CPD

CPD for architects and engineers.

In-house sessions on BS 8102:2022, podium decks, and Building Safety Act compliance. Led by Ben Hickman, contributing member of the BS 8102:2022 committee.

From BS 8102:2022 committee contributors

Continuing Professional Development for design-decision-grade audiences.

CLW delivers in-house CPD sessions on structural waterproofing design, BS 8102:2022, podium decks, ground gas mitigation and below-ground compliance under the Building Safety Act. To architectural practices, structural engineering consultancies, project management firms, and Tier 1 contractor design teams across the UK.

Sessions are designed for the technical seniority of the room: not consumer-grade introductions, but the design-decision-grade content that practising architects, engineers and project managers ask about when they encounter a below-ground waterproofing question on a live project.

CLW's sessions are led by Ben Hickman, Past Chair of the Property Care Association, contributing member of the BS 8102:2022 committee, and Technical Director of CLW.

Why book CLW

Why architects and engineers book CLW for CPD.

Below-ground waterproofing is the technical area architects and structural engineers most consistently describe as outside their core competence. And the area where downstream failures most consistently consume programme, cost and client trust. CLW's CPD addresses that gap directly:

  • Authority. Each session is delivered by a designer who sat on the BS 8102:2022 standard-writing committee and who chaired the Property Care Association.
  • Currency. The content reflects what the standard now requires, not what waterproofing practice looked like a decade ago.
  • Practical bias. The material is built around design decisions and failure modes from CLW's live commercial project portfolio.
  • Coordination focus. Sessions address the interface between waterproofing, structural design, M&E and architectural finishes.
  • Independence. CLW does not sell waterproofing products. The CPD is product-neutral.

Sessions available

Four 45-minute sessions to choose from.

Session 01 · 45 minutes including Q&A

BS 8102:2022, Performance Grades and Design Responsibilities

Covers: BS 8102:2022 Table 2 and the four performance grades; where Grade 1B and Grade 2 are most often confused; combined-protection requirements at Grade 3; the competent waterproofing designer expectation under Clause 5; the documentation chain (Design Philosophy → Risk Assessment → Performance Specification → Monitoring); 2009 vs 2022 differences; Building Safety Act interface.

Session 02 · 45 minutes including Q&A

Podium Deck Waterproofing, Design, Selection and Failure Modes

Covers the four common podium deck waterproofing strategies and where each fits; interface design at parapets, planters, drainage outlets, columns and movement joints; buried roof vs inverted roof vs blue/green roof; the most common failure patterns from CLW's expert witness portfolio.

Session 03 · 45 minutes including Q&A

Ground Gas in Basements, BS 8485 and BS 8102 in Practice

Covers ground gas characteristic situations under BS 8485 and what each requires; where waterproofing and gas-resistant membranes intersect; methane, CO₂, radon and VOCs; combined-protection strategies for gas and water.

Session 04 · 45 minutes including Q&A

Below-Ground Waterproofing under the Building Safety Act

Covers how Building Safety Act dutyholder obligations interact with BS 8102:2022 documentation expectations; competence and design responsibility evidence requirements for Higher-Risk Buildings; practical Stage 2, Stage 3 and Stage 4 dutyholder evidence.

How it works

A four-step session.

  1. You request a session using the form below, telling us the practice, the location, the audience (rough numbers and seniority), and which of the four sessions interests you.
  2. We confirm a date within typically 2–4 weeks of request.
  3. We deliver the session at your studio (or remotely).
  4. Attendees receive a CPD attendance record and the supporting reference material.

There is no charge for the CPD session itself. CLW invests in CPD as part of its market presence; we don't bill for it.

What CLW does NOT do

The honest disclosures.

To anticipate the question every architect and engineer asks:

  • We do not sell waterproofing products. We are not a manufacturer or a contractor.
  • We do not pitch CLW's services from the front of the room. The session is the technical content.
  • We do not promise a follow-up engagement. The CPD is delivered as CPD.

If, after the session, your practice has a live below-ground project we can help with, the route to engagement is the same as for any client. A direct conversation at the right RIBA stage.
