Why Continuity Across Project Phases Matters More Than Most Providers Realise

Housing and care projects typically move through a predictable sequence of phases: feasibility, design development, procurement, construction, and handover. In most advisory models, a different team handles each one. The strategy consultant does the feasibility. A project manager is engaged for design. A superintendent arrives for construction. A defects manager closes out the DLP. Each transition is framed as a clean handoff from one expert to the next.

It sounds efficient. In practice, it's one of the most reliable ways to erode budget, programme, and build quality simultaneously.

What Actually Gets Transferred at a Handoff

At every phase transition, a new team inherits the project. What they receive is the documentation — the cost plan, the design drawings, the programme, the contract — and a brief handover conversation if they're fortunate. What they do not receive is the reasoning behind the decisions. The context that shaped them. The understanding of why the brief reads the way it does, what the client actually needs (as distinct from what was written down), what risks were identified and consciously accepted, and what trade-offs were made along the way.

This is the distinction between explicit and tacit knowledge. Explicit knowledge is what appears in documents. Tacit knowledge is what lives in the heads of people who were in the room when the decisions were made — the understanding of a project that can't be fully codified, only experienced. Construction project management research has consistently found that this kind of knowledge is the most valuable and the hardest to transfer. A handoff captures the former and loses almost all of the latter.

For housing and care providers, the consequences land on the project. The incoming team makes decisions based on incomplete understanding. They interpret documentation through the lens of their own assumptions rather than the context of the project. They re-examine questions that were already settled, consuming time and budget. They miss the significance of constraints that seem minor on paper but were actually central to how the project was structured.

Where the Losses Show Up

The effect of knowledge loss at phase transitions rarely announces itself as such. It shows up as variations. As disputes. As design decisions in construction that contradict the intent established at feasibility. As superintendent rulings that conflict with what the client understood the contract to require. As defects that weren't anticipated because the person managing the DLP wasn't across the construction programme.

Rework from unplanned changes is one of the most studied failure modes in construction project management. Research from the University of Salford, drawing on Construction Industry Institute data, has consistently found that rework costs can amount to 10 to 15 per cent of contract value. Much of this rework traces back not to poor construction but to poor information transfer — design intent lost in transition, decisions reversed by teams who didn't understand why they were made.

For aged care or community housing projects where margins are already tight, a 10 to 15 per cent rework exposure isn't an abstract risk. It's a project-threatening number. And it grows larger the more phase transitions the project passes through.

Design Drift: How Intent Gets Diluted

One of the most damaging specific forms of knowledge loss across project phases is what practitioners call design drift — the gradual dilution of design intent as interpretation passes from one team to the next.

A project brief is established at feasibility. It captures the client's operational requirements, the resident experience objectives, the regulatory compliance framework, and the cost constraints. The design team at schematic stage translates that brief into drawings. At design development, a different team refines those drawings. At tender, a contractor interprets them. On site, subcontractors make daily decisions about how to execute what the drawings show.

At every step, someone makes a judgement call about what the documentation means. Without access to the people who wrote it, those judgements are made on inference rather than knowledge. Each individual decision may be reasonable in isolation. Cumulatively, they can produce a building that is technically compliant with the drawings but materially different from what the client needed.

For aged care facilities, where design decisions directly affect resident safety, dignity, and operational efficiency — room layouts that support care delivery, circulation routes that work for mobility aids, spaces that are legible for residents with cognitive impairment — design drift has consequences that persist for the life of the building. For community housing, where every square metre of communal space and every storage cupboard has to work for the people living there, decisions made on inference rather than intent produce buildings that fall short of what was possible.

The Brief as a Living Document

Related to design drift is brief drift — the phenomenon where the project's stated objectives gradually shift as the team changes, and the original intent becomes harder to locate.

