TAFE NSW CPCCBC4001A: Building Codes and Standards Code Solutions

This document presents solutions for the CPCCBC4001A assessment, focusing on applying building codes and standards to low-rise building projects. It includes analysis of construction methods, distinguishing between DTS and Performance solutions, and explaining compliance with the National Construction Code (NCC). The assignment addresses various construction scenarios, such as XLAM subfloors, standard bearers and joists, Alucabond cladding, and waterproofing, providing explanations and proposed solutions. Furthermore, it examines fire safety elements as per NCC Volume Two, including fire resistance levels (FRL), passive and active fire protection, and compliance checks for existing buildings, with references to relevant sections of the NCC and other resources. The document aims to demonstrate understanding of building codes, fire safety, and their practical application in construction projects.

Assessment details Instructions
Assessment overview The objective of this assessment is to assess your knowledge as would
be required to access, interpret and apply relevant building codes and
standards applicable to the construction processes of residential and
low rise commercial buildings (low rise' licensing classification with
reference to Class 1 and 10 construction and Classes 2 to 9 with a gross
floor area not exceeding 2000 square metres, not including Type A or
Type B construction).
To successfully construct low rise buildings requires a thorough
knowledge of the purpose and content of the Building Code of
Australia (BCA), coupled with the ability to interpret other codes and
standards related to a specific building.

Task 1: Short answers – Code Solutions
Read each question carefully.
1.1 You are required to analyse the following construction methods and problems to be resolved.
Determine which type of solution (DTS or Performance) can be achieved. Explain and propose how
your solution has been determined. Using manufacturers’ technical specification as required:
Construction method /
problem
Performance
Solution
or DTS
Solution
Explanation
a. XLAM subfloor/ flooring
system
https://www.xlam.co.nz/
Problem: To design with
minimal lintel support.
DTS is achieved
using the XLAM
Design Guide.
The guide provides the necessary data on
how to design the lintel support structures.
For instance, commercial floor spans that
reach 7m can be achieved without the need
to add any intermediate support.
b. Standard Bearers
and Joists
(designed as per AS 1684)
Class 1
Problem: To design with
necessary structural support
Residential
timber framed
construction.
Part 1 of AS 1684 sets out the basis for
calculating timber sizes and forces to be
resisted by bracing and tie-downs. Reduced
joist spacing relatively improves the floor
performance by increasing assembly
stiffness.
c. Alucabond cladding.
All classes
Problem: Design a more
aesthetic approach
Design a wide
colour range
with excellent
fire
performance.
Designing alucabond with a more aesthetic
approach have added extra features like
durability and better fire performance
offering a rigid, light weight and weather
resistant performance solution.
d. Waterproofing as per AS
3740 Class 1
Problem: Ensure no structural
damage within wet areas
Building
elements in wet
areas must be
waterproof or
water resistant.
This guideline provides waterproofing and
water resistant requirements for building
elements in wet areas like shower area,
areas adjacent to spas and baths as well as
areas around the showers.
e. Spa panel wet area
systems. All classes.
https://www.spapanel.info
Problem: Ensure no structural
damage within wet areas and
Spa panel is
designed and
constructed
using a hard
wood
waterproof
The guideline makes spa panel 4x faster to
install than tiles, with minimal maintenance,
100 % grout free, and can be installed
directly onto the framework. Joints are
connected using a hydro lock system that

1.2 You should refer to this website:
https://www.kingspan.com/au/en-au/products-brands/insulated-panel-systems/roof-panel-
systems/trapezoidal-roof-ks1000-rw
to answer the following:
Construction method / problem – Trapezoidal Roof System – has been selected for a future
project to allow an innovative method that is cost effective and ensures improved time
management. Your certifier is happy with the product but you need to confirm how this
product meets compliance for the National Construction Code due to the fact it is not within
the Code (acceptable construction) and cannot be deemed as a DTS solution.
Use Volume One or Two to explain the process to ensure compliance for a Performance
Solution (Formerly known as Alternative Solution).
As of 2016 the Trapezoidal Roof System passed through the necessary technical as well as fire
standard tests in Australia. Currently, the Trapezoidal Roof System (KS 1000 RW) is Code mark
certified to comply with various sections of the Building Code in Australia. For further information
about the Code mark certificate one is to refer to the ABCB website. This means that the frames of
the Trapezoidal Roof System complies with the performance requirement ABCB. Similarly, the
roof system has been designed in accordance to AS 1684 NCC Volume Two therefore it can be
used in cyclone areas.

Task 2: Short answers – Fire Safety
Read each question carefully.
2.1 Identify and list the correct fire safety elements as per the NCC Volume Two:
 Ensuring the safety of the occupants of the building from injury by alerting them that the
building is on fire and they need to evacuate.
 Ensuring the fire doesn’t spread in any way.
 The building is to be protected from any harm that may be as a result of bushfires.
 Reduction of the number of fatalities that may result from prior evacuation of occupants
of a Class 1a building due to the likelihood of exposure to a bushfire.
2.2 Identify and apply the correct fire control elements for the scenario shown
(Note: The student should identify whether the scenario is Passive or Active)
Scenario Type of fire control element (Passive / Active)
Smoke alarm Active
Masonry party wall Passive
Fire sealant retardant Passive
Fire sprinklers Active
Fire blanket Active
Fire extinguisher Active
Non – combustible building materials Passive
Fire separation Passive

2.3 Define the term Fire Resistance Level (FRL) with reference to the National Construction Code:
FRL refers to the grading periods in minutes that is determined according to the structural
adequacy, integrity, and insulation1.
2.4 Determine the location (Table) of the National Construction Code for fire resisting levels:
NCC Volume One, page 33, Table C 1.1
2.5 Refer to the table determined for Question 2.4 above, what is the maximum rise of storeys Type
C construction for Class 2, 3 or 9 building?
3 storeys.
2.6 Refer to the table determined for Question 2.4 above, what is the maximum rise of storeys Type
C construction for Class 5, 6, 7 or 8 building?
6 storeys.
2.7 To check for fire compliance of existing buildings you are required to refer to the Fire-resistance
Level. Search NCC Volume One or Two and explain the FRL 60/60/60:
FRL 60/60/60 means that each element passed for the stated number of minutes, that is,
‘structural adequacy’ period of 60 minutes, the second is ‘integrity’ for 60 minutes and lastly is an
‘insulation’ period of 60 minutes.
