3MLT-10 Deployment Trial Background

8

The Melton 10 (3MLT‐10) Deployment Trial was initiated by NBN Co to create an internal baseline/benchmark for programme, productivity and cost performance utilising:

1. The Render deployment management system;

2. Innovative specified equipment;

3. Innovative build methods and work practices;

4. Project governance initiatives; and

5. Build Drop installation during LN/DN build.

Telstra remediation works commenced in January 2014. NBN Co engaged Australian Broadband Company, Celemetrix, Comms Connect and Linktech directly to carry out the works with a uniform Schedule of rates. Specified equipment was free issued by NBN Co to the Contractors.

3MLT‐10 is a large residential FSAM with 2484 GNAF’s (2459 SDU, 25 MDU). It contains a mixture of old and new infrastructure and is a rocky area. There is also a relatively large number of 5 and 1 acre lots and standard residential blocks within the FSAM.

The 3MLT‐10 deployment was the first to utilise a Telstra FIR / NBN Co design. A separate Post Implementation analysis for Design is currently being completed by NBN Co’s Design group.

•Architecture 2.1 • Step Change •Melton Project & Render •New Technology Introduction

• Small Form Factor Multiport • Smaller Diameter Cables • Next Generation FDH


Why have we chosen Type 2.1 Architecture?

Two main reasons: • To Reduce cost • To Reduce the time taken to build the network.

Savings are made in:

• Materials used • Civil works

• Pit Upgrades • Duct Augmentation • Duct Build.

Redesigns will: • Reduce the cost of the build • Get designs built faster, connecting more premises by target dates

Architecture 2.1

New


Architecture Type 2.1 Key Changes

• Allocated Fibres at each Demand Point reduced to: o 1.5 fibres per Single Dwelling Unit (SDU) - Type 2 was 3 fibres o 1.5 fibres per Commercial Premises - Type 2 was 2 fibres o 1.25 fibres per Multi Premises Site (MPS) - Type 2 was 1.5 fibres

• Connected Fibres at each Demand Point has not changed: o 1 fibre per Single Dwelling Unit (SDU) - Type 2 was 1 fibre o 1 fibre per Commercial Premises - Type 2 was 1 fibre o 1 fibre per Multi Premises Site (MPS) - Type 2 was 1 fibre

• Double the utilisation of each Fibre Distribution Hub (FDH) to approximately 400 addresses

• Reduce feeder fibre allocation per FDH to 24 fibres (2 ribbons)

• Reduce default Distribution feeder cable size from 576 fibre to 432 fibre


Architecture 2.1 Benefits

Approved for implementation: • Reduction in the fibres allocated per premises at the Multiport • Reduction of DSS fibres allocated per FDH • Relaxation of the DSS protect path rules • Slight reduction of the Mandrel size • Introduction of Small Footprint Multiports (SFM)

Reduction in fibres means: • Smaller cables, so they are more likely to fit into existing ducts • Fewer FDH cabinets, so better chances of finding good sites • Fewer splices, so they are more easily placed into existing pits or manholes • Still have plenty of capacity for growth (Typically four fibres spare in each Multiport tether cable)

Mandrel size reduction is closer aligned to the real world and reduces augmentation.

Small Footprint Multiports fit into most existing pits.


Fibre Structure—Underground Type 2 The configuration for underground local fibre is a ‘Star’ local access joint used to provide the multiport tethers from a central pit, feeding pits located at the property boundary containing multiport terminals utilised to provide the same ‘plug and play’ connections.

100% SDU scenario


To determine the impact of reducing the fibres allocated per premises. Specifically, the impact on Duct and Pit Augmentation required. To achieve this, four areas were selected to produce designs under different fibre allocation rules and compare the theoretical build requirements based on the BoQ. Areas were selected within the following constraints: -Two adjacent FSAMs (So they could be sensibly combined) -Combined less than 5000 premises (To be able to fit into 1x FSAM) -NDDs issued within the last 6 months (To improve the input data quality) -No aerial network (Subject of a different review) -Not outliers in terms of augmentation or new build quantities

Fibre Design Changes: Update 1. Step Change Project 2. Backlog Progress

Planning & Design July, 2013


Executive Summary – Step Change Up till now...

The Issues...

What are we proposing... So that in the future...

Planning and Design completes NDDs, releases these to Construction Detailed Design, and then these are released to Service Delivery Partners to complete walkout activities and then develop Detailed Designs, co‐ordinated by Construction Regional Project Directors.

