Most delay and planning instructions don’t need a 200-person consultancy. Some do. The choice gets easier if you start from the problem rather than the brand.
When a large firm is the right call
- The dispute needs delay, quantum, engineering and forensic accounting experts under one roof, on one timetable.
- A framework or panel names the supplier, or the Client’s procurement rules set a PI insurance level a small firm can’t carry.
- The job needs a standing controls team of 10 or more on site for years.
When a boutique fits better
- The question is time: a rejected programme, a stalled compensation event, an EoT refused, an adjudication notice on the desk.
- Continuity matters. The person who built the programme record should be the person who explains it.
- Pace matters. Under NEC4 the Project Manager has 2 weeks to accept a programme (31.3) and 1 week to reply to a compensation event notification (61.4). Your adviser has to move at that speed.
- Conflicts. A firm with dozens of live framework relationships can be conflicted out of the matter you need help with.
5 questions to ask either
- Who will do the analysis, and who signs it?
- Has their delay analysis been tested in adjudication, and what was the result?
- Which SCL Protocol method do they propose, and why does it suit your records?
- If they are acting as independent expert, have they prepared or advised on the claim? They shouldn’t have (CPR Part 35 where it applies).
- What PI cover do they hold?
VERTX is a boutique by design. The director scopes the work, does the analysis and signs the report. If your matter needs a multi-discipline team, we’ll say so on the first call.
