Procedures for public bidding requires that the final government cost estimate
for each project be opened and posted as a bid for each project as the first bid
opened before the each of the contractor's bids are opened and posted. If the
lowest contractor submitted bid is too much higher or too much lower that the
Final Government Construction Estimate prepared by the AE design firm (such as
Gerald Spencer) then the contract cannot be awarded, and/or review and
justification of the bid to the Final Government Construction Estimate must be
performed. For the 300 federally funded projects where Spencer Engineers, inc.
prepared the Final Government Construction Estimate, all of these projects were
able to be awarded. A list of cost estimating results can be derived to
determine the accuracy of the Final Government Cost Estimates that were prepared
by Gerald Spencer, P.E. compared to the low bidder on the project. Gerald
Spencer has not ever had a Federal Government project where the low bid was too
high above the Final Government Cost Estimate for the government to award a

24.
ENERGY CONSUMPTION MANAGEMENT
ISSUES: Gerald Spencer has 40 years
experience preparing formal Life Cycle Cost Analysis (LCCA) studies and formal
reports for making economic decisions that determine the best economic decisions
for the design and configuration of large energy consuming HVAC and heating
systems for building facilities. Most of these facilities were large Federal
Government projects. Gerald Spencer
has experience in the design of radio control of electrical loads for the
purpose of load shedding to reduce electrical demand charges and power factor
correction system modifications. Gerald Spencer has prepared formal reports to
justify the expenditure of funds for sometimes small improvements to existing
facilities or new construction efficiency improvements. These reports take into
consideration all capital investment, operating costs, taxes, interest,
maintenance and replacement costs on a life-cycle cost analysis basis. Gerald
Spencer has in-house capability and experience in preparing energy budgets and
energy analysis by computer modeling. Gerald Spencer always approaches energy
engineering with an open mind, and evaluate every conceivable energy savings
option. Gerald Spencer, P.E. can become available to perform as a legal expert
witness for energy consumption issues. Gerald Spencer has the following energy
analysis capabilities with his in-house data processing systems.
24.1.
COMPUTER PROGRAMMED ENERGY
CONSUMPTION MODELING: Gerald Spencer,
P.E. provides energy consumption calculations by computer modeling each building
that is planned. Once we have this data inputted into our computer, we can
easily ask "WHAT IF” questions concerning not only the equipment selection,
operation, and configuration, but also questions concerning the construction or
modification of the building. We can provide a computer programmed energy
consumption simulation model for any building using our in-house computer.
Existing Projects that have records of utility consumption and costs will allow
us to vary the inputs of lights, people, and other variables until the energy
consumption matches the historical data from the utility billings for a very
accurate projection of future energy consumption with any proposed
modifications. This will allow us to ask “WHAT IF” questions, and get finite
energy savings in BTU, KWH, KVA, from any and all proposed energy related
modifications to the building. Typical proposed considerations will be in the
following areas, plus others that we think of when we get into the project.
24.2.
KVA DEMAND CHARGE REDUCTION:
Gerald Spencer, P.E. can provide automation for load shedding as required to
reduce KVA demand charges by the power company. This will require a system to
monitor the KVA demand at the incoming electrical service with pulse meters that
will constantly up-date a controller as to the present KVA Demand that is the
basis for the electrical demand billing. This Controller will cycle various
loads off for relatively short periods of time so that the total measured demand
at the point of metering is reduced. The various loads will each receive a
priority rating and the controller will selectively cycle the various loads at
different times as required to reduce KVA Demand. This will be a part of the
EMCS, SCADA, or UCS system.
24.3.
INCANDESCENT LIGHTING:
Gerald Spencer, P.E. always tries to
minimize the use of incandescent lighting by substituting florescent (or HID)
lighting to provide the same lighting levels with less wattage of energy usage
everywhere possible.
24.4.
LIGHTING LEVELS:
Gerald Spencer, P.E. will review lighting levels in the site and justify any
levels that are greater than the minimum requirement.
24.5.
INSULATION:
Gerald Spencer, P.E. will consider different thickness’ of Roof Insulation and
Wall Insulation if economic life cycle cost analysis can justify the capitol
expenditure.
24.6.
WINDOWS:
Gerald Spencer, P.E. always considers the following glass options:
Different Reflective coatings
Double pane insulating glass
24.7.
DESIGN THE BUILDING WITH LESS
GLASS: Gerald Spencer, P.E. does not
wish to detract from the exterior or interior aesthetic appearance of any
facility. It would of course save energy to not provide any windows at all, and
have only insulated walls, but the morale of the personnel would be reduced, and
the personnel productivity would also be reduced.
24.8.
REVIEW OPERATIONAL PROCEDURES:
Review temperature settings,
operational hours, manpower requirements, and all other .
24.9.
REVIEW MAINTENANCE PROCEDURES:
Review expenditures, procedures, and schedules for maintenance.
24.10.
