Statement of Work
Rall Building 101, Module B Basement, Upgrade HTHW pumps seal water temperature sensor
National Institute of Environmental Health Sciences
Construction Request #C102300
COR: Joe Seufert
Date: January 2, 2015
This Scope of Work details requirements for a construction project to upgrade the
existing pump seal water temperature sensor piping in order to install an insertion type
temperature sensor (instead of the existing “strap-on” temperature sensors) on the HTHW
pumps P1 and P2 in Building 101 Module B Basement. The Contractor is to provide all
services for review of existing conditions and construction of the work in accordance with
contract requirements.
The High Temperature Hot Water (HTHW) pumps P1, P1S, P2, and P2S provide HTHW to
the steam generators and hot water converters. Two of the four pumps must be operated
continuously (P1 or P1S and P2 or P2S). Pumps P1S and P2S have already been converted.
I. GENERAL:
A. The Contractor shall provide all services necessary to complete the project as stated
in this Scope of Work (SOW). The Contractor is responsible for providing for
demolition/construction, temporary contractor access, and must maintain
functionality of the existing facility.
B. Period of performance: Final construction must be complete within 90 calendar days
from task order Notice to Proceed (NTP).
C. The Contractor shall provide a Collateral Duty Safety Officer for execution of the
work required in this task order.
D. The Contractor shall provide all project management personnel necessary per their
approved task order specific quality control and safety plans to properly oversee the
construction of this project. Project manager, Quality control manager and
Superintendent roles may be performed by the same individual as deemed appropriate
by the Contractor for this task order provided the designated personnel are qualified
and meet the requirements set forth in the Contractor’s approved Site Specific Safety
Plan and Site Specific Quality Control Plan. The Contractor shall provide for review
and acceptance the resume and qualifications of any key personnel performing the
tasks identified above that have not been previously approved by the Government.
E. Within 10 calendar days of task order NTP the Contractor shall provide a submittal
registry and preliminary schedule for approval.
F. The submittal register shall detail all items to be submitted for Government review
and acceptance. The submittal registry shall include submission dates coordinated
7/28/14

C101267
with the preliminary construction schedule. The schedule should provide minimum
of 10 business days for Government review of each submittal package.
G. Within 30 calendar days of task order NTP the Contractor shall provide a detailed
construction schedule identifying all major and minor features of work including all
closeout documentation required in Section IV of this SOW. The schedule shall be
updated and submitted with each pay request.
II. CONSTRUCTION:
A. The Contractor shall construct the project in accordance with the 2008 NIH Design
Requirements Manual for Biomedical Laboratories and Animal Research Facilities
and in accordance with the FMB-NC Engineering Guidelines and Material
Requirements – Revision D.
A. The Contractor shall comply with the quality control requirements for construction in
accordance with the Contractor Quality Control Program and the contract.
B. Work Restrictions:
A two week notice is required prior to doing any work that will limit the equipment’s
redundancy.
As previously mentioned, two of the four High Temperature Hot Water Pumps
(HTHW) P1, P2, P1S, and P2S must always operate (P1 or P1S and P2 or P2S) to
maintain the building operations. The tie-in timeframe should be minimized (2 hour
maximum).
To replace the piping for this project, the pumps will not be operating and HTHW
isolation valves before and after the pump will need to be isolated, drained and cooled
the day before the work is scheduled by maintenance personnel. The Contractor will
install proper lock out tag out (LOTO) on the isolation valves and pump drive.
III.
SCOPE OF WORK
A. The Contractor shall replace the seal water temperature piping as indicated in the
Figure 1 and 2 with new stainless steel piping and tubing for the existing high
temperature hot water (HTHW) pumps P1 and P2. The new piping arrangement,
lengths, number of elbows, etc. will be the same as what is currently installed on the
existing P1S and P2S.
B. New piping will be ½” 316 stainless steel construction schedule 80 and New tubing
will be ½” 316 stainless steel (1/8” thick) with appropriately specified fittings that are
capable of handling 400 deg / 400 psi high temperature hot water applications. All
exposed piping will be insulated per North Carolina State Building Code.

C. JCI will provide a new high temperature insertion type Kele sensor, transmitter, and
thermowell to match what is shown in the attachments and what is already installed
on P1S and P2S. The existing “strap-on” type temperature sensor will be given back
to the Government. JCI will replace the flexible conduit, conduit body/junction box
and wire back to the JCI panel as needed and will utilize the existing power module
already installed in the JCI panel. Existing programming should not need to be
modified and modifications to existing control diagrams should not be required.
D. As previously mentioned, two of the four High Temperature Hot Water Pumps
(HTHW) P1, P2, P1S, and P2S must always operate (P1 or P1S and P2 or P2S) to
maintain the building operations. When the Contractor is ready to complete the work,
the Government will switch the pumps over to P1S and P2S to allow the Contractor
to complete the tie-in work. The tie-in timeframe should be minimized (2 hour
maximum).
To replace the piping for this project, the pumps will not be operating and HTHW
isolation valves before and after the pump will need to be isolated, drained and cooled
the day before the work is scheduled by maintenance personnel. The Contractor will
install proper lock out tag out (LOTO) on the isolation valves and pump drive.
Following the completion of the work, the new temperature sensors will be
operational.