• Bottlenecks will reduce, throughput will increase and the SDP’s can focus on building the Network.

• From issuing a CI to current Gate 1, the expected cycle times will go from the current average of 86 days to


Telstra FIR & DD (as per Step Change) only goes part way to address the 2014 850k GNAF target

Page 49

June July August September October November December

• Step change improvements deliver only part of 2014 850k GNAFs target • In addition to implementing step change recommendations, improvement / process changes must also address current

inefficiencies in “NDD to DDD delivery model”. • A number of different delivery models for detailed design during transition, each with different accountabilities across the

“NDD to DDD process”. Much greater coordination across functional areas needed to achieve the corporate targets. • Staged rollout of these models will add additional complexity that could be more effectively managed with Single NBN Co

6 key improvements proposed to optimise the E2E design process


Reminder: Guiding principles will help limit number of variations, ensure constructability and efficiency

Page 51

• 1 master E2E process will be defined • Various contract models will have separate processes (if required), but they will be

based on the master process

• New process will have to ensure (via accountabilities, KPIs, feedback loops, etc.) - Schedule of FSAM designs to be aligned to POW, including prioritised

programme of FSAMs over next 12 months (planned to be 18 months) - Deliverables meet all reasonable and agreed technical expectations of

Construction. The new process will not aspire to over-deliver / over-engineer any outputs

- Clear handover accountability from Design to Construction - Efficient design correction mechanisms and feedback loops in case of design

errors (from the constructability point of view)

• Clear end-to-end FSAM ownership along the entire design process • Process cycle time targets will be based on the 80-20% rule

- Target durations will be realistic to meet in case of “business as usual” situations and exceptions

• (When we set target durations) we assume that the all required contracts/relationships will be in place to facilitate To-Be

- E.g. we won’t lose significant time in Electrical Design phase due to lack of proper cooperation with Utilities

• P&D and C have to define a mechanism ensuring that designs meet required quality levels and include details required for constructability.

• Checks to focus on comprehensiveness /quality of high impact parts

• New design process and org setup will require different level of support from the corporate functions (HR, OHS&E, stakeholder management). Required forms and volume of support to be defined

• P&D and C to define how variations will be handled efficiently • Issues will require systematic tracking to get fixed within reasonable

time and initiate continuous improvement measures within P&D

• KPIs will track quality (constructability),cycle times and costs • KPIs will have to reflect the new org and accountability structure • KPIs will have to be aligned with the overall E2E reporting concept

Pain Points

1. Poor data quality leads to NDD inaccuracies and downstream rework 6. Design guidelines and rules are constantly changing so DPs struggle to benefit from experience based efficiency

2. Utility providers are not engaging with DPs for aerial designs, resulting in delays and changes to underground 7. Construction drawings frequently don't match BOQ/BOM

3. FIR is not completed on time or to required quality 8. NBN designers spent most of their time solving ad‐hoc problems, not completing design reviews

4. Relaxed gate standards encourage DPs to continue with bad practices 9. Design optimisation is delivering results, however it causes significant re‐work

5. Constructability not sufficiently considered during DDD phase 10.

Fast tracking FSAMs and accountability gaps contribute to delays in obtaining CoA acceptance

3MLT-10 Deployment Trial Background

64

The Melton 10 (3MLT-10) Deployment Trial was initiated by NBN Co to create an internal baseline/benchmark for programme, productivity and cost performance utilising:

1. The Render deployment management system;

2. Innovative specified equipment;

3. Innovative build methods and work practices;

4. Project governance initiatives; and

5. Build Drop installation during LN/DN build.

Telstra remediation works commenced in January 2014. NBN Co engaged Australian Broadband Company, Celemetrix, Comms Connect and Linktech directly to carry out the works with a uniform Schedule of rates. Specified equipment was free issued by NBN Co to the Contractors.

3MLT-10 is a large residential FSAM with 2484 GNAF’s (2459 SDU, 25 MDU). It contains a mixture of old and new infrastructure and is a rocky area. There is also a relatively large number of 5 and 1 acre lots and standard residential blocks within the FSAM.

The 3MLT-10 deployment was the first to utilise a Telstra FIR / NBN Co design. A separate Post Implementation analysis for Design is currently being completed by NBN Co’s Design group.


