EXECUTIVE SUMMARY

Introduction T.F. International is looking forward to providing professional engineering services to the San

Diego International Airport for the design and construction of the new Administration Building.

T.F. International prides itself in offering the most cost-effective and sustainable solutions for

public infrastructure improvements and land development. The new San Diego Airport

Administration Building will be located on Airport terminal Road and McCain Road. This

project will include the redesign and resurfacing of the existing Terminal 2 parking lot, located

next to the new facility. The reconfiguration of the parking lot will allow access to employee

parking and account for the increased volume of motor vehicles. The new Administration

Building will be a key feature for the employees of the San Diego Airport and the people of San

Diego.

Background The San Diego Airport Administration Building will be used for all administration activities and

corporate endeavors. The San Diego Airport uses renewable resources to achieve their

environmental objectives, therefore, T.F. International plans on creating LEED Gold certified

building. The current area where the new Administration building will be located does not have

high traffic flow, but once construction starts and the Administration is built, the traffic flow will

greatly increase. Because of this T.F. International will create a new traffic plan in order to create

a controlled traffic environment. Currently, the area including the Airport Terminal Rd being a

one way street, bringing construction supplies through this one way road would be difficult.

McCain Road comes to an abrupt stop ten feet after the entrance of the proposed Administration

Building site entrance. One entrance to the terminal two is to the left of the proposed building,

this is where truck loads for the airports arrive, this will affect traffic conditions. Traffic

conditions are limited by Airport Terminal Road being a one way street and McCain Road being

a busy and barricade road. Parking lot relocation will improve traffic conditions but will affect

pedestrians accessibility to onsite parking.

Purpose and Objective The new SDIA Administration Building has been assigned to T.F. International to work on Site

development. T.F. International will construct the New Administration building which will be 6

stories building, maximum 95 feet high, and 150000 SF. T.F. International will provide detailed

documents, drawing, and plans about the work breakdown structure of the project.

Transportation study ​will analyze the current traffic studies and the future projection traffic

studies to determine the project impact on traffic. Based on traffic studies, T.F. International will

determine the need for the traffic signal or intersection control improvement at the intersection of

McCain Road and Airport Terminal Road. Structural study will provide structural systems

recommendations, and it will provide structural analysis of the SDIA Administration Building

for the purposes of construction cost and construction analysis. Stormwater study will conduct

drainage studies and SWQMP for the project, and it will provide development recommendations

for stormwater reuse and water quality ​BIM​'s/ ​LID's. Water and Sewer study will conduct water

and Sewer studies and provide calculations, design, and analyze the impacts of the project with

recommendations of offsite improvements. Geotechnical study will conduct studies to determine

the soil characteristics and behavior in the region. T.F. will analyze the data to study the study

the soil performance and if soil mitigation is needed for the project. Also, T.F. International will

provide recommendations for foundation design by analyzing thoroughly the drainage, pressure,

and Soil strength. Construction analysis will provide construction detailed phasing, site logistics,

and Project scheduling. T.F. International will provide project construction detailed cost

estimation that includes labor cost and materials cost. The site logistic and construction Access

will include Access plans, Laydown, and Truck Haul.

Findings

● Geotechnical

The Boring logs and Cone Penetration Tests (CPT) provided by Allied Geotechnical

Engineers, Inc. gave us data and information of the soil from an area located

approximately 200 feet from the new SDIA administration building. From this data

provided, we were able to classify the soil as silty sand.

● Water

After conducting a water study for the new administration building T.F. International

engineers have found that the new building will have a peak hour water demand of 83

gallons per minute and the minimum fire flow required for the building is 4,260 gallons

per minute.

● Sewer A peak wet weather flow or design flow of 167,216 gallons per day is expected from the

building once it is fully operational. The main sewer pipe line ​running along McCain Rd.

is a 8” Vitrified Clay pipe and the sewer main running along Spruance Rd. is a 18”

Vitrified Clay pipe.

● Storm Water

Current Rock Swale Infiltration basin is surrounding the building. Basin must be able to

manage 2.38 cfs for a 100 year-storm. New entrance will affect current basin, new basin

or minimization of current basin is needed. Basin will filter storm water before it is

released out into the San Diego Bay.

● Structural

The best material in terms of strength and minimal costs for the necessities of this project

is reinforced concrete. The surrounding buildings at the airport are not as tall as the new

administration building is designed to be but after getting approval from the airport, the

height will not interfere with the airport towers.

● Transportation:

T.F. International found that The Administration Building will be occupied with

approximately 550 people daily. T.F. International has calculated a proposed Level of

Service for the interaction which come up to be LOS C. T.F. International has found that

Airport employee, Airport visitors, and contractors will park at Terminal 2 parking lot.

Recommendations

● Geotechnical Regarding the foundation of the building, Geotechnical Engineers at T.F. International

recommend using ​embedded shallow foundation​. This specific foundation type meets

California’s seismic requirements and satisfies the factor of safety.

● Water

T.F. International engineers have analyzed different pipe diameters that can carry the

peak hour flow meeting maximum velocities required by the 2016 California Plumbing

Code and pressure criteria established by the City of San Diego Water Department. We

believe that a 2 ½ in diameter PVC pipe since minimum pressure would be met even

when there are fluctuations in pressure of +/- 10 psi.

● Sewer

After conducting a sewer study for the proposed building T.F. International has

determined that the installation of a standard 10 in PVC sewer pipe at a minimum 2

percent slope would be a good fit for this project. As shown in the sewer study, such pipe

would be able to handle the expected peak wet weather flow from the proposed building

and meets all the regulations established by the Sewer Design Guide for the city of San

Diego Public Utilities Department.

● Storm Water

T.F international recommends current Rock Infiltration Swale to remain in place,

shortening existing length of 160 feet to 130 feet in order to accommodate proposed exit.

Rock Infiltration Swale ability to manage stormwater will not be affected by minimizing

dimensions.

● Structural

The structural engineers at T.F. International have concluded that reinforced concrete

provides the most support while limiting the costs of the object. We recommend the

concrete to be poured in place for the structural shell of the building. The reinforcement

in cast in place concrete is much stronger the precast concrete so to ensure a safe and

sturdy building we recommend cast in place. The Monolithic Pour Construction Method

is also recommended and will be done by splitting the building’s perimeter into four

sections and pouring floor by floor.

● Transportation

T.F. International recommends to allocate a section of Terminal 2 parking for the

Administration Building and adding two-arm gates as an exit for the parking lot on the

Airport Road. T.F. recommends converting the Westbound on Airport Road from two

lanes to a single lane with proper striping, adding flashing Stop Sign on the Westbound

lane. This recommendation will add additional safety for the increase pedestrian crossing

along the Westbound going to and from the Administration Building to the parking lot.

Conclusion T.F. International is eager to provide the San Diego International Airport with the most

sustainable and cost efficient design that will not only meet the high expectations, but exceed

them. T.F. International is confident in their work for the Administration Building and all of the

engineering elements that come with it. This project will include the redesign and resurfacing of

the existing Terminal 2 parking lot, located next to the new facility. The reconfiguration of the

parking lot will allow access to employee parking and account for the increased volume of motor

vehicles. The new Administration Building will be a key feature for the employees of the San

Diego Airport and the people of San Diego. Through each of our studies, we have shown

comprehensive and detailed reports that highlight the site development for the SDIA

Administration building. We at T.F. International have tackled this project and feel confident that

we have addressed all concerns and provide industry leading service.
