Questions & Answers from A-Z about XIZI smart parking

As the leading smart parking contractor in Vietnam with over 16 years of experience, Viet Chao takes pride in being the exclusive strategic partner distributing XIZI intelligent parking systems – advanced parking technology from Japan. The superior quality of our products has been proven through dozens of large-scale projects and nearly 5,000 smart parking spaces deployed nationwide from North to South.

Since when has Viet Chao been installing XIZI smart parking systems?

Viet Chao proudly stands as the pioneer in the intelligent parking sector in Vietnam since 2008. Our first milestone was the supply and installation of an automated parking system at BIDV Tower, 194 Tran Quang Khai, Hanoi (completed in 2009). Remarkably, after more than 16 years of continuous operation, the parking system at this project remains fully functional, operating smoothly and reliably, with only one relay component ever needing replacement throughout its entire service life.

What is the feedback from investors/project owners regarding the puzzle-type intelligent parking systems?

Feedback from investors and project owners who have installed and operated Viet Chao’s XIZI puzzle-type parking systems is nearly 100% positive. Our clients consistently praise the systems for their outstanding stability, long-term reliability, and ease of use.

Puzzle-type and simple lift-type parking systems rarely experience malfunctions when operated in accordance with guidelines and subjected to regular scheduled maintenance. For example, at the HACC1 Complex project (Le Van Luong, Hanoi), after 5 full years without any maintenance or service contract, the system only encountered its very first vehicle jamming incident — at which point Viet Chao was called for emergency support.

We always strongly recommend that investors carry out periodic preventive maintenance to ensure the XIZI intelligent parking system operates stably and reliably throughout its designed lifespan of 15–25 years. Nevertheless, even in cases where regular maintenance has been neglected, the XIZI system continues to demonstrate exceptional durability — often described by clients as “built like a tank.” This superior robustness clearly sets XIZI apart from locally fabricated systems or non-integrated products available in the market, reaffirming its top-tier quality and engineering excellence.

Over the years, thanks to valuable feedback from investors and our constant willingness to listen and improve, Viet Chao’s products have continuously evolved and reached higher standards. For example, when clients suggested enlarging the text on guidance signs for better visibility, we immediately adopted the recommendation and upgraded all signage to be clearer and more user-friendly. Specifically, with a strong commitment to real-world usability, we increased the signboard size from 1 m to 1.8 m — significantly enhancing the overall user experience.

Are the pallets in the puzzle-type parking system electro-galvanized or hot-dip galvanized?

The pallets used in the semi-automated parking systems supplied by Viet Chao are treated exclusively with hot-dip galvanizing. This process creates a thick protective coating of 60–200 microns, providing comprehensive corrosion and rust resistance even in harsh outdoor environments.

Structural columns and beams are typically finished with high-quality electrostatic powder coating, while in some projects we combine both hot-dip galvanizing and powder coating for maximum durability.

Viet Chao strictly refuses to use electro-galvanizing (cold galvanizing), despite its much lower cost, because its coating thickness is only 5–25 microns (roughly 1/10 that of proper coatings), making it highly prone to scratching and rapid corrosion.

What is the equipment failure/replacement rate of Viet Chao’s intelligent parking systems?

XIZI smart parking stand out globally for their exceptional reliability, with an equipment replacement rate of only 0.1% to 0.3% — far below the global industry average of 3%–8%.

Real-world proof can be seen in projects such as BIDV Tower at 194 Tran Quang Khai (over 16 years), Masterise Thao Dien (nearly 10 years), HACC1 Complex on Le Van Luong (9 years), etc. In these long-running installations, the only components ever replaced have been minor, inexpensive, and easy-to-maintain items such as sensors and limit switches — minimizing both resource waste and operating costs for the investor.

How does the AGV system work? What happens when multiple vehicles enter or exit at the same time?

The driver simply drives the vehicle to the designated handover zone. The AGV (Automated Guided Vehicle) will then automatically transport and store the car in its pre-programmed parking space.

We carefully calculate the required number of AGVs and their operating speed based on the project’s peak traffic flow to completely eliminate congestion and waiting times. The system is customized for each investor’s specific throughput requirements, ensuring smooth simultaneous entry and exit even during rush hours.

Is the AGV technology regularly updated? Are there any recurring fees?

Viet Chao fully commits to transferring complete technology to the investor and providing lifetime automatic software/firmware updates at only a one-time fee — with no recurring or hidden costs.

Our engineering team is directly trained and certified by XIZI, ensuring the AGV system always runs on the latest technology version for smoother, quieter, and more reliable operation throughout its service life.

What is the required clearance between the parking system and basement structural columns?

The ideal clearance is 150–175 mm. However, we offer full flexibility to suit each project’s actual conditions — for example, at the smart parking project in Binh Duong, we successfully installed the system with only 100 mm clearance.

With extensive installation experience, we can adapt to almost any column layout. Where there are no obstructions (walls or columns), the system can even be placed flush against the structure without affecting vehicle door opening.

What are the fire protection requirements for mechanical parking systems?

XIZI systems comply fully with Vietnamese and international fire codes without requiring any extraordinary measures beyond standard practice:

Sprinklers are installed along both sides of the system and beneath the second-level pallets (utilizing existing ceiling sprinkler heads). Unlike many competitors who demand a sprinkler head in front of/behind every single pallet, our certified design achieves full fire safety compliance with far fewer heads — delivering maximum protection while significantly reducing installation and material costs for the investor.

