They set an ambitious time frame for completing the work and still met that commitment, even though additional work was requested by the Church and carried out during the course of construction. They adopted a ‘no surprises’ approach, communicating clearly and always kept us up to date with time frames, progress on various work fronts, and variations associated with additional work.
