GARFIELD COUNTY BULDING AND PLANNING
BUILDING PERMIT
109 8TH ST. GLENWOOD SPRINGS CO
May we thank you for your patience while we have coped to
the best of our ability with a difficult situation.
We are both in our late 70s and suffer from new and
aggravated health problems for many of which hydrotherapy
is the only answer. (Attachment 1) The Internal Revenuie
Service has accepted the construction and maintenenace of
the therapy facility as a necessary medical expense.
We decided we had to invest in a simple structure built to
retain heat with space and equipment for warm water
therapy. A local business owner recommended a contractor
(Roy Hunter) who had just completed a greenhouse for him
(attachment 2).
We assumed that this man was responsible and would obtain a
building permit if indeed one were required. When we called
your office to clarify the situation we were told that a
freestanding, non-commercial greenhouse required no permit
from Garfield County. (POSSIBLY this accounts for Hunter's
confusion.) Only when we added that we were installing a
therapy pool did the answer change.
By the time we discovered that a permit was required and
had not been filed, Hunter had moved to Australia and was
unresponsive.
We then set about to satisfy the County by finding a
licensed architect or engineer to validate the structure.
Our attorney at the time was unable to do this partly due
to the great building activity in the Valley. Finally we
got an architect to inspect (Haltrom Strang) and he
requested the assistance of an engineer (Robert Pattillo).
So we have ended with an architect AND an engineer.
Their recommendations (attachments 3 and 4) called for
auxiliary footings, which, in turn required a thaw -
another unavoidable delay.
Along with the requirements for changes are letters from
Mssrs Strang and Pattillo attesting their satisfactory
completion.
2
Enclosed is the building permit application (attachment 5).
As the professional drawings indicate we are dealing with a
structure built on a 20 x 50' floor with an elevation of 8-
15' (single slope roof). We enclose a check for $178.59
which we take to be the fee for examining the proposal; and
stand ready to pay an additional $274.75 at such time that
a permit is issued.

TO WHOM IT MAY CONCERN:
Grace B. and Robert H. WALKER are patients of ours.
They are in their mid -70e and suffer from a number of ailments
exacerbated by age. Their ailments Ai include arthritis,
diabetes, Meunier's disease (RHA), chronic depression (GBW).
In the treatment of ALL of these conditions regular exercise is
indicated and in some cases required. Swimming and water aerobics
are the principal therapy and, in some instances, the only
acceptable forms of treatment for both of these individuals:
ideally, short sessions 2 or 3 times daily_
This is why the Walkers invested a larges portion of their savings
in the construction of a warm -water therapy pool adiacent to
their home. The facility was due for completion in September,
1997, we are informed, but has not yet been made available. The
unavailability of water therapy has caused visible deterioration
in both patients and continues to do so.

Glenwood Springs Col
Estimate and proposal: 5-20.97
For the sum and consideration of $65,000 1 together with my partner
Matt McQuinn, we propose the following:
1, Greenhouse in the size of 20 feet by 50 feet together with a lap pool
measuring 8 feet by 40 feet by 4 feet in depth. Also including a steam shower
enclosure.
2. Building to be constructed to the idea conceived by the home owner Robert
Walker. Plan of structure to be approved at a later date and as an
amendment to this proposal. Understanding of prior conversations
understood by both parties.
3. All electrical, plumbing and filtration for proper operation of described
structure, concrete and excavation and minor revegetation of site will be
Ormed.
Other considerations:
1. Surrounding site damage: Due to the nature of the project some damage to
the surrounding area will occur. We will 'keep any damage to a minimum and
no damage other than required will be preformed. W&will re -seed and
replace any vegetation possible but no other considerations are expressed.
2. Site upon completion will be left clean and orderly and all excess materials
gill be removed in a timely manner. .
3. Billing: Billing is in four stages. Deposit of 325,000 is due before work begins.
- $1,000 is non refundable for purposes of designing and misc. expenses.
Following payments will be made at the completion of a stage, At the
completion of concrete works bill will be submitted for the sum of $20,000 for
the construction of the enclosure structure. Upon completion of the enclosure
structure a bill will be submitted for the sum of $17,000 for completion of -
interior steam room, planter box, pump room, plumbing electrical etc. Balance
2.d
l
3
of $3,000 will be paid at the end of construction when site has been approved
by Robert Walker.
4. By the nature of this estimate and fluctuating labor and materials cost the sum
of $65,000 may be exceeded but not by more than 5% ($3,250) of the total
project. This is an estimate and prices over the term of the project may vary.
Justification will be provided with any bill for over the sum of $65,000
5. Extras: During the course of this project the home owner may at any time
request the addition of any convenience he so desires. Any addition will be
agreed upon in price and a separate work order will be signed by both parties
before the change or addition is performed.
6. Time schedule: Work will begin at the earliest point possible. Due to the
demand upon sub contractors the job schedule rests with the availability of
each subcontractor and no date of completion is specified. Work will be
performed as timely and orderly as possible.
Additional considerations at time of signing contract:

