Z--528A8-16-807 Design Repair Parking Lots Phase 1

The primary reason for the project is that there is a low spot in the parking area that is subject to persistent flooding, which has resulted in damaged vehicles. The flooding has been exacerbated by an ineffective drainage system within the parking lot as well as the City of Albany s combined sewer, which bisects the parking lot, being undersized and unable to remove rain water during high intensity events. So, the primary objective is for the Architect/Engineer (A/E) to design an adequate drainage system that will be a combination of regrading, new drainage structures and storm water runoff storage. The VAMC commissioned a study of the parking lot in 2012 that was to determine the cause of the problems and provide recommendations. In addition to flooding, there are other issues with the current parking lot that need to be addressed in the repair design. These are: Failing/inadequate pavement: There are several areas within the parking lot and access lanes where the existing pavement is failing. It appears that this is due to inadequate subbase for the in-situ soils. All of the paving needs to be removed and replaced with appropriate subbase, geosynthetic fabric and soil reinforcing grid. A soil analysis and recommended pavement cross section was prepared by Tectonic Engineering & Surveying Consultants as part of a previous project. That report has been included in the reference material provided. Damaged power cabling to light poles: The power feed to the existing light poles has been damaged in some areas. The design must incorporate determining the location of the damage and correcting it. It is assumed that the design will require that the existing light poles will be moved to maximize parking and that new feed cabling will be installed. The A/E may elect to add lights as well to provide a safe lighting level. Access gate sensors: The parking gate vehicle sensors in the pavement need to be replaced as part of this project. Abandoned water line: There is an abandoned water line in the parking lot that must be removed back to the meter vault as part of this project. Physical Security Improvements: Some low-tech barriers will need to be included in the design, which will be described by the VA Police during the design process. Phasing: The area of work is the major parking facility for the VAMC. The A/E must phase the work such that some parking will be available during construction. The employee lot is generally at capacity during the week. Thus, the amount of on-site parking must be maximized since arrangements will need to be made for off-site parking during construction for any displaced spaces. The A/E shall perform all work necessary to prepare the specifications, drawings and construction bidding documents for the subject project. Throughout the design phase, the A/E shall produce and maintain all meeting minutes. Also, the A/E shall perform an Environmental Assessment per NEPA requirements and the historical assessment to interface with SHPO. The A/E also must coordinate the design and construction process with the City of Albany Water and Water Supply Department to address concerns that they may have. The A/E shall also perform construction bidding and construction period services as noted in section E.
