project introduction
Presented in this booklet is the Schematic Design Phase concept representing a proposal
for a series of related improvement projects focused in the general area of the existing
Marshalltown CSD’s High School Round House in Marshalltown, Iowa.
This proposal is a result of an extensive master planning effort which reasonably evaluated
all potential programmatic and functional user group desires related to physical education,
competitive athletic, recreational and support functions for the existing Round House area of
use… now and into the foreseeable future.
We are excited that this proposal adds and improves so many functional, educational and
competitive Iowa High School needs. As well, we believe the proposed improvements pay
rightful respect to the existing history and powerful image of the existing Round House.
We have paid particular attention to the style and scale of the new additions with the goal
of “highlighting” and “featuring” the major attributes of the Round House. We strongly
believe the proposed building additions will communicate your school district’s quest to stay
competitive and current with a prideful balance that highlights your historical success and
community contribution.
During this initial design phase, our team has worked to establish a programmatic area
summary, floor plans, room sizes, and critical placement walls for the structural, mechanical,
plumbing and electrical infrastructure concepts. The design was first developed in order to
determine the magnitude of funding need and secondly developed as proof of concept. The
Schematic Design proposal now shows projects (A-C.1) within the framework of current
budget allocation of $9.10 million dollars (y2013 estimates). We will continue to test the
design as it develops against the project budget and the probability of cost in the construction
market in the Marshalltown area.
Projects selected to move into Design Development include:

New Auxiliary Gymnasium with support spaces
New Wrestling Room with support spaces
project introduction
Although desired for the future, no site improvements are proposed “east of the west curb of
the existing School Drive”. During the next phase of our work, the design team will evaluate
Bus drop-off lane improvements on the south side of the existing Round House site area
within the project budgets that accompany this proposal. It is strongly desired that the project
will include a safer drop-off and pick-up sequence for visiting team buses and related
parking and pick up conflicts.
The building additions and site improvements will be designed to meet current ADA standards.
The project is not seeking LEED Certification, but will be planned using sustainable design
principles and practices.
Our team is committed to providing the Marshalltown Community School District with a series
of improvement projects that are a balance of programmatic, aesthetic, and budget conscious
efficiency. We believe this design proposal is a competitive and responsive design solution that
meets the expectations of program, budget, schedule, site and the dreams of those who will
use it for many years to come.
As we move forward with your authorization, into the “Design Development Phase,” many
more details will be finalized and documents will be readied for the project to be bid by
contractors in the late summer of 2013.

architectural narrative
Our first choice for the dominant exterior finish material on the new additions is a product
called “prairie stone” which is a masonry module product that has the durability and maintenance characteristics of brick plus the larger sized dimensional characteristics of architectural precast panels. This finish product for the building’s exterior walls will be backed up
by a construct system of concrete masonry units (CMU) or structural metal studs, rigid cavity
insulation, wall cavity sheathing and appropriate flashing systems.
New entrances and vestibules will be constructed with structural steel and energy efficient
window/curtain-wall and store front glazing systems. We will likely use some metal panel to
highlight entrance canopy and large scale “super graphic” symbols (currently shown as large
“flying M’s” (a recognized Marshalltown CSD brand).
The new building addition’s roof systems will be primarily membrane on rigid insulation on
metal roof deck on metal bar joists.
A majority of the interior walls will be painted or burnished CMU in high traffic/abuse areas
with metal stud wall framing with painted abuse resistant gypsum board wall finish in nonabusive areas.

landscape architectural
The Marshalltown H.S. Roundhouse Renovation site is approximately 3.5 acres.
The site design overview consists of the roundhouse and associated building expansion, a
reconfigured vehicular drop -off, pedestrian access to the northeast and southeast of the
building and site landscape.
The roundhouse will include a phase one building renovation to the existing facility and
a future expansion to the north. Pedestrian access will be provided to the southeast and
northeast of the building renovation with delivery and service access for events included in
the northeast access plaza
Vehicular access consists of one drop-off curb side lane directly south of the roundhouse.
Pedestrian access will be provided with entry plazas extending from the southeast and
northeast of the building, extending to the adjacent intersections along School Drive.
Site plantings include seed for open green space and trees and shrubs as required by City
will be included in the project. Native grasses and wildflower seeding is proposed for storm
water detention.

