This online engineering PDH course provides introductory information about special design considerations, equipment, materials and construction methods for mechanical and electrical utility systems, including water, wastewater, heating, power and communication utilities in arctic and subarctic regions. 

A utilidor is a conduit that contains multiple utility systems such as water, sewerage, fuel oil, gas, electrical power, telephone, and central heating in various combinations or in some cases all together.  They have been used at a number of installations and communities in the North American Arctic. 

Utilidors are very expensive and can only be justified for special situations.  In most cases individually insulated pipes in a common trench or on a common pile will be more economical.  Utilidors have been constructed above and below ground, and range in size from a simple insulated conduit to a walk-through passageway.  New designs typically incorporate lighter construction materials than the reinforced concrete used previously at many installations. 

This 1 PDH online course is intended for civil, environmental, mechanical and electrical engineers and other design and construction professionals wanting to learn about utility distribution systems, facilities and equipment in arctic and subarctic regions. 

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

Learning about pile supported and in-ground utilidors

Learning how hot water and steam lines in utilidors affect other utility lines and cables

Learning about cross-connection control when sewage lines are contained in utilidors

Learning how to provide an effective electrical grounding system in permafrost conditions

Learning how to design aerial power and communication cable towers in permafrost conditions

Once you complete your course review, you need to take a multiple-choice quiz consisting of twelve (12) questions to earn 1 PDH credit.  The quiz will be based on the entire document. 

The minimum passing score is 70%.  There is no time limit on the quiz, and you can take it multiple times until you pass at no additional cost.