AUTOMATION:
Provide automation for resetting of space temperatures with the use of
programmable thermostats.
24.11.
HEAT RECLAIM:
We will evaluate waste heat reclaim systems addition to the existing equipment.
Auxiliary condensers added to condensing units can be used to generate domestic
hot water.
24.12.
TREES FOR WINDOW SHADING:
We will consider the addition of trees that are located to shade the windows
during the summer, to reduce the solar load on the windows.
24.13.
OTHER UTILITY COST SAVINGS:
We will discover other areas that utility cost savings are possible when we get
into this project. These items will also be evaluated.
24.14.
ECONOMIC ANALYSIS:
Gerald Spencer, P.E. provides life cycle costs of each option for the
purpose of decision making for system selection. Additional construction costs
would be sometimes serve our clients better in a savings deposit rather than
invested into more efficient energy consumption systems.
24.15.
CAPITAL EXPENDITURES:
Each proposed change to the facility will be
evaluated on a Life Cycle Cost basis to determine the economic viability of each
proposed change. Each proposed change must stand alone on it’s own economic
merit.
24.16.
OPERATION AND MAINTENANCE
CHANGES: Operations and Maintenance
changes to the facility will also be evaluated on a Life Cycle Cost basis to
determine the economic viability of each proposed change.
24.17.
ECONOMIC EVALUATION CRITERIA
EXPERIENCE: We are familiar with the
Army and NASA economic criteria and guidelines for evaluating the various
proposals for the modification of existing facilities.
24.18.
ECONOMIC EVALUATION CRITERIA:
We will work in cooperation with the
your accounting department and other departments as required to develop economic
criteria and guidelines for evaluating the various proposals for the
construction of these new facilities.
24.19.

VARIOUS
CLIMATE AND ALTITUDE DESIGNS:
Gerald Spencer is the AE of
record for successful projects in every imaginable climatic region as follows:
25.1.
High
Mountains:
Gerald
Spencer, P.E. was the Engineer of Record for several high altitude HVAC systems
including the Plutonium Production Laboratory at Rocky Flats, CO @ 8150' el.;
Buildings 147 & 149 at White Sands Missile Range @ 4000' elevation; and two
projects at the NASA White Sands Test Facility @ 4000' elevation.
25.2.
Arid
Deserts: Gerald
Spencer is the AE of record for five Department of State projects in India; for
several Corps of Engineers (CESWF and CESWA) projects at the White Sands Missile
Range, New Mexico; three Corps of Engineers (MED) projects at KAMA in Saudia
Arabia and one project at Jeddah, Saudia Arabia. White Sands New Mexico and the
NASA White Sands Test Facility are equally harsh environments where Gerald
Spencer is the Engineer of Record for multiple projects.
25.3.
Permafrost:
Gerald Spencer is
the Engineer of Record for the EXXON Unmanned Microwave Relay Station in Ignek,
Alaska. The foundation was supported on the permafrost. We poured water instead
of pouring concrete for the building foundations.
25.4.
Hurricane
Prone Areas:
All
projects along the Gulf Coast are designed to comply with the Uniform Building
Code or the South Florida/Dade County Building Code requirements for hurricane
force winds. Our hurricane structural design calculations have been reviewed and
approved by the Corps of Engineers, USAF, US Navy and NASA structural engineers.
We are current on the UBC code requirements for hurricane structural design.
25.5.
Tornado
Prone Areas:
We
are the AE for projects in the mid-West where severe weather threats occur on a
regular basis. Gerald Spencer is familiar with the alarm warning systems that
are required. The St. Louis NIMA project has an alarm horn system to advise the
building occupants of severe weather threats.
25.6.
Blowing
sand areas:
Gerald Spencer is the AE of record for five Department of State projects in
India, for several CESWF and CESWA U S Army projects at the White Sands Missile
Range, New Mexico and the NASA White Sands Test Facility.
25.7.
Freezing Environment Design:
Gerald Spencer is the AE of record for projects in Alaska, New Mexico, Colorado,
North Texas, and other freezing climates. Even Houston has a hard freeze every
ten years of so, and this requires the same design considerations that we employ
in North Texas which has below zero temperatures for at least 48 hr duration
every winter. Freezing temperatures do not need much time to cause extensive
damage. Some areas such as Amarillo, Texas has 120 °F summers and -30°F winters.
The 150°F temperature range creates some unexpected differential expansion
problems, especially with masonry veneer buildings. The Corps of Engineers
masonry construction details and specifications are probably more stringent than
any other masonry construction-design standards, but additional consideration
over and above the Corps of Engineers requirements is needed for this huge
temperature range, where masonry tends to walk off of the masonry shelves in
slab on grade construction. Moisture entrainment in exposed concrete tends to
freeze, cause concrete to splay off, and expose the reinforcing steel to the
environment. We have designed details to minimize these occurrences.