Re: Walker Pool House
To Whom It May Concern:
At the request of Mr. Robert Walker, I have investigated the building containing a
therapy pool and greenhouse for Mr. and Mrs. Walker at 4006 115 rd. in the Spring
Valley area of Garfield County to determine whether it was constructed in compliance
with the 1994 Uniform Building Code. As a licensed architect and an experienced builder
in the Roaring Fork Valley, my opinion is that if the owner corrects the conditions
described below and in the engineer's report, the building would be safe, would have a
reasonable life -span, and the observable building systems and components would comply
with the code.
My opinion is based on my observation the building components that are visible and are
pertinent to the U.B.C. The engineer's report addresses structural issues, both visible
and concealed.
The issues that need to be addressed are as follows:
1. The skylight framing condition- See engineer's report.
2. The concrete foundation at the south edge of the slab and beneath the columns -
See engineer's report.
3. Frost -proofing the foundation at the south, east and west walls: South edge
of slab- Place 1 1/2" extruded polystyrene foundation insulation vertically
from the top of the slab to a depth of 14" below the finished grade,
continuous. Wrap all foundation piers and other protrusions in the foundation
to a depth of 14" below the finished grade. (See attached Foundation
Insulation Plan and "Design Guide for Frost -protected Shallow Foundations")
East and West walls- place retaining and fill in with dirt so that the
bottom of the footing is 3'-0" min. below the finished grade.
4. The existing condition of untreated wood columns resting on a concrete slab -
See engineer's report. (Placing new decay resistant columns to support the
beams renders the existing, non -complying columns redundant).
Sincerely,
Str

FPSF DESIGN PROCEDURE
APPLICATIONS/LIMITATIONS
This procedure addresses the design of frost -protected shallow foundations which use insulation
to prevent frost heave in cold climates. It is specific to slab -on -grade foundations on residential
homes but may also be used on commercial and agricultural structures. This design procedure
does not apply to buildings on permafrost, to areas with mean annual temperatures less than 32°F
(0°C), or to crawl -space construction.
The proper specification of insulation products is paramount to the success of an FPSF
application. Few insulation products are able to maintain a dry R -value in a moist, below -ground
environment over any great length of time. Insulation products specified for an FPSF must be
rated with an effective R -value that can be maintained in such an environment for the expected
_ life of the structure. Because some insulation materials resist water absorption less effectively
than others, which in turn degrades their thermal resistance (R -values), insulation material should
be specified carefully. The reader is directed to references listed in the bibliography for
additional information on this issue.
Polystyrene insulation for below -ground, frost -protection applications in the U.S. must comply
with the only available U.S. standard, ASTM C 578-92 for Rigid, Cellular Polystyrene Thermal
Insulation. Although this standard does not provide for adjustment of thermal resistance in
potentially moist, below -ground conditions, appropriate adjustment factors for EPS and XPS have
been determined based on international knowledge and experience. The reader is referred to
manufacturers for product -specific information.
This design procedure specifies insulation and foundation depths which ensure protection against
frost heave damage for all types of soils. The procedure is conservative in that it assumes a
100 -year return winter and no insulating ground vegetative or snow cover. The designer assumes
responsibility for compliance with all local building and energy codes. This document addresses
heated, unheated, and semi -heated structures as based on the expected average indoor monthly
temperature range of the building from Table 1.

:FPSF DESIGN PROCEDURE
This design guide contains two approaches: a simplified design and a detailed design. The
simplified method streamlines the design process of FPSFs for heated buildings. The procedure
is in a form suitable for adoption by the major model building codes and is intended to promote
widespread acceptance and use of the technology. In consolidating the design steps for the
simplified method, R -values for the vertical insulation were established so that the performance
} level of various conditions, including slab surface temperatures, were conservatively
accommodated. Therefore, more economical construction costs may be obtained when the
210
detailed design procedure is followed. The detailed design procedure must be used when
buildings include unheated areas such as attached garages.
SIMPLIFIED FPSF DESIGN METHOD
To use the simplified approach, the air freezing index (AFI) for the site location must be known.
An AFI contour map is provided in the Appendix to assist in establishing this value. Insulation
R -value and dimensions, and the depth of the footings are then determined from Table 2 and
Figure 4. Horizontal insulation shall be bedded firmly on smooth ground or granular base.
When foundation depths greater than 12 inches are required by Table 2, the increase in depth
may be satisfied by substituting compacted gravel, crushed rock, sand, or approved non -frost
susceptible materials.

