Construction has officially begun on a new 1.1 million-square-foot industrial warehouse in the Phoenix metropolitan area as developers move to address a shortage of large-scale logistics space. The project, known as GO|99 North, is being built in Tolleson and is expected to strengthen the West Valley’s role as a major distribution and industrial hub.
Project
Willmeng Construction recently broke ground on GO|99 North, a Class A warehouse and distribution facility being developed by GO Industrial.
The warehouse will span approximately 1.1 million square feet, making it the largest single building the developer has brought to market. The speculative project is designed to accommodate future tenants without a pre-existing lease, allowing companies to occupy the space once construction is complete.
Location
GO|99 North is being developed on a 75-acre site in Tolleson’s Estrella Park neighborhood.
The location provides direct access to Interstate 10 within approximately three minutes and is less than five miles from the Loop 202 South Mountain Freeway. This connectivity offers convenient transportation routes for logistics, warehousing, and distribution operations across the Phoenix region and beyond.
| Project Details | Information |
|---|---|
| Project Name | GO|99 North |
| Location | Tolleson, Arizona |
| Site Size | 75 acres |
| Building Size | 1.1 million square feet |
| Developer | GO Industrial |
| General Contractor | Willmeng Construction |
Demand
According to GO Industrial, the development is intended to help address a limited supply of million-square-foot industrial buildings in the Phoenix market.
Company President Robert Guerena said existing warehouses of similar size across Arizona are currently occupied by major retail and e-commerce companies, leaving little available speculative inventory for businesses seeking large-scale distribution facilities.
While some developers have delayed major industrial projects as market conditions stabilize, GO Industrial and Willmeng have continued with construction in response to ongoing demand.
History
GO|99 North follows the success of GO|99 South, another industrial development along 99th Avenue designed by DLR Group and built by Willmeng Construction.
GO|99 South consists of three buildings totaling approximately 1.28 million square feet. The industrial park was sold in 2023 for $165 million, making it one of Arizona’s largest industrial real estate transactions that year.
Willmeng CEO James Murphy said the company is pleased to partner with GO Industrial again after the success of the previous project.
Features
The new warehouse has been designed to support high-volume logistics and distribution operations with modern industrial specifications.
Key building features include:
- 40-foot clear ceiling heights
- 190 dock-high loading doors
- Four grade-level loading doors
- All-concrete 245-foot truck courts
- Parking for approximately 1,200 vehicles
- Space for 113 trucks or trailers
These features are intended to improve operational efficiency for future warehouse users.
Infrastructure
The facility also includes several design elements intended to support long-term industrial operations and future tenant requirements.
Additional specifications include:
| Building Features | Details |
|---|---|
| Roofing | TPO 60-mil membrane |
| Roof Insulation | R-38 |
| Natural Lighting | Clerestory windows |
| Electrical Capacity | 3,600 AMPS, expandable |
| HVAC | Air-conditioning-ready infrastructure |
| Security | Perimeter fence with seven rolling gates |
These systems are designed to provide flexibility for companies requiring modern warehouse infrastructure.
Outlook
The start of construction on GO|99 North reflects continued investment in the Phoenix area’s industrial real estate sector despite broader market adjustments. As demand for large-scale logistics facilities continues, the project is expected to expand the region’s available warehouse inventory and support future business growth in the West Valley.
