Estimating & Pre-Construction

At Advanced Glass Glazing and Façade Services, we know that the success of any façade package starts long before installation. Our Estimating and Pre-Construction teams work closely with main contractors, architects, and consultants to ensure risks are identified early, costs are realistic, and compliance is fully built into the design.

By engaging us at pre-construction stage, contractors gain the benefit of technical expertise and accurate cost planning, reducing the risk of redesigns, delays, and non-compliance later in the programme.

How We Add Value at Pre-Construction Stage

Early Design Support

We review specifications, drawings, and performance requirements to advise on the most suitable systems, including curtain walling, aluminium windows and doors, rainscreen cladding, and complementary systems such as fire stopping, louvres, and door automation.

Accurate Estimating

Our team provides detailed quotations that take into account system performance, regulatory compliance, and buildability, giving contractors cost certainty from the outset.

Regulatory Compliance Advice

We ensure façade designs align with Approved Documents B, L, M, and Q, as well as CWCT testing requirements and the Building Safety Act Gateway process.

Value Engineering

Where budget or programme pressures exist, we propose compliant alternatives using trusted systems from Technal, Senior Architectural Systems, and Aluprof, ensuring performance is never compromised.

Programme Alignment

We work with contractors to phase procurement, fabrication, and installation in line with project milestones, reducing risk of delay.

Risk Reduction

Potential issues — such as tolerance conflicts, fire stopping detailing, or integration with SFS — are identified early, ensuring smoother delivery on site.

Why Contractors Trust Advanced Glass

By combining technical knowledge with commercial awareness, our Estimating & Pre-Construction service helps contractors secure projects with confidence.
