The pad layer of London’s vertiport network.

vertipad.london specifies, engineers, and commissions modular landing pads on Class-A rooftops, podium decks, and greenfield estates across Greater London. One published spec, one diligence pack, one operator interface — sized to make air-mobility infrastructure legible to landlords and their underwriters.

Feature — 02 / Pad Overview

The Brief

A standardised pad kit for institutional-grade rooftops.

The pad layer is where airspace access meets the building envelope. Every vertipad is delivered under a single reference specification so that landlords, engineers, and insurers can benchmark installations across a portfolio — not negotiate each rooftop from first principles.

Feature

Standardised specification

Every pad ships against a published spec — TLOF/FATO geometry, load class, drainage, lighting, and firewater. Landlords get comparable diligence across the entire portfolio.

Feature

Retrofit-first engineering

Structural playbooks for post-tension concrete, steel-frame, and podium decks. Survey-to-commissioning target of 14 weeks with named engineer of record.

Feature

Insurance-ready dossier

Each installation is issued with a structural load certificate, acoustic envelope report, and CAA operational envelope — pre-formatted for underwriter review.

Feature

Charge-ready by default

Every Type P2 and P3 pad is delivered with reserved electrical capacity and conduit runs for on-pad DC charging, sized to current OEM airframe roadmaps.

Feature

Modular hardware kit

Support truss, safety net, perimeter lighting, and marking are supplied as a coordinated kit. Component swaps within a 24-hour operational window.

Feature

Portfolio interoperability

Shared operating model with vertihub.london at the terminal layer and evtol.london at the network layer. One diligence pack; one operator interface.

Feature — 03 / Pad Typologies

Reference Grades

Three pad grades mapped to London’s rooftop and podium stock.

Grade	Footprint	Structural Load
Type P1 Single-Pad Rooftop Retrofit The core Class-A rooftop retrofit: single TLOF circle, integrated safety net, and modular support truss. Optimised for existing commercial towers with unused mechanical deck area.	9,000–14,000 sq ft	220 psf min.
Type P2 Twin-Pad Rooftop Cluster Two operational pads with a shared FATO and passenger lounge. Suited to trophy assets with peak-hour throughput ambitions and dedicated tenant sky-lobby integration.	16,000–28,000 sq ft	290 psf min.
Type P3 Podium & Greenfield Pad Ground-up podium pads on mixed-use developments and greenfield estates. Site-cast structural slab, integrated firewater, and full landside marshalling apron.	12,000–22,000 sq ft	Site-cast

Feature — 04 / Retrofit Playbook

Survey → Commissioning

A 14-week retrofit playbook, published end-to-end.

01

Desk Screen

Structural, zoning, and acoustic pre-screen from public data and portfolio disclosures. Delivered as a two-page qualifying memo within five working days.

02

Structural Survey

On-site engineering survey, non-destructive testing, and load-path modelling. Independent engineer of record signs the certificate that anchors underwriting.

03

Kit Specification

Pad typology selected from the reference grades (P1 / P2 / P3). Kit is coordinated with landlord MEP, façade, and life-safety consultants.

04

Commission & Handover

Install, commissioning tests, acoustic envelope confirmation, and CAA operational envelope handover. Building operations team is trained on-site.

Feature — 05 / Engagement

Engage the vertipad.london engineering desk.

The desk works with a bounded set of landlords, developers, and consulting engineers. Structural screens are scheduled within ten working days; portfolio roll-outs are scoped under a framework agreement.
