A recent case¹ has confirmed that a professional appointment for construction will usually be a “construction contract” under the Construction Act².

The appointment in question was to provide design and engineering works for a rail link between Manchester and Leeds. A dispute arose over payment, which went to adjudication. The employer argued that the adjudicator had no jurisdiction to decide the case because their appointment was not a “construction contract”.

The test of whether an appointment is a “construction contract” is whether it relates to “construction operations”. The Court found that preparing designs for potential construction works was a “construction operation”, and, therefore, the designer could refer the dispute to an adjudicator.

When appointing construction professionals, clients should ensure that their appointments:

  • include Construction Act-compliant payment provisions; and
  • specify adjudication rules, such as the Technology and Construction Solicitors Association (TeCSA) Adjudication Rules.

Standard form professional appointments already cover this.
