Assessment Of Competence In Applying Building Codes And Standards For Low Rise Building Projects

This assessment has been designed to allow you to provide evidence of your competence in the unit CPCCBC4001A Apply building codes and standards to the construction process for low rise building projects.

Note: you will need to complete additional assessments as you progress through your course to demonstrate competence for all aspects of the unit.

In completing your final assessments, you will show evidence of your ability to:

• Access and interpret relevant code and standard requirements
• Analyse and apply a range of solutions to a construction problem for compliance with the NCC/BCA.

To assist with this assessment, refer to Appendix A, B and C for relevant excerpts of the National Construction Code (NCC).

Read the scenario below and refer to the NCC/BCA to answer the four questions below.

Scenario

The building construction process has commenced for David and Tara King’s house and is progressing well. Jai, the builder for Sullivon Constructions, meets regularly with David and Tara to discuss ongoing building issues and to make decisions. At the last site meeting, David and Tara mentioned that they would like Jai to install an automated door at the rear of the house to allow easy wheelchair access for Tara’s disabled mother.

Jai is aware that the proposed automated door, will not comply with the Deemed-to-Satisfy provisions of the NCC/BCA & that he will have to consider a Performance or Alternative Solution, to accommodate his clients wishes. 

1. What are the four assessment methods & their reference numbers, Jai will use to ensure an ‘alternative solution’ satisfies the performance requirements of the NCC/BCA?

Refer to NCC/BCA V1 General Provision, Part A0 Application to aid you in your response.

4. Visit the policies section of the Sullivon Constructions

Locate the ‘Quality Policy’ and identify three aspects of the project that Jai would need to consider that could impact on the ‘alternative solution’ (for an automated door) requested by Tara and David), e.g. quality of materials and workmanship.

1.  b) What is the purpose of a landing?

1.   c) What is the minimum length of a landing?

Since the overall staircase height between floors = 3000mm and the maximum riser is 190mm.    

• 3000/190 = 15.78 risers, which we need to round-up to 16 risers.

Step 2:

Divide the height between floors by 16 risers provides the riser.

• 3000/16 = 187.5mm (Riser) this is good as max rise is 190

Step 3:

Draw 8 risers to a mid-height landing and follow up with an additional 8 risers.

Following the formula: 2R (riser) +G (going) = 630

Therefore:

2 x (187.5) = 375 + G = 630

Or

375 + G = 630

• 630 – 375 = 255mm (Going is 255mm)

Step 4:                                           

On Plan & Section below, provide a scaled 1:50 freehand drawing showing the x8 goings to the mid height landing, follow by an additional x8 goings run to reach the 3000mm floor to ceiling height.

Scenario

The building construction process has commenced for David and Tara King’s house and is progressing well. Jai, the builder for Sullivon Constructions, meets regularly with David and Tara to discuss ongoing building issues and to make decisions. At the last site meeting, David and Tara mentioned that they would like Jai to install an automated door at the rear of the house to allow easy wheelchair access for Tara’s disabled mother.

Jai is aware that the proposed automated door, will not comply with the Deemed-to-Satisfy provisions of the NCC/BCA & that he will have to consider a Performance or Alternative Solution, to accommodate his clients wishes. 

1. What are the four assessment methods & their reference numbers, Jai will use to ensure an ‘alternative solution’ satisfies the performance requirements of the NCC/BCA?

Refer to NCC/BCA V1 General Provision, Part A0 Application to aid you in your response.

Assessment Method 1: Jai should give evidence to support the use of materials, or form of construction meets the design performance requirement as described in A2.2

Assessment Method 2: Verification Methods such as: (i) the Verification Methods described in the NCC; or (ii)Other Verification Methods that are accepted by the appropriate authority for determining compliance with the Performance standards.

Assessment Method 3: The expert Judgement on quality standards

Assessment Method 4: Comparison with the Deemed-to-Satisfy Provisions

2. Provide a brief explanation of all four (4) ‘assessment methods & their reference numbers’’ as outlined in the NCC/BCA:

Assessment Method 1 & Reference Number: A0.5a Evidence is very important to give prove that alternative materials and door location satisfy the provisions in  the Performance Requirement or the Deemed-To-Satisfy standards set in A2.2

Assessment Method 2 & Reference Number: A0.5b The methods of assessment mainly include verification methods stipulated in the NCC or comply with the performance requirements.

Assessment Method 3 & Reference Number: A0.5c Experienced experts that have dealt with the relocation of disability access are likely to be involved in carrying out this assessment.

Assessment Method 4 & Reference Number: A0.5d The assessment method used should be in compliance with the provisions in the Deemed-To-Satisfy clause.

3. Give two examples of the documentation Jai would need to provide, (in relation to the proposed automated door David and Tara have requested), to comply with relevant NCC/BCA requirements?

Refer to NCC/BCA V1, Contents & features introduction, Documentation of decisions, to   aid you in your response.

1.    Deemed To Satisfy solution

2.    Expert Judgement

4. Visit the policies section of the Sullivon Constructions

Locate the ‘Quality Policy’ and identify three aspects of the project that Jai would need to consider that could impact on the ‘alternative solution’ (for an automated door) requested by Tara and David), e.g. quality of materials and workmanship.

1: The proposed planning, and functionality in terms of the spaces relationship; The proposed alternative solution should be functional and able to satisfy the needs of the client.

2: Workmanship: The quality of the automated door in the new location should be of high quality such that the workmanship appears uniform

3: The material quality: the material chosen should be of good quality to achieve the desired outcome by the client, one that is seamless and aesthetically appreciable.

1.  b) What is the purpose of a landing?

P3.9.1, Figure 3.9.1.1 A landing is required to halt a person’s fall.

1.   c) What is the minimum length of a landing?

P3.9.1.3h A landing should not be less than 750mm where a change in direction is involved or less than 500mm from an inside edge.

Fig 3.9.1.2 The maximum riser (R) dimension should be 190mm.

Fig 3.9.1.2 The minimum going (G) dimension should be 240mm.

P3.9.2.3c The maximum distance allowed between openings should be constructed such that they do not allow a 125mm sphere to pass through it.

P3.9.1.4

The maximum distance should be such that 125mm sphere must not pass through threads 

 Since the overall staircase height between floors = 3000mm and the maximum riser is 190mm.    

• 3000/190 = 15.78 risers, which we need to round-up to 16 risers.

Step 2:

Divide the height between floors by 16 risers provides the riser.

• 3000/16 = 187.5mm (Riser) this is good as max rise is 190

Step 3:

Draw 8 risers to a mid-height landing and follow up with an additional 8 risers.

Following the formula: 2R (riser) +G (going) = 630

Therefore:

2 x (187.5) = 375 + G = 630

Or

375 + G = 630

• 630 – 375 = 255mm (Going is 255mm)

Step 4:                                           

On Plan & Section below, provide a scaled 1:50 freehand drawing showing the x8 goings to the mid height landing, follow by an additional x8 goings run to reach the 3000mm floor to ceiling height.
