As part of our commitment to improve our relationship and communications with ASPs, Essential Energy

are holding the next round of forums. The purpose of these forums is for an ASP to come along and hear

about the latest news in the ASP space and to ask questions or raise issues with representatives from

various Essential Energy teams.

Forums will commence from 5pm at the above locations, with light refreshments available. To determine

venue sizes we would appreciate any ASPs who wish to attend complete a survey or email

aspinfo@essentialenergy.com.au with company name, ASP level, numbers attending, which forum you will be attending and anything you would like to see at our forums.

If you need further information, please email aspinfo@essentialenergy.com.au

A recent review of the dunnage supplied with our plant has resulted in additional dunnage available to meet the crane code of practice for work completed in our typical operating environment. Key risks identify:

All operators of a crane borer and the holder of a C2 or higher HRWL, should know, understand and complete the requirements for calculating the weight being borne by the outriggers and the minimum area required to safely distribute it.

The ground conditions, mass of the crane and the mass of the load must be considered. This will help determine if you need to carry extra dunnage.

The attached matrix minimum area under outrigger M2 – Crane Borer can be used as quick reference guide showing different loads, ground conditions and the required dunnage.

The equation below, taken from the Mobile Crane Code of Practice 2006 (QLD), is used to calculate the minimum area required to safely distribute the load.

0.65 x (total crane mass + lifted load)

----------------------------------------------------

maximum permissible ground pressure

Essential Energy use four types of dunnage:

Stability is critical to the safe operation of an EWP and similar to cranes outrigger ground pressure must be considered.

The attached matrix minimum area under outrigger M2 – Elevated Work Platform can be used as a quick reference guide showing different vehicle operating weights, ground conditions and then required dunnage for EWPs.

Essential Energy would like to share this information and advise that we are using the Mobile Crane Code of Practice 2006 (QLD) for work completed in our typical operating environment.

Essential Energy have been made aware on several occasions where designs have been completed by Level 3 Accredited Service Providers (ASPs) as a desktop only design and no site inspection has been undertaken. Level 3 ASPs are reminded that as per CEOP2015 General Terms and Conditions for Contestable Work –

Level 3 ASPs are to ensure site inspections are undertaken and all information and documentation is correct prior to the submission of the design and subsequent construction by the Level 1 ASP. Completion of the Environmental Impact Assessment REF Worksheet (CEOF1070.02) for any project requires a declaration on page 18 to be completed acknowledging that, the person completing the document has visited the site prior to the commencement of the proposed works.

The Design Information Package template is currently being updated to provide information regarding third party attachments and additional advice for lots within a subdivision which may be further subdivided. Once these changes are finalised, they will be implemented into the general information section of all DIPs.

Padmount substation sites are a critical component of URD projects and site selection is a very important component of producing a compliant design. Padmount sites which will be impacted by civil works requirements need to be identified in the early stages of a project to ensure this does impact the delivery of the construction phase.

Retaining walls which are required to support a cut or fill situation for a padmount substation need to be designed and certified by a civil engineer and this certification needs to be presented and endorsed by Essential Energy prior to the design submission. Retaining walls should not be constructed within the boundaries of the padmount substation easement.

There have been a number of recent projects where retaining walls where required at the substation site and the required information has only presented after the original design submission. Identification of retaining walls on a construction plan needs to be detailed where they will have a direct impact on the electricity assets.

Recent projects examples have highlighted the importance of the identification of existing vegetation on construction plans. Construction of padmount substation sites under trees or deviating from the correct cable alignment are the direct result of construction plans not reflecting the current site conditions.

It is the Level 3 ASPs responsibility to ensure that the construction plan depicts the actual site conditions and what will also be constructed. Not identifying vegetation on plans which incur construction defects will require input from the Level 3 ASP which can have significant cost impacts to the project.

Vegetation removal requires the development of a vegetation management plan in many cases and this should be presented along with the Environmental Impact Assessment (EIA) and part of the design submission.

The accuracy and completeness of the Design Information Application (CEOF6010) Is important in ensuring that the Design Information Package can be developed and issued as efficiently as possible. In order to further streamline and eliminate delays the admin team have been filtering applications to ensure they are submitted fully completed and with the necessary attachments. The requirements were communicated across the latest ASP forums and the presentation from those forums can be accessed via this link: engage.essentialenergy.com.au/ASP.

The accuracy and completeness of DIA submissions will be very important as we continue to improve processing efficiency and remove delays.

When preparing conceptual designs for subdivisions which contain large corner lots, there should be consideration given to the potential to further subdivide. If the intent to further subdivide larger lots is known at the development stage of the electricity requirements, it is acceptable to produce a design which allows for the infrastructure to be installed at either corner of the lots to facilitate a two-lot subdivision.

To ensure new lots will be suitably serviced and future requirements met, as a minimum a single service point will be installed on larger corner lots with a provisional conduit installed to allow an additional connection point to be installed on the other lot boundary without the requirements for further trenching and excavation works.

Notification to existing lot owners is extremely important to avoid unwanted delays to a project when it enters construction phase. This is a reminder that part of the process to notify land owners requires a site meeting, to provide effected people an opportunity to be consulted and subsequent to this an enhancement letter would generally be sent out. Enhancement letters should not refer to completion of the project on behalf of or for Essential Energy as a contractor. Letters should identify the scope of the works and the responsible Level 3 ASP with the addition of the Level 1 ASP details if available.

What is Happening?

The Australian CIGRE Panel APB1, which deals with underground cables, has identified a general, industry-wide lack of underground cable systems experience and knowledge.

To address this, the Panel is planning to organise a three-day information and education seminar in Sydney later this year.

Discussions and presentations will cover all aspects of design, installation, maintenance, etc. of underground cable systems. At least one international expert will be attending as a guest speaker, and the seminar will also provide great networking opportunities.

A daily fee will apply. The amount is yet to be decided, but the panel is proposing to keep this to a minimum to encourage participation.

The Panel is keen to gauge the level of interest ASP Level 1s and Level 3s have in attending this type of seminar. Also, since seminar details are still being decided, your feedback is welcome and can be emailed to Panel member Graeme Barnewell. For example, would you prefer two days, rather than three?

Would you like to nominate specific topics to be covered?
