Set to launch in Spring 2026, the Public Buildings Construction and Infrastructure framework (PB4) will run until Spring 2030.

Firms are being urged to tender for projects that will see them help deliver, refurbish and manage essential public buildings, serving organisations such as the local authorities, education providers, blue light services and other critical services.

PB4 will be divided across ten distinct lots, tailored to cover a broad range of project types and values.

These include new build and refurbishment works, civil infrastructure, and hard facilities management, each designed to offer flexibility for public sector partners.

Appointments will be made across five key workstreams, with a focus on promoting high-quality service delivery, environmental sustainability, end-to-end project solutions with spaces reserved for regional and SME suppliers.

“This is a significant opportunity for businesses to play a direct role in shaping the future of Scotland’s public infrastructure,” said Lesley Peaty, regional director at SPA.

“The scale of PB4 means appointed contractors will help deliver essential buildings that communities rely on every day, from emergency services facilities to local authority hubs.

“As the largest framework we’ve ever launched, we wanted to ensure that PB4 offered far more than just pure economic potential.”
