SOLUTION: Scope of the assessment | My Assignment Tutor

Name: Samrat Basnyat Cit Number: Cit260052 Assessment 1 Assessment 1 Building Codes, Standards and Compliance Assessment 1 – From scope of works to slab – including drawings and photographs This assessment must include in order, where applicable, the following. Scope of the assessment Answer: This assessment provides detail construction plan involved in the proposed residence. The site is located in a suburb of Gungahlin. The area of the site is 454m^2. This site is a two-storey residence. As per the given instruction the method of construction should involve strip footing, base brick and slab on ground, brick vaneer, sarked and tiled roof. The site must be compliance with the performance requirement according to BCA and should achieved deemed to satisfy or performance solution. Building classification ( NCC( A6) Answer: The building falls under a multiple classification according to A6.11 as set out in Building codes of Australia under building classification as the area of the garage(39.38m^2) is more than 10% of the site area(454m^2) therefore the building classification are: Class 1a as per A6.1.1 : a single dwelling being a detached house or one or more detached dwelling, each being a built, which is separated by a fire resisting wall, including row house, Terrance house, town house or villa unit.Class 10a as per A 6.10.1 as the garage is non habitable building like carport, shed or the like. Soil classification Answer: As the site is located in Gungahlin, the soil classification is M according to Table 3.2.4.1 which describes site as a “moderately reactive clay or site which can experience high ground movements from changes in the moisture”. Site works, including excavation, drainage etc. (including details of the unprotected embankment included on the plan) Answer: Given details: Location: Gungahlin -Soil classification: M Table 3.2.4.1 Height at the edge of the block 744.50 (744.60+744.60/2) FFL of residence: 744 According to BCA Schedule 3 and Table 3.5.3.1a Gungahlin falls under not low fall intensity area with 137(mm/h) average recurrence interval, once in 20 years. But what is low rainfall intensity? Surface water is to be diverted from class 1a building in compliance 3.1.3.3 which is what and why? Therefore, 150mm of slab is a requirement above the FFL. why –Unprotected embankment calculation -Slope firm clay ratio (Site cut) 1:1 according to Table 3.1.1.1 firm clay (M-E) Thickness of the slab = 150mm refer to 3.1.3.3b not thickness but height above FGL Slope away= 50mm Therefore, the total cut = 700mm Once the excavation is performed in embankment it should be protected by retraining walls. Why – I do not see where this is provided -Drainage system to be installed according to 3.1.3.1 and figure 3.1.3.2 how and why Please find the attached figure for the details. ` ` Termite risk management – spray chemical termite protection is not to be used -Using BCA and AS3660.1 Answer: Termite risk management for the site must be selected from table 3.1.4 and should comply with As3660.1, which is deemed to satisfy BCA requirement for a new buildings which includes steels, concrete, masonry, fibre reinforced cement and timber.. Component such as slab edge exposure, sheet material, granular materials should be combined to form a full system. This kind of physical barrier system will only deter the hidden entry but will not keep termites out. Please refer to the figure provided below: Details and reference for the picture given Any plumbing work has to be done 25mm far from the ground and rendering is not required. That is not the only reason – referenceTermite installation should comply with As 3660.1 and clasue 3.1.4.3 for the termite management.According to table 3.1.4.1 all system and components and attachment should be selected.Installation of termi mesh should be done to protect penetration as required.I need the full details of what and why things need to be done to meet the termite risk management requirements Footing construction – preparation to finish As the site given has a bearing capacity of 100 KPA for Class M site, below are the list of things that are used on the drawing for strip footing with referencing. Reference As per table 3.2.5.7(a) the depth of masonry veneer construction is 500mm and width of 300mm with the reinforcement of 3-l12TM on both top and bottom.As per table 3.2.5.6(b) Depth of footing DF= D+75= 575mmSlope angle should be 1:10 for the preparation and excavation from the part 3.2.2 with additional support from the trench mesh 3-L12Tm.Spacing between the bars are 400mm -where is that statedAll the concrete reinforcement should comply with part 3.2.3Concrete around the footing should be 20mpa for supporting the strip footing.- and …….. also needs referencing Overlaps of reinforcement, chairs, concrete coverage etc Slab construction – preparation to finish. Use Figure 3.2.5.5 for slab mesh sizes Slab construction refrence and details for the given figure. After the site are levelled in same area , we perform the under slab work.Bearing pressure20mm of sand cluster is compacted after foam work – what is foam workVapour barrier 0.2 mm nominal thickness film is installed as per BCA 3.2.2.6. tapped around the penetration – where and how is it installedSlab are made using waffle pods which are placed as per planned and required. – you need to read the assignmentChairs are placed to provide supports to waffle podsSlab mesh of Sl63 for slab length of less than 12mm is used as per figure 3.2.5.5Minimum lap for the reinforcement are done as per table 3.2.3.1All the penetration are protected from termishFinally concrete are poured according to AS2870 with the trapped air is less than 5% in concrete mixture and 20mpa concrete are poured for reinforcement.
