Dear Board Members:

COUNTY OF SAN JOAQUIN DEPARTMENT OF AVIATION

Harry S. Mavrogenes Airport Director

APPROVAL OF PLANS AND SPECIFICATIONS TO REHABILITATE RUNWAY AND TAXIWAY LIGHTING AND SIGNAGEAND SETTING A BID OPENING DATE OF JULY 30, 2014

AT 2:00 P.M. AND APRROVAL OF APPLICATION FOR FEDERAL ASSISTANCE

RECOMMENDATION:

It is recommended that the Board of Supervisors adopt a Resolution:

1. Approving Plans and Specifications prepared by Reinard W. Brand1ey, Consulting Airport Engineer, to Rehabilitate Runway and Taxiway Lighting and Signage (Project) at Stockton Metropolitan Airport;

2. Directing the Department of Aviation to advertise the Project for bid, using the specific Federal Aviation Administration (FAA) language set forth in the Notice Inviting Bids included in the Specifications;

3. Setting the bid opening date of July 30,2014 at 2:00 p.m. in the Stockton Metropolitan Airport Conference Room. Said bids are to be opened by Department of Aviation staff; and

4. Authorizing the Airport Director to sign the Application for Federal Assistance, Notice Inviting Bids, and any documents in order to expedite the Project.

REASONS FOR RECOMMENDATION:

A Federal Aviation Administration (FAA) Application for Federal Assistance was submitted to the FAA to Rehabilitate Runway and Taxiway Lighting and Signage in the Plans and Specifications herein submitted. Stockton Metropolitan Airport has experienced significant problems over the past few years with the runway and taxiway edge light system. The problems have manifest themselves in failure of components of the regulator providing power to the runway circuit. A series of tests and detailed field observations were conducted in the fall of 2013 for the purpose of determining the problem with the airfield lighting systems and suggested measures for correction. This is currently the highest safety priority for the Airport and will improve safety by enhancing the extent to which the County meets Airport Design Standards.

These tests showed a resistance to ground of zero for all four runway circuit segments. It is, therefore, concluded that the cabling and transformers require replacement to increase the resistance to ground of all circuits and improve the performance of these circuits.

5000 SOUTH AIRPORT WAY «I TERMfNAL BUILDING, SUITE 202 .. STOCKTON, G4UFORNIA 95206-3996 • PHONE; (209) 468·4700 " FAX: (209) 468·4730

The results of these tests and observations indicate the following corrective actions should be taken to reinstate the integrity ofthe system and protect the system from future deterioration. Recommended design features include the following:

• Runway Lighting System - Updated including new high-intensity quartz edge lights, new transformers, and new cable, and all duct and pull box systems will be cleaned out.

• Taxiway Edge Lights - New LED lights and transformers, new cabling, and clean out and rehabilitate all duct and pull box systems.

• Signs - Use existing signs with new transformers and revise distance remaining sign legends to represent existing conditions.

• Update all wiring and controls in the vault and Air Traffic Control Tower.

The Base Bid will include utilizing the existing L-821 control panels in the vault and FAA Control Tower to control all circuits. As an additive alternate, a computer-activated control system is proposed in the vault and Tower for all systems. This will include the addition of new fiber optic control cables. All of these items are eligible for Federal funding.

During the test program, it was discovered that there was significant water in the light and duct system, particularly at the low west end ofthe runway. This is caused by inflow throughout the system and there is no way of discharging it as the entire system is placed in an impervious highly plastic clay soil. This moisture has a detrimental effect on the resistance to ground of the systems. It is proposed in this project to intercept the duct and light base system periodically, particularly in the low areas, with a drainline that is carried to the main drainage systems on the AirpOlt. This will allow any water that gets into the system to immediately be discharged and maintain a drier condition. It will also be important to raise the transformers and cable above the bottom of the light base.

The bid document has been prepared with a base bid and one additive alternate to enable the County to select the portions of work that can be accomplished with available FAA and local funding.

On January 14, 2014, the Board of Supervisors approved the Project which FAA deemed eligible for federal grant funding covering 90 percent of the Project cost. It is, therefore, requested that the Board of Supervisors approve the Plans and Specifications, and set the bid opening date of July 30, 2014 at 2:00 p.m.in the Stockton Metropolitan Airport Department of Aviation Conference Room.

FISCAL IMPACT:

The cost to the Department of Aviation for engineering and architectural services (including the Engineer's Design report), project advertisement, and printing and distribution of the documents, is approximately $52,000. FAA grant funding (AIP-33) will provide for 90 percent of the cost. The remaining share, approximately $5,200, will be paid for with Airport funds.

