INTRODUCTION

This Erection Manual covers the recommended procedures for safe and efficient
erection 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 occur
due to improper erection techniques, or the negligence of other parties.
The Manual includes procedures on claim for short shipment and replacement of
damaged materials.

Part 1.

ERECTION

The Builder/Erector is responsibile in mobilizing, receiving, off-loading and
providing the necessary tools for the proper erection of an IBSF building.
Before raising the next component, the structure should be adequately braced at all
times. It must be secured with temporary or permanent bracing before releasing the
raising equipment. Moreso, it is important to provide these bracings at the end of the
day, during week-ends or during shut downs.
During the start of the erection, the first braced bay must be erected with all the wind
bracing, eave struts, purlins, girts and flange braces installed completely. All bolts
must be properly tightened to make certain the building is properly braced (see
appropriate pages that follow in this manual).
All joints should be made up of all bolts in place before releasing the raising
equipment.
Sheeters should have something to stand on. Until the first run of roof sheets is
secured, temporary scaffold should be used to start sheeting. See proper method of
walking on the roof described in the sheeting section of the manual.
Any uncovered opening on the roof should be properly guarded. All sheeters should
be cautioned regarding roof openings.
It is important for workers not to slide down the columns and other structural
members. Ladders should be used to get on and off the building. Wall girts and
diagonal braces should not be used as ladders.

Part 3.

RECOM M ENDED TOOLS AND EQUIPM ENTS FOR
ERECTION

Listed below are the tools and equipments considered to be adequate for erection of most
IBSF buildings. However, actual equipment requirement depends on the type and size of
the building, job site conditions, and erection personnel. This list serves as a
recommendation and should not be used as a basis for inventory of erection equipment.
Use and maintenance of power equipment should be in accordance with the general
guidelines set forth in this manual.

ALTERATION OF MINOR ERRORS

All erection works will be treated as outlined in the American Institute of Steel
Construction 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, chipping
or 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 to
correct 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 of
drift pins, reaming, chipping or cutting. The report shall clearly describe the problem
and a suggested solution will be most welcome.
IBSF, in turn shall analyze and correct the error or approve the method and cost of
erection 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 allowed
credit for the agreed cost, but in no event shall IBSF be liable for
consequential damages.

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 storage
should 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.

Part 6.

INSPECTION BY IBSF

IBSF shall have the right to inspect all erection works being carried on by the Builder
or by others. It shall be the Builder's/Erector's responsibility to furnish permits, if
required, for entry to the jobsite for the inspection. All the necessary equipment
required (ladders, levels, etc.) for the inspection shall likewise be provided by the
Builder/Inspector. If requested, Builder/Erector will receive a copy of the Inspection
Report.
In the event, erection errors are detected at the time of inspection, the Builder/Erector
will be notified of the errors in writing with a suggested solution or method of
correction. Should these errors are not corrected by the Builder/Erector, IBSF will
notify the owner in writing along with a copy of the report. The Builder/Erector will
be furnished a copy of the notification to the owner.
IBSF shall have no liability to the Builder/Erector or to any customer for defective
workmanship in the erection of the buildings including by way of description, but not
by way of limitations, defects arising from loose connections, missing parts, roof
leaks, damaged sheets, omission of sealer, or closures, scratched surfaces, poor
alignment, inadequate drainage or defects arising out of materials furnished and/or
installed by Builder/Erector or others.
The Builder/Erector agrees to indemnify and hold harmless from any and all claims
which may or might be made against IBSF by any customer or owner arising from or
growing out of defects in the erection of any IBSF buildings erected by or under the
direction of, or for the account of the Builder and/or Erector.

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 be
reported 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.

side of head to end to bolt axis
axis and other sloped not more than 1 : 20
of bolt)
more than 1 : 20 from normal to the
(beveled washer not bolt axis (beveled
