Alan H Reid Pty Ltd
- Australia
Marketing Manager

1985- Managing Director


Grew a small agency based company from less than $500K turnover

to a strong, profitable business of sales exceeding $30million and operations throughout Australia, New Zealand and Singapore

by introducing six ground-breaking engineering technologies (now considered standard practice) in Australia and New Zealand:

Engineering Construction

Concrete Lifting Systems

engineered systems for safe lifting of precast concrete panels and products

Swiftlift precast systems designed, developed and manufactured with partners DEHA (Germany) and ARTEON (France). Patents for improved for Edge lifting anchors. Tilt-up systems and design program

Structural Expansion Anchors

rational limit state design method based on "proof slip": 0.1mm slip
Developed the Proof Slip design method adopted by Australian Standards AS3850 and Tilt-up codes. Introduced Liebig Anchor & Safety Bolt

Stud Shear Reinforcing

efficient shear reinforcement in thin slabs around columns, pile caps and seismic designs

Funded research by Dr BV Rangan to develop a design method for AS3600. Invented the double-headed Studrail, first used in offshore concrete platform "Bream B", now used internationally

Concrete sandwich-panels

technology and construction systems

Applied CSIRO thermal modelling to develop comfortable concrete design

Threaded Reinforcing

for standard grade reinforcing bars

Devised Reidbar reinforcing solutions to everyday construction problems


Mining Engineering

Compact Strand steel wire ropes

for open cast and deep level mining

Significantly boosted performance and productivity through rope life improvements of 50%+ in many mining applications.

Member of Australian Standards committees for Steel Wire Rope & Strand, Concrete Reinforcing Materials, Concrete Prestressing Strands, Powder Actuated Fastenings, Tilt-Up & Precast Concrete

Note: Alan H Reid Pty Ltd and Reid Engineering Systems (NZ) were sold in 1997 to National Consolidated Ltd (NCL) and the steel wire rope business to Haggie Ltd

Business and Materials Consulting


A welcome change of direction for 5 years! 2003...took up cycling!

Developed a superior, quick release Tilt-Up lifting claw ("clutch")

Concrete anchorage design consulting


2006 -

Hillside Engineering Pty Ltd

Director and Principal Consultant


Design, research and development of the EdjPro system - an improved system for edge lifting thin concrete panels comprising "EdjPro hairpin" lifting anchors, recess former system and a new EdjPro lifting clutch. EdJpro systems eliminate edge cracking problems speed erection and reduce the cost of thin concrete panels.

Design, research and development of a new Locking Klaw, and improved lifting clutch for safer, faster and more economical lifting of spherical head "Haeussler patent" lifting anchors.

EdjPro and Locking Klaw lifting systems are available from our licensee Unicon Systems in Australia and New Zealand where they are exclusively distributed by Cookes in NZ.

The Unicon companies were established to manufacture and market our systems.
Rod Mackay-Sim is the Technical Director of both Austaliand and New Zealand companies

Continuing research for the development of a rational design method for anchorage capacities of anchors in the edges of thin concrete panels with a paper presented at the Cement and Concete Institute of Australia Conference, "Concrete09" discussing a new design method for Edgelifting of thin Concrete panels.

And...Lots of Cycling for charity...
