Collaborative Delivery for Complex Construction and Infrastructure Projects
In NEC programmes, collaboration determines performance.
Milestone strengthens collaborative delivery in complex construction and infrastructure environments. We combine behavioural leadership expertise with programme discipline to help Tier 1 contractors and client teams align and stay aligned across organisational and contractual boundaries — especially under pressure.
In live NEC and regulated projects, collaboration influences how well programmes are structured, how quickly decisions are made and how commercial tensions are handled. Milestone aligns leadership and planning, so teams build the clarity and collaborative maturity needed to keep delivery on track. We deliberately brought planning and leadership expertise together because most delivery challenges sit at the interface between people and programme — where contractual intent, behavioural dynamics and commercial reality meet.
Our work is structured around three integrated disciplines. Planning creates clarity. Leadership creates alignment. Collaboration builds the behavioural maturity that keeps delivery on track. Clients engage us for planning, leadership or collaborative delivery — and benefit from our understanding of how each affects delivery outcomes.

Collaborative Delivery
For over ten years, we have supported Tier 1 construction and infrastructure programmes, including defence and public-sector frameworks, at critical moments from procurement and mobilisation through delivery and recovery. We bring structure, clarity and practical discipline — helping teams deliver together when it matters most.
Programme clarity. Collaborative teams. Consistent leadership.
Milestone is led by Mick Underhill and Sally Calverley, who are supported by a team of programme and behavioural specialists working across complex construction and infrastructure programmes.
We are comfortable in difficult rooms. We understand commercial tension, live delivery pressure and the reality of challenging conversations — not in theory, but through years of involvement in major programmes at critical moments. We work calmly and strategically, helping teams surface issues early, think clearly and move forward with discipline.
Our perspective is shaped by the deliberate combination of engineering-led programme experience and behavioural leadership expertise. That combination allows us to see both the structural and human dynamics of a project — and to address them together.
In real programmes, planning, leadership and behaviour are almost inseparable. They are discussed daily in meetings, programme reviews and commercial decisions. Plans only work when people trust them. Leadership only holds when behaviour remains consistent. Collaboration only lasts when it is built into everyday ways of working.
We continuously develop our team so that Milestone standards — practical programmes, disciplined leadership and effective collaboration — are applied consistently across every engagement.