The amount of FAA funding for the runway and taxiway lighting project will be based upon the successful construction bid offer to be received at the bid opening. The Engineer's Estimate for construction is $936,000 for the Base Bid and an additional $100,000 for Alternate No. I. There will be additional costs for project management, including testing and inspection, which is

estimated to be $80,000, and is also eligible for FAA funding.

The FAA will pay for 90 percent of the total cost and the County will be required to match the remaining 10 percent, which will be funded through the Airport Passenger Facility Charge program. The estimated projects costs are as follows:

AlP NO. 3-06-0250-33

ENGINEER'S REPORT

I. INTRODUCTION

The County of San Joaquin Department of Aviation, with Federal assistance from the

Federal Aviation Administration under the Airport Improvement Program (AlP), proposes the

rehabilitation of the Runway and Taxiway Lighting and Signage systems at Stockton

Metropolitan Airport, Stockton, California.

This work is being funded under AlP Project No. 3-06-0250-33. This report describes

the basis of design for this work.

II. LAYOUT AND SCOPE

The basic layout of the project is shown on Plate No.1 entitled, Construction Safety and

Phasing Plan.

Stockton Metropolitan Airport has experienced significant problems over the past few

years with the runway and taxiway edge lighting system. The problems have manifest

themselves in failure of components of the regulator providing power to the runway circuit. A

Stockton Melropolilan Ai/pol" AlP No. 3*06*0250·33

Engineer's Repor' JUlie 24, 20/4

series of tests and detailed field observations were conducted in the fall of 2013 for the purpose

of determining the problem with the airfield lighting systems and suggested remedial measures

to make corrections. It was found that the resistance to ground of all seven circuits was zero,

indicating deficiencies in the cable and transformers. The lights on the runways and taxiways

are old quartz lights and need to be replaced.

The results of these tests and observations indicate the following corrective actions

should be taken to reinstate the integrity of the system and protect the system from future

deterioration. A summary of the recommended rehabilitation to the runway and taxiway lighting

system includes the following:

1. On all seven circuits (one runway circuit, five taxiway circuits, one PAPI circuit), all existing cable will be removed from the electrical vault throughout the circuit and replaced with new FAA. approved 5 KV cable sized to accommodate the loads. All ducts will be flushed, swabbed, and mandreled and new cable installed.

2. All isolation transformers will be removed and replaced.

3. All of the duct systems will be drained such that any surface water that gets into the system is quickly removed.

4. New light base gaskets will be provided and installed on all light bases.

5. Existing runway light fixtures will be removed and replaced with new quartz light fixtures and transformers. LED runway lights are not eligible for Federal funding at this time.

6. Existing taxiway light fixtures will be removed and replaced with new LED light fixtures and transformers.

7. The distance remaining sign system will be reconfigured to conform to FAA. standards and new transformers will be installed in all remaining signs.

8. All duct systems will be drained such that any surface water that gets into the system can be quickly removed by installing new HOPE pipe from the light cans to existing inlet structures.

9. Existing L821 control panels will be updated in the Air Traffic Control Tower and in the electrical vault in the Base Bid or, if Additive Alternate No.1 is accepted, a new computer-controlled Airfield Lighting Control and Monitoring System (ALCMS) will be furnished and installed.

Slockton Metropolilan Ai/pol" AlP No. 3-06-0250-33

Engineer's Report JUlie 24, 2014

III. DRAINAGE

During the testing program, it was discovered that there was significant water in the light

and duct system, particularly at the low west end of the runway. It is proposed in this project to

intercept the duct and light base system periodically, particularly in the low areas, with a 3-inch

high-density polyethylene pipe drainline that is carried to the main drainage systems on the

airport. This will allow any water that gets into the system to immediately be discharged and

maintain a drier condition.

It will also be important to raise the transformers and cable above the bottom of the light

base. This will be accomplished by placing a brick under each transformer in each light base.

IV. ELECTRICAL SYSTEMS

The current electrical system at the airport consists of one runway circuit, five taxiway

circuits, and one PAPI circuit. The testing of the airfield lighting circuits showed that the circuits

have very low resistance to ground and that all runway, taxiway, and PAPI circuits show very

low resistance to ground. The cabling system and in-line transformers on each circuit need to

be replaced with new equipment.