3MLT-10 Scorecard for Comparison

65

Deployment data for all FSAMs ‘Ready for Service’ or ‘Build Commenced’ in the Ballarat 2 CSA (3BRA) has been used as the basis for comparison. This results in a group of 20 FSAMs for comparison.

The scorecard items below was prepared and agreed by all of the NBN Co Stakeholders prior to commencement of the trial, and was to be the basis for comparison at the end of the trial period.

3MLT-10 Render Deployment Management Results

Following a technical Proof of Concept, the Render deployment management methodology was trialled in 3MLT-10. Render was used to:

1. Automatically create the work scope, material BOQ directly from the DDD, including the asset data and construction sequence.

2. Allocate work to Contractors in advance using the work scope information created.

3. Automatically create the work schedule based on committed allocated resources.

4. Release 4 days worth of work to crews each day(top up) to ensure continuity & visibility of work.

5. Only release jobs that were ready to be done, i.e. all preceding tasks had been completed.

6. Status completed work daily then optimally reschedule the remaining work.

7. Capture as-built information at the task level on the day it was completed wherever possible, taking advantage of the detail extracted from the DDD in the task data.

8. Automatically update progress status and view scope/resource/asset/location/cost/programme data centrally, visible on Google maps.

9. Build the network as it was designed, eliminating “air gaps” and red-line mark ups.

10. Sequence and manage build drops concurrently with the LN/DN build.

The task based approach created by the Render tools took some time to become familiar to the teams after which time it was used to deploy and manage the work. There is still some work to be done on the functionality of the system however it performed well.


3MLT-10 Deployment Management Results

Reduced administration and simplify the following for NBN Co and Contractors:

Work Scope – defining scope at the task/asset/address level

Work Visibility - viewing all elements of the deployment on Google maps, from high level to task level to address level

Variation Management – measure design and in-field variations at the task/asset/resource level

Work Allocation – commit work volumes at the task level to Contractors

Progress reporting – automated, accurate and updated on a daily basis (Report 004)

Jeopardy management – manage issues at the task/asset/address/resource level

HSE & Quality management – integrated at the task/resource/asset level

Improve productivity, resource utilisation and forecast accuracy:

Schedule optimisation – automated daily schedule optimisation, accurate forecasts

Contractor productivity – ability to monitor productivity at the task/crew level

Crew utilisation – maximised productivity of resources each day

As-built management – updated as-built data accurately at the task/asset level daily


3MLT-10 Innovative Specified Equipment Results

SMALL DIAMETER CABLE

Overall indications are that SDC is 10-20% faster to deploy

Lighter and more flexible making the cable easier to handle and transport

Easy to coil (smaller layout area required) for cable directional changes during haul, greater utilisation of Telstra infrastructure

Less physical strain on crew – HSE benefit + reduction in crew number required for hauling

Significantly increased installation efficiency – 5 mins install vs. 15 minute install for traditional multiport No requirement to mount the multiport Can be used in smaller pits, reducing the need for Telstra pit

remediation which significantly reduces HSE risk associated with Asbestos Containing Material (ACM)

Quality issue with connection waterproofing is under investigation by the CTO group.

SMALL FOOTPRINT MULTIPORT


3MLT-10 Innovative Build Methods and Work Practices Results

Intelligent Optical Loss Measurement (IOLM) Testing Provided a 66% reduction in testing time Automated test result capture and upload Enabled real time defect rectification and

smoother handover when FSAM complete/less defects

Removed subjectivity regarding test results

HSE initiatives:

Safety barricading in lieu of bunting

Waste water harvesting and re-use

Distribution pipe straightener removed memory of the 100mm pipes minimising HS&E incidents

In Line Jointing:

Significantly reduces the number of splices required.

100% Asset Locating

Investment in asset locating resulted in zero asset strikes.

Non destructive potholing/Hydro Vacuum:

Ground Penetrating Radar was trialled and had mixed results impacted by the soil conditions

Use of the Sub Surface Instruments All Material Locator (AML) was an effective method of identifying buried assets

Design walkout/Constructability Review:

Joint NBN Co/Contractor constructability walkout prior to completion of the design would have eliminated many of the design variations encountered.

Purpose stocked Trailer for drops:

Engaged Kennards to trial.

Proven initial success.


3MLT-10 Project Governance Initiatives Results

Project Governance Meetings (twice a week)

Provided a forum to jointly address schedule, resourcing and jeopardy issues
