Dubai $953M Fourth Corridor | Machinery Shortage Behind 80km

On September 16, 2026, Sheikh Hamdan bin Mohammed, Dubai’s Crown Prince and Chairman of The Executive Council, approved the New Fourth Corridor project. The corridor runs about 80 kilometers from Al Faya Road in Abu Dhabi to Al Shanouf Road in Sharjah, crossing Dubai on a 12-lane alignment. The first phase alone carries an estimated cost of AED 3.5 billion, roughly $953 million.

For construction contractors across the UAE, the approval opens a multi-year equipment sourcing cycle. Choosing which channel, machine type, model and budget tier of construction machinery for Dubai to lock in now is a question every bid team is already asking.

What the Dubai Fourth Corridor Actually Is

The corridor is Dubai’s third major inter-emirate highway after Sheikh Zayed Road and Sheikh Mohammed bin Zayed Road. It connects three emirates: Abu Dhabi, Dubai and Sharjah. The full 80 km alignment starts at Al Faya Road in Abu Dhabi and ends at Al Shanouf Road in Sharjah.

The project is delivered in two phases. Phase one runs from Al Shanouf Road to Dubai-Al Ain Road and carries the AED 3.5 billion price tag, Phase two extends the link toward Abu Dhabi. RTA Dubai said the corridor is designed as a 12-lane highway with separated truck lanes, toll gantries and smart traffic systems.

On September 16, 2026, RTA approved implementation but has not yet awarded construction contracts. The engineering package is large. The full project includes 72 bridges, 17 tunnels and 45 stormwater culverts. The bridges carry the highway over wadis, interchanges and local roads. The tunnels take traffic under built-up areas. The culverts handle Dubai’s rare but heavy flash rainfall.

How Large Infrastructure Projects Usually Source Machinery

The project is a decade-scale infrastructure program not a small road widening, Megaprojects rarely buy every machine new. Fleet owners typically run three tracks in parallel: new purchases for core long-haul units, rental for peak-season demand, and second hand construction machinery for mid-specialist roles where owning the asset beats renting it over a multi-year build.

Three forces push contractors toward the third track. First, a used unit costs 30 to 70 percent below a new machine of the same brand, which frees working capital for fuel, operators and overtime. Second, Chinese yards hold ready stock, so a unit can load within days rather than wait six to twelve months on a factory queue. Third, on a 72-bridge job, the contractor needs not ten machines but ten machine types, and not every type justifies a brand-new purchase that will sit idle once the project closes.

What Used Construction Machinery the 80 Kilometer Highway Needs

The terrain between Abu Dhabi and Dubai is flat desert plain, ground conditions are mostly sand and sabkha.That will pull in earthmovers, bridge cranes, concrete pumps and drilling rigs from yards across the region. The tonnages below follow typical desert highway design. Final span, pile length and girder weight will follow the contractor’s detailed design when tender documents are released.

Earthworks: 80 km of cut and fill

Eighty kilometers of desert alignment means millions of cubic meters of cut and fill. A contractor usually splits the corridor into three to five work fronts, each running on its own schedule. On each front, crews deploy two to three used excavator Dubai units in the 20 to 25 ton class, typically CAT 320, SANY SY215 or XCMG XE215, to move soil and dig culverts. One used wheel loader Dubai with a 5 to 6 cubic meter bucket stockpiles aggregate and feeds the asphalt plant. Two dozers and one motor grader finish the sub-base across each front.

Bridges: 72 structures, wide decks

A 12-lane highway carries deck widths of 45 to 55 meters. Most overpasses use 30-meter precast box girders, each weighing 80 to 120 tons. The standard method is two used truck crane UAE units in the 50 to 80 ton class lifting in tandem on each bridge station, or one 100 to 130 ton unit for heavier spans. With 72 bridges spread along 80 kilometers, contractors usually mobilize three to four crane teams working in rotation. SANY STC800 and XCMG QY130K are common in the Gulf.

Tunnels, culverts and piling

Forty-five stormwater culverts use one to two 15 to 20 ton mini-excavators per trenching crew. The 17 urban tunnels need concrete placed at reach: one used concrete pump truck UAE in the 37 to 48 meter boom class pours each portal, supported by four to six used concrete mixer truck UAE units cycling between the batching plant and the pour. Bridge foundations on desert sand usually run 20 to 35 meters deep with 800 to 1200 mm diameter bored piles, matched to a used rotary drilling rig in the 220 class, such as SR220 or XR220, with one rig per bridge pier group.

