Project overview

Complex projects. clear communications

WSP is a global engineering consultancy delivering major infrastructure projects across the UK. Many of those projects need statutory or engagement communications to residents and businesses inside evolving project boundaries, with materials that have to reach the right addresses at the right time, backed by verifiable evidence of delivery.

We support WSP with Engage for mapping and planning, multi-channel materials for different campaign types, and +POST tracked delivery where guaranteed dates and GPS verification are required.

The challenge

Changing boundaries. guaranteed timelines

Infrastructure project boundaries evolve as designs develop and programmes progress. WSP needed a platform that could update delivery zones quickly, combined with a distribution service able to guarantee delivery dates and provide audit evidence for statutory engagement.

Evolving project areas

Boundaries change as infrastructure designs develop, so mapping had to update quickly without reprinting and replanning from scratch.

Guaranteed delivery

Statutory consultation windows are fixed, so guaranteed delivery dates replaced the uncertainty of standard postal distribution.

Stronger evidence

GPS-tracked, time-stamped delivery confirmation provided stronger evidence than estimated postal timings.

Our approach

Engage. track. evidence

We support WSP with Engage for flexible zone planning, appropriate channel selection for each campaign type, and +POST tracked distribution where guaranteed delivery and GPS evidence are required.

01

Engage mapping

Flexible zone planning updated as project boundaries evolve across each programme.

02

Multi-channel materials

Letters, leaflets and other campaign materials produced and packed for each deployment.

03

+POST delivery

GPS-tracked distribution with guaranteed delivery dates and time-stamped evidence per address.

04

Audit evidence

Full GPS delivery records provided to support statutory consultation and engagement reporting.

The impact
100%
GPS-verified delivery on +POST campaigns across WSP projects

WSP's communications teams have moved from estimated postal timings to guaranteed, GPS-verified confirmation, which gives them stronger evidence for consultation records and more confidence across complex, evolving infrastructure programmes.

"
Moving to +POST made a real difference. We have guaranteed delivery dates and GPS evidence we can use directly in our consultation records, and Engage lets us update our zones quickly as project boundaries change.
