General Lighting Cnstructin Manual RSC14 UDC Prject Management specificatin RSD01 UDC Design specificatin RSC06 UDC Main Specificatin RSC07 UDC Civil Wrks specificatin RSC08 UDC Electrical Wrks specificatin RSC09 UDC Hrizntal Directinal Drilling specificatin RSC10 UDC Electrical Testing specificatin RSM01 UDC Materials specificatin RSM02 UDC Cmpatible Materials Listing specificatin The Ergn Energy distributin business has a primary fcus n meeting the increasing demands f ur custmers, regulatrs and sharehlders in relatin t ur electricity netwrk. This wrk includes the implementatin f significant prgrams t imprve the quality and reliability f electrical supplies acrss reginal Queensland. In ne such prgram Ergn Energy allws develpers t undertake design, prject management and cnstructin f the Electrical Reticulatin fr UDC Develpments. This bjective is achieved if all the prducts and services used in the Ergn Energy netwrk cnfrm t technical, quality and ther requirements defined in the relevant specificatins. Ergn Energy s DD&C Wrks mdel relies n a frmal Cntractr rating recrded n the Apprved Supplier Register. The Cntractrs listed n the Register have been rated A, B r C, as a result f an evaluatin in three areas: Quality Management System, Capability, and Perfrmance and Experience. A Cntactr s rating applies specifically t ne f the three functins: Design, Prject Management r Electrical Cnstructin. A Cntractr may be rated fr mre than ne functin. 2. APPROVED SUPPLIER REGISTER (ASR) Ergn Energy maintains an Apprved Supplier Register f Cntractrs wh have been assessed, accepted and rated by Ergn Energy as suitable fr undertaking the DD&C Wrks. Develpers must chse a Cntractr frm the Apprved Supplier Register t undertake the design, prject management and cnstructin f the DD&C Wrks. The Develper will be respnsible fr directly engaging Cntractr/s. The Apprved Supplier Register will cntain details f the Cntractr s quality system, capability and perfrmance, and recrds f Cntractr Ratings. Any Cntractr r sub-cntractr engaged in respect f DD&C Wrk must be frm the Apprved Suppliers Register r therwise apprved by Ergn Energy Standards As a general guide, a quality system like AS/NZS ISO 9001 is required where the specificatin prvides fr new, prven r mdified designs. Accrdingly, this is the crprate standard used by Ergn Energy. The specificatins are available n the Ergn Energy website Requirements fr Advertising/Prmtin Check this is the latest versin befre use Page 3 f 11 WR000902R100 Ver 2 Ergn Energy Crpratin Limited ABN Ergn Energy Queensland Pty Ltd ABN

6 A Cntractr must submit t Ergn Energy in writing, a request fr apprval f any advertising r prmtinal material that states the Cntractr is an Ergn Energy quality assured/rated prvider r in any way assciated with Ergn Energy. The Cntractr is nt t use the Ergn Energy brand (lg) withut the prir written cnsent f Ergn Energy. 3. QUALITY ASSURANCE (QA) RATING 3.1. Eligibility The Develper must select a Cntractr frm the Apprved Suppliers Register r cntract Ergn Energy t cmplete the DD&C Wrks. The Cntractrs listed n the ASR have been rated by Ergn Energy as a result f an evaluatin in three areas: Quality Management System Capability; and Perfrmance and Experience. Only rated Cntractrs r Cntractrs wh have therwise been apprved by Ergn Energy will be eligible t execute cntracts fr DD&C Wrks which when cmpleted are t be cnnected t the Ergn Energy netwrk. The Cntractr/s will be cntracted t a Develper fr this wrk. Cntractrs are rated t prvide the relative level f quality assurance t Ergn Energy and the custmer. Ratings are valid fr a perid f 2 years and within that perid the Ratings may be mdified fr perfrmance nly. A frmal re-rating may be requested by either Ergn Energy r the Cntractr due t