Figure Al. United States Air -Freezing Index Contour Map
The air -freezing index method for the United States is described as cumulative degree days above and below 32°F. It is used
as a seasonal measure of the combined magnitude and duration of air temperatures below freezing. The index was computed
over a 1 2 -month period (July -June) for each of the -3,044 stations used in the above analysis. (Stuerer, 1989) Data from the
1951-80 period were tined to a Weilbull probability distribution to produce an estimate of the 100 -year return period.
Probability estimates were verified by analysis of representative, long-term weather records. (Stucrer and Crandell, 1993)
As with most contour maps. the analyzed isopleths are somewhat generalized and may depart from actual conditions.
Topographic variability, proximity to bodies of water, and urban heat effects must be considered when interpolating values
for specific locations. Dashed lines are used in areas which contain few or no stations. Micro climate effects may produce
a variability of ± 500 °F -days in the 100 -year return air freezing index estimate.
This analysis was prepared by the National Oceanic and Atmospheric Administration's National Climatic Data Center under
contract to the NAHB Research Center.(Steurer, 1989)

We understand that the structural repair work as described in our letter dated
December 13, 1999, and our two drawing sheets dated December 12 and
December 14, 1999, has been finished. Based on discussions with the owner and
builder, we believe that the construction was completed in general conformance
with our plans, details, and specifications.
Please feel free to contact me if you have any questions.
Sincerely,
Robe M. Pattillo, P.E.

Dear Robert and Grace:

As you requested, personnel of Pattillo Associates Engineers have inspected the
existing pool house building located north of your residence in the Spring Valley
area of Garfield County. The purpose of our inspection and subsequent analysis
was to determine any areas of insufficient structural construction and to
recommend repairs for the same. We understand that this evaluation is necessary
to obtain a Certificate of Occupancy from Garfield County. Our observations,
conclusions and recommendations are presented herein.
The structure is a single level building which houses a lap pool, sauna and
mechanical room. Its plan size is about 51 feet east -west by 22 feet in the north -
south direction. The floor is a slab on grade, the foundation walls are of cast -in-
place concrete with some concrete masonry unit (CMU) walls, and the roof is
constructed with post -and -beam type timber framing. The building is cut into the
south side of a small, moderately sloping hill, so that the north foundation wall
retains up to about 8 feet of soil. The grade slopes down along the east and west
walls to about the level of the slab at the southeast and southwest corners. The
south wall of the pool house is comprised of a series of sliding glass doors located
between 6x6 roof support columns. The shed roof slopes at a 1.5 to 12 pitch to
the south and is constructed of 5-1/8 x12 inch glue -laminated timbers spaced at
5I-8" to 6-8" on center. Two inch nominal thickness decking spans between the
roof beams except at four large skylight areas where the deckin is interrupted for
cellular plastic glazing. Each of the skylights is approximate' our feet wide by
sixteen feet longi and the perimeters are framed with 2x6's.
An analysis was conducted of the gravity capacity of the roof system, using a
50 psf snow load and 10 psf dead load. The glue -laminated beams were deemed
adequate for support of the full snow load, as was the decking. Problems were
discovered with the support of the skylight, however. This type of plastic glazing
must be supported about every 2 inc to prevent sagging in excess of one inch
under comparable snow loads, assuming that the material is equivalent to 5/8 inch
"Poly -Gal" polycarbonate sheeting.

Re: Walker Pool House
To Grace and Robert Walker:
At the request of Mr. Robert Walker, I have investigated the building containing a
therapy pool and greenhouse for Mr. and Mrs. Walker at 4006 115 rd. in the Spring
Valley area of Garfield County to determine whether it was constructed in compliance
with the 1994 Uniform Building Code. As a licensed architect and an experienced builder
in the Roaring Fork Valley, my opinion is that if the owner corrects the conditions
described below and in the engineer's report, the building would be safe, would have a
reasonable life -span, and the observable building systems and components would comply
with the code.
My opinion is based on my observation the building components that are visible and are
pertinent to the U.B.C. The engineer's report addresses structural issues, both visible
and concealed.
The issues that need to be addressed are as follows:
1. The skylight framing condition- See engineer's report.
2. The concrete foundation at the south edge of the slab and beneath the columns -
See engineer's report.
3. Frost -proofing the foundation at the south, east and west walls: South edge
of slab- Place 1 1/2" extruded polystyrene foundation insulation vertically
from the top of the slab to a depth of 14" below the finished grade,
continuous. Wrap all foundation piers and other protrusions in the foundation
to a depth of 14" below the finished grade. (See attached Foundation
Insulation Plan and "Design Guide for Frost -protected Shallow Foundations")
East and West walls- place retaining and fill in with dirt so that the
bottom of the footing is 3'-0" min. below the finished grade.
4. The existing condition of untreated wood columns resting on a concrete slab -
See engineer's report. (Placing new decay resistant columns to support the
beams renders the existing, non -complying columns redundant).
