Q&A with Sally Doyle, Senior Engineer

When did you join us?

I joined in June 2021.

Tell us more about your career journey with us

During my short time with CGL so far, I’ve been involved in a number of interesting projects, including site works across the country investigating sites for residential and commercial developments, ground subsidence, geomorphological assessments, geotechnical design projects. All have been great to be involved with. Personal favourites include having eight piglets keep me company while logging some chalk core in a field in Oxfordshire and sitting out on the beach with an ice cream while waiting for high tide to take a water sample from an estuary in Brighton.

What does a typical day look like for you?

It varies so much; it could be a day in the office, a half day out doing a walkover or some ground gas or groundwater monitoring, or a few days on site in the mud. No two days are ever the same!

What do you like about our culture and working with us?

The culture is great; there’s no “big scary boss” you need an appointment to speak with; we’re a good team of friendly people which makes for a lovely working environment in the office. Colleagues are always on hand to help and support you when necessary.

How has CGL supported your career growth?

CGL has allowed me to expand my knowledge and skill set over many areas of geotechnical and geoenvironmental engineering by involving me in a huge range of projects which has allowed me to evaluate where my interests lie and what to pursue further. CGL has been extremely supportive and encouraging to undertake projects that allow me to focus on areas I’m keen to develop further.

What tips would you give new graduates entering the engineering/construction industry?

Starting out in the industry is a steep learning curve; it’s very different from university. It’s ok not to know how to do something; it’s ok to ask questions and ask for help. We all have been there. Don’t pass up an opportunity to learn something new or expand your knowledge and practical skills in the field.