Work package	Ground / structure	Typical machines	Tonnage / spec
Earthworks, 80 km	Desert sand, cut and fill	Excavator, wheel loader, dozer	20-25 ton excavator; 5-6 m³ loader
72 bridges, 45-55 m decks	30 m precast box girders, 80-120 t each	Twin truck cranes, or single heavy crane	50-80 ton tandem; 100-130 t single
17 urban tunnels	Shallow cut-and-cover	Concrete pump truck	37-48 m boom
45 stormwater culverts	Trenching in desert sand	Mini-excavator	15-20 ton
Bridge and tunnel piles	Sand/sabkha, 20-35 m deep, Ø800-1200 mm	Rotary drilling rig	SR220 / XR220 class

Used Construction Machinery Is Becoming More and More on Large Projects

This is not a bargain hunt, it’s a portfolio decision. Core earthmovers that run 6,000 hours a year may be bought new. Bridge cranes, concrete pumps and drilling rigs that move between short bridge stations, or that finish their useful life at project end, are usually better bought as used units in inspected condition.

Take one typical machine:A 50 to 80 ton truck crane, the workhorse for placing 30-meter box girders. A new unit costs roughly USD 220,000. A three-to-five-year-old Chinese used unit in inspected condition costs about USD 95,000. Over 36 months, fuel and maintenance run USD 54,000 either way. The new crane depreciates by about 50 percent, or USD 110,000. The used crane depreciates by roughly the same 50 percent of its lower purchase price, or USD 47,500.

Rental sits in between. A truck crane in the UAE costs USD 6,000 to 9,000 per month, or USD 252,000 over 36 months with no residual. For a machine on site over 18 months, buying used nets roughly USD 107,500 in total cost versus USD 253,000 in rental. That gap is what pushes fleet owners toward used purchase on long projects.

Scale the math. A contractor buying one 22-ton excavator, one 80-ton truck crane and one 47-meter pump truck as used spends about USD 300,000. The same package new would cost USD 670,000. The saving funds two extra operator crews for a year, or covers the first round of spare parts across the fleet.

Machine class	New machine (USD)	Used Chinese unit (USD)	Saving	3-year residual
20-25 t excavator	110,000-140,000	45,000-65,000	55-60%	~55% of used price
50-80 t truck crane	180,000-260,000	80,000-120,000	55-60%	~50% of used price
100-130 t truck crane	350,000-500,000	160,000-240,000	55-60%	~55% of used price
37-48 m concrete pump truck	380,000-550,000	160,000-230,000	55-60%	~45% of used price

Why Chinese Used Machines Fit the Middle East

SANY, XCMG and Zoomlion already run large fleets across the UAE, Saudi Arabia and Qatar. A used SANY truck crane UAE or a used XCMG excavator Dubai arrives as the same model crews already run, not as an unknown import.

Chinese used construction machinery Middle East buyers pay roughly 40 to 50 percent less than for a new European machine, and 20 to 30 percent less than for a used Japanese unit. Freight from Shanghai, Lianyungang or Qingdao to Jebel Ali runs 25 to 35 days.

SANY and XCMG truck cranes dominate the 50 to 130 ton segment in the Gulf. Zoomlion concrete pump truck used units are widely used on high-rise and infrastructure pours. Parts move through regional distributors in Jebel Ali, Riyadh and Doha.

Shipping Used Machinery to Jebel Ali

Most buy used construction machinery China orders sail from Shanghai, Lianyungang or Qingdao. Ro-Ro works for wheeled units; excavators and drilling rigs go on flat-rack or breakbulk.

Payment stays straightforward: dollar T/T and irrevocable letters of credit both work. The exporter prepares invoice, ownership certificate, export declaration and bill of lading. A pre-shipment inspection report smooths customs.

Imachine holds close to 100 used construction machinery export to UAE ready units in Changsha, each with an inspection report, nameplate photos and a working video.

Questions Dubai Buyers Actually Ask

Is this project tendered or directly awarded?

Following RTA’s standard practice on comparable projects such as the Latifa bint Hamdan Corridor and Al Meydan Street development, contractors will be selected through a public tender, likely over the next 3 to 6 months.

Can a Chinese used machine supplier bid directly for RTA work?

Not directly. RTA awards to main contractors, who then source equipment through their own supply chain. Used machinery suppliers support the contractors who win the tender.

What emission standard does the UAE require for used machines?

Most used construction machinery Tier 2 or Tier 3 units clear UAE customs. Confirm the exact stage with the clearance agent before shipment.

When will the best 80-ton truck cranes and 22-ton excavators move?

After contract award, typically 2 to 4 months before site mobilization. Buyers who lock in stock 6 months early avoid the rush.

Do Chinese brands have local service in Dubai?

Yes. SANY, XCMG and Zoomlion run service centers in Jebel Ali. Common spares also ship with the machine.
