Substations

Allgeier Martin has a long history of substation design including new substations, additions, and upgrades for transmission, distribution and generation applications. Our designs have included all standard voltages from 2400 V to 500 kV with the majority being 69 kV-15 kV and 161 kV-69 kV. Bus configurations include simple tapped bus, transfer bus, breaker and half schemes and ring bus. We have designed substations with cable bus, angle bus and tubing bus materials. More frequently, space constraints and native topology require innovative and original designs. We are familiar with these challenges and have designed solutions for a variety of situations and constraints.

We can prepare material and equipment specifications for steel, transformers, breakers, switches, relaying and other items needed for the substation construction. Typically we retain design control by detailing these items more than other firms. This style often results in higher engineering costs but lower equipment costs - resulting in an overall net savings to the owner. As an example, we often reutilize existing designs of steel structures and detail new modified structures in house, which reduces the cost of steel by 10 - 20%. We design the relay panel layouts and point-to-point wiring, which maintains control, allows the client's desires to be included and reduces the final price. If desired, we can also prepare contracts and administer bidding, award and execution.

We prepare detailed construction specifications including particular restraints and desires. Due to this detailed preparation, our plans, specifications and material lists require little or no field questions or "field design". We feel this is to the contractor's advantage and his price can be lower since there is no design to be done. We can prepare contracts and administer bidding, award and execution for construction specifications as well.

We have experienced Site Representatives available to monitor construction progress and quality. They are also beneficial to answer questions in the field and serve as an interface between the contractor and owner-engineer.

Once construction is complete, we can provide a detailed checkout of the substation and assist with energizing and initial operation as needed.
