject Chlorpirofos, Biflex or Premise. Treat aroundall service penetrations (4 holes per penetration) including the bath.For a floor in poor condition, i.e. cracked, drill the whole slab at 300 mm maximumcentres and inject chemical. Note: If the slab is in this condition, it may beadvisable to repair or replace the slab. (The contractor is to refer to Housing SArepresentative before proceeding)6. Replacement of Wet Area FloorsWhere wet area (bathroom, toilet, laundry) slabs on fill are replaced, treat under the slab withKordon, Trithor, Smartfilm, TMB, or Homeguard. Place a layer of Kordon, Trithor, Smartfilm,TMB or Homeguard on top of the sand over the entire area and extend at least 50 mm underadjacent floor slab or turn up the Kordon, Trithor, Smartfilm, TMB or Homeguard against thewall for the full depth of the slab. Penetrations shall be detailed with Kordon, Trithor,Smartfilm, TMB or Homeguard in accordance with the manufacturer’s recommendations.7. Baiting SystemsPage 100 Updated 19/07/2013

General ConstructionPart B – Specification and Response RequirementsAnnexure 2- Minimum Design & Construction SpecificationThese are generally designed to kill a nest rather than provide long term protection. Somesystems such as Sentricon use bait sticks and regular inspections to identify new termiteactivity.The systems have an application, particularly in groups of units where termite attack hasoccurred in several units, but the location of nests is unknown and protecting the building(s)is difficult or expensive.There is an ongoing maintenance costs but on such sites the elimination of the nests may beworth it. They are to be carefully considered for specific sites only and recorded as for a trial.The Housing SA representative is to provide approval for the installation of these systems.Page 101 Updated 19/07/2013