sme imprvement r change by the Cntractr, r as a result f bserved perfrmance (see belw). Any change in the Cntractr s Rating will stand until, in the pinin f Ergn Energy, there is demnstrated evidence that the cause f the change has been eliminated and perfrmance is satisfactry. Ergn Energy may call fr a registratin f interest fr Cntractrs wishing t be cnsidered fr the Apprved Suppliers Register. Prspective Cntractrs may, hwever, request t be added t the Apprved Suppliers Register at any time. Ergn Energy may chse t implement a fee schedule which cvers the cst f cmpleting a Cntractr Rating. The Cntractr s Rating will be assessed n the basis f the fllwing table: Supplier Ratings Cmpnent Max Pints Quality Management System 80 Capability (t prvide the required service) 70 Perfrmance and Experience 100 Maximum Scre 250 A Cntractr with n relevant Ergn Energy perfrmance data fr assessment may cmmence with an initial scre f 65 fr perfrmance Calculatin The Cntractr s quality assurance system will be evaluated n the basis f infrmatin prvided by the Cntractr. A scre will be determined fr each f the three cmpnents listed in the table abve. A Rating will be determined by the additin f the scre fr each f the three cmpnents, and by reading the applicable Rating frm the fllwing diagram: Check this is the latest versin befre use Page 4 f 11 WR000902R100 Ver 2 Ergn Energy Crpratin Limited ABN Ergn Energy Queensland Pty Ltd ABN

7 Calculatin f the Rating: Obtain ttal scre frm assessment f Quality Management System, Capability and Perfrmance. Read diagram (abve) e.g. Scre f 180 determines Cntractr is C rated. Any raw scre achieved will be runded dwn t next increment n scale, e.g. Scre f 199 will g t 195. Rating bands are as fllws A Rating cmmences frm a scre f 225 B Rating cmmences frm a scre f 185 C Rating cmmences frm a scre f 145 A Cntractr may appeal t Ergn Energy s panel manager fr a review f its Rating. The Cntractr must nminate a representative with respnsibility fr liaisn with Ergn Energy n quality matters. The nminated representative will have authrity t initiate apprpriate changes relating t quality system requirements, standards, quality perfrmance and ther matters. The Rating will nly be made available t the Cntractr and t thse Ergn Energy persnnel wh require knwledge f the Cntractr s Rating fr the assessment and management f ffers, cntracts and ther services. 4. MONITOR ASR RATING 4.1. Rating Perid The frequency f Rating reviews will be as fllws: Fr the initial Rating, there will be ne review allwed within 3 mnths f the initial evaluatin. There will be n charge fr this review. Hwever, a fee, based n the cst f a field audit fr a B rated Cntractr (refer t the UDC Develper Handbk), may be charged fr subsequent visits. This fee decisin is t be taken by the panel manager and will be advised t the Cntractr prir t the visit.

8 Ratings will be reviewed every 2 years (based n an assessment f Quality Management Systems, Capabilities and Perfrmance). On a quarterly basis, the panel manager reviews the cllated minr nn-cnfrmances recrded during perfrmance audits which were cmpleted in that year. A reprt t the Cntractr will result if there is a significant change t the Cntractr s Rating. A review f the Rating will be cnducted annually with a rating review letter sent t each cntractr. Rating reviews will nt be undertaken within 3 mnths f a previus review unless a majr nn-cnfrmance has ccurred within the perid. If a Cntractr has nt been awarded a cntract within 2 years f receiving an initial Rating, then the Rating may lapse. If a subsequent Rating is requested, perfrmance assessments prir t the 2 year perid will nt apply and the Cntractr may receive the standard perfrmance allcatin f 65 pints unless referee reprts prvide adequate