INTRODUCTION

This Erection Manual covers the recommended procedures for safe and efficienterection of International Building Systems Factory Co. Ltd. (IBSF) buildings.

However, IBSF does not guarantee and is not liable for the quality of erection of

its buildings. It is not the responsibility of IBSF where building defects occurdue to improper erection techniques, or the negligence of other parties.

The Manual includes procedures on claim for short shipment and replacement ofdamaged materials.

Part 4. ALTERATION OF MINOR ERRORS

All erection works will be treated as outlined in the American Institute of SteelConstruction Code of Standard Practices for Steel Buildings and Bridges (Section 7).

It deals with the correction of errors in situations where the material is not being

erected by the Fabricator and which reads in substance as follows:

"Corrections of minor misfits by the moderate use of

drift pins, and a moderate amount of reaming, chippingor cutting are considered a part of erection. Any error

which prevent the proper assembly of parts by these

measures, or which require correction or adjustment,must be reported immediately to the fabricator and

erector to enable whoever is responsible either tocorrect the error or to approve the most efficient and

economical method of correction to be used by others."

The Builder/Erector shall immediately report to IBSF whenever there are errors in

shop fabrication that prevent the proper assembly and fitting of parts by the use ofdrift pins, reaming, chipping or cutting. The report shall clearly describe the problemand a suggested solution will be most welcome.

IBSF, in turn shall analyze and correct the error or approve the method and cost oferection to be made. IBSF shall have the option of:

1. Replacing the defective material with freight allowed to jobsite by carrier of

IBSF's selection.

2. Authorizing field correction of the problem by a method and at a cost agreed

to by IBSF.

Where field correction is authorized, the Builder/Erector shall be allowedcredit for the agreed cost, but in no event shall IBSF be liable for

consequential damages.


38/58

Part 5. STORAGE AND PROTECTION OF COVERING

Upon receipt of the material, it is important to examine packages for damage.

Builders and/or Erectors are encouraged to take prompt action where cuts, tear or

other damage is evident. The sheets should be dried before restacking or storageshould it be noticed that a small amount of moisture is present. Damp sheets should

never be restacked until thoroughly dry.

A. Aluminium, Galvanized and Galvanized Prepainted Sheets

Aluminium, galvanized, or the galvanized prepainted coating on piled flat

sheets or nested formed sheets become wet from rain, natural condensation, or

other causes, white rust may result.

This may occur either or in storage at the jobsite.

B. Formed Prepainted Sheets

Formed pre-painted sheets must be protected from moisture in the same

manner as plain galvanized sheets until boldly exposed to the weather. The

sheets must be properly packed and stored. Otherwise, white rust may

develop at minute paint cracks and at the cut edges.

C. Roofing and Siding Sheets

These sheets should be erected as soon as received at site. However, if

temporary storage is absolutely necessary, they should be stored indoors.

Where indoor storage is not possible, the procedure shown in this Manual

must be followed to prevent entry of moisture into the bundle and consequent

storage stain.


39/58


40/58

Part 7. CLAIMS

The Owner, Builder or Erector should inspect all the materials that are being shipped

to the jobsite.

It is the responsibility of the Builder or Erector to report any shortage in shipment or

defective material immediately to the owner, or customer to enable him to file a claim

for the shortage or defective material.

Claims for shortages or defective material, if not packaged, must be made in writing

to IBSF within five (5) days after receipt of the shipment.

If packaged items are found to contain shortages or defective material, these must bereported in writing to IBSF within thirty (30) days after receipt of the shipment.

All claims must be reported in detail giving part numbers, description and length.

This information may be obtained directly from the Bill of Materials furnished with

the building.

See Appendix B for IBSF's claim policy. Please read these carefully and follow the

procedures outlined therein.
