Pacific Highway Upgrade - Woolgoolga to Glenugie

Location: 
North Coast, NSW
Total Project Value: 
>$500M

This project comprised an upgrade of approximately 26.3km of existing single carriageway to dual carriageways between Woolgoolga and Glenugie.  It included numerous standard form bridges, soft soil treatments and contaminated ground treatments. It also included a design and construct component for a heavy vehicle inspection station.

MIEngineers was contracted to prepare independent peer reviews of cost estimates for the proposed upgrade.

The review process employed for this project, as used for the majority of our estimate peer review projects, includes:

  • independently developing our own quantities
  • reviewing the quantity build-ups (involving random quantity checks against the drawings and takeoffs) and independently developing or suggesting our own rates
  • reporting and identifying whether the estimate quantity and/or rates are “Suitable” (i.e. the estimate quantity/rate is within ±10% of the independently developed quantity/rate), or high if above this range, or low if below this range.

In addition to the estimating work, MIEngineers was engaged to prepare technically correct and fit for purpose Quality Assurance construction and tender documentation, which involved the following process:

  • review of 15% detailed design drawings in order to identify any conflicts or potential contractual issues, so the design can be rectified
  • preparation of contract documentation at 85% detailed design stage for construction, ensuring the use of the latest model specifications; 
  • liaising with design team members and RMS as required; 
  • modifications to the model specifications including annexures, as required, to ensure the documentation accurately reflects specific requirements of the project;
  • if model specifications do not exist, sourcing and/or developing suitable non-model specifications; 
  • ensuring that the Schedule of Rates/Prices are consistent with Pay Items in the Specifications and, if Pay Items do not exist, developing new Pay Items;
  • amending documentation following reviews by RMS Infrastructure Contracts Branch and Independent Reviewer if/as required; 
  • update of contract documentation at 100% detailed design stage including redoing the above as required; and
  • amending 100% detailed design tender documentation following client review as required.

The key objective of the preparation of any tender document is to convey, without ambiguity, the required scope of works, the allocation of risks and responsibilities, and the commercial and legal conditions associated with the proposed contract. It is to create a 'no surprises' environment so that once the associated contract is on foot to the extent possible, there are minimal unforeseen issues that lead to additional claims. 

The RMS, in their review of some recent tender documentation prepared by MIEngineers, scored the work “10 out of 10” reflecting the quality of the documents, the minimal tender concerns over the documents, the cooperative liaison and the completion of the work well within time and budget.
