6. Competent person details A competent person for building work, means a person who is assessed by the building certifier for the work as competent to practice in an aspect of the building and specification design, of the building work because of the individual’s skill, experience and qualifications in the aspect. The competent person must also be registered or licensed under a law applying in the State to practice the aspect.
If no relevant law requires the individual to be licensed or registered to be able to give the help, the certifier must assess the individual as having appropriate experience, qualifications or skills to be able to give the help.
If the chief executive issues any guidelines for assessing a competent person, the building certifier must use the guidelines when assessing the person.

Refer to Geotechnical investigation reportno. J18/01 by Wagner Soil Testing(07) 5496 6715.
Excavate to firm, dry, inorganic ground andmaintain the excavation in a stable condition.
Compact the subgrade below slabs andfootings to 98% dry density ratio (standardlaboratory compaction). Refer AS3798.
UNO all fill is to be general fill materialhaving a CBR not less than 15%. Spreadfill in maximum 200mm layers (loose) andcompact to 98% standard (AS1289).
Founding material shall be approved by aGeotechnical Engineer, engaged by thecontractor, before footings are constructed.
Bored piles are to be found in natural stiff sandyclay and are to have an allowable bearing capacityof at least 100 kPa. Bored piles are to have a min600 socket into the founding material.
Where any kind of excavation will underminea 45° line of influence extending from thebase of any footing, approval shall besought from the geotechnical engineer.

Reinforcement shall not be modified, weldedbent, lapped or spliced other than as shownon these drawings without the Engineer's approval.
Use bar chairs, spacers and support barsto hold reinforcement in correct positionduring placing of concrete. Materials for suchsupports must suit the exposure conditions.
The engineer shall be invited to inspectthe work after reinforcement is placedand before concrete is cast.

DC1 Structural elements are designed inaccordance with AS1170.2 using thefollowing loading parameters.
Steel cast in concrete Hot dipped galvanisedwith Durebild STE from70mm below the finishedconcrete surface.
Prepare all surfaces to manufacturerspublished recommendations. Ensurecompatibility with finish coats.
Designer's statementThe cabin foundation comprises of pilesconnected to steel posts which suspendthe cabin slightly above natural ground level.
The piles are to be bored piles with minimumreinforcement and a minimum depth of 1.2m.All piles are to be bored through any uncontrolledfill found and have a min 600 socket into thesuitable founding material as noted in thegeotechnical report.
The lateral resistence of the foundationsystem is designed to have a couplingeffect to resist overturning moments fromwind loads.
The 56 day drying shrinkage shall not exceed 850µ
Production assessment results for all concrete castshall be submitted to the Contract Administrator forapproval.
All concrete is to be in accordance with AS3600.
If construction joints are required other thanthose shown on the drawings, the locationand detail is to be approved by the Engineer.
Cure concrete for 7 days by sealing with asheet, impervious to moisture.
Slab andfootings
C1
Compact all concrete with a needle vibrator.
Concrete slabs are designed in accordance with thefollowing exposure classification:
At least 14 business days before orderingany structural prefabricated elements, thecontractor shall submit a complete set ofcoordinated shop drawings to the ContractAdministrator for review by the consultants.
Structural prefabricated elements shallinclude but not be limited to steelwork.
Where prefabricated elements requiretemporary supporting structure, thecontractor shall include the relevant detailwith the shop drawing submission. Any suchsubmission does not relieve the contractor oftheir responsibility as stated in note G4.

Prefabricated Elements
Piles and Footings A1
External and internal steel is to have a minimumthickness of 0.5mm each and a grade of Q235Bwhich is equivalent to the international standardcarbon steel grade, ASTM A36.
Adhesive between steel sheet and expandedpolystyrene to be fully bedded over pan ofroof sheet profile with an equivalent shearstrength and out of plane adhesion of no lessthan 0.30 MPa.
Panels and their immediate connection shallbe designed by the manufacturer to resist theloads as described on drawings S1 (includingnote DC1).
Where any assembling, cleaning and maintenance ofwindows, walls, roof and other components of the cabinwill require persons to be situatied where a fall from aheight is in excess of two metres, scaffolding, fallbarriers or Personal Protective Equipment (PPE) shouldbe used in accordance with relevant codes of practice,regulations or legislation.
SD2.2 Slippery or uneven surfacesSpills, loose material, stray objects or any other matterthat may cause a slip or trip hazard should be cleanedor removed from access ways. Contractors should berequired to maintain a tidy work site during constructionof the cabin. Materials for assembly and constructionshould be stored in designated areas away from accessways and work areas.
Components with a mass in excess of 25kg shouldbe lifted by two or more workers or by a mechanicallifting device.
Construction of the cabin foundations will requireexcavation and installation of items within excavations.Where possible, installation should be carried out usingmethods which do not require workers to enter theexcavation. Warning signs and barriers to preventaccidental and unauthorised access to all excavationsshould be provided.
SD3 Operational use of cabinThis cabin has been designed for residential use. If it,at a later date is used or inteded to bee used as aworkplace, the provisions of the Work Health and SafetyActs 2011 or subsequent replacement Act should beapplied to the new use. In such a case, the building certifiershould be consulted. A structural engineering assessment isrecommended.
SD4 Other high risk activity
These notes must be read and understood by all involved in the project.This includes (but is not exclusive to): owner, builder, sub-contractors, consultants, operators, maintainors and demolishers.
Possible foundation construction sequence
The following construction sequence is given to demonstrate the viability of the design as presented.With the exception of the case where the structural engineer is engaged to review the contractor'sdetailed plans for the execution of work, the following sequence does not relieve the client orcontractor of any obligations as designers of structures or persons responsible for workplace inaccordance with the Workplace Health and Safety Act (QLD).
1. Excavate bored piles to suitable founding material.
2. Place bored pile reinforcement.
3. Cast bored piles.
4. Cast footings and concrete ground slab
5. Erect steel posts with anchors connecting base plateto bored piles. Survey post to ensure post is plumb.
6. Weld steel bearers onto post.
7. Where applicable, refer to the following cabin construction sequence drawings.
Welding of existing hot dipped galvanised materialwill result in a release of zinc oxide fumes that arepotentially harmful. All persons on site should ensureadequate ventilation and wear Personal ProtectiveEquipment including protection against inhalationwhile welding is carried out.
Substances such as glue, solvents, spray packs,paints, varnishes and some cleaning materials anddisinfectants may have dangerous emissions. Areaswhere these are used should be kept adequatelyventilated while the material is being used and for aperiod of installation. Personal Protective Equipmentmay also be required. The manufacturer'srecommendations for use must be carefullyconsidered at all times.
SD2.3 Safe access and movementObstructions on site may introduce hazards. Theseobstructions may include elements constructed earlierin the construction sequence.
All electrical work should be carried out in accordance withCode of Practice: Managing Electrical Risks at the Workplace,AS/NZ 3012 and all licensing requirements.
All work should be carried out in accordance with Codeof Practice: Managing Noise and Preventing Hearing Lossat Work. Noise sources may include but are not limited to:cutting of steel elements including reinforcing bar, use ofpower of pneumatic tools.
