Re: NuMI Project, Davis-Bacon Determinations

The NuMI Project provides for the construction of an intense, variable
energy, beam of neutrinos using the Fermilab Main Injector, as well as
large underground neutrino detectors located at Fermilab and Soudan,
Minnesota. The purpose of the Project is to enable a new generation of
long baseline neutrino experiments that can decisively detect and
accurately measure neutrino oscillations. Detection of such oscillations
would firmly establish a non-zero value of neutrino mass. The scope of
the NuMI Project includes the excavation of large underground spaces to
house the neutrino beam system and associated near and far MINOS
experimental detectors.

NuMI Project Management is fully aware of Davis-Bacon Act applicability
to new construction and installation activities that are Federally
funded and is committed to meet the letter and intent of the Act in its
application to the NuMI Project.

This memorandum serves to outline the NuMI Project's request for
Davis-Bacon determinations for three distinct broad areas of activity.
These are 1) the construction of physical structures and excavation and
outfitting of underground areas, 2) the installation of technical
components (WBS 1.1) that comprise the neutrino beam system, and 3) the
installation of the near MINOS experimental detector (WBS 2.5). I ask
for your concurrence with the Project's request and that you submit same
to the Department of Energy for determination. I am clearly open to any
related suggestions that you may offer and I assure you that Project
staff are available for additional clarification or discussion as
determined necessary.

While the majority of construction and installation labor efforts
afforded to the NuMI Project are designated for Davis-Bacon subcontract,
there remain a limited number of specialized labor activities relative
primarily to installation of technical components that are best
designated as noncovered under Davis-Bacon. In distinguishing these
activities, NuMI Project Management has used the following approach:

> • If the craft skills required by the task in question are closely
> coupled with or normally used in the construction of the facility and
> installation of the system, the work is designated for Davis-Bacon
> subcontract. Examples include land surveying, excavation, concrete

In further distinguishing these activities, NuMI Project Management has
relied on the criteria specifically set forth in Department of Energy
Acquisition Regulations relative to particular work items that will
normally be classified as noncovered by the Davis-Bacon Act. DEAR
970.2273(a)(3) allows as noncovered work the assembly, modification,
setup, installation, replacement, removal, rearrangement, connection,
testing, adjustment, and calibration of machinery and equipment. DEAR
970.2273(a)(4) allows as noncovered work the experimental development of
equipment, processes, or devices including assembly, fitting,
installation, testing, reworking, and disassembly.

The following briefly describes the general scope of work for various
WBS categories together with selected installation activities for which
Davis-Bacon exemption is sought. These activities are judged by NuMI
Project Management to be suitable for designation as noncovered
Davis-Bacon activities in light of the above criteria and precedent.
On-going work activities on the part of Fermilab personnel related to
supervision of covered Davis-Bacon work are not specifically listed.
Verification of operability and commissioning activities are also not
specifically listed. Estimates of hours of work required have been

> Hours)

**Generalized Justifications for Noncovered Davis-Bacon Work
Activities**

DEAR 970.2273(a)(3) allows as noncovered work the assembly,
modification, setup, installation, replacement, removal, rearrangement,
connection, testing, adjustment, and calibration of machinery and
equipment. This generalized allowance for noncovered work is reasoned to
apply to the following NuMI Project activities.

**G1** Installation, connection and setup of technical equipment in
equipment racks. Examples of equipment in this category to be installed
and connected include electronic crate systems such as VME, CAMAC, NIM,
trim element power supply bins, and CIA and the modules inserted into
same. Also included are multiplexed A/D converters (MADCs),
oscilloscopes and test equipment, instrumentation processing
electronics, device positioning systems, programmable logic controllers
(PLCs), CATV monitors, ACNET consoles, network and controls signal
repeaters, fiber optic cable field termination and routing enclosures.
Also included here are the installation and connection of incidental
inter-rack wiring and cabling within controls areas of service buildings
and enclosure. Proper performance of the activity requires detailed and
unique knowledge of the technical equipment and its relation to
particular subsystems that are essential and unique to the accelerator
complex and the neutrino beam system. While reasoned to fall under DEAR
970.2273(a)(3) exemptions, these activities are also best and reliably
performed by Fermilab personnel.

