- Responses are due no later than 3:00 p.m. eastern standard time July 27, 2010. This is a Sources Sought Notice and is for informational/ market research purposes only. THIS IS NOT A REQUEST FOR PROPOSALS, QUOTATIONS OR BIDS. The U.S. Army Corps of Engineers, Baltimore District, requests capability statements from 8(a), Service Disabled Veteran Owned Businesses and HUBZone small businesses concerning the potential project described below. Responses to this sources sought announcement will be used by the Government to make appropriate acquisition decisions. NO SOLICITATION IS CURRENTLY AVAILABLE. Responses are to be sent via email to Regina.M.Wheeler@usace.army.mil or hard copy to U.S. Army Corps of Engineers, 10 S. Howard Street, Room 7200-D, Baltimore MD 21201-1715 no later than 3:00 p.m. eastern standard time July 27, 2010. Project Description: McMillan Pumping Station Upgrades, Washington Aqueduct Division, Washington, DC. The solicitation will be for a construction contract and it will be advertized as an invitation for bid (IFB) in the $1M - $5M range. The work includes electrical, mechanical and architectural upgrades in McMillan Pumping Station to improve plant to extend functional operability. Specific work items include replacement of existing Anvic variable speed drives with latest and state of the art variable frequency drives (VFDs); replacement of valve actuators associated with each pump for surge control; HVAC modifications to the pumping station. There is also minor historic architectural work related to clay tile roofing replacement; window and door replacement; painting and incidental related work. The McMillan Pumping Station serves about 1 million customers daily and is part of a critical water supply infrastructure for the Nations Capital. It must operate reliably in order to guarantee uninterrupted potable water supply to residents and businesses in the Washington, DC metropolitan area. The timing and execution of this project is also critical because the back-up main that covers this service area has developed problems and is in need of immediate repairs. Given the possibility of a catastrophic failure of this major back-up water main, it is paramount that the McMillan Pumping Station stay in service to avoid a disruption of the potable water supply to areas of the distribution system. Therefore, an experienced contractor with resources and expertise to handle the following project constraints is needed: i.Project should be completed in 10 months in order that the repair work on the back-up main can commence. ii.Equipment downtime in the replacement of variable speed drives and surge control for valve actuators should be minimized. At least two of the three existing settled water pumps should be available for operation at all times during the execution of outages. iii.The existing Anvic drives are obsolete and there is no source of spare parts. The project requires relocating all three drives with associated wiring and complex control mechanism to a temporary location and making them operational before installing new VFDs. iv.Roof repair in a high ceiling plant area and climate control from new HVAC equipment should be completed before delivery of new variable frequency drives. Interested 8(a), SDVOB and HUBZone certified firms should submit a concise narrative and specific project examples of similar size and scope that demonstrate their experience in: 1.The replacement of medium voltage variable speed Anvic drives and surge control for valve actuators. 2.The replacement of valve actuators associated with each pump for surge control with electro-hydraulic type actuators. 3.The installation of building HVAC and provision of temporary cooling in case the new HVAC units are not available so as not to delay electrical work on the drives. 4.Roof repair and replacement of the clay tile roofing system. 5.Replacement of historic windows and doors and interior painting. Capability statements should include the following information: details of similar projects, to include demonstrated specialized experience and technical competence in: (a)Performing work within outages of limited duration at a critical infrastructure such as a water treatment plant or pumping station. The contractor shall plan for limited outages to include the relocation of complete lineup of medium voltage Anvic drives in a way that will not hamper the operation of the pumping station. The relocation of these drives to make room for the new VFDs is the most critical aspect of this project. The existing Anvic drives are obsolete and there is no technical service available from the manufacturer, neither are there sources of spare parts. Hence, there are only a handful of engineers available who are familiar with these drives to provide assistance in case of a problem. (b)The selection, installation and operation of medium voltage variable frequency drives. The contractor shall provide VFDs that are most adaptable to the characteristics of the large induction motors and vertical turbine pumps based on performance specifications. (c)Knowledge of different configurations of VFDs and show the ability to convert motor connections to suit the needed application. The contractor shall provide VFDs with the best quality, performance and delivery schedule. (d)Layout for temporary work, safely working around exposed wires, termination and testing of medium voltage cables. (e)The replacement of surge control valve actuator systems serving large motors and vertical turbine pumps. (f)The selection, installation and operation of HVAC equipment. The medium voltage variable frequency drives (VFDs) will not be energized until climate control is achieved within the pumping station. Narratives shall be no longer than ten pages. Email responses are preferred. Comments will be shared with the Government and the project design team, but otherwise will be held in strict confidence. Comments may be in any format, but must include the offerors name, phone number, and email address.
