have typically been $30,000 or less, per year, however expenditures will vary depending on the

amount of work performed. The City will not guarantee a set contract value for these services.

design or construction that may require material testing or special inspection. Currently, the City

does not employ staff certified to perform these specialized services. The City requires the services

of qualified and experienced firms to assist in this type of work.

Firms should expect to perform a variety of material testing and special inspections on an “as

needed” basis. Services to be performed may include, but are not limited to, inspecting, sampling

CONSULTANT SELECTION PROCESS

services contract for the work after staff has determined the best qualified firms.

after a “short list” has been determined.
