CASE // 01 BERLIN HUB (BER) • GERMANY 64 MW Hyperscale Data Center Campus

ZERO RED CARDS • 100% FIRST-TIME QUALITY

Hyperscale White Space Chilled Water Distribution & CRAH Headers

Victaulic Grooved DN150–DN400 16.0 Bar Hydrostatic Hold Operating Range: 6°C / 12°C 14-Fitter Crew + Lead 12-Week Delivery

01. The Client Challenge

High-density server hall cooling required massive hydraulic flow within tight spatial clearances under 800mm raised flooring and along overhead seismic ceiling trapezes. The site required zero tolerance for water droplets or particulate debris in active white space zones.

02. Weldkar Assembly & Execution Scope

Autonomous 14-man crew led by an English-speaking supervisor translated complex 3D BIM isometrics directly into field assembly. Weldkar crews installed primary supply/return headers, pre-insulated secondary loops, vibration-isolated CRAH connections, and automated balancing valve arrays with laser-verified ±2mm corridor alignment.

03. HSE Record & Handover Outcome

Flawless 16-bar hydrostatic pressure testing witnessed and signed off by third-party auditors with zero leaks on first pass. Delivered 4 days ahead of contractor commissioning milestone with zero safety warnings or site red cards.

PROJECT // 02 FRANKFURT HUB (FRA) • GERMANY Tier IV Critical Colocation Facility

VID FIREKILL CERTIFIED • ZERO DEFECTS

High-Pressure VID FIREKILL Water Mist & Sprinkler Valve Manifolds

VID FIREKILL High-Pressure Mist Geberit Mapress Stainless 1.4401 140 Bar Proof Pressure Clean-As-You-Go Protocol UL / FM Certified Risers

01. The Client Challenge

Mission-critical server rooms and UPS battery storage halls demanded absolute fire suppression reliability without the catastrophic water damage of conventional sprinkler discharge. Extreme site cleanliness was mandatory to prevent particulate false triggers in optical sensors.

02. Weldkar Assembly & Execution Scope

Specialized pipefitters deployed with certified orbital and manual TIG welding gear pre-fabricated multi-valve manifold blocks and installed Geberit Mapress stainless steel lines. Weldkar assembled sectional deluge valves, test drain stations, and calibrated pressure monitoring instrumentation.

03. HSE Record & Handover Outcome

100% joint integrity verified via pneumatic decay and 140-bar hydrostatic proof testing. The general contractor awarded Weldkar a spotless sign-off certificate with zero open punch-list items.

PROJECT // 03 TESLA ECOSYSTEM • GRÜNHEIDE Advanced EV & Battery Gigafactory

18 MONTHS • ZERO LOST TIME INJURIES (LTI)

Advanced Process Fluids & High-Volume Industrial Cooling Lines

Process Carbon & Stainless DN50–DN300 Compressed Air Ring Mains 18-Fitter Crew + Supervisor Aerial Lifts Up To 12m German UVV Compliant

01. The Client Challenge

A fast-track, dynamic manufacturing campus with shifting production schedules and continuous design revisions. Mechanical installations had to be carried out high overhead in busy active construction bays alongside robotics and electrical trades.

02. Weldkar Assembly & Execution Scope

Weldkar deployed 18 certified pipefitters equipped with our own roll-grooving machines, hydraulic pipe benders, and threading rigs. Our certified scissor-lift operators installed technological cooling loops, high-pressure air headers, and automated valve blocks with rapid daily adaptation to site engineering adjustments.

03. HSE Record & Handover Outcome

Maintained an impeccable 18-month safety record with zero accidents, zero near-misses, and full compliance with stringent German Arbeitsschutzgesetz and Tesla site rules. Trusted as a recurring contractor for facility modification works.

PROJECT // 04 PARIS HUB (PAR) • FRANCE Tier III Multi-Tenant Cloud Hyperscale

SIKLA / HILTI CERTIFIED • FRENCH BTP COMPLIANT

Heavy Modular Secondary Steel Framing & Seismic Pipe Trapezes

Sikla SiFramo & Hilti Unistrut Load Rating: 4.5T / Bracket 300-Meter Corridor Spans Spring Vibration Isolators 100% EU Delegation Cleared

01. The Client Challenge

Supporting massive hydraulic loads of DN300 chilled water risers and heavy fire headers along 300-meter distribution corridors without compromising or penetrating post-tensioned structural concrete floor slabs.

02. Weldkar Assembly & Execution Scope

Weldkar mechanical fitters constructed modular secondary steel grids utilizing Sikla SiFramo and Hilti heavy channel systems. Teams assembled multi-tier trapeze supports, seismic anchor brackets, spring dampers, and precision pipe guides aligned to millimeter tolerances from 3D BIM coordinate models.

03. HSE Record & Handover Outcome

Structural load verification passed without deflection anomalies. All French administrative documentation (Carte BTP, URSSAF, A1 certificates) was handled 100% autonomously by Weldkar, removing all legal risk for the general contractor.

TURNKEY MEP • COMPLETED ON SCHEDULE

Turnkey HVAC, Central Heating & High-Bay Warehouse Sprinklers

DN250 Boiler Room Headers In-Rack ESFR Sprinkler Grid Hydronic Chilled Water Loop Automated Zone Valves Multi-Trade Coordination

01. The Client Challenge

A major corporate headquarters and automated e-commerce distribution center required complete mechanical piping installation with strict handover dates prior to seasonal winter heating commissioning. High ceiling bays required complex coordination with automated conveyor systems.

02. Weldkar Assembly & Execution Scope

Turnkey mechanical piping scope covering central boiler room headers, hydronic heating/cooling distribution loops, roof-level sprinkler mains, and in-rack early-suppression fast-response (ESFR) sprinkler networks. Weldkar handled all material logistics, welding, grooved jointing, and system balancing.

03. HSE Record & Handover Outcome

Delivered cleanly on schedule with full hydraulic pressure certification. All thermal loops and fire suppression systems passed contractor and municipal safety acceptance with zero warranty punch-list items.