civil narrative
Site Work, Utilities, and Demolition
●
Demolition: The existing weight room on the south side of the Roundhouse will
be removed as part of this project. Portions of the sidewalks on the north and south side
of the Roundhouse will be removed to accommodate the addition and the existing sidewalk
on the east side of the Roundhouse will completely removed and replaced as shown in the
landscape renderings. Minor removal and replacement will occur within Bobcat Boulevard to
accommodate the new landscape plan.
●
Vehicular Access: The existing drives on the north, south, and east sides of the
building will have minor removal and replacement to accommodate the improvements and
utility relocations that will be required. A new driveway will be placed on the north side of
the Roundhouse for access to the new overhead door.
●
Utilities: The Phase I addition will require a gas service and a large 24” storm
sewer on the south side of the Roundhouse to be relocated to accommodate the new
expansion. The existing 8” sanitary sewer service will remain in place and may be used to
collect a new service from the auxiliary locker rooms on the south side of the building.
●
Stormwater Management Post Construction: The City of Marshalltown requires
that new construction incorporate stormwater management practices into their designs to
manage increased runoff from sites that add impervious area (roofs and pavement). This
requirement is for volume and treatment control. The current ordinance requires that
stormwater peak flows after construction meet the same peak flows that exist on site today.
The use of pervious pavers in the landscape design will assist in capturing runoff from some
of the sidewalk areas and will provide storage space below the walkways for increased
runoff storage. The use of native plantings will reduce runoff due to their deep root structure
and will also serve as a storm water treatment facility for the quality control that is required.
●
Stormwater Management During Construction: The amount of area being
disturbed for this project is less than an acre and therefore, does not require an Iowa DNR
permit. However, the City of Marshalltown requires a Minor Erosion Control Permit for any
activity that disturbs 1/4 of an acre or more. A complete Storm Water Pollution Prevention
Plan (SWPPP) will not be required, but the owner will be required to install temporary Best
Management Practices (BMPs) to control erosion from leaving the site. BMPS such as
silt fence, compost filled socks, temporary sediment basins, straw bales, potential street
sweeping, and contained concrete washout areas will be required during construction. The
contractor will inspect these BMPs within 24 hours of every ½” of rain and a minimum of
every 7 days as part of their contract.

Project Description
The project consists of a renovation and addition to the existing Roundhouse at Marshalltown High
School in Marshalltown, Iowa that was originally constructed in 1963. The renovation will consist
of a new roof, mechanical upgrades, electrical upgrades, new sprinkler system, renovated locker
room, and renovated support spaces. The additions will include a new two-story locker room
and weight room space. There will also be a new one story addition that will contain new entries,
athletic administration offices, and a hall of pride. In a second phase a construction a new auxiliary
gymnasium and wrestling room will be constructed. Foundations (Addition)
A geotechnical engineering report was prepared by Terracon Consultants, Inc. in September of 2010
for a proposed roundhouse addition. The existing site contains a typical soil profile of 8 to 14 feet
of fill material that does not appear to have been placed with moisture or density control. The fill
material contains, in part, moderately expansive lean to fat clays. The fill rests upon a layer of loess
soils (lean clays) that occurs at a depth of 17 to 24 feet. The loess soils bear upon a layer of native
glacial till soils.
As a result of the material type and the uncontrolled placement of the fill materials there is a
significant risk of larger than acceptable differential and total settlements of the floor slabs. There
is also a significant risk of damage to the floor slabs due to the moderately expansive nature of the
fill materials. Complete removal and replacement of the fill materials is the least risk solution to
the problem, however the cost and constructability of this option does not result in this being a very
feasible solution. There is however two other solutions that appears to be feasible for this project.
The first of these solutions is to install a ground improvement system such as rammed aggregate
piers, stone columns, etc. This solution would be the more costly of the two, but would provide the
least amount of risk to the Owner. The design of the ground improvement system would also need to
accommodate the potential for the expansive nature of the existing fill materials.
The second option for remedying the poor fill materials would be to remove at least two feet of the
existing fill materials and replace it with granular structural fill material. This option would be the
least expensive, but the Owner would need to accept a greater level of risk for larger than tolerable
floor settlements. If this solution was chosen, no additional work would need to be completed to
accommodate the potential for the expansive nature of the fill materials.
.

