Importance of Data Capture and Documentation During Rehabilitation Operations

Last modified by Administrator on 2016/05/06 16:10

Executive Summary

Due to the significant cost focus within the industry at the moment, in particular the scrutiny placed on the cost of rehabilitation operations, it is important to regularly track costs and productivity data to maintain the project budget and schedule.

Documentation of data (design vs as constructed surfaces, depth of topsoil application, progress photos etc.) is also important, particularly for mining contractors, to relinquish completed rehabilitation to the mine owner. The accurate capture and documentation of data through inspection and test plans (ITPs) ensures that rehabilitation technical specifications and reporting requirements are met.

Background

From my experience of rehabilitation works in the Bowen Basin, rehabilitation is rarely completed in a timely or cost efficient manner. Working for a contract miner, this is usually a result of:

  • having to share equipment between mining operations and rehabilitation works (blowing out the rehabilitation schedule); and
  • costs not being budgeted and tracked appropriately

Objectives

Improve the data capture and documentation of rehabilitation operations to make overall efficiencies in rehabilitation performance.

Methods

The project I was working on implemented the below methods to improve data capture, documentation and overall rehabilitation performance:

  • A contract surveyor was employed to get daily pickups to ensure compliance to design. The surveyor also assisted the mining superintendent to supervise operators and equipment movements
  • A schedule was developed and monitored daily (productivity vs machinery hours) to ensure the operations remained on track
  • Rehabilitation was treated as a part of daily operations and scheduling, progress and targets discussed in the daily production meeting
  • Separate cost codes were allocated for rehabilitation machinery so that utilization and costs could be tracked accurately
  • Rehabilitation areas were inspected with the Client regularly to ensure issues were resolved timely and efficiently
  • Design and design issues were discussed with operators on a daily basis

Results

The dedicated surveyor/civil supervisor contributed greatly to the success of the project. Mine surveyors generally don’t have the time to provide updates on a daily basis, which is what is required when the work is being scrutinized on a daily basis.

Outcomes

By implementing these improved methods for data capture and QA (best practice really), rehabilitation operations were completed on time and ahead of budget – a first for a rehabilitation project on this site.

By progressively recording and documenting QA data and keeping open and transparent communication with the Client, our ITPs were signed off and our area of responsibility relinquished without a hitch.
