We are pleased to provide this letter of reference for Mark McFarlane and GoldWing Construction (GoldWing) in the area of interior construction.

GoldWing has been our go-to contractor in the area of interior construction for more than 10 years and we have worked with Mark McFarlane for more than 25 years.

GoldWing provides all of our renovation needs for our Edmonton office, which is approximately 60,000 sqft. The project size that they have undertaken for us has ranged between less than $5,000 and in excess of $800,000.

Most recently GoldWing completed a top to bottom renovation of our Edmonton building over a six-month period. They handled all the logistics, which included doing the renovation in a working office of 240 people. Their staff and trades worked respectfully and effectively with our employees to complete the work with minimum disruption to our business.

Our company philosophy is to develop strong relationships with our service providers and vendors such that some of them become our trusted associates. GoldWing is one of those trusted associates.

Yours truly,

Tetra Tech Canada Inc.