structural systems
The on grade floor slabs for the project will consist of a 5” thick reinforced concrete slab-on-grade
that is placed over a minimum 15 mil vapor retarder.
There are two options for how the building structure will typically will be supported. The first
foundation option is to use typical spread footings that bear on soils that have been improved through
a ground improvement system similar to what was described earlier for the floor slabs. The spread
footings would be constructed using reinforced concrete.
The second option for the building foundations would be to use a deep foundation system that extends
down to the native glacial till soils. This deep foundation system would consist of either drilled
concrete shafts, similar to the existing building foundations, or augered cast-in-place concrete piles.
Grade beams and pile caps would be constructed to support the building structure and transfer the
loads to the deep foundation elements. There is the potential for ground water at the depths the deep
foundations would be constructed, so the drilled shaft option would require temporary steel casings.
A portion of the new additions will be located below grade, so they will require the use of basement
walls. These walls will consist of 12” concrete walls with conventional mild reinforcing.
Cost, constructability, and the level of risk the Owner is willing to accept will determine what
foundation system and floor slab support is used in the final design.
Floor Framing System (Addition)
The only elevated floor slab will occur in the two-story locker room and weight room addition on
the southwest side of the existing roundhouse. The floor system in this space will consist of precast
concrete hollow-core floor slabs with a reinforced concrete topping. These floor slabs will span to
either load-bearing concrete masonry walls or structural steel beams and columns. This floor system
provides the strength and durability required to support the weight training activities planned. The
mass of the floor should also help to dampen any vibrations that might occur from the weight training
activities.
Wall Framing System (Addition)
The wall framing system for the additions will most likely consist of a combination of light gage metal
stud walls that span from the foundations to the roof. This system will be located in areas that are
low traffic and do not have the potential for damage from activities inside the adjacent spaces. In
the areas where a more durable wall surface is desired, such as the locker rooms, wrestling rooms,
weight rooms, and the auxiliary gymnasium a reinforced concrete masonry wall will be used.
16
structural systems
Roof Framing System (Addition)
The roof framing system for the additions will be comprised of a steel structure. This structure
will consist of 1.5” type B metal roof decking spanning to steel bar joists spaced at 6’0” on center
maximum spacing. The steel bar joists will be supported by non-composite structural steel beams
spanning to structural steel columns or load-bearing concrete masonry walls. There areas directly
adjacent to the building would contain joist spacing closer than listed above to account for the drifted
snow potential that will exist when the new addition abuts the existing taller roundhouse. It is
anticipated that over the Auxiliary Gym that longspan steel bar joists will need to be used to allow for
a longer clear span over this space.
Lateral Load Resisting System (Addition)
The lateral load resisting system for the building will be a combination of steel braced frames and/or
reinforced concrete masonry shear walls.
Structural Renovations
The structural renovations inside the existing roundhouse will be fairly limited in nature. The existing
structural system will remain essentially as is. There will be extensive remodeling of non-load
bearing partition walls inside the existing spaces. Typical steel lintels or reinforced concrete masonry
lintels will be provided in these non load-bearing walls as required. The most extensive renovation
scope of work will be the removal and support of the existing exterior precast concrete wall panels in
certain areas. These panels are being removed to provide new entrances and/or circulation into the
existing space.
CODE COMPLIANCE STATEMENT-STRUCTURAL
The building is anticipated to be designed and constructed to the requirements of International
Building Code 2009 and The University of Iowa Design Standards and Procedures.
The building will be designed to resist live, snow, wind and seismic loads per IBC 2009 and ASCE
7-05 requirements.
Wind loads are expected to govern the lateral load design and will be based on ASCE-7-05
requirements. These are:

SYSTEM DESCRIPTION
1. A life cycle cost analysis is required by State law for new and renovated facilities if the construction cost exceeds fifty percent of the value of the facility. RDG believes the
renovation will not be in excess of this value and a life cycle cost analysis will not be required. However, we believe a economic analysis should be completed to ensure
we have properly investigated the available options. We recommend the analysis look
at three mechanical systems and three domestic hot water heating systems.
