SCOPE OF WORK:

1. Surface preparation:

i. Remove any visible oil, grease or salt contaminants.

ii. All steel surfaces must be prepared in accordance with SSPC-SP 2 (Hand Tool Cleaning), SSPC-SP 3 (Power

Tool Cleaning) and SSPC-SP 11 (Power-Tool Cleaning to Bare Metal) Standards. SP11 must only take place when

necessary. Following hand and power tool cleaning, all surfaces must be brushed, blown clean with compressed air

or vacuumed to remove all dust, and debris before the application of any coating. The Contractor must prevent the

migration of debris, paint chips and dust to adjacent properties. All debris must be collected at the end of each

workday. No debris must be left on-site overnight, and the premises must be returned to a clean condition upon

completion of work.

iii. Hazardous Materials Requirements: The FAA completed lead, heavy metal (chromium and cadmium) and

polychlorinated biphenyl (PCB) sampling on the 75’ towers which were found to be detected. The contractor must

review the attached sampling report to ensure awareness of the presence of hazardous materials and must ensure that

all surface preparation work must comply with all local, state and federal requirements.

1. Summarized Results:

• Tower A: Detected lead-based paint, polychlorinated biphenyls, chromium and cadmium.


• Tower B: Detected lead-based paint, chromium and cadmium. PCBs were found to be not detected but Contractor must assume PCBs are present.


• Tower C: Detected lead-based paint, polychlorinated biphenyls, chromium and cadmium.


• Tower references are shown in a diagram in the last page of the sampling report.

a. Contractor must submit on a project specific Health and Safety Plan mitigating all hazard identified in the tower sampling report. All work must be completed in accordance with OSHA, EPA, SSPC/AMPP Standards and all other relevant standards. The Contractor must have a class 3P containment to prevent debris from spreading outside the worksite. See submittal section for all required submittals.

b. All waste must be disposed according to Connecticut Department of Energy and Environmental Protection and EPA regulations and disposed at waste facilities that accept the associated hazardous materials.

c. Contractor must provide a manifest in accordance with all federal, state and local standards.

2. Spot Prime Coat: All bare steel surfaces must receive one spot prime coat of Tnemec Series 135 Chembuild epoxy, or approved equal, in color 1243 Metallic Aluminum at 4-6 mil Dry Film Thickness (DFT). Follow all manufacturer requirements.

3. Full coat: Apply full coat of Tnemec Series 135 Chembuild epoxy, or approved equal, in color DC74 Off-White at 4-6 mil DFT on all exterior surfaces. Follow all manufacturer requirements.

4. Full Finish Coat: Apply one full finish coat of Tnemec Series 1095 Endura-Shield polyurethane, or approved equal, at 2.5-3.5 mils DFT on all exterior surfaces. Follow all manufacturer requirements.

5. The towers are equipped with a ladder and rail combination MSA dynaglide ladder safety system. The ladder safety system is hot dip galvanized, approximately 15 years old and in good condition. The contractor must only prepare and coat the ladder where it mounts to the tower. The Contractor must remove any paint that is mistakenly placed inside the fall arrestor channel, so it does not affect the performance of the system.

6. Remove rust at the conduit threads at the base of each tower. Coat with above coating system.

7. Measure thickness of coatings according to SSPC-PA 2. Take 4 sets of 3 individual readings per tower for each coat. Provide to the FAA copies of these results.

8. Apply new silane concrete sealer to existing exposed concrete foundation surfaces.

9. At the base of each tower is a bare #6 ground, partially in rigid conduit, that is clamped to a tower leg with a washer and structural bolt. Remove the #6 and associated rigid conduit to 1.5’ below grade. Remove the existing bolt that was used to clamp the #6 and replace with an ASTM A325 bolted connection to include bolt, hardened washer, nut and palnut. Bolted connection must be

hot dip galvanized. Contractor to verify dimensions on site.

10. Contractor must install a new hot dip galvanized 1/4” thick A36 steel plate in the middle of the platform on each

tower. Plate dimension is approximately 2.5’x2.5’. The purpose of the steel plate is to cover an existing hole in the

platform where a piece of equipment was removed. Redrill the existing six 3/8” bolt holes to ½” and install new ASTM A325 bolted connection. Contractor must verify and review all dimensions with the FAA. Contractor must remove the existing 3 metal strips

and six bolts that currently cover the platform opening.

11. The Contractor must review the provided as builts to ensure construction operations do not impact any existing equipment. The Contractor must protect the underground communication cables that travel from each tower to the stub ups at the building from heavy equipment.

12. The Contractor must be aware and plan for project phasing requirements that are listed below in the SOW.

13. Potential Additional Work (Contract Option #1): The Contractor must provide separate line-item pricing as part of their base bid proposal to coat the 200’ hot dip galvanized steel lattice tower. Based on funding, this option may or may not be added to the contract.
