If we are brought in early enough, the level of re-work that is typically done can be reduced substantially. It is always easier to get an engineer to change their mind if they do not have a substantial vested interest in preserving their drawing set. Even if the design is already completed and ready for bid, we can assist by offering smaller, easier to implement changes that can still have a substantial impact on the facility bottom line and tenant and owner satisfaction.
Changes as simple as cooling coil, chiller and cooling tower performance specifications can yield dramatic savings results, without necessitating substantial changes to the drawing set, thus protecting the original Engineer’s sunk cost in developing the drawing set.
Since most engineers are not control system experts, their sequences of operation tend to be very vague, and may only encompass a few pages to cover the entire facility. This vagueness leads to loose interpretation by the control system vendors, and essentially forces the vendor to engineer the controls for the facility with no budget and very little time. This leads to overly simplistic control strategies that marginally accomplish the goals of comfort, mostly ignoring the energy consequences.
We can offer development of complete, concise sequences of operation that are detailed and easy for the control system vendor to understand as a part of our peer review services. There is typically enough information provided in our sequences that flow charts can be developed directly from the write-up.
Additionally, the sequences can easily be modified to allow them to act as a guide for the commissioning process.
When working as a Mechanical Systems Architect, or in a peer review role, we are aware of the “not invented here” syndrome, and the sometimes fragile engineering egos that accompany the HVAC design process. Our ability to be non-threatening and team spirited makes the peer review process less painful for the original design team, and helps to educate them so that less peer review involvement is required on each successive project which they design.
To show how well we are able to become part of the Team, we have actually been retained by Engineering firms to help them on other projects after our initial work with them as Mechanical Systems Architects has been completed.
As a sample of our service in this arena, we offer the following brief discussion of one of our more “high profile” ( pun intended ) projects, the Worlds Tallest Building.