**G2** Field installation, connection and setup of other technical
equipment. Examples of such activities include connection of LCW cooling
hoses, cabling to beamline components such as magnets, kickers and trim
elements, beam target, and focusing horns; and also to instrumentation
such as hadron and muon monitors, CATV, FIRUS, water system transducers
and process instrumentation, BPMs, beam intensity toroids, multiwires
and loss monitors. While reasoned to fall under DEAR 970.2273(a)(3)
exemptions, the proper performance of the activity is also essential and
unique to correct operation of the equipment and are best and reliably
performed by Fermilab personnel.

Other generalized justifications for noncovered Davis-Bacon work
activities are as follows:

**G3** Selected technical equipment scheduled for installation
represents unusually high dollar value, uniqueness, first of a kind or
state of the art designs, fragility, especially demanding placement
tolerances, specialized installation skills, and less than readily
available replacements or some combination thereof. Examples of such
equipment include the three primary beam extraction kicker magnets, the
beam target, the two magnetic focusing horns, the horn power supply, and
the stripline connection between the horn power supply and the focusing
horns. Proper installation of such equipment is readily categorized as
mission critical and represents a material factor in the timely
completion of the NuMI Project. The unique experience and technical
qualifications of Fermilab personnel performing the work are demanded so
as not to jeopardize the equipment, its availability, its proper
functioning, its reliability, or the success of sub-system start-up.

**G4** Selected areas of installation activities involve technical
equipment or apparatus that will become highly radioactive once the
neutrino beam system comes into operation. These activities demand an
extremely high degree of care and attention to detail so as to preclude
early failure of the equipment or apparatus, necessity of re-work or
untimely repair. Examples include installation and connection of the
beam target, magnetic focusing horns, RAW systems and containment
structures, radioactive air containment systems, decay pipe end caps,
hadron monitor detectors, and the beam Absorber. The installation of
regular and total loss monitors in the primary beamline is related to
this general category. Proper placement of these monitors is essential
to minimizing radiological activation of components and groundwater. If
such re-work or repair would be necessitated, the consequence would
involve increased radiation exposure for workers and significant
downtime to experimental operations. These activities often involve the
direct involvement of radiation safety personnel. It is essential that
such activities be reliably and successfully performed by experienced
and qualified Fermilab personnel.

**G5** The 980 metric ton near MINOS experimental detector is composed
of iron-scintillator sandwich calorimeters, with toroidal magnetic
fields in their thin steel plates. Specifically there are 282
iron-scintillator planes being comprised of 955 metric tons of steel and
25 tons of scintillator material. This combination has been used in a
number of previous neutrino experiments. The MINOS innovation is to use
scintillator with sufficiently fine transverse granularity so that it
provides both calorimetry and tracking information. Inclusive with the
experiment is the particle flux information afforded by both hadron and
muon detector instrumentation in the Hadron Absorber area. This
instrumentation, together with its associated data streams, is used by
the near detector in conjunction with generated experimental data.

The fabrication and assembly of the MINOS near detector is clearly
experimental apparatus and, as such, is not subject to the Davis-Bacon
Act. The near detector is not a permanent part of the Laboratory's plant
and property. There has been longstanding agreement between the
Laboratory and the Department of Energy that such experimental related
activities are noncovered. (Reference memorandum of August 22, 1972 from
Fred C. Mattmueller, Area Manager, to Dr. Robert R. Wilson, Director)

Provisions for the construction of buildings, tunnels, and utilities,
and modification of utility services for experimental purposes are
recognized as covered activities. These activities are distinguished
from those that involve temporary connections to the utility services
and are noncovered. It is acknowledged, nonetheless, that certain post
beneficial occupancy installation of temporary connections will likely
be executed by non-Fermilab trade and craft personnel under subcontract
to the Laboratory. These activities, involving approximately 900 hours
of effort, will primarily involve finishing of electrical premises
wiring, pipefitting and some welding.

