Company

PHM has been supplying Engineering Design solutions since its inception in 1996. Two technologists, Steven Pearse and John Heddon founded the firm after they identified a particular niche in the Engineer industry, which needed to be addressed. This niche has been born from the advancement in computer technology, particularly the huge growth of the internet and the ability to transfer data quickly and securely, which has led to the creation of the Virtual Office. Further changes have been identified with the attitude of Engineering Consultants towards the outsourcing of certain design functions and with this in mind PHM has combined the above aspects to offer a professional and economical design solution to consultants who wish to take advantage of this modern technology and who require a more affordable and complete design facility, incorporating all the relevant technical fields in township development, of civil, structural and elecrical engineering, town-planning, ground rehabilitation, surveying and project management.
