C000 GENERAL

C001 CONTRACT OVERVIEW

The Marine Design Center of the U.S. Army Corps of Engineers (USACE) has issued this solicitation for an

Indefinite Delivery/Indefinite Quantity (IDIQ) Multiple Award Task Order Contract (MATOC). The MATOC contract resulting from this solicitation will support work assigned to the Philadelphia District (NAP) and Marine

Design Center (MDC), U.S. Army Corps of Engineers (USACE), for Electrical and Electronic System Support of existing USACE floating plant nationwide.

C002 DESCRIPTION OF WORK

The USACE currently owns and operates a significant amount of floating plant consisting of approximately 2,500 different vessels. The age of the vessels varies widely, however the majority of all floating plant is at least 15 years old and still operating with the equipment that was installed during original construction. As a result of the age of the vessels, the onboard power, control, monitoring and alarm systems and equipment require replacement several times over the life of the floating platform. In some cases, vessels have undergone planned upgrades to newer systems and components which increases reliability, however it also increases system complexity in operation and maintenance. In other cases, where the condition of the hull and other systems is also in need of significant repair, many vessels have been replaced with newer vessels operating newer electronic systems.

In all cases, equipment operating life, component support, and unpredictable reliability becomes more of an issue with age of the system. Additionally, the complexity of the electronics systems installed in new vessels and retrofitted in existing vessels and their effect on the overall safe operation of those vessels necessitates installation or oversight of installation by recognized system integration experts.
