Three ways to describe what you need.

By Drawing

You already have a dimensioned drawing.

What to provide

• Dimensioned drawing or CAD file exported to PDF, plus source format if available
• Revision number, units and any applicable tolerances
• Operating and maximum temperature, working medium and indoor/outdoor environment
• Required access to handwheels, actuators, nameplates or inspection points

What TERCC does

• Read the drawing against the equipment description
• Log open questions rather than filling gaps with assumptions
• Return a consolidated specification for written approval

Outcome: A reviewable specification before any supplier commitment.

By Equipment Photos & Measurements

No drawing exists yet.

What to provide

• Clear photos from at least two angles, with a scale reference in frame
• Key dimensions with units, including clearances around the equipment
• Equipment type, connection type and any adjacent obstructions
• Whether the item can be taken out of service for measurement

What TERCC does

• Build a measurement checklist for the specific item
• Clarify missing dimensions in writing
• Prepare a drawing for your approval once the geometry is understood

Outcome: A buyer-approved drawing derived from field information.

By Reference Design

Start from a structure, then adapt it.

What to provide

• One or more TERCC-RD reference codes from the gallery
• Which structural features must be kept and which may change
• Item quantities and any tagging convention
• Any site-specific constraints

What TERCC does

• Treat the reference code strictly as a concept structure
• Record each deviation from the reference in the specification
• Confirm that no reference implies stock or validated performance

Outcome: A single RFQ covering several adapted reference structures.
