The Data Capture Challenge - Innovative Solutions


Case Study - The Client’s Perspective
Powernet Ltd is a joint venture company which has been formed to manage, but not to own, the electricity networks in the province of Southland. The province spans 28,000 square kilometres (10,800 square miles) over the lower end of the South Island of New Zealand. The merger was in response to the reform and deregulation of the electricity distribution industry in New Zealand and is only one part of a total restructure of the incumbent electricity companies in Southland.

The shareholders and directors of Powernet recognised that the deregulation of the electricity industry would lead to a rationalisation of the number of power companies in New Zealand. This would seem inescapable when you consider that New Zealand has 44 power companies for 3 million people compared to England which has 12 power companies for 60 million people.

In order to manage the network efficiently, Powernet required accurate and comprehensive information on network plant and equipment, including an assessment of its present condition and an increased knowledge of the network customers’ requirements. This information had to be accessible to all parts of the organisation and be reliable to the extent that it could be used as the basis for better informed business decisions.

Powernet had inherited paper-based information systems that were deteriorating, time consuming to maintain and inaccurate. It became obvious that these systems required major rationalisation to allow the company to meet its fiture information needs. Powernet therefore decided to embark on a project that would provide a network information management solution through the employment of AM/FM/GIS technologies. The project was thus coined the Powernet Information Management Solution or PIMS. The primary objective of the project was: “to significantly enhance the content, accuracy and currency of network asset data, and provide universal access of this information to Powernet and its associated contractors”.

The key business drivers for the project were:
  • Ensuring comprehensive asset management
  • Meeting information disclosure regulations requirements
  • Allowing for calculation of optimised deprival valuation (ODV) of assets
  • Providing the required input data for Line Pricing Model and network analysis programmed
  • Providing the required input data for condition driven maintenance prograrnmes
  • Increasing efficiency in work practices through more accurate and timely information
  • Strengthening relationships with network customers through improved interface and understanding of their requirements
  • Establishing the key component to the total system integration process ie - “the backbone”.
In addition to meeting the above requirements the solution had to be innovative, flexible and built for the fiture in order to provide a sustainable, competitive advantage to Powernet. Establishing commitment from the management, directors and shareholders to the “vision” and fhture applications of PIMS was a key part of the business case.

Project Phase
The PIMS project commenced in February 1995 with an aggressive implementation programme consisting of 4 distinct phases over a 3 year period.

Phase one began with a pilot project which involved the capture of data from an area approximately 500 square kilometres (200 square miles) containing 7000 poles and 5500 customers. This was a critical phase in the project as it provided an opportunity to confirm the key benefits to the business and test processes prior to full implementation.

Phase two involves data capture of the entire network, consisting of approximately 100,000 poles and 8,500 distribution transformers. This phase encompasses an area approximately 20,000 square kilometres (8,000 square miles) and represents the largest geographical project of this type ever undertaken by a Power Company in New Zealand. Part of phase 2 is to extend the PIMS facilities out to a contracted network maintenance work force predominately for in-vehicle use. All 15 contracting companies will be users by the first quarter of 1997.

Phase three will involve the development and integration of fiu-ther sofltware applications to meet Powernet’s secondary functionality requirements. Phase four will ensure the extension of phase 3 functionality to all users across Southland.

The PIMS project team spent considerable time defining the data requirements necessary to meet Powernet’s diverse needs. The data required varied in nature from plant condition based data, connectivity data, pole attribution data, positional data and physical landbase features. Potentially as many as 80 variables can be gathered from any one pole site.

Having specified the data requirements it became apparent that the existing maps for above ground plant were not suitable. They lacked detail, were inaccurate and not current. Field inventory was therefore the data capture method of choice. The existing plans for the underground network, however, were very well detailed and met the required accuracy standard. Consequently these were digitised. Key Mimaganmt Processe s

Powernet recognised at the commencement of the project that the key critical success factor was not the hardware or the software solution that was chosen, but how the project was managed. For this reason Powernet was determined to manage this project efficiently over a relatively short implementation time frame and put in place the following processes and procedures to achieve this end:
  • Establishing a unique project team which brought together the best of breed for skills, expertise and experience
  • Partnering with all vendors rather than traditional vendor/client relationships
  • Selecting an expansive and representative Pilot Project
  • Including all key staff in the designing of requirements and specifications
  • Defining contract specifications and tendering procedures
  • Providing fair and reasonable commercial terms and conditions in all contracts
  • Utilising vendor assistance programmed which included a comprehensive Data Capture Guidebook, in-field training, joint development of data entry software, Powernet provided industry experts as required, and other forms of assistance
  • Defining criteria for acceptance of data and software deliverables
  • Communicating effectively with stakeholders throughout the project to maintain a high profile and commitment
  • Focusing on a Public Relations campaign with the general public and affected parties
  • Meeting regularly and reviewing the project with all project participants
Case Study - The Contractors Perspective
As previously stated, the prime motivator for the contractor is to ensure completion to the satisfaction of the client. Hence the client’s specific requirements and the data capture methodology that is able to meet those requirements are paramount to successful completion.

The PIMS Data Capture Services Contract was very specific and quantitative in the two important areas of scope and data acceptance criteria. These requirements provided the challenges specific for this project and in turn provided the catalyst for innovation. Specific challenges included aggressive timelines, some difficult and remote terrain and tight budgetary constraints. The areas of innovation that addressed these challenges were proprietary data capture software, the use in the field of physical digital landbases, portability of equipment and quality control methods that highlighted the effectiveness of digital imagery.
