This article explores the details of the inspection service plan, outlining the specific stages of a building project that will require inspection.
We offer an insight into what to expect during inspections and how to prepare for each stage. This can apply to all stakeholders in the project, from construction workers to the project manager – everyone should be aware of their role in the building control inspection process.
Why building control inspections exist
Ensuring a building is safe, serves its purpose and is comfortable is the overall objective of a construction project. To verify the project meets these targets building control inspections have been established.
An inspection checks compliance with the building regulations and identifies potential issues that need to be addressed.
Building control inspections follow a structured approach, with specific stages being set out in the Inspection service plan.
Good to know – regional variations
It's important to note that specific inspection requirements may vary depending on your region. Always check with your local building authority or Approved Inspector (if appropriate) to make sure you are aware of the regulations.
1. Pre-construction inspection
This initial inspection takes place before the project commences. It will:
Ventilation ductwork plans will be assessed to ensure it is to be installed to maximise efficiency.
- Assess site conditions – this stage examines the foundations, drainage systems, and potential ground hazards to check the suitability for the planned construction.
- Review material specifications – to ensure the chosen materials meet the required standards for strength, durability, and fire resistance.
2. Inspections during construction
There are likely to be several inspections as the project develops, depending on factors such as project size, construction type, building age if a renovation and external conditions.
- Foundations - factors such as soil bearing capacity and reinforcement will be inspected as the foundations must be able to support the building's weight.
- Drainage - correct drainage prevents moisture issues and foundation damage. Problems with moisture can lead to damp and mould, which is why mechanical ventilation should be considered when planning the project.
- Underground utilities - confirms the location and installation of underground utilities like power lines and plumbing pipes.
Structural inspections
As the building takes shape, the building control inspection focuses on its structural integrity:
- Frame materials and techniques - to verify the quality and proper installation of the frame materials such as wood or steel.
- Load-bearing walls and floors - to ensure they can handle the intended loads.
- Fire safety – to check the installation of fire-resistant materials and fire escape routes to meet the building regulations.
Building envelope
This inspection focuses on the barrier between the interior and exterior of the building:
- Wall construction – to check insulation has been installed correctly and in compliance with energy efficiency standards.
- Roofing materials – to ensure the roof is structurally sound, waterproof, and has flashing correctly installed to prevent leaks.
- Windows and doors - to confirm correct installation, functionality, and compliance with energy efficiency and safety regulations.
Ventilation System
After installation, the inspection will check:
- Ductwork - to ensure ducts are properly sealed, free of leaks, and are supported correctly.
- Fresh air intake and exhaust locations - to confirm these are positioned correctly and are free of obstructions.
- System functionality – to ensure proper airflow and indoor air quality in compliance with Approved Document F of the Building Regulations.
Good to know – regulation-compliant ventilation
We can help you with ventilation system design and installation that complies with the necessary government regulations. Whether you're a self-builder or a construction development company, we can help you ensure your ventilation installation meets the inspection service plan requirements.
Internal systems
With the shell of the building complete, the inspections focus on the internal systems:
- Electrics – to verify the safety and operation of electrical wiring, sockets and control panels.
- Plumbing - to ensure proper water supply, drainage, and waste disposal systems are installed according to the relevant building codes.
3. Final inspection
The final part of the inspection service plan makes sure the completed building meets all the relevant building regulations and is ready for occupancy.
- Overall operation – the building inspector will check all systems function correctly, from plumbing and electrical to ventilation and fire safety.
- Ventilation - the airflow, filters and control system will be tested to ensure proper air distribution, accessibility to parts for future maintenance and efficient operation.
- Accessibility – to confirm the building adheres to accessibility regulations for people with disabilities.
Upon successful completion of all inspections, a certificate will be issued that confirms the building's compliance with the building regulations.
Good to know – Building inspector registration
From April 2024, UK building inspectors must be registered with the Building Safety Regulator. This is to ensure that inspections and competency levels are of the highest standard.
How to prepare for a building control inspection
To ensure a smooth and efficient inspection process:
- Schedule inspections well in advance to avoid delays and ensure inspectors are available.
- Have all relevant design plans, product specifications, and building codes readily available for the inspector to check.
- A clean and organised worksite allows for easier inspection and avoids potential safety hazards.
- Maintain clear communication with the inspector, addressing any questions or concerns promptly.
Following the guidelines above can help ensure your building project meets the necessary standards and follows a smooth inspection process.
3 points to remember
- Building inspections take place throughout the construction process
- Certification cannot be issued until building inspection approval is granted
Approved Document F refers to ventilation regulations
