I am the CAD Manger of the Rocky Mountain Business Unit of MWH. I have had the honor to work with Zoe Grant of ZGL Engineering Services, Inc. for the past year. She has worked with MWH since 2008. Zoe has proven her and her company to be of great character and spirit. She has developed strong relationships with our engineers, and earned their confidence in her expertise.

We have used ZGL for many projects, those which include mining, reclamations, dam projects and pipelines. She was the CAD Lead for the Panama Canal, Third Set of Locks Project- Pacific Locks Complex. She led the effort in the excavation, foundation, grouting, geologies, geotechnical instrumentation and embankment fill construction documents. She also completed all the grading for the site using Civil3D.

She is efficient and produces high quality work. ZGL gives every effort possible for projects to be done on time and on budget. ZGL's passion and work ethic cannot be matched.

I am confident that ZGL will have the same impact on you as she has had on us here at MWH.

We are well aware of the fine service that Zoe Grant Lewis provides from her previous contributions to the Stapleton Redevelopment Project as an employee of URS (recently acquired by AECOM). Zoe supervised our CADD group for land development and was instrumental in establishing strong CADD standards and managing the Buzzsaw collaborative website and its many users for the Stapleton project.
