Best Practice EOI Guide

Best Practice EOI Guide


To assist you in the preparation of your expressions of interest we’ve put together some helpful tips on how to format quotations and expressions of interest for builders – with guidance provided directly by many of the best estimators across Australia.

Expression of Interest Basics


When expressing interest to a builder, it helps to follow a few simple guidelines to allow the builder to understand the scope of the services you provide.

Things you need to include:
  • Full contact details for the business and the most appropriate person to get in touch with (typically the estimator),
  • Previously completed projects, preferably of a similar nature to the projects you’re expressing interest for, 
  • The value of previously completed projects (your subcontract value, not the overall value of the project), name and details of the clients, 
  • Any appropriate references and their details, 
  • Whether you’re Nationally Code Compliant or have an EBA, 
  • What trade(s) you specialise in or service(s) you provide, 
  • How long you’ve been in business for and how many employees you have. 
Keep your EOI’s concise and to the point. Extra fluff isn’t necessary for these documents as a builder is only looking for a few key pieces of information. Primarily it’s about substantiating your track record. Help a builder see why they should do business with you, by demonstrating that builders have done business with you before. 

General Tips from the Estimators


Below are some tips from the estimators we surveyed that may assist you in preparing quotations and general estimating.
  • Be prepared to put in some hard work up front if you’ve not worked with a builder before – many subcontractors claim to be interested in pricing projects, only for them to not return a price once sent a set of documentation,
  • Understand that the builder will need a few days to vet the quotes that are received, so try and be timely with your submission and not leave it until the very last minute,
  • Big glossy brochures full of photos and marketing jargon are usually a waste of time, especially when included with tender submissions. It’s not necessary and a builder really cares about your track record, not how amazing your marketing department is. Generally speaking, a builder can simply check out your website if they want to see more information – so make sure you have a decent one of those!
  • Don’t pretend to be an Estimator's long-lost friend when you’ve never dealt with them before! Be honest and upfront about your enquiry – keep it simple and to the point.
  • Make sure you get the contact details for the person you’re dealing with correct (i.e. the estimator’s name!) as it indicates attention to detail, which is an important skill in the estimating profession.
