4. APPROACH This is also a busy time for mechanical and electrical design as the engineering team will fine tune mechanical and electrical system options, reviewing the best fit for this project. They will update the sustainable design goals, presenting options for reduced energy use or value-added systems. Operational details will be discussed and information gathered on special systems within the fire house such as any pre-emption controls, ramped lighting systems, turnout gear room ventilation, CO monitoring and other detail options specific to fire station design. During design development, the training feature goals set in the programming stage will be revisited, and training features will be selected and positioned within the design with cost, operational impacts for training and response, and multi -use of space all considered. David Acomb will lead a review of the many training elements he has developed for stations around the country, whether comprehensive elements such as those incorporated in the local Roseville Fire Station or simple props using an existing stairwell or corner of an apparatus bay. An outline specification will be produced indicating the material, brand, systems and other product information that has been determined during this phase. The drawing and specification information created during this phase will be regularly passed on to the cost estimating team, allowing them to quickly provide a more detailed cost estimate at the completion of the design development phase. CONSTRUCTION DOCUMENTS Once the design has been established, CNH Architects and our engineers assemble the drawings, specifications, schedules, and details that make up the construction documents. We take pride in developing very comprehensive construction documents with complete, clear information describing the systems and elements of the building to minimize contractor questions and uncertainty in bidding. Providing comprehensive documents also ensures the use of building detailing that has been shown to provide durability and value for past fire station and other public project designs. The fire house will be highly modeled in 3 -dimensions using Revit BIM software. In addition to the main architectural BIM model, all the engineering disciplines also model their designs in Revit. This allows us to link them all together to create a comprehensive model from design development through construction document phases. The engineering consultants are required to build all elements as 3D objects, including smaller items such as light fixtures, power outlets, plumbing faucets, HVAC grilles and structural trussing and braces. This level of detail allows for a high level of coordination between disciplines, ensures clearances for all trades, and validates visual elements of the design. In addition, CNH Architects will conduct collision detection and create visual cuts throughout the combined Revit model, including structure, mechanical, and electrical models near the completion of the project construction documents to locate and eliminate overlapping or incorrectly located building elements. This final quality control step has shown to resolve many potential coordination items that would have been invisible in 2D drafting. Quality control during this phase will also include a final rechecking of the many building codes, accessibility requirements, watershed requirements, and other standards that are applicable to the fire house design as well as a review of client goals and decisions that have been documented during previous phases of the project. As in all previous phases, the cost estimate will be updated a final time prior to completion of the construction document phase, adjusting for changes in systems, quantities, material costs or other bidding environment issues.