All existing cable and transformers will be removed and replaced with new airfield

lighting cable and transformers in the existing ducts. This project will also include the removal of

any damaged existing electrical duct lines and replacing them with new duct lines. After the

existing cable in existing duct lines has been removed, the duct line will be flushed and swabbed to

clean out all soil and debris and then a properly sized mandrel pulled through the duct to assure

that it is clear. If the mandrel cannot be pulled through the duct line, the location of the defect in the

duct line will be identified and the existing damaged section of the duct removed and new duct

installed.

FAA. approved plug-in connector kits will be used for all splices. All field splices made

with connector kits will be wrapped with electrical tape and then a heat shrink kit placed over the

Stockton Metropolitan Ai/port AlP No. 3-06-0250-33

3

Engineer's Report June 24. 2014

top of the tape and splice heated with a torch so as to protect the kit by providing a watertight

joint.

Each individual duct will be mandreled. In all areas where the mandrel operation shows a

damaged or plugged duct, the Contractor will unplug the duct by flushing, but those areas that

cannot accept the mandrel will be removed and replaced with new sections of the same size duct

properly spliced to the sections of existing duct left in place. All existing and new ducts will be

swabbed out and cleaned immediately prior to pulling cable.

All isolation transformers in all runway and taxiway edge lights and in all airfield

guidance signs will be removed and replaced with new isolation transformers of the sizes

required for the lights and signs.

V. VAULT AND CONTROL TOWER

There is currently one L821 lighting control panel located in the electrical vault and one

L821 lighting control panel located in the Air Traffic Control Tower. The Base Bid of this

contract consists of rewiring the controls and equipment in the vault and rewiring the controls in

the Air Traffic Control Tower to place all controls in operating condition. This item also includes

the rewiring of the existing L821 control panels - one in the vault and one in the Air Traffic

Control Tower.

If Additive Alternate No. 1 is not accepted, the following general conditions and

requirements will apply for the lighting control system:

• The existing L821 control panels in the vault and in the Control Tower will remain in use to control all critical circuits.

• The existing control cable between the vault and the Control Tower will remain in place and used in the system.

• The existing TowerNault control switch in the Control Tower and vault will remain in place and be used to transfer control between the Tower and Vault.

• Controls will be rewired in the Tower and in the vault to provide control of the revised circuitry and equipment.

• Power supply and distribution systems in the vault will be revised as necessary to accommodate new system configuration.

Stockton Metropolitan Ai/pori AlP No. 3-06-0250-33

Engineer's Report June 24,2014

• Circuits for which controls will be provided in the Tower and Vault will be Circuits 1 through 10 shown below in Table A.

If Additive Alternate No.1 is accepted, a new Airfield Lighting Computer and Monitoring

System (ALCMS) will be furnished and installed in the vault and in the Air Traffic Control Tower.

The following conditions and requirements shall apply for the lighting control system:

The existing L821 control system in the Tower and in the vault will be removed and replaced with a new Airfield Lighting Computer and Monitoring System (ALCMS).

• The existing L821 control system will remain in operation in the Tower and in the vault until the new ALCMS is installed and is fully operational. At the discretion of the Contractor, the existing L821 control system in the Tower can be abandoned up to two weeks before the new ALCMS is operational provided the existing L821 control system in the vault remains operational at all times until the new ALCMS is installed and operational.

• A new ALCMS will be furnished and installed to provide control from the Tower cab and vault to all airport lighting systems.

New fiber optic control cables will be installed between the Tower and vault in existing conduit to control the new ALCMS.

Controls will be rewired in the Tower and vault as necessary to accommodate the new ALCMS.

Circuits for which controls will be provided in the Tower and vault will be as shown on Table A. Circuits 1 through 10 will have controls provided for at this time, but the ALCMS will be designed such that additional circuits, as indicated by Circuits 11 through 22, can be added at a future date as needed. The ALCMS will be designed to also control these additional circuits by revising the computer program for the ALCMS computers.

The ALCMS will be designed such that the airfield lights and facilities can be controlled at the vault or at the Tower. Switching and monitoring will be installed that will indicate which computer is in control.

VI. AIRFIELD LIGHTING AND SIGNAGE

It is proposed in this project to replace all existing high intensity runway edge lights with

new quartz high-intensity runway edge light assemblies and to replace all medium intensity

taxiway edge lights with new LED medium intensity taxiway edge light assemblies. The edge

light assemblies will include new transformers and existing L867 light bases complete with new

base plate gaskets and new bolts.

