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

  • Underground Civils Works

    Construction of the main underground civils works to a pumped-storage power station, including intake pipework, power house complexes and mains access tunnels. Key issues included: NEC principle dispute on valuation methodology; challenge to adjudicator’s decisions; and disputed variations.

The works were also to include necessary soil investigations, pile testing, dredging and partial reclamation of the shore to accommodate jetty support facilities.

    Blackrock Expert Services was instructed to produce an independent expert report on the issues of: variations; extension of time; design changes; and delay.

  • Urban Regeneration Project

    Mixed-use urban regeneration project consisting of 5 buildings, with total site area of 5.8 acres, comprising commercial, residential and retail space. Key issues included: change of scope; permit and licence requirements; steelwork issues; and late party wall agreement.

    Blackrock Expert Services provided a detailed comparison between the status and progress achieved in each building at periodic points of time, as well as analysing the remaining duration and projection to establish the actual critical path of the project. A report was then produced, determining the critical activities that led to the project delay.

  • Modularised Hotel

    A modularised hotel comprising 215 hotel rooms and 29 apartments. Key issues included: change of scope; shell and prefabricated modules; additional scope; and disruption.

    Blackrock Expert Services prepared a daily design, manufacture and installation as-built programme, and detailed progress curves were produced and analysed for an Adjudication hearing.