additinal infrmatin. If a Cntractr is issued a Rating with a 65 entry perfrmance scre, a perfrmance review will nt be cnducted until after the cmpletin f the first full quarter. A review f Develper Design & Cnstruct plicy and dcumentatin will be cnducted annually, unless there is a legal imperative Rectificatin f Nn-Cnfrmances If nn-cnfrmances are identified, it is the respnsibility f the Cntractr t submit t Ergn Energy a plan fr immediate rectificatin f such deficiencies. The Cntractr is required t shw evidence f any cmpleted crrective actins. If crrective actin is nt taken prir t the cmpletin f the prject, Ergn Energy is unlikely t accept the cmpleted wrk Reward fr Perfrmance As stated abve, the cmmercial and cntractual terms between a Develper and the engaged Cntractr/s will be the respnsibility f the parties invlved. Circumstances may arise where a pr perfrmance has elicited penalties under thse cntractual arrangements. Irrespective f that actin, pr perfrmance will affect the rating fr the Cntractr. Areas f cnsideratin fr the perfrmance evaluatin may include thse f technical, safety, envirnmental, custmer service and industrial matters. An infringement in perfrmance may result in a cmbinatin f the fllwing actins: issue f a defect ntice; warning fr pr perfrmance; the deductin f pints frm the Cntractr s perfrmance scre, which culd affect the Cntractr s Rating; review f the Cntractr s Rating; suspensin f the Cntractr s Rating; r withdrawal f the Cntractr frm the Apprved Supplier Register. The severity f the penalty will relate t the severity f the infringement. A successfully cmpleted prject culd result in a bnus under cntractual arrangements between a Develper and the engaged Cntractr(s). Even s, the gd perfrmance will affect the Rating fr the Cntractr. The areas f cnsideratin fr the perfrmance evaluatin are the same as thse cnsidered in the previus sub-sectin. A gd prject result may result in a cmbinatin f the fllwing actins: issue f a letter f cmmendatin; additin f pints t the Cntractr s perfrmance scre; and review f the Cntractr s Rating.

9 4.4. Applicatin f the Glf Handicap Apprach At the initial Rating f a Cntractr the Cntractr is assigned a scre fr its quality management system, its capability and its perfrmance. Let us assume the scres are as fllws: 60, 55, 70. The ttal (185) is cnverted t a rating. The Cntractr is a B rated Cntractr. In its first DD&C prject the Cntractr is audited by Ergn Energy. Three nn-cnfrmances are detected and remedied. The result f the audit is frwarded t the panel manager f the Apprved Suppliers Register. A pr audit result is defined as ne r mre nn-cnfrmances. The panel manager ntes the pr audit result and adjusts the perfrmance scre dwn by 5 pints. The ttal scre is nw 180 s the Cntractr s Rating is nw C. Currently, the Cntractr is engaged n its secnd UDC prject. The Cntractr is advised f the dwngrade which applies immediately. The increase in any audit csts applies fr the next prject. The Develper f this secnd UDC prject will nt be financially disadvantaged during this prject. Tw gd audit reprts will see the Cntractr rating advanced by 5 pints and it becmes a B. This is a significant incentive fr the Cntractr. A psitive result scres nly 2.5 pints because this is the result which is expected and desired. 5. CONTROL RATING 5.1. Intrductin The Electrical Reticulatin f DD&C Wrks is t be designed and cnstructed in accrdance with the quality standards and perfrmance requirements f Ergn Energy nw and int the future. Develpers may chse Ergn Energy r a single Cntractr r individual Cntractrs wh will facilitate r undertake all r sme f the fllwing functins: Design this Cntractr is respnsible fr prducing the design f the Electrical Reticulatin and public lighting fr the prpsed Develpment.

