Schools should start planning a SEND capital project as soon as an evidenced need and a credible funding route have been identified. They should not wait until the hoped-for opening date is only one term away.

Early planning does not mean committing to construction before funding or approval is secured. It means defining the requirement, assessing the site, identifying decision-makers and understanding the project’s critical risks. Planning permission, procurement, technical design, utilities and safeguarding can all affect the programme.

The safest approach is to work backwards from the intended occupation date and treat every approval as a project stage, not an administrative afterthought.

Key takeaways

• The construction period is only one part of a SEND building programme.
• Proportionate feasibility work can begin before final approval, subject to local requirements.
• Site constraints can affect the programme more than the building itself.
• Planning, procurement and technical approvals should be built into the timeline.
• Offsite construction can reduce activity on a live school site, but only when the project is properly coordinated.

Why does planning need to begin so early?

A funding allocation creates an opportunity to deliver a project. It does not produce a finished design, resolve site constraints or secure the approvals needed to build.

The RIBA Plan of Work divides a building project into eight stages, covering strategic definition, preparation, design, construction, handover and use. This is a useful reminder that the visible construction phase sits within a much longer decision-making process.

The Department for Education’s long-term estates planning guidance similarly advises schools and colleges to assess the condition, sufficiency and suitability of their estate before deciding whether to retain, adapt or replace a building.

For a SEND project, this early work must also determine what the space needs to enable. That may include specialist teaching, intervention, therapy, personal care, regulation, outdoor access or a combination of uses.

What are the main stages of a SEND capital project?

Every project is different, but most should progress through seven broad stages.

These stages are connected. A late change to capacity, access or safeguarding requirements can affect the design, cost and approvals already in progress.

Which stages are most likely to affect the deadline?

Site feasibility and surveys

A proposed location can look suitable while hiding issues below ground or within existing estate records.

Depending on the site, early investigations may need to consider:

• Topographical information and boundaries.
• Ground conditions.
• Existing drainage and utilities.
• Vehicle access and delivery restrictions.
• Levels and accessible routes.
• Trees, ecology or flood risk.
• Connections to existing buildings.
• Fire-service and emergency access.

The surveys required will depend on the site and professional advice. Their purpose is to identify constraints before they become changes during construction.

Planning

Where planning permission is required, the programme must allow time to prepare and validate the application as well as time for a decision.

The Planning Portal states that most applications are decided within eight weeks, with unusually large or complex applications generally subject to a 13-week period. These timescales begin once an application is valid and should not be treated as a guaranteed project programme.

Pre-application discussions, missing information, consultation responses, planning conditions or design amendments can add further time.

Procurement and internal approval

Schools, trusts and local authorities may have different procurement obligations and approval routes. A technically viable building cannot proceed until the organisation has the authority to appoint suppliers and commit expenditure.

The project plan should identify:

• Who owns the budget.
• Who approves the design.
• Which procurement procedure applies.
• Whether governors, trustees or the local authority must approve key decisions.
• Who can authorise changes.
• What evidence must be retained.

Schools should obtain appropriate procurement and financial guidance for their circumstances.

Building regulations and technical coordination

Planning permission and building regulations address different matters. Technical approval may require structural calculations, fire-safety information, energy assessments, accessibility details and coordination of building services.

ECAN’s guide to building regulations and fire safety for modular classrooms provides an overview of the information that may need to be coordinated before and during construction.

Technical decisions should be resolved before manufacturing begins. An unresolved doorway, service route or internal layout is more difficult to change after components have been produced.

Safeguarding and construction safety

A live school site cannot be managed like an empty development site.

The programme may need to address separated access, deliveries, working hours, noise, pupil movement, emergency arrangements and communication with staff and families.

Under the Construction (Design and Management) Regulations 2015, clients, designers and contractors have defined responsibilities. The Health and Safety Executive’s construction-planning guidance explains that the client must make suitable arrangements for managing the project and that a construction-phase plan must be prepared before construction begins.

Safeguarding should therefore shape the sequencing from the beginning, not be added after a contractor arrives.

What can a school do before funding is fully confirmed?

Subject to its local authority, trust and procurement rules, a school may be able to complete proportionate “low-regret” preparation without prematurely committing to construction.

Useful early actions include:

• Appointing a clear internal project lead.
• Agreeing the intended users and capacity.
• Gathering existing site drawings and utility information.
• Identifying possible locations.
• Recording operational and safeguarding constraints.
• Establishing the required opening date.
• Mapping the necessary approvals.
• Seeking an initial professional view on feasibility.
• Separating essential requirements from desirable additions.

Schools should confirm whether any early professional costs are authorised and eligible before incurring them. Funding conditions and procurement requirements vary.

How should schools work backwards from an opening date?

Begin with the date the building must be safe, commissioned and operational, not simply the date physical construction should finish.

Allow time before occupation for:

• Final inspections and certification.
• Testing building systems.
• Snagging and remedial work.
• Furniture and specialist equipment.
• Staff familiarisation.
• Updated fire, evacuation and safeguarding arrangements.
• Cleaning, setup and transition planning.
• Communication with pupils and families.

The final weeks should provide controlled preparation time rather than becoming an extension of the building programme.

For a closer look at the stages ECAN uses, see its guide to how long a modular classroom takes to build. Its published ranges are indicative only; the actual programme depends on the building, specification, approvals and site.

What can constrained-site projects teach us?

The Tops Day Nursery Isle of Wight project involved an 87m² bespoke early-years building delivered in a location with additional logistical challenges.

Eco-Classrooms and Nurseries related project-planning article explains that island access, restricted delivery windows and the need to limit disruption required careful coordination. Offsite manufacturing, a planned installation period and sequencing around the nursery’s operation helped manage those constraints.

The project is not presented as a SEND capital-funded building. Its relevance is the planning lesson: a constrained location does not necessarily prevent a project, but constraints must be identified early enough to influence design and delivery.

Moving from allocation to action

Eco Classrooms & Nurseries manages projects from initial consultation and design through planning, building regulations, offsite construction, on-site assembly and aftercare. Buildings can be produced using Structural Insulated Panels, or SIPs, which combine a structural facing with an insulating core. The EcoClassrooms and Nurseries guide to SIPs construction explains the system and the questions clients should ask suppliers.

Offsite construction may allow parts of the building and site programme to run in parallel. It does not remove the need for realistic scoping, surveys or approvals.

If you are working towards a particular academic or funding timetable, contact Eco Classrooms & Nurseries with your site, intended capacity and required occupation date. The team can help you identify the stages that need to happen first.

Frequently asked questions

Should a school wait for confirmed funding before starting any planning?

Not necessarily. Proportionate scoping and feasibility work may be useful earlier, but the school should confirm its authority to spend and avoid irreversible commitments before approval.

How long does a SEND building project take?

There is no universal timeframe. The programme depends on the scale, specification, site, procurement route, planning requirements and technical approvals.

Can construction be completed during the school holidays?

Sometimes, but it should not be assumed. Surveys, groundwork, utilities, assembly and commissioning must all fit the available period.

What usually causes delays?

Common risks include incomplete briefs, unresolved site conditions, planning queries, procurement requirements, utility connections and late design changes.

Is handover the same as practical completion?

Not entirely. The building may be physically complete, but the school still needs the relevant documentation, testing, familiarisation, furniture and operational arrangements before occupation.
