Ironpost Works installs Florence 1570 Series cluster box units across Arizona under a single license, single contract scope — engineered concrete foundation, USPS STD-4C compliance, ADA verification, arrow lock coordination, and postmaster sign-off included. No subcontractors. No coordination gaps.
A CBU installation is not a mailbox swap. It is a permitted, engineered infrastructure project. Ironpost Works owns every phase independently — no GC coordination required.
On-site evaluation of existing pad condition, unit count, ADA clearances, USPS access requirements, and soil conditions. Written assessment report provided.
Engineered drawings, permit application, and municipal submittal. Ironpost Works carries the permit independently — no burden on the property owner or HOA board.
Existing unit and concrete removal, debris hauling, and site preparation. Caliche soil remediation included when required by soil conditions.
Engineered concrete pad installation with compaction testing and anchor bolt placement per USPS specifications. New foundation or structural repair depending on existing conditions.
Florence 1570 Series CBU supply and installation. Configuration selected per unit count, parcel volume, and USPS STD-4C compliance requirements for the specific site.
Forward-reach and side-reach measurements per 28 CFR §36.304 on every installed unit. Written ADA verification included in the documentation package.
Postmaster meeting coordination, STD-4C compliance documentation, arrow lock procurement and installation, and delivery activation scheduling.
Complete as-built documentation, compliance photos, postmaster sign-off letter, ADA verification report, and project records for HOA or management files.
We specify the correct configuration for your unit count and parcel volume — not the most available model. All 1570 Series configurations are USPS-approved for centralized mail delivery.
Aging CBU infrastructure, heaved pads, USPS delivery suspension threats, and ADA liability exposure. Ironpost Works manages the full remediation — board approval to postmaster sign-off.
Portfolio-wide CBU assessment and replacement under a single MSA. One licensed contractor, one point of contact, one documentation standard across every property.
New construction CBU specification, pre-construction compliance review, and CO-ready installation. No mail infrastructure delays on your certificate of occupancy timeline.
Ironpost Works carries the mail infrastructure permit independently. No coordination burden on your project team — hand off the scope at contract and receive a complete documentation package at completion.
High parcel volume properties require more than the standard 1–2 locker doors on a 1570 Series CBU. Florence 1590 Valiant standalone parcel locker systems extend capacity for properties where the 1:5 ratio mandates dedicated parcel infrastructure.
Parcel Locker SystemsEvery CBU project follows our 5-Gate Quality Control System (QCS-001). Site assessment, engineering, foundation, installation, and certification — in sequence, documented at every gate. No shortcuts. No assumed sign-offs.
