Up front capital invested can range from as low as $500 for a small, shallow pond aeration system to as much as $8,000 or more for a larger system or a solar aerator.Operating cost is dependent on the number of amps needed to power an electric motor multiplied by the electricity cost in your area.ome electric aerators might run for 2-3 years without any major issues and others might run 5-7 years or longer. The table below is based on a set of assumptions that is fairly representative of actual costs for a 1 to 2 acre pond or small lake.
Surface Hub costs less than half that, and is in essence a collaborative center in a box. Costs for a conference room that would accommodate the lower-end unit are about $6,500 to $27,000, again not including furniture, installation, service, and ongoing management costs, so a similar savings can be had there as well.
Most of these headaches can be avoided with better and more complete information presented early in the project. Here are some basic Tenant Improvement cost guidelines for typical space, including costs to design, permit and construct the improvements: 1  Carpet and paint for an existing unoccupied space: $5 â $7/sf.2  Carpet and paint for an existing occupied space: $8 â $10/sf. Major remodel of an existing space: $35 â $50/sf. 2  New construction on a warm shell space (restrooms/lobbies already built): $50 â $65/sf. 3  New construction on a cold shell space (no restrooms or lobby yet): $60 â $75/sf.
