TD&H started the Lewiston office in 1994. Over the last 21 years, we have grown from four people to a full-time professional staff of 16, including three registered professional engineers, a certified grant administrator, professional geologist, registered land surveyor and dedicated support staff.
Historically, the Lewiston office has been very strong in transportation work, designing miles of roadways, highways and bridges for the Idaho Transportation Department and cities and counties within both Washington and Montana. Surveying has also been part of the backbone of our operation, and our full-time survey crew are experts in all types of boundary, topographic and construction surveying.
In July of 2012, TD&H merged with Progressive Engineering Group. We are excited to now offer expertise in water and wastewater system design. In addition, we are now the only regional engineering firm that offers both top-notch design services and certified grant administration.
Our local construction division provides in-house expertise in heavy construction as well as materials and compaction testing.