# Specific Justifications for Noncovered Davis-Bacon Work Activities by WBS

## WBS 1.1.1 **Primary Beam**

**1A** Each of the three extraction kickers magnets each contain an
especially long ceramic beam tube. Given that these tubes are no longer
readily available from the past vendor, the tubes used have been
salvaged from a very limited supply of excess equipment. In fact, there
are only two such tubes remaining and they are of lesser quality in
terms of aperture. These kickers are scheduled for installation in 2004
and providing replacement(s) in time for beam commissioning would be
extremely difficult if not impossible. If any of these tubes would
suffer damage during installation, there would be a major set back to
the Project's schedule. It is essential that these elements be installed
by Fermilab personnel familiar with the specialized techniques and
handling procedures for such devices.

**1B** The transport of certain magnets in the Main Injector enclosure
requires utilization of a custom built magnet mover. Operation of this
magnet mover is limited to selected qualified Fermilab personnel.

**1C** A minority of magnetic elements in the primary beamline are
supported from either the enclosure wall or ceiling. There has been long
precedent for Fermilab personnel to load test such stands as both
quality assurance of mounting method and as fulfillment of required
safety tests. These load tests are best performed by independent
Fermilab personnel.

**1D** Flourinert is used as a cooling fluid for the extraction kicker
magnets. The system being installed is a first of a kind design for the
Laboratory. Cooling of the flourinert fluid is a necessary process that
serves to minimize the chemical breakdown of the fluid into dangerous
compounds. Proper operation of the cooling system is essential in
preventing damage to the extraction kicker magnets themselves. The
proper mechanical installation of the flourinert cooling system is best
accomplished by Fermilab personnel who have been involved with its
development.

## WBS 1.1.2 **Neutrino Beam Devices**

**2A** Development and practice of radioactive component handling is a
scheduled activity in the Target Hall before beam commissioning. The
Project anticipates failures of certain highly radioactive neutrino beam
system components, notably the beam target and magnetic focusing horns.
The handling, replacement, and possible repair of these highly
radioactive components will be performed by specially qualified and
knowledgeable Fermilab personnel. It is essential that they develop and
practice related procedures so as to adequately and efficiently perform
anticipated tasks with a minimum of personal radiological exposure. This
exercise, that is practiced with the actual high value beamline chase
components, may demand field modification of apparatus especially
designed for the work on an as needed basis. These activities are
reasoned to fall under DEAR 970.2273(a)(4) exemptions that allow as
noncovered work the experimental development of equipment, processes, or
devices including assembly, fitting, installation, testing, reworking,
and disassembly.

# WBS 1.1.3 Power Supplies

**3A** Various power supplies have been procured from available Fermilab
spares. These supplies typically require some level of construction,
modification or assembly so as to be suitable for operation. This work
is often best accomplished at the place of final installation due to
power supply size and/or lack of availability of other off Project site
working space to perform the work. Such work is highly specialized and
not normally performed by craft personnel. These activities are best
performed by specially qualified and knowledgeable Fermilab personnel
who are familiar with associated power supply technology.

**3B** Some of the required power supplies will be tested with dummy
loads in-place on the Project site. This testing serves to validate
supply design prior to the commissioning process. This testing activity
is best performed by specially qualified and knowledgeable Fermilab
personnel who are familiar with the associated power supply design and
technology.

# WBS 1.1.4 Decay Region and Hadron Absorber

No specific justifications are thought necessary for this WBS.

# WBS 1.1.5 Neutrino Beam Monitoring

**5A** As mentioned in Generalized Justification G5, the hadron and muon
detector systems designed and constructed under this WBS are considered
as part of the experimental equipment. Installation activity is
accordingly reasoned to be noncovered under Davis-Bacon.

