AstraZeneca High Bay Warehouse | Slab Works
The Challenge
ACS was appointed to support critical slab works for a new high bay warehouse at AstraZeneca’s Macclesfield site — a highly sensitive and operational area.
Working closely with BES and HBL Associates, our role focused on ensuring that construction activity, particularly noise and vibration, would not disrupt pharmaceutical production.
Our Solution.
ACS Construction Group completed a range of complex refurbishment and construction works, including:
Slab Demolition
To start, the existing concrete slab had to be safely isolated from live buildings.
Once removed, the demolished material was crushed and recycled on-site, then reused as a pile mat — reducing waste and improving efficiency.
We poured a 1,800m² concrete slab at 450mm depth, using over 800m³ of concrete across four pours.
A laser screed was used to meet FM2 surface tolerance standards.
Key Elements
- 950 concrete piles broken and trimmed
- Reduce dig excavation
- 115 tonnes of rebar installed with waterproof membrane
- 670 anchor bolts precisely set out for future racking
Coordination
Our engineering team ensured accurate coordination to avoid clashes between bolts and rebar, maintaining quality and structural integrity throughout.
Outcome.
All works — including drainage — were completed on time and within a tight programme, with zero disruption to AstraZeneca’s ongoing operations.
This project demonstrates ACS’s ability to deliver complex structural packages in high-security, live environments with
precision and minimal impact.
