Allgeier, Martin and Associates, Inc. has a long history of substation design including new substations, additions, and upgrades for transmission, distribution and generation applications. Our design voltages range from 2400 V to 500 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. Additionally we are now also utilizing AutoCAD Inventor for 3-D design to assist in substation development.
We regularly 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 lower equipment costs and overall net savings to the owner. Designing of steel structures, and detailing newly modified structures in house which reduces the cost of steel by 10 - 20%. We internally design relay panels and point-to-point wiring, which maintains control, directly incorporating the client's desires, thereby reducing the final price. For many clients we prepare contracts and administer bidding, then award and the contracts.
We prepare detailed construction specifications including particular restraints and desires. Due to comprehensive preparation, our plans, specifications and material lists require minimal field modification or "field design." This is to the contractor's advantage thereby lowering the overall project expenditure.
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 provide a detailed checkout of the substation and assist with energizing and initial operation as needed.
