Verified Project Delivery Records — 30+ Countries, Every Structure Standing

2,000+ tonnes of welded pipe trusses for the Tarbela hydropower project were fabricated in Xuzhou and shipped through Karachi port in three shipments, each matched to the agreed fabrication schedule down to the week. Every truss shipped with a complete documentation pack: material test certificates traceable to heat numbers, UT reports on the full-length longitudinal welds, and shop drawings in English that the client’s consultant approved without a single round of clarifications.

When the erection crew needed advice on lifting 36-meter trusses in high wind conditions, our site support team joined daily coordination calls and issued a revised two-stage lifting sequence within 48 hours. The structure was closed out on schedule, and the same client referenced us for the next phase. Dispatch photos, loading plans, and inspection records from this project remain available in our archive for client-side engineers.

The Jinrui New Energy coke plant complex covers 250,000 square meters, and the structural steel budget was one of the largest line items of the whole investment. Our quotation broke the scope into steel material, fabrication labor, surface treatment, packaging, and inward freight — every line item open for audit — and that transparency held through the contract: when steel plate prices moved, the mill price change was shown with source documentation instead of a quiet adjustment to a lump sum.

Members were inspected at three checkpoints — cutting, assembly, and after blast-cleaning — and dimensional deviations were photographed and logged before galvanizing. Across the first 5,000 tonnes, three minor issues were identified, all corrected before shipment. The plant is now operating, and a phase-two scope is under discussion with the same owner. Inspection records for each checkpoint are filed against the member mark numbers and can be provided on request.

For the airport terminal structural package — 1,200 tonnes of columns, trusses, and purlins shipped to Central Africa — export packaging and documentation were treated as part of the deliverable, not an afterthought. Every member was individually wrapped with VCI anti-corrosion film, bundle labels matched the packing list item by item, and the customs file included certificate of origin, packing lists, and mill certificates in a form the client’s clearing agent could process without follow-up calls.

Two of our engineers flew to Brazzaville for the first three weeks of erection and worked with the local crew, training them on the high-strength bolt tightening sequence and the grid lifting procedure. Support continued until the local team could erect an entire bay without supervision. The roof closure was completed ahead of programme, and the anti-corrosion and packaging specifications from this export are retained as executed-project records.

The 77,000 m² heavy truck assembly workshop had to be delivered inside a 15-month window with the production line installation following our erection crew bay by bay — a schedule with almost no float. The double-layer bolted sphere grid roof over the main assembly hall, roughly 150 m by 400 m in plan, was designed and supplied by us, and the fabrication sequence was managed so that each batch of members arrived on site in the order the crew erected them, not in production order.

Node coordinates were verified against the shop drawings on a CMM before shipment, which is why the ball nodes mated first time, bay after bay. The roof was closed, handed over to the cladding contractor, and equipment installation started exactly on programme. The fabrication-sequence plan and CMM verification reports for this workshop are retained and can be presented as reference evidence.

The new-energy vehicle stamping and assembly halls had to clear 85 meters without intermediate columns — the width the production line and its logistics corridor demand. At that span the double-layer grid structure is a deflection problem as much as a strength problem; tolerances on node geometry are unforgiving. We handled design coordination with the client’s consulting engineer directly, and the full-penetration butt welds passed 100% of ultrasonic testing, with welders qualified to the EN 1090 procedure requirements specified by the client.

Because the grid was prefabricated in large sub-assemblies, approximately 60% of the 85,000 m² roof was erected in pre-assembled panels rather than piece by piece, cutting site welding by thousands of joints and shortening the critical path by about a month. Production trials started on schedule, and the structure has carried full plant loads through two typhoon seasons without a single reported issue. UT records and the pre-assembly lifting plan are part of the project archive.

A high-speed railway station cannot stop operating while its roof is being built. The 75-meter span grid dome over the Xuzhou station hall was erected above a live concourse, which made every lifting plan a safety review in itself. The same company held the contracts for manufacturing and site installation, giving the client a single accountable party for the interface between shop tolerance and site fit.

Construction was planned around low-traffic night windows, and temporary support towers were removed progressively as the dome carried its own weight. Site safety management recorded zero incidents over the entire roof erection, and every weld was inspected before the support towers moved. The completed structure passed final acceptance on the first inspection with no non-conformities. The lifting-sequencing plan and acceptance records for this dome are retained in our project archive.
