How We Relocated an HZS120 Concrete Batching Plant from Saudi Arabia to Kenya

Relocating an HZS120 concrete batching plant from Jeddah, Saudi Arabia to Nairobi, Kenya involves marine shipping across the Red Sea and Indian Ocean, inland trucking from Mombasa to Nairobi, Saudi customs export clearance including Mohammadi certification, Kenyan import inspection, and full mechanical/electrical re-installation and commissioning on-site. Here is exactly how we did it —with the actual timeline, costs, setbacks, and solutions that made this cross-border relocation successful.

What Was the Client's Situation?

In early 2024, a mid-sized Kenyan construction firm approached us with a specific problem. They had won a tender for a 14 km section of the Nairobi–Mombasa highway upgrade —a KENHA-funded project requiring 45,000 m³ of C30/C40 concrete delivered over an 18-month period. They already owned an HZS120 stationary plant sitting idle at a completed project site in Jeddah, Saudi Arabia. The machine was eight years old, well-maintained, and had produced roughly 180,000 m³ over its life. But it was parked on a lot in the Al Khumrah industrial area, 25 km south of Jeddah's Islamic Port.

Buying a new HZS120 locally in Kenya would have cost them approximately $140,000—160,000 including delivery and basic commissioning. Their budget for this project simply did not stretch that far —the highway margin was tight at roughly 12%, and every dollar mattered. Moving their existing plant from Saudi to Kenya was the only financially viable option.

The client gave us a target: have the plant operational in Nairobi within 45 days from the date of signed contract. We knew from experience that 45 days was aggressive but achievable —provided we avoided the usual bottlenecks in Saudi export customs, Red Sea shipping schedules, and Kenyan port clearance.

How Did We Plan the Relocation?

Our relocation process always starts with a physical pre-inspection. I flew to Jeddah with a two-man team three days after the contract was signed. We spent a full day at the site documenting every component of the HZS120.

The plant consisted of:

• Four-bin cold aggregate feeder (6 m³ per bin)
• Belt conveyor (18 m length)
• Twin-shaft compulsory mixer (JS2000, 2 m³ discharge capacity)
• Cement silos × 4 (100 T each) with screw conveyors
• Control room with Siemens S7-1200 PLC and cabinet
• Pneumatic system with air compressor and piping
• Water metering and additive dosing systems
• Structural steel frame, platforms, catwalks, and handrails
• Approximately 450 m of electrical cabling

We performed a detailed condition assessment:

• Mixer blades and liners: 60% worn —recommended replacement at reinstallation
• Belt conveyor: Good condition, three worn return rollers
• Cement silo filter cartridges: Needed replacement —Jeddah's humidity had caked two of them
• PLC and electrical: Fully functional, but all labels were in Chinese (original manufacturer), so we photographed every terminal block and circuit breaker panel for reconnection reference
• Structural steel: Surface rust on about 15% of components —manageable with grinding and repainting

We created a detailed packing list: 47 line items spanning 8 shipping containers and 2 flat-rack units. The total calculated volume was approximately 1,280 m³. By optimizing the nesting of smaller components inside the main mixer frame and silo sections, we reduced the container count from an estimated 11 down to 8 —saving roughly $3,600 in shipping costs.

The pre-inspection also uncovered a cracked weld on the main mixer frame support leg. We caught it because we use dye-penetrant testing on all structural welds during pre-inspection. Had this gone unnoticed, it could have caused a catastrophic failure during lifting or transport. We weld-repaired it on-site in Jeddah before any disassembly began.

How Did We Plan the Logistics Route?

The chosen route was:

1. Jeddah Islamic Port —28 km truck transport from the storage yard
2. Sea freight: Jeddah to Mombasa —2,780 nautical miles via the Red Sea, Gulf of Aden, and Indian Ocean
3. Mombasa Port to Nairobi: 485 km via the A109 highway (Nairobi–Mombasa corridor)

We booked a 20-foot container vessel on the MSC line that sailed every Tuesday from Jeddah. Transit time was scheduled at 9 days, but we included 3 days of buffer for Suez Canal traffic or weather delays. In practice, the crossing took 11 days due to a sandstorm that delayed loading in Jeddah by 48 hours.

What Challenges Did We Face?

Challenge 1: Saudi Export Customs and Mohammadi Certification

Saudi Arabia requires a Mohammadi certificate (also called a Saudi Original Certificate) for the export of used industrial machinery. This certifies that the equipment is not stolen, not subject to any local liens, and not classified as restricted or dual-use goods. The process involves:

• Submission of the original purchase invoice or bill of sale (the client had lost theirs —we had to track down the original dealer in Qingdao, China for a duplicate)
• Inspection by a Saudi customs-approved surveyor at the storage location
• Notarization from the Saudi Chamber of Commerce —which cost SAR 1,200 (?320)
• Stamp from the Ministry of Industry and Mineral Resources confirming the machinery is surplus and exportable

This process took 9 days instead of the planned 5 because the Chamber of Commerce required a physical document that had to be couriered from the dealer in China. We learned a hard lesson: always ask for original purchase documentation before the pre-inspection trip.

Challenge 2: Disassembly in Jeddah's Summer Heat

We started disassembly in late May. Jeddah in May hits 42°C ambient with 60%+ humidity. Our team of four (two of our technicians plus two local helpers we hired in Jeddah) worked from 5:00 AM to 11:30 AM, then stopped through peak heat, then resumed 3:30 PM to 7:00 PM. We rotated tasks to minimize continuous exposure.

Despite precautions, one of the local helpers suffered mild heat exhaustion on Day 3. We had a first-aid station with IV saline on-site as a precaution —standard for all our Middle East project sites. He recovered within 24 hours, and we adjusted hydration breaks to every 45 minutes after that.

