Under The Building Safety Act, Gateway 2 approval is a critical step in ensuring that projects meet stringent safety and compliance requirements before construction begins. One of the key factors in achieving a smooth Gateway 2 submission is early design engagement, particularly in substructure waterproofing and protection. By involving specialists at the earliest stages, developers, architects and engineers can avoid costly delays, reduce risk, and ensure full regulatory compliance.
The Benefits of Involving Substructure Specialists Early (RIBA Stages 2 and 3)
1. Enhanced Design Accuracy
Why it matters: Substructure specialists bring a deep understanding of below-ground structures, soil conditions, and water management.
Benefit: This expertise ensures that the waterproofing design is robust, code-compliant, and prevents costly modifications later.
2. Improved Risk Management
Why it matters: Unidentified risks, such as groundwater ingress, structural movement, or gas exposure, can jeopardize compliance.
Benefit: Early risk assessments help mitigate potential failures, safeguarding long-term performance.
3. Cost Efficiency
Why it matters: Value-engineered solutions in waterproofing and gas protection can optimize both material use and installation methods.
Benefit: A cost-effective, compliant design from the outset prevents budget overruns and expensive rework.
The Power of Early Coordination Among Stakeholders
A lack of alignment between designers, contractors and suppliers can cause significant project delays and compliance challenges. Here's why early coordination is essential:
1. Streamlined Communication
Why it matters: Early collaboration ensures that all stakeholders - architects engineers and contractors - are aligned with the project goals.
Benefit: Prevents miscommunication and rework, leading to a smoother approval process.
2. Reduced Delays in the Gateway 2 Process
Why it matters: Misaligned expectations and late-stage design changes can create compliance bottlenecks.
Benefit: Proactive issue resolution keeps projects on schedule and avoids last-minute design conflicts.
3. Enhanced Quality Control
Why it matters: Ensuring quality standards from the start prevents non-compliance issues from surfacing later
Benefit: Results in a durable, long-lasting structure with reduced risk of failures
