C1DZ--A&E Replace Boilers Building 14 Project 542-23-101 NCO 4 Construction Central

classified as 100% SERVICE-DISABLED VETERAN-OWNED SMALL BUSINESS CONCERNS in response to Replace Boilers, Building 14 project via electronic mail to elizabeth.wilson6@va.gov. GENERAL SCOPE OF WORK: The consultant shall provide all architectural and engineering services as defined to accomplish complete contract drawings, specifications, technical reports, and cost estimates for the scope of work. Existing Overview: There are four existing watertube boilers in Building 14. Boiler #4 was recently inspected and failed due to deteriorated tubing in the boiler. Operation of Boiler #4 is prohibited in its present condition. Remaining boilers are near the end of their useful life and are also in need of replacement. There is also a leaking condensate tank which needs to be replaced. Scope of Work: The principal objective is to remove existing boilers and replace with new appropriately sized firetube boilers. The scope includes provisions for the following: This project replaces boilers in the existing boiler plant as phased construction, while maintaining active boiler plant operations. During the full extent of the project, N+1 boiler must be maintained online and fully functional. Sizing of the new replacement boilers shall be calculated/documented and closely coordinated with the COR and submitted to the VA for approval prior to the 25% Schematic Design submission. Temporary boiler stub-outs will be provided by a prerequisite project to allow for the N+1 criteria to be maintained with a temporary boiler during existing boiler removals and new boiler installations. This prerequisite design shall include appropriate sizing, hook-up piping/valves, controls, start-up etc. to maintain a fully functional temporary boiler plant during demolition and installation of new boilers. Design shall include, but is not limited to, all connection points for gas, fuel oil, boiler feed water, condensate return water, electrical power, and controls for both the temporary boiler and new replacement boilers. Design shall include the replacement of the existing steam header in the boiler plant and reconnection of existing and new boilers with individual block valves for isolation of each boiler. Design shall include the removal and replacement of an existing condensate tank all necessary piping, valves, fittings, controls, and equipment needed for a fully functional condensate return system. Design shall not include cameras for monitoring the temporary boiler and all associated monitors, wiring and programming required for a fully functional temporary boiler system. This will be designed under a separate contract prior to execution of this contract. Design shall not include modifications to the facility for a vestibule to facilitate a line of site viewing of the temporary boiler. This will be designed under a separate contract prior to execution of this contract. Design shall not include any driveway repairs or removable protective bollards, or walls/barricades as needed to prevent any damage to the temporary boiler installation, or any associated site work needed for any portion of this scope. This will be designed under a separate contract prior to execution of this contract. The AE shall include design work required to relocate the existing gas and fuel oil lines to above the concrete slab floor for ease of access and maintenance. The AE shall provide individual stub stacks for each new boiler installation while maintaining the existing vent system and stack fully functional for the existing two boilers to remain. The AE shall include design work to provide new tie-off points to safely access the existing exhaust fans and for access points above both new and existing boilers. The AE shall provide design for the replacement of the existing fuel oil transfer package with a new duplex fuel oil pump package. The AE shall include design work to replace all existing corroded feedwater piping from the deaerator pumps to both new and existing to remain boilers. The AE shall include design work to provide for the replacement of the existing lift pumps. The work shall include the removal of the existing lift tank and replacement with a larger tank in addition to a new 4 pump header replacement. The AE shall include design work to replace the existing brine supply piping to the polisher with new piping of equal size. The AE shall include all necessary boiler controls for a fully functional system and tie the alarms/status/monitoring signals back into the existing graphic display system to match the existing (typically 4 to 20 mA) signals currently displayed on graphics. All work shall be in full compliance with all applicable VA standards and code requirements except as follows: The design of replacement boilers shall not be subject to the requirements of the VA Physical Security and Resiliency Design Manual. The AE shall assist in obtaining the necessary EPA and emissions reviews and permits required prior to construction. The AE shall outline a plan including all permitting and associated costs required prior to and during construction to the COR for review and discussion with the AE as part of the 25% Schematic Design submission. The A/E shall incorporate into their design period of services fees for a third-party Commissioning Agent with regards to design, start-up, and commissioning of a boilers. The Commissioning Agent shall review all design submissions prior to submission to the VA and review all responses to VA review comments prior to submission to the VA. The third-party Commissioning Agent shall be agreeable to both the A/E and the VA before being contracted by the A/E. It shall also be necessary for the Commissioning Agent agreed upon to be active with the actual design of the new boilers and other associated systems and related work. The approved Commissioning Agent shall have prior experience directly related to the design and start-up of similarly sized firetube boilers and hold a professional engineering license in good standing with the State of Pennsylvania licensing board. The A/E shall not act as their own Commissioning Agent. The AE shall insure that all spare parts of boilers removed are retained as recommended by the Chief Boiler Operator and approved by the COR. The scope of work includes but is not limited to the following: Evaluation of existing conditions, Site analysis and programming and design charrettes as required, All associated life/safety modifications, Modifications to all building systems and utilities as required for the new boilers. Note: The building is currently not sprinklered and the addition of a sprinkler system is not required. Providing recommendations and cost estimates at each submission, Implementing value-engineering decisions to meet required construction budget, Creating a phasing plan for the installation of a temporary boiler, removal of two existing boilers and installation of two new boilers. The phasing plan will maintain the N+1 operating requirement and allow the boiler plant operation to continue, uninterrupted, throughout the entire construction period of the project. Providing submissions and final documents as indicated below. The Following Investigative Work shall also be included within the Scope of this Project: Perform a Code analysis to ensure that the applicable Codes are being applied. Provide any civil, structural, archit