Client organisations aren't static across a project lifecycle. Personnel change. Boards turn over. Strategic priorities evolve. A project that takes three to four years from feasibility to handover will often see significant change in the client organisation along the way. Without an advisory team that has been present throughout and holds the thread of what was originally agreed, these organisational shifts can introduce scope changes, priority conflicts, and renegotiated expectations that extend programme and increase cost.

A team that has been on the project since feasibility can hold the organisation's own brief back to it when internal pressure to change course starts to build. A new team arriving at design or procurement has no anchor point. They manage what they're told, not what was intended.

Programme and Cost: The Compounding Effects

Beyond design quality, phase transition creates direct programme and cost risk through the time required for an incoming team to become functional on a project they didn't set up.

There is no such thing as an instant handoff for a complex housing or care project. An incoming superintendent who hasn't been across the design and procurement process needs time to read the contract, understand the scope, and develop working relationships with the contractor and subcontractors. An incoming defects manager who wasn't present for practical completion needs time to understand what was flagged and what was accepted. In a market where programme delay carries financial cost at every stage — financing charges accumulate, cost escalation continues, resident occupancy is pushed back — that ramp-up time is not neutral.

There is also the risk of duplicated effort. An incoming team often needs to re-examine decisions already made — re-engage consultants, re-review documentation, re-run assessments — because they can't distinguish between decisions that are settled and decisions that warrant revisiting. This duplication isn't incompetence; it's the rational response to incomplete information. But it costs time and money that a continuous team would not spend.

What Continuity Actually Looks Like

Delivering continuity across a project lifecycle isn't about having the same individual present at every meeting. It's about ensuring that the people with decision-making authority and client accountability stay with the project from feasibility through to handover — that the person who helped structure the brief is the same person reviewing design development against it, administering the contract against the scope they helped define, and managing the DLP against the quality standard they helped establish.

In practice, this means:

Senior practitioners stay on the project. Not overseeing from a distance while junior staff manage day-to-day. The senior person is across the project detail at every stage because they've been there from the start and because complex housing and care projects require that level of judgment throughout, not just at initiation.

The client relationship is continuous. The provider organisation has one point of contact who understands the project's history, the board's risk appetite, the funder's requirements, and the internal dynamics that affect how decisions get made. There's no re-establishing trust and context every time a new team arrives.

Decisions are traceable. When a variation is raised on site, the team administering the contract knows whether the variation represents a genuine scope gap or a contractor's attempt to recover margin on work that was always in scope — because they were present for the tender, the negotiations, and the scope clarification process.

Handover is genuinely prepared for. The DLP management process begins during construction, not after practical completion. The team knows what was flagged, what was accepted under agreed conditions, and what the contractor committed to rectify. The client isn't starting from scratch with a new team trying to piece together the construction record.

Why This Matters Particularly in Housing and Care

In commercial development, the cost of phase-transition knowledge loss is significant but often recoverable through contingency or programme extension. In housing and care delivery — where margins are constrained, funding envelopes are fixed, programme milestones are tied to grant conditions or regulatory requirements, and the end users are often vulnerable people who have been waiting a long time — there is much less capacity to absorb these losses.

Aged care providers, community housing organisations, SDA developers, and crisis accommodation operators are not development companies with deep reserves and diversified portfolios. They are mission-driven organisations managing complex projects on tight budgets with high accountability to residents, boards, and funders. The project team they engage carries a significant share of the institutional knowledge of the project. Losing that knowledge at each phase transition isn't a minor inefficiency. It's a structural risk to delivery.

MakeSpace is built around continuity. Senior practitioners stay on every project from feasibility through to the end of the defects liability period — no B-team, no graduate handoffs, no new team arriving at construction who didn't understand what the brief required. If you're planning a project and want to understand what that looks like in practice, we'd be glad to talk it through. Get in touch.

MakeSpace is a not-for-profit project advisory and client-side delivery consultancy, and a subsidiary of Unison Housing. Retained earnings are reinvested into the housing sector — so each project we help deliver helps fund the next.
