technical writing report about our group project, but the report will be just on my part which is the phase 6 of the project. Everything will be attached so you will have an idea of the project. Please do you best and please do a refrence citition for the (ASCE7-10 and IBC2012) and anything you will used that needed to be cited. Also, do tables for the materials quantites and prices and instulation costs.As I mention eveything will be attched, fistr I will attach five files here and then when you acceplt the work I can attach the rest.Notes, for the column calcultion try do your best our choosen section is W12x14.

Phase 3: Parking Lot
No parking exists
Not attractive to drive through the mud/dirt with family
? Implement an ADA compliant asphalt parking lot with overland
drainage directed to the stream.

Phase 5: Drainage
South side of park holds water
? Doesnt make it to the stream/culvert
Stream has some erosion issues
With new implementations, we want to account for the new
? Q25 = 11.84 cfs (Pre-Development)
? Q25 = 14.21 cfs (Post-Development)

Phase 6: Utility Plan
No public utilities currently
? Water and sewer running along Stewart Road, so connections are
? Existing Temp-restroom, but Parks and Rec Department want it removed
? Highly inconvenient to have to leave the park to use the restroom
In-house design of a public restroom and water fountain

Codes and Resources
Codes/Standards to be followed:
All applicable City of Mobile Ordinances

City of Mobile: Requirements for Building in a Flood Zone
? International Building Code (IBC2012)
? ASCE 7-10
? AISC Manual
Other Resources to be used:

? Previous park/walkway/stream designs located in the City of Mobile
Baldwin Sand and Gravel
Roof materials, metal roof instead of rubber membrane because of the live span of the metal that will
live longer. Steel 60 yrs. live span, and 30 yrs. live span for the rubber.
From the ASCE7-10(American society of civil engineering), The utilities building will be under risk
category 1 using the LRFD method.
Also using the ASCE7-10 and the IBC-2012:
Unit weight of the metal roof, 14-gauge metal roof has unit weight of 3.13 psf, and we accounted for
10% for the hardware weight therefore approximately 4 psf is the Dead Load for the building.
The roof live load is 20 psf for an ordinary monoslope roof.
Since the elevation of the park topo map is 10 ft, there is no need to include flood design.
Using the directional method, the building at exposure B and the minimum wind speed city of Mobile is
150 mph from the IBC-2012 (international building code). So, the qz=28 psf, and G= 0.85. The slope is
6.9o. Therefore, we calculated wind roof load of 29 psf, and wind wall load of 20 psf.
The intensity of 100 year/hr. rainfall is 4.5 in/hr. No ponding instability because of the roof slope exceed
1.19o. Hydraulic head of 1 in, and static head of 3 in. So, we got rain load of 20.8 psf.
Using the LRFD method we calculated six combinations loads, 8.4 psf, 17.6 psf, 54.98 psf, 46.6 psf, and
34.4 psf. And we choose the 54.98=55 psf as it the largest combination load.
Is going to be steel members consists of two beams and four girders and four columns. The team choose
the steel structure instead of the concrete walls because of the live span and the cost effective of the
steel than the reinforced concrete, and due to the fact that we required short space and cost effective
for the building.
At= 46.75 ft2
At KLL= 93.5 ft2 < 400 ft2 Therefore, no reduction needed. LRFD, factored load Pu= 55 psf Wu= 151.25 lb/ft. Zx= 1.5 in3 So, from the Zx table we choose W8x10 beam. ... Purchase answer to see full attachment
