The W.D.M. Limited consultancy service was developed to help clients maximise the use of survey data and has a unique understanding of highway maintenance management and infrastructure asset management.

The Consultancy team is led by Chartered Civil Engineers, working within an ISO 9001:2008 third party accredited quality system and provides specialist assistance and support to central and local government and the private sector to manage and maintain their highway and road assets.

The specialist advice available is ideal for clients who can no longer justify in-house expertise in all areas to deliver effective services.

The Consultancy team is experienced in producing cost effective solutions and expertise covering infrastructure asset management; road condition assessment, particularly relating to skidding resistance policies; financial modelling and long term road and highway maintenance programmes. The team also supports knowledge transfer, providing training based on both national and international experience. 

Analysis and Reporting

The WDM® Consultancy team has a long established reputation for clear understanding of structural deterioration of flexible pavements and road condition surveying and can provide detailed analysis of condition data, or undertake one off projects using condition data.


Asset Management

WDM® has worked for many years in Australia and New Zealand, giving the Consultancy team invaluable insight into the experience gained by those countries, which is now generally accepted as setting the benchmark for highway and road condition assessment and monitoring.



Effective infrastructure asset management relies on accurate and up-to-date network referencing. With the introduction of the Localism Bill in the UK, and the Department for Transport’s move from the use of road class to road hierarchy, it is appropriate to audit the current network and review to determine if it remains fit-for-purpose in the current economic climate.


Scheme Identification and Prioritisation

Implementing an effective Highway Asset Management Strategy relies upon robust systems for scheme identification and assessment. Increasingly highway authorities need to demonstrate that they are achieving value for money from the schemes that they carry out.


Skid Resistance Strategy

The WDM® Consultancy team has extensive experience of implementing skid policies, tailored to the needs and resources available, to a range of highway networks, from small authorities and private ventures through to central government organisations.



WDM® staff provide training courses covering all aspects of the Company’s work as well as supporting national conferences. The Company has also taken a leading role in organising and running International Conferences with the theme of Safer Roads.
