Spec Section/ Drawing Sheet Question/Comment Response

1 Section 32 13 70

On plan sheet 7 of 7 the detail regarding Strip Seal Joint Replacement indicates to “remove and replace elastomeric gland in kind”. The existing concrete, steel extrusion and armoring angles are “to remain”. Specification Section 32 13 70 has references to shop drawings for armoring angles and asks for submittal of welder qualifications. Can you confirm that the scope of work for this item includes only the removal and replacement of elastomeric glands and does not include any structural steel work? Or please clarify the scope.

PART 3 EXECUTION

3.1 INSTALLATION OF EXPANSION JOINT SEALS

Applies to all strip seal joint replacement locations.

3.1.1 Time of Installation

Strip seal joint system shall be set to the proper width for the ambient temperature at the time of installation in accordance with manufacturer's recommendations. The environment shall be free of dust, oil, grease, wax, moisture, and frost. The gap wall surfaces must be thoroughly cleaned.

Joints shall be sealed immediately following the final cleaning of the joint walls. No installation may be performed in rainy weather, or when rain is expected within one hour before installation. All surfaces must be completely dry prior to applying adhesive. Personnel shall read the Material Safety Data Sheet for all components before beginning the installation.

3.2 SEALING OF JOINTS

All expansion joint systems are to be installed in strict accordance with the manufacturer's instructions by manufacturer's approved installers or under the supervision of manufacturer's technicians. The joint seal shall be cut to the correct length of the appropriate gap for installation, without pulling or exerting excess tension. The seal shall be installed in the longest practicable lengths.

Clean and abrade sides of joint seal per the manufacturer's instruction.

Mix adhesive according to manufacturer's directions only after all preparation of gap and joint seal are complete. Apply adhesive according to manufacturer's recommendations. Joint seal shall be gradually inserted into the gap, without stress or compression. The in-place joint seal shall be in an upright position and free from twisting, distortion, and cuts.

Adjustments shall be made to the installation equipment and procedure, if the stretch exceeds 1 percent. Any seal exceeding 2 percent stretch shall be removed and replaced. The installer shall maintain the joint seal at the depth desired, by hand or by any convenient means. The expansion joint seal shall be placed so that the top of seal is 1/2 inch, plus or minus 1/8 inch, below the pavement surface. No part of the seal shall be allowed to project above the surface of the pavement. Clean away excess adhesive.

Clean all excess adhesive around the edges and top of the joint with a trowel or scraping tool.

3.3 DELETED

3.4 PROTECTION

Contractor shall perform all work with care so that any material which is to remain in place will not be damaged. If any of these materials are

Section 32 13 70 Page 4 damaged, the damaged material shall be repaired or replaced in a manner satisfactory to the Government at no extra cost to the Government.

3.5 CLEAN-UP

Upon completion of the work, all unused materials shall be removed from the site, any adhesive on the pavement surface shall be removed, and the pavement shall be left in clean condition. Any damage to the seal or joint during cleaning shall be repaired by the Contractor at no cost to the Government.

3.6 QUALITY CONTROL PROVISIONS

3.6.1 Application Equipment

The application equipment shall be inspected to assure uniform application of adhesive to the sides of the expansion joint seal or the walls of the joint. If any equipment causes cutting, twisting, nicking, excessive stretching or compressing of the seal, or improper application of the adhesive, the operation shall be suspended until causes of the deficiencies are determined and corrected.

3.6.2 Procedures

3.6.2.1 Quality Control Inspection

Quality control provisions shall be provided during the joint cleaning process to prevent or correct improper equipment and cleaning techniques that damage the concrete in any manner. Cleaned joints shall be approved by the Government prior to installation of the adhesive and expansion joint seal. In-place joint seal which fails to meet the specified requirements shall be removed and replaced with new joint seal at no cost to the Government.

3.6.2.2 Conformance to Stretching and Compression Limitations

Conformance to stretching and compression limitations shall be determined.

The top surface of the expansion joint seal shall be marked at 1 foot intervals in a manner clear and durable to enable length determinations of the seal. After installation, the distance between the marks shall be measured on the seal. If the stretching or compression exceeds 2 percent, the seal shall be removed and replaced with new joint at no additional cost to the Government. The seal shall be removed up to the last correct measurement. The seal shall be inspected at each location for compliance to the shrinkage or compression requirements. Measurements shall also be made at the same interval to determine conformance with depth and width of installation requirements. Expansion joint seal that is not in conformance with specification requirements shall be removed and replaced with new joint seal at no additional cost to the Government.

3.6.2.3 Pavement Temperature

The pavement temperature shall be determined by placing a thermometer in the joint adjacent to the pavement and the reading shall be recorded. The thermometer shall remain in the joint for an adequate time to provide a control reading.

Section 32 13 70 Page 5

3.6.3 Final Inspection

The expansion joint seal and adhesive shall be inspected for proper rate of cure, deleted, cuts, twists, nicks and other deficiencies. Seals exhibiting any defects, at any time prior to final acceptance of the project, shall be removed from the joint, wasted, and replaced in a satisfactory manner at no additional cost to the Government.

3.7 MEASUREMENT AND PAYMENT

3.7.1 Strip Seal Joint Replacement

The work specified in this section for Strip Seal Joint Replacement will not be measured for payment and all costs in connection therewith shall be paid for at the contract price for each strip seal replacement location.

Payment for Option 2, Bid Item No. 12, entitled "Strip Seal Joint Replacement" shall include all work specified herein.
