Purchasing decides whether the chiller shows up before the crane is booked and whether the pipe is on site when the crew is. Here is how purchasing teams are built at mechanical contractors and what they need to know.
Enters POs, sends releases, tracks confirmations and delivery dates, and keeps submittal and order status current for PMs and the field.
Owns buying for a group of jobs or a commodity such as pipe, valves and fittings, sheet metal or equipment. Gets quotes, compares scope and negotiates terms.
Runs the purchasing team and the project buyout process. Sets vendor terms, manages escalation and tracks long-lead equipment across all jobs.
Sets supply chain strategy for the company: national agreements, preferred vendors, volume pricing, credit terms, warehouse and prefab supply, and risk on major equipment.
Build chillers, AHUs, RTUs, VRF, boilers, pumps and controls. Purchasing must know who makes what and how factory lead times move.
Sell and support engineered equipment in a territory. They quote, run submittals, track factory orders and coordinate startup.
Stock and resell equipment and parts from many brands, often with branches, counter sales and credit lines.
Plumbing, pipe, valves, fittings, hangers and fire supply houses that supply the daily material for construction and service.
Sheet metal and duct, insulation, rental equipment, cranes and rigging, testing services and freight carriers.
Chillers, cooling towers, AHUs, RTUs, boilers and switchgear-dependent equipment often carry the longest factory lead times.
Steel, copper, PVC, cast iron and press fittings. Prices move with commodity markets, so quotes have short hold times.
Fixtures, water heaters, backflow devices and drainage products.
Shop-fabricated or bought-out duct, fittings, dampers and accessories.
Pumps, control valves, expansion tanks and hydronic specialties.
Controllers, sensors, actuators and network devices, usually tied to the controls subcontract.
Track submittal approval, release, production and ship dates for every long-lead item, and flag slips early to the PM.
Arrange freight, special permits for oversized loads, and confirm ship dates with the factory or rep.
Coordinate delivery windows with the site, crane picks and laydown space. Check for damage before signing.
Use the warehouse or prefab shop to hold and kit material until the crew needs it.
Handle restocking, partial shipments and substitutions without losing the schedule.