25.8.
seismic DESIGN:
Gerald Spencer is the AE or record for mechanical and electrical portions of the
seismic design retrofit projects in the central continental U.S., the offshore
Pacific coastal, and the western India where we were the AE of record. We
usually design to exceed most building code requirements. We are familiar with
the building code source documents, The National Earthquake Hazard
Reduction Program (NEHRP) Recommended Provisions for Seismic Regulations for New
Buildings and Other Structures, as well as building codes from The
Building Officials and Code Administrators (BOCA) and The Uniform Building Code
(UBC). Our seismic design procedures includes the following:
25.8.1.
Mechanical HVAC design for seismic event damage resistance.
25.8.2.

designed to comply with the Uniform Building Code and/or the South Florida/Dade
County Building Code requirements for hurricane force winds.
25.11.
HEAVY SNOW LOAD DESIGN:
Gerald Spencer, P.E. is the Engineer of
record for many projects in St. Louis, Colorado, Chicago, North Texas, New
Mexico, Virginia, Missouri, plus other areas in the Continental U. S.
25.12.
FREEZING ENVIRONMENT DESIGN:
We are the AE of record for projects in Alaska, Denver, North Texas, and other
freezing climates. Even Houston has a hard freeze every ten years of so, and
this requires the same design considerations that we employ in North Texas.
Freezing temperatures do not need much time to cause extensive damage. Some
areas such as Amarillo, Texas has 120 °F summers and -30°F winters. The 150°F
temperature design range creates some unexpected building material differential
expansion problems, especially with masonry veneer buildings. The Corps of
Engineers masonry construction details are probably more stringent than any
other details, but additional design and more stringent criteria and other
consideration is needed for the expansion caused by this huge temperature range.
Moisture entrainment in exposed concrete tends to freeze and cause concrete to
splay off and expose the reinforcing steel. We have designed details to minimize
these occurrences. We have designed details for new construction to prevent
these occurrences.
25.13.
DESERT ENVIRONMENT DESIGN:
Gerald Spencer, P.E. is the AE of record for five Department of State desert
projects in India; for one NASA-White Sands Test Facility, New Mexico project;
and for several CESWF and CESWA projects at the White Sands Missile Range, New
Mexico.
26.1.
FALL SAFETY prevention and arresting
system design: We are
the AE of record for the design and Installation of fall safety, fall prevention
and fall arresting systems at many buildings at NASA-JSC. Gerald Spencer has
attended the Approved MSA Fall Protection Installer Training Course for
certification, and is certified as in fall protection as a designer of fall
protection systems and as a Latchways® installation and maintenance mechanic for
fall protection installations. We are familiar with the requirements of
Occupational Safety and Health Administration (OSHA) Standards 1910 and 1926,
and specifically Regulations (Standards - 29 CFR) 1926.502 (b)-(e) Fall
Protection Systems Criteria and Practices. - 1926 Subpart R App G and Appendix G
to Subpart R -- § 1926.502 (b)-(e) Fall Protection Systems Criteria and
Practices. We are the AE of record for the following projects that required
Life Safety fall prevention systems be installed for the roofs of the following
buildings:
26.1.1.
BUILT-UP ROOFS:
The design of the roof
attachments to not produce water leaks during rainfall is of extreme importance
since the objects below in the test cells are very valuable. The structural
metal roof decks below the 6 inch average concrete fill will have a 2X16
pressure treated pine wood blocking add to the top of the concrete fill to
evenly spread the load. The bottom ends of new through bolts for attaching the
new roof anchors to the existing roofs metal panels for the Roof Fall Prevention
system in buildings 32, 49 and 37 are exposed and available for easy access to
apply nuts to the attachment bolts. The 12" long 3/16" bolts that are indicated
on the drawings are available with special order. The 4" lead plumbing pipe
flashings with 20" x 26" lead bases are not standard, but can be furnished by
special order from the Oatey Co. The AE considered spare lead flashings but
elected not to specify because the torn flashings can be repaired by wiping the
lead. (Or at least while the older plumbers who know how to wipe lead are still
alive). Built-up Roofing Roofs 1/8" per foot slope.
26.1.1.1.
Building 32
26.1.1.2.
Building 37
26.1.1.3.
Building 49
26.1.2.
SLOPED METAL PANEL ROOFS:
The design of the roof
attachments to pre-engineered metal building roofs should not produce water
leaks during rainfall. If there is a fall prevention system operation, the
attachment to the metal roof will probably deform and will need to be repaired
to prevent rainwater from entering the building. The metal roof decks below the
roof anchors for the Roof Fall Prevention system in buildings 920 and 260 are
not available for easy access. The Contractor would have to remove the
insulation below the roof, then replace this insulation. This operation would
require extensive and expensive scaffolding. The existing metal roof panels are
the metal building industry standard "R" panels used in most pre-engineered
metal building roof construction. Metal roofs 1:12 pitch or less
