We undertake a wide range of surveying tasks such as asset condition, spatial, cable tracing, record correlation, buried services, utilities etc. We deploy staff with the right technical experience to identify each asset, its system, function and owner. See case studies

We undertake surveys of entire sections of the railway to understand the aggregate mass of infrastructure. Our surveying commissions are often combined with feasibility studies, construction impact assessments, costs benefit analysis, enabling works strategies etc.

Our strategy is always to minimise time on site. We plan and scope surveys thoroughly ensuring the information acquired is 'right first time'. We use the latest technologies such as laser positioning, GPS location, time/date stamping and digital photo-capture. We treat the survey methodology and final information outputs as one integrated process.

We view survey data as a valuable asset in its own right. How it is stored and made accessible for future users is always a key consideration. We frequently use BIM and other information management tools to manage survey data. In particular how new and existing data combines to form a 'single version of the truth' thus minimising future repeat surveys. See our BIM capability >

Wessex Capacity Enhancement - Waterloo Station & Outlying Areas

Wessex Capacity Enhancement - Waterloo Station & Outlying Areas image

Fourway partnered with Amey to develop a comprehensive picture of existing asset information to support the Capacity Enhancement Programme. Rather than the two organisations retaining their corporate identities to form a rigid, hierarchical relationship we created a single collaborative project organisation. Whilst the bid responsibilities
