Plumbing systems design
Third party design reviews
Although our “product” is construction drawings, our real product is our ability to design highly efficient mechanical solutions. Ideally, architects and contractors involve us early in a project, preferably in the conceptual stage. We provide valuable input on the mechanical systems and make recommendations on materials, methods, and constructability. When making recommendations, we always consider budget and schedule as well as energy efficiency.
Our team can provide as little or as much design assistance as needed. In some cases, we provide project management to guide the architect or general contractor in the integration of the mechanical and plumbing systems. For instance, for a large custom home we might coordinate the design and integration of the radiant floor distribution, domestic hot water, duct distribution and other peripheral systems such as pool/spa heating or wine storage.
Plumbing systems design
Our plumbing design services include domestic cold and hot water, sewer, vent, and natural gas / propane distribution systems. Designs include plumbing plans, isometrics, installation notes, and schedules. While design-build contractors can provide their own drawings for permit, our experience has shown that our plumbing design format and knowledge of the plumbing code expedites both the permit process and the installation. We also provide hydronic piping designs. This service is covered under our HVAC system designs and usually consists of a piping plan, system schematic, and sequence of operation.
If an owner is unsure about the type of HVAC system to install, we can provide a feasibility study that compares several designs or systems to determine the lowest life cycle cost. Considerations include cost of power, construction budget, maintenance and building usage. In preparing the study, we research the availability of utility rebates or tax incentives that might lower the cost of the installation.
Information required to prepare a feasibility study include:
Cost of energy or one year of power bills for an existing building
Types of mechanical systems to be compared
For existing buildings, history of maintenance costs (if available)
Any special considerations different from standard operating conditions
