Iowa City Public Works The City of Iowa City's Public Works (ICPW) consists of seven functional groups or departments. Each of these groups has a specific purpose or mission related to the on-going maintenance of the City's infrastructure, removal and disposal of waste, and/or maintenance of the City's fleet of vehicles and equipment. There is a great deal of interdepartmental coordination and sharing of resources and capabilities. The City worked with Neumann Monson Architects to develop a Master Plan for ICPW in 2015. The Master Plan is to consolidate operations by moving most departments to a single site located at 3800 Napoleon Lane. This will be accomplished in 4 or more phases. Refer to the 2015 Master Plan for additional details regarding programming and other city goals for the complex. The Master Plan is the basis for the Programming document for Phase 1. Phase 1 will provide support spaces for: · Water · Streets/Traffic · Shared Vehicle Washbay · Some police and Fire functions The site is located in the Iowa City South District, between city softball playing fields, a riverside bike trail and Terry Trueblood Recreation Area. Because the building is located between recreation areas and across from a future residential area, the owner would like the public facades to appear less institutional. The “working” side of the site will be buffered by buildings. The site has existing utilitarian structures to remain and others to be demolished. In Phase 1, the existing office building will remain. Pertinent goals of the South District include: · Accentuate South Iowa City's connection to the environment and outdoor recreation. · Provide distinctive landscaping, including low-maintenance native plantings... · Promote energy and water conservation features of new development. Identify buildings or sites that could benefit from solar arrays, reflective rooftops, and other energy/conservation upgrades…. BUILDING DESIGN CHARACTERISTICS The building is seeking LEED Certification under the NC v.4 rating system. It will incorporate the following strategies in its design: · Natural Light · Energy efficient building envelope and MEP systems · Efficient use of durable materials · Low emitting materials · Water efficient plumbing fixtures and faucets 2 Owner’s Project Requirements Several key owner’s project requirements (OPR) have been identified that are critical to the success of this project. These OPR are general in nature and essentially encompass the performance criteria we, the building owners and occupants, desire. We Owner’s Project Requirements 4 have specified the directives contained in this document for the design team. Reinforcing behaviors that reduce energy and water usage, as well as providing information and resources to do so, will be critical to obtaining a high-performance building. · Project documentation requirements – in order to properly install, start-up, operate, troubleshoot, and maintain the HVACR systems for the life of the facility, accurate and accessible documentation is required. The owner requires all documentation to be electronic and tailored to the specific components installed. · Appropriate heating and cooling - The HVACR system must provide consistent temperature and airflow during all occupied periods. Must be capable of temperature setbacks based on schedules and occupancy sensors. · Efficient and adequate work space - The spaces must be designed to provide ample work and support areas to facilitate the operations of the building rather than hamper them. · Sustainability - The design and construction of the building must take into account all long term and life cycle issues. The building systems must be easily maintainable by contracted maintenance personnel, with easy and non-disruptive access to components and systems for routine maintenance. 2.1 HVAC Systems All systems will utilize a central Facility Management System (FMS); this is related to the maintainability OPR, whereby using a common control system will simplify the operation of the facility. · Appropriate heating and cooling: Regularly occupied spaces: the HVACR system must provide consistent temperature and airflow during all occupied periods. Vehicle Storage and Mezzanine: the HVACR system must maintain the system above freezing at all times, mitigate summer temperatures, provide code compliant air flow and provide safe indoor air conditions through management of potentially hazardous gas concentrations. 2.2 Lighting Systems All lighting in the building will be LED. Lighting systems will be designed with photocell control in areas with daylight access. Lighting connected to lighting control panels and/or on-off photocells shall have the ability to be controlled by the building Facility Management System (FMS) Lighting controls will be provided to balance user control (dimming, on/off) with energy efficiency goals, zoning and code requirements. High bay fixture shall be selected and located to provide adequate light levels and uniformity in the vehicle storage area as specified by the IES. Exterior lighting will be controlled with time clock scheduling and photocell override. To preserve dark skies and limit light trespass at the property line, all exterior fixtures shall be low glare type as specified by LEED. 2.3 Building Enclosure Durability should be a primary consideration in material selection. The building will be subject to stresses from interior exposure to vehicles, oil, water, salt, dirt and diesel fumes. The life expectancy of the overall enclosure is 100 years, 30 - 50 years for windows and doors. 20 years for overhead doors. Owner’s Project Requirements 5 A high performance envelope that exceeds code minimums: IBC 2015 and IECC 2012. Source materials with regional and recycled content. Materials on the interior of the weather barrier shall meet the General Emissions Requirement. Wet applied materials shall also meet the VOC restrictions described in LEED-NC v4 EQ Low Emitting Materials credit. The Master Plan calls for a future addition on the North and at the southern portion of the west facade. Select enclosure which will accommodate these future additions. Thermal and air barrier to be reviewed for continuity as part of the Construction Document review process. Balance goals for an energy efficient enclosure and access to daylight with a target of 20-25% window to wall area ratio. Roof durability goals: cover board to increase durability, walking pads, extended warranty. 2.4 Commissioning The City of Iowa City will directly contract a third party Commissioning Authority (CxA) The CxA will provide a quality- oriented process for achieving, verifying, and documenting that the performance of the facility, systems, and assemblies meet the defined objectives for achieving the criteria as defined in this document. Commissioning (Cx) a building is essential to ensure that building performance requirements are identified early in the design process, and that the designed systems have been installed in compliance with those requirements. The CxA will collaborate with the design and construction teams to provide the following: 2.4.1 Fundamental and Enhanced Commissioning Scope of Work Specifically, the CxA will take the following actions: · Review the OPR and Basis of Design (BOD) for clarity and completeness. · Conduct and document a commissioning review of the design documents at mid design (~50% CD) as required by LEED. o Reference alignment with the OPR and BOD documents. o Review the proposed mechanical and envelope systems design for function and completeness. o Confirm system manual and training requirements are included. o Document and provide concerns, issues and suggestions to the design team and owner. · Conduct a follow up back-check review of the subsequent design submission. · Work with the team to prepare and provide commissioning requirements to be incorporated into the project delivery method. · Include Systems Manual and training requirements in contract documents. · Develop a Commissioning Plan. · Develop Pre-Functional “Construction Checklist” forms.
