In a previous post HERE, we discussed the variations in CFD firehouse designs constructed under the Alive 21 program. The stations built include Engines 18, 38, 63, 70, 84, 88, 102, 121, Air/Sea Rescue, and Engine 109, which is still under construction. Several design differences were noted, such as two similar layouts that differed in the inclusion of a hose tower, the shape of the roofline, and the amount of glass on the top of the apparatus bays. A third design is now being used for Engine 109’s new station and also for Engine 16’s new facility. Interestingly, Engine 16’s building marks the start of what the City of Chicago Public Building Commission (PBC) calls the first “Prototype B†engine house—though it's worth noting that Engine 109 uses the same design.
Each firehouse has a different square footage based on the specific needs of the assigned company. For example, Engine 102’s house spans 14,000 square feet, while Engine 121’s is larger at 18,000 square feet. These differences account for office space, meeting areas, and training facilities. Engine 16’s new station will be even bigger at 18,500 square feet, including space for a Haz-Mat unit, storage, and offices for the EMS Field Division South.
The rear entry to the three apparatus bays originally featured two wide doors, a design used for Engines 38, 63, 84, and 88. Later, this was updated to include three single-width doors at the back, matching the front entrance. Stations for Engines 18, 70, 102, and 121 now have this three-door configuration.
The Chicago Public Building Commission website provides links to completed Fire Station projects HERE and ongoing projects HERE. These pages include photo galleries showing the progress of each construction site.
Some stations, like Engine 88, feature a hose tower, while others, such as Engine 102, do not. Engine 121’s station stands out with its unique landscaping and large solar panels on the roof. Additionally, the orientation of some buildings has been adjusted—like Engine 84’s station, where the apparatus exits from the west side, even though the watch room is on the east. This shows how design elements can vary based on location and functionality.
Overall, the Alive 21 program has brought a range of innovative and functional firehouse designs to Chicago, reflecting both practical needs and aesthetic considerations.
PP/PE Pipe Production Line
The PE Pipe Production Line can be categorized based on the pipe diameter and application.
1. PE Water Supply Pipe Production Line
This production line can produce pipes with a diameter range of 16mm to 1200mm. For example, the XDC-HDPE63 model can produce pipes with a diameter of 16-63mm, with a maximum output of 200 kg/h.
It is designed for high-speed production and features a stable and simple operation. The pipes produced have smooth inner walls, extremely low friction coefficients, good flexibility, high impact strength, and corrosion resistance.
Widely used in municipal water supply systems, building water supply systems, and industrial water treatment systems.
2. PE Gas Pipe Production Line
Similar to the water supply pipe production line, it can produce pipes with a diameter range of 16mm to 1200mm. The XDC-HDPE160 model, for instance, can produce pipes with a diameter of 63-160mm, with a maximum output of 300 kg/h.
The production line is equipped with advanced extruders and precision die heads to ensure the quality of the pipes. The pipes have good flexibility, high impact strength, and corrosion resistance.
Used for gas transportation piping systems in various industries.
3. PE Communication Pipe Production Line
This production line is designed to produce pipes with a diameter range of 16mm to 1200mm. The WR-630 model can produce pipes with a diameter of 250-630mm, with a maximum output of 1100-1200 kg/h.
It features a high degree of automation and optimized screw structure, ensuring stable production efficiency. The pipes produced have excellent corrosion resistance, compression resistance, and impact resistance.
Suitable for power communication systems.
4. PE Silicone Core Pipe Production Line
This production line can produce pipes with a diameter range of 16mm to 1200mm. The pipes have a silicone solid lubricant on the inner wall.
The silicone core pipe is widely used in optical cable communication network systems for railways and highways. It has the advantages of being moisture-proof, insect-proof, anti-corrosion, and anti-aging.
Used in optical cable communication network systems.
