3.3 CUTTING To NZS 3404.1, and for existing steel HERA R4-99. Hand cut only where machine

cutting is not possible. 3.4 CONSTRUCT Construct the steel structure as detailed and to NZS 34041.1, section14, Fabrication and

section 15, Erection. 3.5 WELDING Carry out welding in accordance with AS/NZS 1554.1 and the additional requirements of

NZS 3404.1. Equipment to comply with AS/NZS 1554.1, clause 1.8.2. 3.6 WELDING NEAR TOUCHING STEELWORK Shop weld together touching or near-touching steelwork all round with 5mm (one pass)

continuous fillet welds unless denoted otherwise on the drawings. 3.7 WELDING GALVANIZED OR THERMAL SPRAYED STEEL When welding already Galvanized steel or Thermal Sprayed steel either: - remove coating locally and carry out a standard weld - leave coating and adjust welding technique to those recommended in GANZ After-

Fabrication Hot Dip Galvanizing document. (Among other things, this will generally mean a slower welding speed.)

Final weld shall meet all the standards and requirements of a standard weld. 3.8 HOLING Comply with NZS 3404.1 for sizes, alignment, finishing, punching and flame cutting of

holes. 3.9 BOLTING Bolting, including high strength bolting to NZS 3404.1. Ensure that at least one clear

thread shows above the nut and at least one thread run out is clear beneath the thread after tightening.

3.10 THREADS EXCLUDED FROM SHEAR PLANE Select length of bolts such that the threaded portion does not occur within the shear

plane between joined parts. 3.11 START ERECTION Start erection only when the holding down bolts and anchorages have achieved sufficient

strength. Carry out the erection of the structural steel to the requirements of AS 3828. Comply with NZBC F5 and NZS 3404.1, section 15, Erection. Provide temporary bracing as required to achieve stability during erection.

3.12 BASE PLATES Enlargement or site cutting of holes not permitted. Bending or displacement of holding

down bolts not permitted. 3.13 COLUMNS Plumb columns using sawn steel packs and wedges not larger than necessary for the

purpose. The column base must not be raised by more than 25mm. Fill space beneath

TENDER ISSUE














the base plate with cement-sand grout, containing a non-shrink additive, the grout having a minimum compressive strength of 30MPa at 28 days. Alternately use a dry pack of 1:2 cement with the sand mortar hammered in tight to ensure complete filling of space.

3.14 INSPECTION Inspect all stages of fabrication and construction of the structure to NZS 3404.1, sections

14, Fabrication and 15 Erection. 3.15 ENCASED STEELWORK Clean the steelwork to be encased in concrete to remove all loose mill scale, rust, dirt and

other matter affecting bond with concrete. Achieve this by wire brushing and the use of suitable solvents.

3.16 BRUSHING AND POWER TOOL CLEANING Remove oil and grease by the use of solvents. Scrape and power wire brush to a

minimum Class 2 finish to AS 1627.9. Clean to bright metal, but avoid producing a polished surface. Check that no burrs or sharp arrises remain which may prevent the full coating thickness being attained.

3.17 ABRASIVE BLASTING Remove oil and grease by the use of solvents. Abrasive blast clean to a Class 2.5 finish

to AS 1627.4. Clean to bright metal, but avoid producing a polished surface. Select grit type and equipment such that the cleaned surface profile between peaks and valleys does not exceed one third of the dry film thickness. Check that no burrs or sharp arrises remain which may prevent the full coating thickness being attained.

3.18 STEELWORK BEING GALVANIZED Fabricator to provide any temporary members required by the galvanizer to strengthen

prefabricated elements likely to be distorted by the subsequent hot dip galvanizing process.

To galvanize, clean sections thoroughly and apply zinc coating by the hot-dip process to the requirements of AS/NZS 4680. Average zinc coating to be not less than the following:

Structural steelwork Average coating Minimum coating

≤ 1.5mm 45 microns 35 microns

> 1.5mm ≤ 3mm 55 microns 45 microns

> 3mm ≤ 6mm 70 microns 55 microns

> 6mm 85 microns 70 microns

3.19 REPAIR WELD DAMAGED GALVANIZING Remove welding slag, power tool clean, grind off all burrs and sharp arrises, all repairs to

AS/NZS 4680, 8.4 Site repair: - Small repairs:- Colour matched zinc rich paint. - Large repairs:- With approval, colour matched zinc rich paint or other agreed option.
