1. Purpose
The purpose of this procedure is to lay down the method to define the scope, extent and type of thermal/acoustic insulation and coating work for "package units" and "machinery" and to obtain vendor's quantities and technical descriptions. This may be based on relevant specifications by Company, purchaser or vendor's standard finishing/installation systems, as included in vendor's order. The goal is to achieve a better work definition (including technical requirements) for the insulation and painting subcontractors.
2. General
This procedure shall be used on all projects, unless otherwise directed by the Client or Project Manager, i.e. usage for a limited number of package units and machinery or for insulation or for coating only.
3. Responsibilities
The Company Package Unit Engineer (or the Mechanical Engineer) preparing relevant requisition is responsible for:
- the application of this procedure
- the incorporation of text and forms in the requisition
- the evaluation of vendors' data.
The Company Insulation and Coating Engineer is responsible for:
- the evaluation of vendors' data
- the inclusion of relevant data in the subcontract package(s).
The Project Procurement Manager or his delegate is responsible for:
- the ensurance that the requisition packages are issued correctly and complete to bidders/vendors
- the circulation of bid documents to the relevant engineers for technical evaluation
- the expediting of vendors' activities.
4. Procedure
4.1 The Package Unit Engineer (or the Mechanical Engineer) shall incorporate the following information in the requisitions.
4.1.1 A paragraph with text as follows:
- the package unit, respectively machinery vendor shall complete and submit to Company, within the normal vendor print handling, the completely filled out quantification sheets for thermal/acoustic insulation and coating work, including attachments for technical data and manufacturer's names as applicable, at the earliest possible date after order placement. It is vendor's responsibility that his subcontractors also comply with this requirement.
Package units comprise i.e.:
- vessels, piping, structural steel, pumps, instrumentation, various machinery, etc.
Machinery comprises i.e.:
- the housing of rotating machinery (pumps, gear boxes, motors, mixers, agitators, etc.), electrical equipment, instruments, and their outdoor cabinets, level indicators, transmitters, etc. weigh bridges, scales, travelling cranes, hoisting tackles, loading arms and the like, including the auxiliaries connected to any of such items.
4.1.2 The quantification sheets (see attachments 1 and 2, RB24001 and RB24002) for the vendor to complete (under Document Classification Number - DCN).
4.2 The Project Procurement Manager issues the documents and/or reissues documents for correction to the vendors.
4.3 The vendor completes the quantification sheets and adds relevant information as indicated on the quantification sheets.
4.4 The Project Procurement Manager expedites the vendors and circulates data to Specialist Engineers within the normal vendor print handling.
4.5 On receipt of the vendors' completed quantification sheets via the procurement group, the following engineering activities shall take place:
- the Package Unit Engineer (or the Mechanical Engineer) reviews the filled out quantification sheets as to item description, quantity, type of skin material and temperature
- the Insulation and Coating Engineer reviews the technical aspects of insulation and coating.
4.6 When vendor has not completed the quantification sheets correctly, the sheets are returned to the Procurement Manager for reissue.
4.7 When vendor has completed the quantification sheets properly, these sheets are collected by the Insulation and Coating Engineer.
4.8 The completed quantification sheets are incorporated in subcontract package by the Insulation and Coating Engineer (ref. paragraph 6.2).
