SAMPLE TASK ORDER

Revision 0.a 6-November-2018

Offerors shall submit a technical approach to the Sample Task Order to include, but not limited to, all equipment selections, interconnection details, point’s lists, sequence of operations, and hardware/software for each control system type (as appropriate per building – see below).

Offerors shall provide System Security Engineering Process information to identify and mitigate system security vulnerabilities. This process shall include a means to ensure the completion of all implementation and acceptance testing required of each control system type with respect to meeting DoD requirements for accreditation and connection to Government networks. Offerors shall clearly state all assumptions where building detail provided is deemed insufficient to provide a complete technical solution. The Government’s intent is to discern the Offerors’s breadth and depth of knowledge in proposing these technical solutions.

1.0 General Assumptions:

1.1 General: The Sample Task Order consists of repair/replacement upgrades in five buildings (100-500) as follows:

B100 Central Plant B200 Marine Reserve Training Facility B300 Child Development Center B400 Electrical Substation B500 Information Systems Facility

1.2 These buildings are located on a fictitious U.S. Army garrison in a region that experiences the temperature variations of al four seasons. Each building is delivered hot/chilled water from the Central Plant; and each, except Building 200, is connected to the post-wide LAN via fiber optic cable. Building 200 is remote and has no LAN communication infrastructure installed.

1.3 Project duration is 24 months to include: surveys, safety plans, engineering, design, submittals, Government submittal review and comments, mobilization, procure and install, Government acceptance testing, demobilization, submittal of As-Built documentation and contract close-out.

1.4 This is a design-build project requiring only a single 100% design package submittal (no interim reviews).

1.5 Air Handling Units (AHU) are equipped with ductwork, actuators and modulating dampers to execute programmed Economizer Cycles (use of outside air for free cooling).

1.6 Work shall be done in accordance with Army construction standards, the National Electrical Code, and American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) standards.

1.7 Work shall be in compliance with latest version of Corps of Engineers, Safety and Health Requirements Manual EM 385-1-1 and Occupational, Safety and Health Agency (OSHA) safety standards.

1.8 All work shall be compliant with Americans with Disabilities Act (ADA) guidelines.

1.9 Offeror shall provide all wiring and conduit required to attach the new DDC system to the facility point of connection in each building which, in turn, will transmit data to the post-wide front-end software/hardware, via Government networks (as appropriate for the individual Sample Task Order building).

1.10 Where available, the Government will provide the network connectivity infrastructure to the local building network switch (IP drop). For building-to-building interconnection, the Offeror’s responsibility to provide communication infrastructure includes the facility point of connection but terminates at the network switch port on each end of the Government owned network segment.

1.11 No upgrades to domestic water heating equipment and systems are required.

1.12 Modify or augment existing equipment if the functionality does not exist to fulfill the requirements of the technical solution.

1.13 There are no hazardous materials.

1.14 Unless otherwise stated, each building has one service entrance for electrical power and one Natural Gas service.
