Trade terminology and component identification: methods and worked application

A naming method from place to order line, who supplies each part, the installation order of a cleat-and-cover edge from one maker's guide, and worked examples for girth, hems and piece counts.

You will be able to: Apply a written method to name every part of an assembly and say who supplies it, follow the order one maker's cleat-and-cover edge is installed in, and work through a drip edge, a hem and a run of pieces with every number sourced.

A naming method

Name a part in the same order every time: where it sits, the assembly, each part outside in, who supplies it, then material, legs and hems, and a read-back.

The flow chart shows each move, with a decision at who supplies the part and at any word with two meanings.

From a place on the building to an order line the shop can makeFlow chart: locate the part on the building, name the assembly, list the parts outside in, give each its trade name and AFS name, decide who supplies each part, record material, unit, finish and colour, record legs, hems, side, girth and length, stop at any word that means two things and write it out or ask, read the order back against the drawing, then send it.Where on the building?edge, parapet, wall, drainName the assemblyList the partsoutside inEach part: trade nameand AFS nameWho supplieseach part?AFS metalBy installer:membrane,strip, sealantMaterial, unit,finish, colour nameLegs, hems, side,girth, lengthAny word withtwo meanings?yesnoWrite it out,or ask inan RFIRead it back againstthe drawingSend the order

Flow chart: locate the part on the building, name the assembly, list the parts outside in, give each its trade name and AFS name, decide who supplies each part, record material, unit, finish and colour, record legs, hems, side, girth and length, stop at any word that means two things and write it out or ask, read the order back against the drawing, then send it.

The method in one flow. The two diamonds are the decisions: who supplies the part, and whether any word means two things.
