Mid-sized contractors — those running roughly 3 to 15 concurrent live projects — face a distinctive commercial economics problem. Their portfolios are large enough that senior commercial oversight matters. They are not large enough that hiring senior commercial capacity into every project team is affordable. The result is a chronic mismatch between the senior commercial oversight the portfolio needs and the senior commercial oversight the contractor can afford to staff.
This article sets out the underlying economics — why the problem exists, why per-project hires don't solve it, and why the shared-capability model produces materially better economics for mid-sized contractors. It is neither theoretical nor a sales argument; it is the observation from working across dozens of mid-sized contractor engagements over recent years.
The base problem: senior commercial capacity is a fixed cost
A senior commercial director capable of running contract management, claims positioning and commercial governance across multiple projects costs roughly the same whether they cover one project or ten. Their compensation is dominated by their experience and market rate, not by the workload they carry.
This creates a structural economics problem for mid-sized contractors. On a single-project basis, the senior commercial director is disproportionately expensive against the project's margin envelope. Spread across multiple projects, the senior commercial director's cost becomes affordable — but their capacity to actually provide senior oversight to every project degrades as project count rises.
The typical mid-sized contractor solves this with a single senior commercial director covering 5-10 live projects. The economics work on the cost side. The oversight degrades on the capacity side. Every commercial director we've worked with running this model has, when candid, described their week as 'firefighting whichever project is most on fire.' None of them describe it as running senior oversight across every project consistently.
Why staffing per project doesn't fix it
The obvious solution — put a senior commercial manager into every project team — doesn't work economically. Even at mid-market compensation rates, adding a senior commercial manager to every live project across a portfolio of 5-10 projects typically adds 2-4% to the contractor's overhead cost base. For a mid-sized contractor running 3-6% margins, this is not affordable.
The other obvious solution — hire more mid-level commercial managers rather than senior ones — solves the capacity problem but doesn't solve the oversight problem. Mid-level commercial managers execute; they don't govern. What the portfolio needs at senior level is standards-setting, exception review, escalation handling, portfolio visibility. These are not tasks that scale by adding execution capacity.
The result is that mid-sized contractors either accept degraded senior oversight, accept unaffordable overhead, or find a third structural solution. The third solution is shared senior capability.
How shared senior capability changes the economics
Shared senior capability separates the senior oversight function from the execution function. Senior oversight is provided by a pooled senior team — one senior contract lead, one senior commercial lead, one senior claims lead — working across the contractor's live projects at defined cadence, applying consistent standards, reviewing outputs, handling escalations.
Execution is delivered by a supporting delivery team running standardized workstreams (notice tracking, variation registers, CVR, commercial reporting) to defined SOPs. The delivery team scales with the contractor's project volume; the senior oversight scales more slowly because senior oversight is fundamentally a governance and review function, not an execution function.
The economics of this model are structurally better than per-project staffing for two reasons. First, senior oversight is pooled across the portfolio rather than duplicated per project — spreading a senior cost that was going to be spread anyway, but doing it with defined coverage rather than 'firefighting whichever project is most on fire.' Second, standardization of execution workstreams produces efficiency gains that per-project execution cannot match — templates get reused, protocols get refined, learning accumulates.
The break-even point
Shared senior capability doesn't produce equal value at all portfolio sizes. There is a break-even point below which the shared model doesn't outperform in-house per-project staffing, and above which it does.
The typical break-even point sits around 3-4 concurrent live projects for a contractor with an existing internal commercial function. Below that, the contractor's internal commercial team can maintain adequate coverage. Above that, the shared model starts producing measurable value in oversight quality, standardization and cost efficiency.
The value increases with portfolio size. A contractor with 8-12 live projects typically sees the strongest return on shared capability — because portfolio-wide standardization, cross-project claim exposure visibility, and consolidated commercial reporting all deliver benefits that scale with project count.
The buyer usually discovers this through crisis
The typical path to adopting shared capability is not analytical — it is empirical. A contractor experiences a specific commercial event that reveals the oversight gap: a project that surprised at year-end, a claim that was under-prepared, a distressed job that had been drifting invisibly, an audit that flagged inconsistent discipline.
The response is usually to engage external senior support on the specific event. What contractors then discover is that the specific event was not the underlying problem — it was a symptom of the oversight gap that pooled senior capability solves. Engagements that start as event-specific frequently extend to portfolio retainers because the contractor recognises the structural problem is portfolio-wide.
This progression — event to retainer — is common enough that it should be treated as the default adoption path, not the exception. Contractors evaluating shared capability rarely commit to a full retainer as a first step. What works is engaging on a specific event, seeing the value, and extending progressively.
What this means for how Ashforte engages
Ashforte is structured around this economics. Our engagement models — Portfolio Retainer, Project-Embedded, Fixed-Fee Claim Package, Tender Sprint, Initial Commercial Risk Assessment — reflect the natural adoption progression from event-specific to portfolio-wide.
The Initial Commercial Risk Assessment is deliberately the entry point. It costs the contractor nothing and produces a documented, actionable view of one live project. It lets the contractor experience the shared-capability model on a specific project before committing to broader engagement. Most Snapshots either identify enough exposure to justify further engagement immediately or reassure the client that a specific project is in better shape than they feared. Either outcome is useful.
For mid-sized contractors reading this article — if the economics described here match your situation, the initial assessment is the fastest way to see the model applied to your own portfolio. It is a small commitment for a documented output. And it is designed to be the beginning of a longer conversation, not the beginning of a sales cycle.