Taxiway Circuits 1, 2, 3, and 4 are on the south side of the runway and all of these

circuits have to be on when you are operating the airport. Currently there is 27.32 KW total load

on these four circuits, which decreases to 16.1 KW if you replace the lights with LED. The

taxiway circuit on the south side of the runway will be reconfigured to two new circuits that can

be powered by two of the existing 10 kW and 7.5 kW regulators. Taxiway 0 lighting will be

separated from the existing taxiway circuit and powered by one 4 kW regulator so this taxiway

can be lighted separately from the other taxiways. The lighting on the helipad will be separated

from the taxiway circuits and powered separately by one of the existing 4 kW regulators.

To allow for replacement of any future damage to the new lights, the contractor will be

required to provide 15 new quartz high intensity runway edge lights and 15 new LED medium

intensity taxiway edge lights for the project, including the light fixture, the light base, lenses, and

isolation transformers. The Contractor will also provide to the Airport spare quartz high-intensity

runway edge light lenses and LED taxiway edge light lenses. Spare 120W and 10/15W

isolation transformers will also be provided to the Airport.

Electrical loads on each new circuit have been calculated and are included in Table B.

In all cases the calculated loads are less than the regulator capacity.

In order to meet FAA. standards, four existing distance remaining signs will be

removed, including sign and the transformer, and delivered to the Airport. All existing sign face

panels on existing distance remaining signs will be relocated.

Identification tags will be installed on all lights and signs on the airport.

VII. CONSTRUCTION SCHEDULING

It has been specified that the construction of the total Base Bid project will be completed

in 40 working days. If Additive Alternate No.1 is accepted, 20 additional working days will be

added to the contract time.

The Contractor will be confined to the designated Contractor's Storage and Staging Area

and access to this area during all times that the Air Traffic Control Tower (ATCT) is closed. The

ATCT is operational 7 days per week from 7:00 a.m. to 9:00 p.m. No work will be accomplished

by the Contractor between the hours of 9:00 p.m. and 7:00 a.m.

In order to minimize interference between Contractor operations and aircraft operations,

the following operational requirements will be instituted:

a. Aircraft shall at all times have the right of way.

b. During construction work on Runway 11 L-29R and taxiway sections within the Runway Safety Area (RSA) the runway will be closed. During these closures, Airport Management will place lighted runway closure crosses at each threshold of the runway. This will take place in a three consecutive week period. Runway 11 R-29L will be open for all aircraft operations during this period.

c. Runway 11 L-29R can only be closed for construction Monday through Thursday and on those days from 7:00 a.m. to 12:30 p.m. and from 2:30 p.m. to 6:00 p.m.

d. When Runway 11 L-29R is open, the Contractor will move all personnel, equipment, supplies, and materials out of the RSA for the runway, fill all trenches and excavations, cover all light bases, and assure that all runway and taxiway lighting systems are operational.

Stockton Metropolitan Ai/port AlP No. 3-06-0250-33

Engineer's Reporl June 24, 2014

e. Each night during construction Runway 11 L-29R will be open, all airfield lights and lighted signs will be operational, and all RSA standards adhered to. All lights will be operational but the Contractor will be allowed to install up to 2,000 feet of cable on the ground outside the runway pavement each night.

f. When airline or other large aircraft are operating Contractor, after receiving notification from the ATCT, will pull back outside of the safety area.

g. When Contractor is working adjacent to taxiways, the ATCT will divert aircraft around Contractor's operations when possible and Contractor will move back out of the taxiway safety area when aircraft must operate in these areas.

h. Runway 11 R-29L will be closed to all aircraft operations when the Contractor is working within the RSA (150 feet wide) for the runway. During periods of runway closure, Airport Management will place lighted runway closure crosses at each threshold to the runway. Prior to opening Runway 11 R-29L to aircraft, the Contractor will fill all trenches and excavations and cover all light bases. Contractor will be allowed five (5) consecutive working days to perform all work within the RSA for Runway 11 R-29L.

i. When work is being performed on a taxiway lighting system, every effort will be made to divert aircraft away from the taxiway, but when aircraft need to use that taxiway the Contractor will be notified and will immediately move all personnel and equipment back 50 feet from the edge of the taxiway. Whenever the Air Traffic Control Tower allows the complete closure of a section of taxiway, the Contractor will furnish and install lighted barricades at each end of the taxiway to be closed. All taxiways will be reopened each night.

j. For all runway closures the Airport will furnish lighted runway closure crosses at the thresholds at the ends of the runway at the start of construction and remove them at the end of the work day or at the end of construction.
