Lump Sum Construction Only

  • Under this method a principal will engage consultants to produce complete design documents

  • The principal will call tenders from potential builders

  • A contractor will be engaged to undertake the agreed scope of works for an agreed lump sum price

  • The contractor will not be responsible for any design work and changes to the scope or design will be treated as variations

  • This method is most effective when the principal’s design is complete, allowing contractors to offer a lump sum

  • Principal retains control of the design consultants

  • Ensures the principal gets competitive market pricing combined with certainty around the final project cost at an early stage
