CPCCBC5005A: Assessment 4 What you have to do Complete two of the following three parts (i.e. complete Part 1 and Part 3, or, complete any other combination of two parts). Do not complete more than two parts as any additional parts submitted will not be marked. This is an ungraded assessment, and your submission will be assessed as Competent or Not yet competent When doing this assessment make any assumptions you need, but be sure to state what you have assumed at the beginning of each part of your assessment. Most Parts of this Assessment relate to the following Project: 19735 Project Medium Rise Apartments Job Address: 2135 The Boulevard, Strathfield, NSW Job Title: Proposed Commercial and Residential Development Client: AKM Developments Architect: Olympic Designs, 55 Olympic Pde, Homebush, NSW You should obtain the following documents for the job, from the Learning resource tab for the unit on the OLS: Plans: 16 pages Bill of Quantities: 6 pages Specification of Works: 60 pages Task Part 1 Assume you are the site manager in charge of the construction of the Strathfield apartments with the above documentation, and that it has been decided to use AS4000 as the standard form contract for the project, and AS4901 as the subcontract. Obtain a copy of AS4000 & AS4901. You can download a copy from Saiglobal using the online TAFE library access method described on the OLS Course information page. Also obtain the construction schedule for the project - this was provided in the assessment for unit CPCCBC5002A – refer to the OLS Assessment information link for the unit if you need a copy. • Review the collected documents, and identify what subcontractors you need to build the project. LA018492 Assessment 4 CPCCBC5005A Ed 1 1 © New South Wales Technical and Further Education Commission, 2014 (TAFE NSW – WSI), Version 1, October 2014You need to familiarise yourself with the project to do this. This involves inspecting each plan briefly – as a minimum inspect each plan for a minute or so initially to see what it contains, and the general arrangement. Also briefly review the BoQ and specification. a. Prepare a list of subcontracts that you will need for the project, and then order the list into your preferred construction sequence. Use this list to create a call forward sheet for the project which you need to submit for marking. A call forward sheet template is provided in the Assessment information link. Determine and show on the call forward sheet the work day number that each contractor is required to commence on site - i.e. Day 5, Day 20 etc. - do not use dates. Also assume that work starts on site on Day 1. Clearly describe on the call forward sheet what items of work this contractor is to do. When determining the subcontractors required, make sure you identify any requirements for specialist skills, requirements or competencies, and note these on the call forward sheets. Do not fully complete other aspects of the call forward sheet. b. Use all relevant information you have collected to develop a formal organisation layout for the project – this should show how you would structure the labour on the project and include both labour for direct employees and subcontractors. Note your structure needs to conform to requirements of AS4000 contract conditions, and should assume that the principal will supply plans and specification but not a Bill of Quantities to the contractor (AS4000 Clause 8.3) A simple example management structure for a project that includes both design and construction is shown in Figure 1 below. c. Prepare a list of special conditions of contract that you would want to use with subcontractors on the project. Assume that you intend to use AS4901 as your subcontract generally on the project. (AS4901 is a companion document specifically prepared to be compatible with AS4000.) Consider whether to include or omit for example coverage in the following areas: • WHS • Environmental planning • Industrial relations • Co-ordination of works • Quality • Prior works • Protection of works • Programming i.e. clause 33 of AS2545 • Dispute resolution • Services to be provided by contractor in relation to materials handling, crane, man and material hoist, toilet facilities and power and on which level. i.e. is Subcontractor responsible for unloading trucks, and the provision of any site sheds etc. • Back charges • Insurance • No further claims clauses – i.e. at the end of job, or within 21 days or forfeit • Contractors right to dismiss – i.e. contractor retains the right to dismiss employees from site for reasonable cause, or for any cause the builder considers reasonable, or at the builders discretion, with a requirement for arbitration, and whether to include safety, non-performance etc. • Novation or assignment of subcontract • Contractor power to vary or omit works – i.e. contractor can vary • Essential services certificates – i.e. subcontractor to provide essential services certificates for work completed prior to any termination • Prior work - i.e. the subcontractor is deemed to accept the adequacy and completeness of the prior work as soon as he commences work on the prior work, and make no claims for variations for the inadequacy of prior work. 2 LA018492 Assessment 4 CPCCBC5005A Ed 1 © New South Wales Technical and Further Education Commission, 2014 (TAFE NSW – WSI), Version 1, October 2014(i.e. subcontractor can issue non-conformance certificates as part of their QA process. • Termination for convenience d. Submit each item above to complete this part, namely submit Items a, b & c being the call forward sheet, and formal contractor / subcontractor structure, and the special conditions of contract for this part of your assessment.

You are to assume that you are the Project Manager for the multi storey unit development and your program requires you to let the subcontract for CONCRETE and FORMWORK for the project urgently. You elect to use a Dincel reinforced concrete wall system instead of basement block walls shown for its speed advantage. You have received the attached four (4) quotations from the purchasing officer for the works. Analyse and compare these quotations by comparing them with your original tender budget for this work and decide which is the most cost and time effective so that a sub contract can be raised. All the subcontractors have successfully done work for your company previously and are deemed equally proficient as each other to effectively carry out the specified works. Liquidated damages on the project are $4,500 per day. Builder's site O/H costs are $2,000 per day. Assume all activities are programmed on the critical path. Use the following tender budgets for your comparison.

Prepare a subcontractor pre award interview template that you can use when assessing and comparing the merits and suitability of lowest tenderers. Many companies include in their subcontracting procedure a requirement that the lowest 2 tenderers are interviewed. The template is to be used to record the interview and determine whether the subcontractor has allowed for all work needed. It should include adequate coverage of the following areas: • General contract, special conditions and pricing • Suitability (licencing, insurance, supervisors, number of workers, financial, other projects etc.) • Programming (working week length, start & finish dates etc.) • Insurance (kinds, currency and policy numbers etc.) • Code of Practice compliance • Safety • Quality assurance • Ancillary, incidental and contractual items, and builders work with the trade (i.e. crane, hoisting, storage, penetrations.) • Schedule of facilities/services/plant and whether supplied by builder or tenderer • Payment conditions • Authorised parties signatures f. Prepare a procedure (that is a brief written description of requirements) and a template for the selection of subcontractors not currently on the company books Make sure you include the selection criteria to be used, how to gather information about previous work history, and requirements for qualification, licence and credit checks. g. Describe the communication process to be adopted and used by subcontractors on the site i.e. printed or electronic, mail or web based, site meetings, etc. to facilitate document distribution, access, retention, verification and checking of communications h. Prepare a procedure (that is a brief written description of requirements) and templates for use in the performance management of subcontractors. You should consider and include in the procedure the following 2 (two) aspects: • How to deal with poor subcontractor performance. Outline steps you would take to conduct a performance interview with a subcontractor about unsatisfactory work quality, speed of work etc. Include key questions you would ask, activities you would include in any action plan, and details of the monitoring you would undertake to ensure that poor performance does not happen again. Explain which staff you would interview to investigate the poor performance. Provide a template for use to record a meeting about unsatisfactory performance under the contract and record agreed solutions. • How to evaluate and record and summarise overall subcontractor performance on completion of the work. The procedure can state who should evaluate performance i.e. job supervisors/site managers and the items to be considered. Also provide a template for use to record the evaluation. Areas you could consider in the overall performance evaluation include time, cost, quality, environmental, WHS, personnel, industrial relations and similar parameters. Include a place on the template to record a recommendation whether to reuse. Will the outcome be disclosed to subcontractors? i. Prepare an outline of items to be explained at the site induction of contractors on the project, including any commencement forms and paperwork that would need to be completed.
