Promenade Towers
A riser evaluation survey, a two-stack pilot, then 70 vertical riser stacks lined across two 18-story towers.

Industries
Multifamily & condominiums, without a full re-pipe
Apartments, garden-style communities, and low, mid, and high-rise condominiums. Our highest-volume industry, with 127 of 286 cataloged buildings.
The challenge
In a multifamily building, one failing stack reaches every home above it, and every resident feels it.

Our experience
What we see in Multifamily & Condominiums
- 01
Apartments
Rental communities where every shutdown affects residents. We coordinate directly with property management to schedule the work and notify residents, keeping disruption to a minimum.
- 02
Garden-Style Communities
Multi-building communities with long runs between buildings. At Ascott Place in Tampa, the work covered 231 units across 59 buildings, completed in March 2022.
- 03
Low, Mid, and High-Rise
From low-rise condominiums to luxury high-rise towers, vertical stacks carry the most risk: a failure in a lower section backs up every floor above it.
- 04
Reserve Studies Built on Real Data
Condominium boards plan reserves years ahead. A condition-graded evaluation gives the reserve study real pipe data instead of age-based estimates.
The method
Infrastructure Intelligence
Infrastructure Intelligence grades every pipe section, weights vertical stacks by the floors they serve, and gives boards and managers a prioritized plan they can build into the reserve study.
