OVERVIEW

EXECUTIVE SUMMARY

The Elementary Schools for USD250 are being planned for the addition of hardened spaces that will enhance the District’s capacity to provide safe places for their students during inclement weather.

George Nettels, Meadowlark, and Westside Elementary Schools will be provided with hardened spaces that will serve as (2) additional classroom spaces. These classrooms will feature a flexible and adaptive layout that provides for a variety of student configurations, allowing instruction and learning to be adjusted as needed.

Lakeside Elementary is being provided with a hardened space that will serve as the new Cafeteria for the entire facility. A new kitchen will also be provided that offers a modern and efficient layout that will enhance operations and allow for an increase in serving capacity.

The culmination of efforts of stakeholders ranging from administrators to teachers, as well as the design team, are reflected in the schematic design imagery presented in this manual.

STRUCTURAL SYSTEMS

STRUCTURAL

I. OVERVIEWThe additions to the Pittsburg elementary schools consist of the following:

A. George Nettels Elementary: Addition of two classrooms and a corridor; 1,951 square feet total. The entire addition is hardened space.

B. Meadowlark Elementary: Addition of two classrooms and a corridor; 1,904 square feet total. The entire addition is hardened space.

C. Westside Elementary: Addition of two classrooms and a corridor; 1,894 square feet total. The entire addition is hardened space.

D. Lakeside Elementary: The addition to consists of a new kitchen, a new cafeteria, and a connecting corridor. The cafeteria and the connecting corridor are hardened space and are 2,828 square feet total. The total addition is 4,874 square feet.

The additions at George Nettels, Meadowlark, and Westside will be separated from the existing buildings by approximately three feet. This separation will allow for the hardened areas to be isolated from the existing structure, and will allow for construction of the new foundations adjacent to the existing structure.

Structural design will be in accordance with the International Building Code 2012 Edition (IBC2012), as adopted and amended by the city of Pittsburg, KS. The hardened areas will also be designed in accordance with FEMA P-316 Third Edition (March 2015), and ICC 500-2014.

II. STRUCTURAL SYSTEMS DESCRIPTIONA. Structural Framing Systems: The roof framing for the hardened areas will

consist of precast concrete double tee panels spanning the short dimension of the structure. The estimated depths of the double tees are as follows: George Nettels - 28”, Meadowlark - 24”, Westside - 24”, and Lakeside - 32”. All double tee roofs will be topped with a 4” cast in place concrete slab reinforced with #4 bars at 12” o/c each way, and (3) #6 chord bars at the perimeter. The double tees will be supported by 10” precast concrete walls. The non-hardened area roofs will be framed with steel bar joist and 1.5B20 metal deck supported by steel beams and columns. The exterior walls will be constructed of reinforced concrete masonry.

B. Foundation System: Based upon the geotechnical report, the foundations for the new structures will be both continuous and isolated spread footing bearing on undisturbed soil or engineered fill. The net allowable soil bearing capacity will be as follows:

George Nettels 2,000 psf

Meadowlark 1,600 psf

Westside 2,000 psf

Lakeside 2,000 psf at continuous footings 2,500 psf at isolated footings

All footings will be cast-in-place concrete reinforced with Grade 60 reinforcing steel. Perimeter trench footings will extend to a depth of 30” below adjacent grade. The following preliminary footing sizes may be used for estimating purposes:

Continuous foundations at hardened areas:

Load bearing exterior walls - 48” wide x 26” thick footing reinforced with (2) layers of (4) #5’s long and #5’s transverse @ 12” o/c

Non-bearing exterior walls - 60” wide x 26” thick footing reinforced with (2) layers of (5) #5’s long and #5’s transverse @ 12” o/c

Continuous foundations at non-hardened areas:

Exterior walls – 18” wide x 26” thick footing reinforced w/(2) #5’s cont. top and bottom, and #4 stirrups @ 3’-0” o/c

Due to the presence of both uncontrolled fill and expansive soil, overexcavation will be required at all sites with the exception of Meadowlark. See the attached table regarding recommendations for overexcavation at the slab and the foundations.

C. Slab on Grade: All slab on grade will consist of a 4½” thick, fiber reinforced concrete slab reinforced with #4 bars at 16” o/c each way. Slabs on grade will be placed over a 15 mil. vapor barrier over 5” (minimum) of free draining granular base over a subgrade prepared as recommended by the soils engineer.

D. Lateral Systems: Resistance to wind and seismic lateral forces will be provided by precast concrete shearwalls at the hardened spaces, and by concrete masonry shearwalls at the non-hardenedspaces. Seismic loads will be based upon Site Class “C”, and Seismic Design Category “B”.

SOILS REPORT SUMMARY 8/15/2017

STRUCTURAL

LOCATION EXISTING CONDITIONS RECOMMENDATION

Meadowlark Elementary Classroom Addition

No fill present

Low plasticity soilGrub and prepare the site per the soils report. This site will require minimal site work.

Westside Elementary Classroom Addition

Fill from 0 to 5.5 foot in depth

High plasticity soil to a depth of 8.5 foot below grade

Remove 24” of soil minimum over the entire site plus 5’-0” each side beyond the building footprint. Replace with a low volume change fill placed and compacted per the soils report.

Where no fill is present, excavate below all footings 2’-0” (ELEV= 95’-0”) and backfill to bottom of footing elevation (ELEV= 97’-0”) with lean concrete. The excavation should be 6” wider than the footing dimension.

Where 2’-6” or less fill is present, excavate to ELEV= 95’-0” and backfill to bottom of footing elevation (ELEV= 97’-0”) with lean concrete. The excavation should be 6” wider than the footing dimension.

Where fill is present ranging in depth from 3’-0” to 5’-0”, excavate to ELEV= 94’-6” and backfill to bottom of footing elevation (ELEV= 97’-0”) with lean concrete. The excavation should be 6” wider than the footing dimension.

Where fill to depths greater than 5’-0” are present, excavate completely through the fill to the undisturbed soil beneath. Backfill to bottom of footing elevation (ELEV= 97’-0”) with lean concrete. The excavation should be 6” wider than the footing dimension. This should only occur at Westside Elementary, and only at a small area.

For excavations adjacent to the existing footing, the soil may be excavated below the existing footing by keeping away from the existing footing a horizontal distance of 6” for each 12” of excavation below the footing. (See table below).

DEPTH OF FILL “H”

0’ to 2’-6” 1’-6”

3’-0” to 5’-0” 1’-9”

5’-6” 2’-0”

6’-0” 2’-3”

As an alternative to maintaining the horizontal distance from the existing footing, the soil may be excavated vertically at the face of the existing footing to a depth of 24” below the footing. This excavation may be made in 8’-0” lengths provided the lean concrete is placed within 24 hours.

Regarding the 6” over-excavation; at the contractors discretion, the footing may be cast 6” wider to match the width of the lean concrete. This will result in approximately one additional yard of concrete for every 25’ of footing. There will be no increase in steel. A second option would be to line both sides of the excavation with 3” of insulation.

George Nettels Elementary Classroom Addition


High plasticity soil ranging in depth from 12 to 18 foot below grade

Lakeside Elementary Classroom Addition


High plasticity soil ranging in depth from 8 to 11 foot below grade
