Cliff and Lee
the story so far…

Cliff and Lee

Cliff and Lee first met while working at separate ends of the vast design facility at BCP Caterpillar way back in 2002. At that point in time Lee had just stepped foot into the world of Design Consultancy and Cliff was in full time employment as a Design Engineer.

During the time spent at Caterpillar while Cliff and Lee worked on different products and in different areas of design increasingly they found themselves using each other as a sounding board for design ideas and product improvements. Looking back at those early days it was clear then that the basic ingredients and ethos that make CAL the Business it is today was apparent then.

While Caterpillar was a great opportunity for both Cliff and Lee it was a long way from their homes in the North West of England so the journey home had to start somewhere.

Working their way up the Country they completed successful projects with Blue Chip OEMs such as Perkins Engines, and Rolls Royce Defence.

Time rolls forward and while working on a number of projects for Scott Safety (at the time a Tyco Company) the size and the scale of the CAL opportunity was too obvious to ignore. Dedicating all of the time and resource to one client was proving a challenge, and additional business opportunities were being missed.. It was at that point that CAL took the bold decision to move from the in business contract consultancy approach to a multi-business offsite consultancy.

What CAL is now is a direct result of all of the experiences of the past.
Cliff and Lee were determined to create a collaborative environment were all of the team feel part of the journey. The aim has always and will always be to offer the clients a complete Engineering solution, and to add as much value as possible to any project or product engaged with. Very simply to be seen as a partnership by CAL’s clients rather than additional resource.

May of 2018 will mark 3 years since Cliff and Lee took the decision to move outside of the conventional.. While in those early months of tireless hours of conversation bringing the new CAL concept to clients were not the easiest.. They were absolutely worth it now as we look in the rear view mirror at the thriving boutique Engineering Consultancy with a FIRST CLASS team of people here at CAL who make a difference to our company and Our clients.
