Field Guide / Bid Desk
What an EPC or mine owner needs to send an equipment supplier to get a real quote back in a day — not a caveated placeholder two weeks later.
Most RFQ packages sent to equipment suppliers describe the pipe size and the flow rate and stop there — leaving out the two variables (exact concentration and confirmed operating temperature) that actually determine whether the quoted material survives in service. A material rated fine for 75% H₂SO₄ can crack at 98.3% from a sulfur trioxide contaminant that only appears above that threshold.
Not every mining equipment category has a dedicated CSI MasterFormat section. Slurry pumps fall under the general Centrifugal Liquid Pumps category — there's no separate "slurry pump" code. Heap leach irrigation systems have no dedicated CSI section at all. A bid package that assumes one exists can send both sides chasing a number that was never real.
The single biggest cause of a bid invitation stalling isn't the equipment quote — it's vendor registration paperwork arriving late or piecemeal. Mining procurement is largely private and EPC-led, not run through public plan-holder lists, which makes sending onboarding requirements up front even more important than on a municipal bid.
This guide reflects LibertyCES's own bid-desk experience as of September 2026. Individual project and agency requirements vary — confirm the specific documentation your process needs directly.
Six categories of real process data: the leach chemistry and guaranteed concentration range, temperature and flow conditions at each stage, the exact CSI spec section if one exists, the manufacturer basis-of-design, vendor onboarding requirements sent with the invitation, and the bid timeline.
Commercial "98%" sulfuric acid can run above 98.3% on the certificate of analysis — a materially different design condition that determines whether the quoted material actually survives in service. A supplier quoting from the chemical name alone, without the guaranteed range, is quoting blind.
No. Slurry pumps and mining pumps fall under the general Overhung Horizontal Centrifugal Pumps category (Section 43 23 13) — there is no separate slurry pump code. Heap leach irrigation systems have no dedicated CSI MasterFormat section at all. A bid package that assumes one exists can send both sides chasing a number that was never real.
