Online Estimating Guide

Introduction

This updated second edition of the guide supersedes the first edition published in 1998. The estimating method is largely unchanged, though some of the elemental components used to build up the connection costs have been rationalised.

The purpose of this guide is to set out a method and provide sufficient data for design, fabrication and construction professionals to develop quick and reliable preliminary estimates of the constructed cost of structural steelwork for building projects in New Zealand .

The range of typical load rated connections used in the guide correspond to those published in the Structural Steelwork Connection Guide, SCNZ 14.2:2007. Other non-load rated connections and steelwork work items are also tabulated to allow rapid selection of connections for preliminary estimating purposes.

The estimator does not need to have a detailed technical understanding of structural steelwork design issues. However an appreciation of the work activities and the organisational aspects involved in the fabrication and erection of structural steelwork is important. This guide aims to assist the estimator with some key insights into the measurement of work processes and their appropriate pricing.

Connection data tables have been developed using a work process based method applied to a model workshop using typical work processes and equipment. The intention is to assist an estimator determine a reasonable industry budget price and provide the basis for intelligent commercial negotiation. Section properties useful for estimating are included as are supply and fire rating rates.

The data presented is used by Steel Construction New Zealand in preparing preliminary estimates for steelwork options for construction project teams. Feedback from project teams, quantity surveyors and fabricators has been used to help ensure that the estimates developed reflect current market expectations. For more project specific pricing information users are recommended to contact their local steel fabricators and materials suppliers.

All prices quoted are exclusive of GST unless stated otherwise.

Steel Construction New Zealand wishes to record its appreciation of the many individuals and organisations in New Zealand and Australia who provided data and assisted in the development of this edition. Particular credit is due to Steel Construction New Zealand staff, Kevin Cowie, Jignesh Bhatt, Xiao Huantian in the development and review of the On-line Estimating Guide.