10 Develpers are t select their preferred Cntractr frm the Apprved Suppliers Register. The Develper may als nminate a Cntractr nt n the Register. If the nminated Cntractr is nt n the Register they must underg the prcess f btaining registratin befre they can cmmence wrk. The selected Cntractr/s must hld and maintain a Rating n the Apprved Suppliers Register fr ne r mre f the three functins f design, prject management and electrical cnstructin Rating Evaluatins - Prject Managers The cnstructin f DD&C Wrks is t meet stated quality standards and perfrmance requirements. It is imprtant that these wrks are cnstructed t Ergn Energy s standards s there are minimum future maintenance prblems and interruptin t custmers. This can be achieved by ensuring that the cnstructin cnfrms t Ergn Energy s standards and stated requirements. As such, the cmpleted electrical infrastructure must be effectively prject managed. Ratings will be issued fr the prject management f electrical cnstructin fr DD&C Wrks. The respnsibilities f a prject manager are defined in the accepted principles f prject management. A Prject Manager s QA evaluatin is based n the standard prcess fr Cntractrs, as fllws: Quality Management Systems Evaluatin - This evaluatin will be based n the submissin f a Quality Systems manual and an assessment f the Cntractr s Management Systems. Maximum management system pints will be allcated where a cnsultant has current third party certificatin (by a natinally accredited audit rganisatin) t AS/NZS ISO 9001:2000 which includes the apprpriate scpe f wrk. Capabilities will be evaluated fr the cmpany, and maximum pints are awarded if all the key prject management persnnel are certified. The fllwing issues are cnsidered: apprpriate tls and cmpetencies as identified in the AQTF fr prject management; the number f staff qualified 1 at AQTF Levels 4 and 5 in prject management; the number f staff prfessinally certified 2 in prject management; and demnstrated supervisin capability. The determinatin f the perfrmance scre will initially will be based n the histrical perfrmance f the cmpany. The perfrmance scre nce registered will then be based n the perfrmance f the cmpany with a scre using the fllwing: The results f the cnstructin Cntractr perfrmance evaluatin fr the Develper s prject [50%]; and The prject management utputs fr Electrical Reticulatin wrks: Cmpliance t design; As cnstructed drawings; Cmmissining prcedures; On site audit results; Rectificatin f defects; Materials used; and Test results. 1 Qualified at Level 4 r 5 means a Certificate IV r a Diplma in Prject Management. 2 Certified at Level 4 r 5 means the individual is a Qualified Prject Prfessinal (QPP) r a Registered Prject Manager (Reg PM) with the Australian Institute f Prject Management (AIPM) r the Prject Management Institute (PMI).

11 5.3. Rating Evaluatins - Design Evaluatins fr design cnsultants are based n the standard AS/NZS ISO 9001:2000: Quality Management Systems Evaluatin - This evaluatin will be scred the same way fr prject management, design and cnstructin cntractrs. Capabilities Evaluatin - Capabilities will be evaluated based n the fllwing: the number f persnnel qualified t use, r experienced in use f, apprved design tls; qualified persnnel authrised t apprve electrical designs; the availability f apprved design tls; familiarity with Ergn Energy s design requirements; capacity t exchange sft cpy design files; and the submissin f a design capability test, as required, fr evaluatin. Perfrmance - The initial determinatin f the perfrmance scre subsequent audit results will be based n an evaluatin f submitted designs which will include the fllwing factrs: general design and schedules; cmmissining plan; apprvals; labelling, prfiles; and vlt-drp calculatins Rating Evaluatins Electrical Cnstructin Evaluatins fr cnstructin cnsultants are based n the standards (refer References sectin). Quality Management Systems Evaluatin - This evaluatin will be scred the same way fr prject management, design and electrical cnstructin cntractrs. Capabilities will be evaluated fr the cmpany, and maximum pints are awarded if the cmpany wns its wn equipment and its emplyees hld all the apprpriate qualificatins fr the electrical cnstructin wrk. The fllwing issues are cnsidered: the availability f the tls and equipment required fr the executin f the tasks described in the standards; (refer References sectin), the number f emplyed staff with the apprpriate qualificatins; and rganisatinal capacity t absrb the cnstructin wrk. Perfrmance If an initial perfrmance scre cannt be determined a standard value f 65 is awarded. Otherwise, the initial evaluatin f the perfrmance scre and subsequent audit results will be based tw areas f assessment: The results f the cnstructin Cntractr perfrmance evaluatin fr cmpleted prjects; and The usual deliverables frm UDC wrks: prcess and final prduct audit results; design cmpliance; labelling cmpliance; use f ecnmical cmmissining prcedures; signed ff hld pints fr cnduits; and prject success Check this is the latest versin befre use Page 9 f 11 WR000902R100 Ver 2 Ergn Energy Crpratin Limited ABN Ergn Energy Queensland Pty Ltd ABN