# WBS 1.1.6 Survey, Alignment & Geodesy

**6A** Alignment management, supervision, and actual field work during
the alignment of technical components of the neutrino beam system is
closely linked to the accelerator physics of the beamline, the
experimental physics of both near and far MINOS detectors, the design of
the alignment systems, and the as-built conditions of the enclosures.
This alignment by its nature must be performed by professional personnel
who understand the machine and experimental physics demands, component
functions, alignment system design, alignment equipment limitations, and
especially the data which represents the installed conditions in the
enclosure.

Alignment of the neutrino beam system starts with the establishment of
an overall control network which covers the entire geographical area of
construction and installation. The design of this control network is
based on the configuration of the neutrino beam system, the relationship
to the Main Injector accelerator and the MINOS far detector, the
placement of individual components in subunits, machine physics
tolerances on component locations, and the capabilities of the equipment
available to perform the actual alignment steps. This alignment
equipment includes computer controlled electronic theodolites and laser
distance measuring devices.

Machine physicists perform computer based beam optics/magnetic
calculations which are the design criteria for the alignment personnel.
Extensive parametric studies are performed on these beam optics
calculations to determine the beamline lattice, component operating
requirements, as well as component locations and their tolerances.
During the design process, alignment personnel maintain a close
interface with the beamline physicists to insure proper implementation
of the beam optics design. The alignment personnel convert the beam
optics computer output into \"real\" numbers to be used in the beamline.
These numbers are determined relative to the control network designed by
the alignment personnel. This process describes what can be called the
\"alignment design\" which precedes installation and actual alignment
work adjusting components in the enclosure.

During the actual installation/construction phase, alignment personnel
will perform or supervise directly the following activities:
installation of monuments in the enclosure floor or walls, surveying the
surface network, surveying the enclosure control network, locating
hardware supports, pre-aligning magnets and beam diagnostic equipment,
and final alignment of the entire accelerator/storage ring complex. All
these activities are driven by the beam optics requirements to locate
many hundreds of components to tolerances that are typically within
0.010 inches. Relative location between selected components is often
more stringent in tolerance. In the face of these requirements,
alignment personnel must cope with fabrication tolerances on the machine
components as well as conventional facilities that vary greatly. In the
enclosure, some portions of concrete structures will move or settle
significantly in the early years of the Project when installation
occurs. Even after the enclosure is initially stabilized, it will
continue to move as the beamline is commissioned and brought into
operation.

Because of the conflict between the precision required for successful
alignment of beamline components and the real environment of the
beamline enclosure, it is essential that the alignment professionals
oversee the installation of their alignment system, do the actual
adjustments, and collect the alignment data in order to be able to
interpret the conditions that exist in the beamline. Their environment
is one of continuous iteration to achieve the final physics requirements
of the beamline. Even temperature fluctuations in the enclosure can
affect the accuracy of the alignment process. The physics requirements
themselves are frequently not finalized until late in the construction
phase. It would be extremely difficult, if not impossible to define the
details of the beamline alignment so that it could be subcontracted,
even if a lengthy training program for subcontract personnel were
initiated. Frequently, the final alignment step in a beamline is the use
of actual beam performance to adjust components to achieve proper
beamline operation. Such a process is clearly envisioned for the
neutrino beam system.

Finally, precision alignment and realignment will be a continuing
process throughout the life of the MINOS experimental program. Over the
years, settlement of some portions of the enclosure will occur and
necessitate realignment. Any future modifications to the neutrino beam
system will require alignment to existing components.

The particular requirements of survey and alignment activities demanded
by the NuMI Project, as outlined above, are best executed by Fermilab
personnel uniquely familiar with the activities required.

