Engineering drawings and project plans
iAppStack · ProcEng

Source globally.
Engineer precisely.

Procurement and engineering under one roof — vendor networks, RFQs, CAD, and project delivery for plants, OEMs, and infrastructure.

Two pillars

Procurement + Engineering
as one delivery team

Buyers get qualified suppliers and landed cost. Engineers get drawings that can actually be built. You get one accountable partner.

Why ProcEng

Drawings, vendors, and schedules that actually line up

Too many projects stall between engineering intent and purchased reality. We close that gap: specifications written for the market, suppliers scored for capability, and packages issued so fabrication can start on time.

  • ✓ Dual-discipline team — buyers and engineers in the same review
  • ✓ Multi-source RFQs with comparable technical bids
  • ✓ ISO-minded documentation and inspection hold points
