Please type your answers in black font. (Calibri 12 point) It is recommended that you are familiar with the following resources and standards prior to completing this assessment: o Learning Resources for CPCCBC4011B o NCC Vol 1 o AS1170.1 Structural design actions – Permanent, imposed and other actions o AS1170.2 Structural design actions – Wind actions o AS3850.2 Prefabricated concrete elements – Building Construction o National Code of Practice for Precast, Tilt-up and Concrete Elements in Building Construction o AS3600 Concrete structures o AS4100 Steel structures o Code of Practice: Demolition Work o AS2601 The Demolition of structures You may make any assumptions you need to, but be sure to include them as part of your submission. Task 1 – Wall systems This assessment task is based on the following Project: Project 3 Factory Complex Job Address: 7 Layland Way, Banksia, NSW Job Title: Proposed Factory Units and Office Space Client: Tasmegs Development Pty Ltd Architect: Olympic Designs, 55 Olympic Parade, Homebush, NSW 2140 1. Study the wall system for the external and dividing walls in the factory units and answer the following: a) What type of wall system has been used? The type of wall system that has been used are prefabricated concrete panels with a paint finish. (Also known as Precast Concrete) b) What structural function(s) do these walls perform? (hint: what loads do they resist and how? Do they support any building components?) 2 LA023654, Assessment 4, CPCCBC4011B, Edition number 4 © New South Wales Technical and Further Education Commission, 2020 (TAFE NSW), Version 2, September 2020

Pre concrete panels can easily support multi-storey structures such as the project shown. They are quite strong and adaptable therefore the product can withstand a lot of weight. Precast has the highest levels of acoustic separation that is commonly used in the housing construction. Example: - Weight 10DT24 = 468 plf. - Roof Dead Load = 20 psf - Roof Live Load = 30 psf - Wind Load = 30 psf 2. When prefabricated concrete elements are used in a construction project, there are two stages to the design process. a) What design issues do these stages consider? Stage 1: Structural design – Completed by the Structural Engineer who will review the load requirements of the buildings construction and determine the appropriate wall thickness, height and overall design. Stage 2: Construction process – Determining how the concrete elements are handled, transported, erected and supported during the erection process. It can be completed by the Structural Engineer or the Engineer appointed during the construction phrase process i.e the concrete panel manufacturer. b) What loads must be considered in each of these design stages? (refer to Part 3 and Part 4 of Precast and Tilt-up Concrete for Buildings at https://vic.cfmeu.org.au/sites/vic.cfmeu.org.au/files/uploads/OHS/Alerts/Industry %20Standard%20%28Vic%29%2C%20Precast%20and%20Tilt-up%20Concrete%20for %20Buildings.pdf if you need help) The structural design of Precast concrete elements should be carried out whilst regulating with AS 3850 and AS 3600. They are to also take note of the provisions that come along with these regulations and Australian Standards. Structural members supporting precast or tilt-up elements needs to be designed such that they are subject to for the situation where the element may bear on only two discrete points during erection. In addition to the normal design considerations, special consideration should be given to: • Construction loads • Handling and transport loads or Impact loads • Erection loads • Wind load on the braced elements prior to incorporation into the structure • Seismic (earthquake) loads. c) What is/are the Australian Standard(s) most applicable when undertaking this type of construction?

Precast and tilt-up concrete elements should be designed and constructed in accordance with the Building Code of Australia and the relevant Australian Standards. This Industry Standard is intended to complement the key Australian Standards dealing with precast and tilt-up concrete construction, AS 3600 and AS 3850. d) What is the relevant (national) Code of Practice?  Work Cover’s Code of Practice for Building and Construction Workplaces.  Work Cover Safety Guidance for Housing Construction.  Precast and Tilt Up Concrete Construction AS3600  AS 3850.1 – 2015 ‘Prefabricated Concrete Elements’ e) Considering the transport and erection of large precast elements that are manufactured off-site, what issues need to be considered by the designers and the principal contractor prior to the preparation of shop drawings for a project? Prior to the preparation of the shop drawings, which should comply with the structural design, the following details should be considered  how the elements will be lifted for transport  the movement of materials and equipment  the required vehicle load capacity  where the elements will be stored  the clearance to adjacent structures  whether assembly can take place on ground, or if working at height will be necessary.  the allowances required for cranes and other lifting devices.  If there is any site limitation or access issues  Local street access  What the delivery sequence will be f) List 15 important items that should appear on the shop drawings for such elements. 1) Drawing Number 2) Date and Revision number of the drawing 3) Location of the project 4) Element number 5) Mass of each element 6) Dimension and center of gravity of elements 7) Reinforcement, Concrete Cover and Strands. 8) Standard Symbols used on the drawings – AS3850 9) Brace and Prop details for the concrete elements. 10) Concrete Compressive strength of the concrete element. 11) Class and Strength grade designation – AS3600 12) Erection Sequence. 13) Location of Grouting Ducts. 14) Location of Conduits – electrical, plumbing and cabling. 15) Reinforcement strands and concrete cover. 4 LA023654, Assessment 4, CPCCBC4011B, Edition number 4 © New South Wales Technical and Further Education Commission, 2020 (TAFE NSW), Version 2, September 2020

16) Concrete Element Dimensions. 17) Location, Orientation and Depth of all inserts and the size, configuration and concrete cover of any component reinforcement that is required. 3. There are a number of steps in the process of erecting this type of wall system. Outline the main issues that need to be considered in: a) planning the use of cranes on the site (for lifting the panels into place),  The feasibility of transporting a crane of the required type and capacity to lift the elements also needs to be taken into account.  Cranes and elevating work platforms should be selected and used in accordance with the appropriate parts of AS 2550  Review of any obstructions such as trees, overhead powerlines  Communication to the Site teams  High risk SWMS  Frames used to support elements during transport should be designed to withstand loads and forces acting on the system during loading, transportation and unloading. b) quality checks on the panels prior to commencing lifting,  Ensuring that the concrete strength of the precast elements has reached the design strength for transport and erection.  Ensuring that the elements are loaded in a sequence compatible with the required unloading sequence on site.  Restricted access to loading zones  ITPs are completed by Manufacturer, site team and Engineer. c) steps to be taken prior to commencing erection, and  Crane Inspections are completed and deemed safe to operate.  High Risk SWMS are completed.  Brace Footing and Element Concrete must have specific strength.  Locating the dowels and levelling shims are located in the correct spot.  Room for crane outriggers, broom swings and counterweight tail swings. d) safety procedures to be followed during lifting and placing of the panels.  When panels are lifted with the rigging equipment, it must be in view of the crane operator & dogman  All personnel must be outside of the loading and drop zone  No personnel should position themselves under a precast element  Minimum of two braces must be connected before lifting  Unless specified by the project design engineer, there should be no  less than two connections to support each precast elements  No braces should be connected to another panel unless specified on the shop drawings  Review of weather and ensuring that when wind is present no panels should be lifted. 4. List the industry professionals that would be required to be consulted for some aspect of the design and construction of this building.
