Neumann Contractors v Wyong Shire Council [2010] NSWSC 614

The contract did not permit Neumann to excavate below the top of waste profile where the exposed material met cover soil requirements, nor to excavate more than 100mm below that profile for cover soil purposes, and Superintendent approval was required but not given. Neumann's over-excavation and exposure of waste destabilised the southern landfill and adversely affected impact rolling, so sandstone used as a bridging layer and the impact rolling trial were not compensable variations.

Building and Engineering Contracts Dispute Concerning Council's Cross Claim to Recover Alleged Overpayment After Adjudication Determinations Under the Building and Construction Industry Security of Payment Act 1999 (nsw) / Principal Judgment on Remaining Cross Claim; Final Orders and Costs Stood Over

Legal Issues

  1. 1 ['Whether the contract required or permitted Neumann to excavate existing fill beyond the top of waste profile if the material then at the top of waste profile met the specification requirements for cover soil' 'Whether the contract required or permitted excavation more than 100mm below the top of waste profile if additional excavation was necessary to ensure the cover soil layer met the specification requirements' 'Whether excavation beyond the top of waste profile required approval of the Superintendent' 'Whether the Superintendent gave approval to excavation beyond the top of waste profile' "Whether the excavation performed adversely affected the site's ability to be impact rolled" 'Whether the Specification provided that impact rolling was to be conducted on a 100mm layer of cover soil' 'Whether the thickness of the cover soil layer as a working surface was temporary works necessary for the contractor as part of the lump sum for impact rolling' 'Whether the impact rolling trial was a variation to the contract' 'If importing and laying crushed sandstone was compensable under the contract, what rate was payable' 'Whether the contract awarded on 20 December 2006 included a fixed price for piling of the underground tanks' 'If not, what amount was agreed to be paid for piling of the underground tanks']
