Variations and Scope Change

Variations and scope change are commonplace on modern projects. Our experts have provided expert witness advice on the validity and quantum of project changes on projects ranging from highway schemes in Africa to mixed-use developments in Dubai.

Variations and Scope Change examples

  • Southern African Hydro Scheme

    Quantum support for eco-friendly Southern African hydro scheme.

    Instructed to provide quantum expert services for underground civils works associated with a US$3.5bn pumped-storage power station in an extremely sensitive ecosystem in Southern Africa. The 1,332MW hydroelectric scheme comprises upper and lower dams 4.6km apart, connected by underground waterways passing through a subterranean power house with 4 x 333MW generators. Key issues investigated included NEC principle dispute on valuation methodology, challenge to adjudicator’s decisions, and disputed variations.

  • On-shore Oil Tank Farm

    Investigation of delays on Southern European oil tank farm.

    Appointed to produce independent expert report on issues relating to the engineering, procurement and construction (EPC) of a 630,000m³ onshore oil tank farm in Southern Europe. Associated facilities included pump station, substation, control/administration buildings, and truck loading facilities, together with jetty extending 1.5 km offshore, including topside facilities, mooring and loading platforms, marine loading arms, and associated pipework and civil works. Expert report considered variations, extension of time, design changes and delays to the EPC works.

  • Urban Regeneration Project

    Critical delay analysis of major city regeneration scheme.

    Performed expert delay analysis of critical path activities at one of Europe’s largest mixed-use urban regeneration projects in London, England. The transformation scheme, involving refurbishment and new construction, created a new cultural, retail and residential district in the capital. Delay issues included scope changes, permit and licence requirements, structural steelwork, and late party wall agreement. Expert report compared progress achieved in each of five buildings, as well as analysis of remaining duration and projection to establish project critical path.

  • Modularised Hotel

    Delay analysis helps resolve disruption issues on iconic modularised hotel.

    Appointed to perform expert quantum and delay services relating to the US$30m construction of a modularised hotel at a seaside resort on the south coast of England. The seven-storey building, comprising 215 hotel rooms and 29 apartments, used a lightweight modular construction system to save on costs and materials. Reviewed issues relating to scope changes, prepared daily design, manufacture and installation ‘as-built’ programme, and produced and analysed detailed progress curves for an adjudication hearing.