How long does it take to supply and install a XIZI intelligent parking system?

Immediately after contract signing, we place the order directly with XIZI factory. The standard timeline is:

• 70 days manufacturing at XIZI factory
• 20 days sea freight + customs clearance to Vietnam
• On-site installation & commissioning (depends on system size)

Real example: The XIZI smart parking project at Dream Home, Vinh (nearly 55 parking spaces) was fully supplied, installed, tested, and handed over in under 23 days — demonstrating our ability to deliver extremely fast deployment without compromising quality and safety.

Are Viet Chao’s intelligent parking systems covered by insurance?

Yes, every XIZI smart parking system supplied by Viet Chao is fully covered by a comprehensive insurance policy with liability coverage of up to VND 1,000,000,000 per incident. The policy includes:

• Physical damage coverage: Compensation for any accidental damage to vehicles caused by unexpected incidents during system operation (collision, structural failure, or equipment malfunction).
• Third-party liability coverage: Protection for all related parties in the event of personal injury or property damage within the parking area (excluding contractor’s own employees).

After the standard 2-year warranty expires, how are incidents caused by the system handled?

Viet Chao offers investors two flexible post-warranty maintenance contract options:

• Standard Maintenance Contract Our technical team performs all scheduled preventive maintenance and repairs. In case replacement parts are required, we provide a detailed technical report and transparent cost quotation for the investor’s approval before proceeding.
• All-inclusive Comprehensive Maintenance Contract Viet Chao assumes full responsibility for all maintenance and repair costs, including unlimited parts replacement, throughout the contract term — giving investors complete peace of mind and 100 % budget certainty.

Do Viet Chao’s intelligent parking systems support green and sustainable?

Absolutely. XIZI systems are designed with sustainability in mind:

• Integrated drainage channels on the upper level prevent water accumulation, minimize corrosion risk and significantly extend equipment lifespan.
• XIZI systems come standard-ready with built-in electric vehicle (EV) charging stations at each parking space — delivering superior user convenience while actively promoting eco-friendly transportation and contributing to the development of green, sustainable urban environments.

What is the required floor height for the PSH2 system?

Depending on the investor’s needs and the specific characteristics of each project, Viet Chao will propose the most space-efficient solution. Typical clear height requirements for a 2-level PSH system (PSH2) are shown below:

Are on-site technicians available 24/7 to handle incidents?

Yes. Viet Chao maintains a dedicated 24/7 standby maintenance team assigned to each geographic region. Technicians are not required to stay permanently on site but are on constant call and ready to respond immediately to any issue or emergency.

Our highly qualified technicians undergo regular monthly and quarterly training conducted directly by XIZI experts and our in-house senior engineers, ensuring fast, accurate diagnosis and resolution of any problem.

In the event of an incident, what is the maximum response time for a technician to arrive at the project site?

We guarantee that our technical team will arrive on site within a maximum of 60 minutes from the moment the incident is reported.

With a comprehensive local spare-parts warehouse always in stock, Viet Chao ensures rapid and effective resolution — further reinforcing our position as Vietnam’s leading smart parking contractor.

What happens if a component fails and needs replacement?

Viet Chao maintains a large local stock of common spare parts (sensors, switches, relays, pallets, control boards, etc.) for immediate replacement.

For major components such as motors or special gearboxes that are not kept in daily stock, we offer two delivery options to suit the investor’s urgency:

• Air freight: 5–7 days
• Sea/land freight: 15–20 days

What is the monthly electricity consumption per parking block?

Average power capacity per typical mechanical parking block (PSH system): ≈ 4 kVA

• Lifting motor: 2.2 kW
• Sliding motor: 0.2 kW

How often is the system required to undergo official safety inspection?

• First 10 years of operation: once every 2 years
• After 10 years: once every 1 year.

Who is responsible for inspection costs after the warranty period?

• The initial acceptance inspection (before handover) is fully included in our contract price.
• All subsequent periodic inspections (starting from the 2nd inspection) are the responsibility and cost of the investor/building management. Viet Chao provides full documentation support and can arrange the inspection on behalf of the investor if requested.

Who provides the warranty for the system — Viet Chao or XIZI?

The system is jointly warranted by both XIZI (the manufacturer) and Viet Chao as the exclusive strategic partner and authorized service provider in Vietnam.

What international quality certifications does XIZI hold?

XIZI is one of the very few global manufacturers that has achieved full CE Marking certification for complete puzzle-type parking systems from 2 up to 8 levels — a distinction almost no competitor can match. Obtaining full-system CE certification requires extremely rigorous testing of safety, structural integrity, electrical systems, and emergency functions; most other brands only certify 2–4-level systems, if at all.

Additional prestigious certifications and awards held by XIZI include:

• Full quality and safety certification from TÜV Nord (Germany)
• The highly coveted Red Seal Certification issued directly by the Zhejiang Provincial Government (known for its exceptionally strict auditing standards)
• National-level commendation and awards from the China National Machinery Industry Association

These credentials unequivocally confirm that XIZI products consistently exceed the highest international standards for safety, durability, and manufacturing quality.