12 6. PRINCIPAL CONTRACTORS WHO USE SUB-CONTRACTORS AND/OR SPECIALIST CONTRACTORS 6.1. Methdlgy All principal Cntractrs must have a rating (refer sectin 1.1) and the principal Cntractr is able t engage sub-cntractrs as an extra resurce, if required. Fr auditing purpses the principal Cntractr must ntify Ergn Energy prir t any sub-cntractr being engaged and apprval given befre the sub-cntractr cmmences wrk. Any nn-cnfrmances fund will affect bth the principal and sub-cntactrs Rating (refer sectin 4.4) Specialist Cntractrs Specialists refer t sectrs f the trade where there is a shrtage f suitable tradespersns in specialised fields, such as in this case f HV cable jinting. The specialist will have the rating f the cntractr requiring the specialist resurce under the Apprved Suppliers Register (i.e. in relatin t the three criteria Quality Management System, Capability and Perfrmance). The specialist will be attached t the principal Cntractr fr cable jinting wrk. If there are any changes t the cable jinter s status then the Cntractr is t ntify and prvide Ergn Energy with the details f the new specialist including references t cnfirm quality f prduct and perfrmance. If references can nt be substantiated, Ergn Energy will be required t witness the first cable jint being cmpleted by the specialist fr quality f prduct at n cst t Ergn Energy. The specialist will then be a department f the principal Cntractr and be subject t the final cmpliance audit in relatin t his perfrmance and managed accrdingly. In Develper Design & Cnstruct cnstructin HV cable jinting is the nly field listed as specialised with Ergn Energy. 7. CONTRACT NON-CONFORMANCE 7.1. Nn-Cnfrming Wrk All nn-cnfrmances will be itemised by Ergn Energy persnnel n an apprpriate assessment checklist. A reprt n the assessment results will be prmptly frwarded t the Develper. The Develper is required t rectify, at its expense, all the listed defects within a specified time. Ergn Energy reserves the right t rectify the defects at the Develper s expense if the Develper is unable t attend t the rectificatin/s in a timely and acceptable manner, r the Develper des nt satisfy Ergn Energy s specified requirements. Each audit is analysed and an audit analysis is prepared. The analysis cllates all f the audits cmments int ne f fur categries: Prduct usually the surce f any majr nn-cnfrmances Management Dcumentatin and Rectificatin Safety These fur categries make the link between the audit checklist and the elements f the Cntractr s rating, as fllws: Check this is the latest versin befre use Page 10 f 11 WR000902R100 Ver 2 Ergn Energy Crpratin Limited ABN Ergn Energy Queensland Pty Ltd ABN

13 Any nn-cnfrmance may be raised by Ergn Energy persnnel during a visit r audit. The defect will be recrded as a majr r minr nn-cnfrmance. Subsequently, the defect will be cmmunicated in writing t the Develper. If Ergn Energy is required t rectify any nncnfrmance, Ergn Energy will recver the cst frm the Develper. 8. CONCLUSION The cmmercial and cntractual terms between a Develper and a Cntractr are the respnsibility f the parties invlved. The cntractual relatinship mdel fr prjects undertaken by Cntractrs engaged directly by a Develper is supprted within the Develper Design & Cnstruct initiative. Only Cntractrs registered n the Apprved Suppliers Register are authrised t perfrm DD&C Wrks. If a Develper wishes t use a specific Cntractr wh des nt have a rating, the unrated Cntractr is t apply t the Panel Manager wh supervises the Apprved Suppliers Register. Once rated, the Cntractr is respnsible fr maintaining r imprving the Rating. This invlves maintaining cmpliance with all f the requirements f a Cntractr n the Apprved Suppliers Register, including actin t ensure the currency f certificates, maintaining wrk place health and safety and envirnmental prtectin cnditins in respect t perfrming wrk that cmplies t Ergn Energy requirements.