# WBS 1.1.7 Beamline Utilities

**7A** Hydro testing of both LCW and RAW systems is common practice to
verify acceptance of subcontractor work. Water cooling is an essential
utility that affords proper operation of varied technical components,
some of which are of especially high value. RAW systems are especially
critical given the potential for radioactivated fluid release. Care must
be taken in the testing activity to isolate selected devices that may be
damaged by the test. Hydro testing of installed water systems is best
performed by independent Fermilab personnel who have experience in this
type of testing procedure and who are knowledgeable in the particular
design of the system under test.

**7B** Various vacuum systems and especially the primary beam vacuum
system are acceptance tested by performing a helium leak check in
accordance with standard Fermilab leak check techniques and by qualified
Fermilab vacuum technicians. The integrity of welds and mechanical
connections are verified. The highly specialized testing equipment
required would not normally be available to construction contractors but
is currently part of the complement of Laboratory property. Likewise,
helium leak checking techniques would not normally be included in the
range of skills of construction contractor personnel but are a normal
requirement of Fermilab vacuum personnel. Testing vacuum systems for
leaks using helium detection techniques are best performed by uniquely
trained and qualified Fermilab personnel.

**7C** Selected primary beamline components, especially including the
Lambertson magnets, require bakeout at elevated temperatures to achieve
desired levels of operating vacuum. Successful bakeouts require careful
attention to the process and monitor of the vacuum system during the
bake. Such activities are successfully and best executed by qualified
Fermilab vacuum technicians.

# WBS 1.1.8 Controls, Interlocks and Cable Installation

**8A** The FIRUS system, unique to Fermilab, involves installation of
specialized equipment that serves to monitor remote fire detection
systems for life safety and critical utilities. The CATV system is also
unique in it layout and distribution. Certain aspects of the CATV
installation will involve life safety by monitoring conditions in the
underground enclosures. Installation must also take into account signal
and amplifier levels for proper operation. Installation activities
associated with these systems are best performed by qualified Fermilab
personnel familiar with these systems.

**8B** Much of the modifications and installation relating to the Main
Injector and NuMI Radiation Safety Systems is provided by electrician
craft personnel by conduit placement and cable pulling. Termination and
connection of safety system cables, installation and alignment of
selected components of the safety interlock system, connection of
critical devices, and placement and alignment of selected gates and door
switches are unique activities best performed by Fermilab personnel
familiar with the design and proper installation techniques. This work
is extremely critical to the proper operation of the Radiation Safety
Systems and has a strong life safety component. Work on these systems is
procedurally limited to specific Interlock Group personnel in the Beam
Division\'s ES&H Department.

**8C** Terminations for a select group of cables require specialized
connectors and/or tooling. Proper termination of the RG220 high voltage
cables for the extraction kickers involves phase matching (ref. 8D) is
especially important given the uniqueness and criticality of the
extraction kickers themselves. These termination activities, while not
represented by a great number of hours of work, are best performed by
Fermilab personnel practiced in appropriate techniques.

**8D** Termination of some 54 Andrew Heliax cables is not an easy or
straightforward task. This is a specialized activity best performed by
Fermilab personnel familiar with developed techniques and procedures.
Proper operation of BPMs, and the intensity and total loss monitors is
essential to proper and safe operation of the primary beam line.
Additionally, the two cables per BPM must be trimmed and cut so as to
have exactly similar electrical lengths. This task requires the use of
specialized electronic measuring equipment to achieve this
characteristic. Subcontractors generally do not have the personnel with
the required electronic skill level or the advanced electronic equipment
to accomplish the task. Incorrect termination could cause system errors
that could result in false readings of actual beam position.

# WBS 2.5 Near Detector Installation

No specific justifications are thought necessary for this WBS.

NuMI Project Management requests a timely review by your office and the
DOE of the aforementioned work activities and a subsequent determination
of suggested activities to be noncovered work under the Davis-Bacon Act
as allowed by the DEAR criteria. In that review, Project Management
requests due consideration of previous determinations that relate to
similar work activities both at Fermilab and at similar facilities in
the DOE complex such as the APS at Argonne. Special consideration is