Challenge 3: Port Congestion in Jeddah

Jeddah Islamic Port handles over 4 million TEUs annually and during mid-2024 there was a backup caused by a terminal equipment shortage. Our containers were originally booked for a June 3 sailing but got rolled to June 8. This added 5 days to the timeline before the vessel even departed.

We mitigated this by having our freight forwarder keep daily pressure on the shipping line, and by pre-paying demurrage insurance so we wouldn't lose our slot. The roll cost us $780 in additional container yard storage fees, but the alternative —waiting another week for the next vessel —would have been far worse.

Challenge 4: Kenyan Import Clearance

Kenya's import process for used machinery requires a Pre-Export Verification of Conformity (PVoC) certificate issued by SGS or Intertek in the country of origin. We had arranged this in Saudi before shipping. However, the Kenya Bureau of Standards (KEBS) flagged our cement silos as "pressure vessels" and required additional inspection documentation showing they were not designed for pressurized storage. We had to submit the original manufacturer's drawings showing atmospheric design pressure only. This took three days to resolve while the containers sat at Mombasa Port accumulating storage charges —$185 per container per day after the first 5 free days.

Total port storage charges came to $4,440. We now always include a customs contingency of at least $5,000 in our client quotes for Kenyan arrivals.

Challenge 5: Road Transport During Rainy Season

The A109 highway between Mombasa and Nairobi is generally good tarmac, but we hit the start of the long rainy season in late June. A 12 km section near Mtito Andei had flash flooding that forced a 36-hour road closure. Our trucking company rerouted via Voi —an additional 80 km and $600 in extra fuel and driver allowance. The load arrived at the Nairobi site intact, but two days behind schedule.

How Did We Execute the Relocation Step by Step?

Here is the actual timeline from contract signing to commissioning:

What Was the Final Result?

The HZS120 was commissioned on Day 52 —seven days past the original 45-day target, but well within the acceptable range given the customs and weather delays we encountered. The client was understandably anxious during the two-week period when the containers were delayed, but once the plant was running they were satisfied with the outcome.

Project cost breakdown:

• Pre-inspection and travel (2 technicians, 4 days): $3,200
• Local labor in Jeddah (2 helpers × 12 days): $2,400
• Consumables: cutting discs, grinding wheels, paint, solvents, packaging materials: $1,850
• Container trucking to Jeddah Port: $1,600
• Sea freight (8 × 20ft containers + 2 flat racks): $9,500
• Mohammadi certification and Saudi customs clearance: $2,100
• Marine insurance (0.35% of declared value on $65,000): $228
• KEBS PVoC and Kenyan import duties (16% VAT on CIF value): $8,200
• Mombasa port handling + storage charges: $5,440 ($1,000 handling + $4,440 storage)
• Road transport Mombasa ?Nairobi (3 trucks): $4,800
• Foundation materials and concrete for new slab: $2,500
• Installation team (3 technicians × 15 days): $6,750
• New mixer blades, silo filter cartridges, return rollers: $3,200
• Miscellaneous (accommodation, permits, communication): $1,832
• Total project cost: ~$53,600

The client paid us a fixed relocation fee of $45,000. We absorbed approximately $8,600 in cost overruns —the customs storage fees, the trucking reroute, and the additional labor from the disassembly delays in Jeddah. This was a calculated decision: we had a signed agreement for the $45,000 fixed price, and eating the overrun preserved the client relationship. They have since referred us to three other contractors in the East African market.

Against a new-equipment cost of approximately $145,000 delivered in Kenya, the client's total all-in cost was approximately $53,600 —a saving of over $91,000. More importantly, the plant was running on a timeline that allowed them to start supplying concrete for the highway foundation layer only four weeks behind the original project schedule, which the contractor accepted given the compelling cost savings.

As of June 2026 —18 months after commissioning —the plant is still running at approximately 95% of its rated capacity. The only significant issue was a mixer motor bearing failure in month 14, which we replaced under our 12-month workmanship warranty. The client reports total concrete production of roughly 62,000 m³ to date.

What Were the Key Lessons from This Project?

After relocating over 50 concrete plants across the Middle East, Africa, and Central Asia, this project reinforced several principles we already knew —and taught us a few new ones.

• Never skip the pre-inspection. The cracked weld we found on the mixer frame would have caused a serious incident during lifting. Dye-penetrant testing on structural welds costs about $150 in materials and can save you a catastrophic failure.
• Get original purchase documents before you leave for site. The week we lost tracking down a duplicate invoice from the Chinese manufacturer could have been avoided with a single email before the contract was signed.
• Build 10—4 days of buffer into your timeline for Saudi export paperwork. Saudi customs and the Chamber of Commerce operate on their own schedule. Mohammadi certification is not a 24-hour process, and expecting it to be one will cause delays.
• Always budget $5,000+ for Kenyan port contingency. Between KEBS inspection delays, container storage charges, and port handling fees, the real cost of clearing a multi-container shipment through Mombasa is almost always higher than first estimates suggest.
• Photograph every electrical connection before disconnecting. We took 340 reference photos in Jeddah and used them extensively during reconnection in Nairobi. On a plant this size, tracing a mislabeled wire through 450 m of cabling can cost a full day of troubleshooting.
• Clients remember how you handle problems, not how smoothly the plan goes. We went $8,600 over budget on a fixed-price contract. But the client got their plant running, and we now have a foothold in the East African market that has generated three referral projects worth a combined $87,000 in revenue.

Every relocation is different —different countries, different plant configurations, different sets of paperwork. But the fundamentals are always the same: thorough inspection, meticulous documentation, honest communication with the client, and a realistic buffer for the things you cannot control. If you are considering moving a plant between continents, start with a proper site assessment, budget for delays, and pick a partner who has done it before.
