The Contractor shall be required to obtain a NASA Dig Permit for all locations where the tree stumps require grinding. (As Applicable) o Prior to any work, the Contractor shall site verify all elevations and locate all existing underground utilities in the area of the proposed excavation or underground work. The Contractor shall not begin work until utility locations have been marked. The NASA POC will coordinate the utility markings. No excavation or ground disturbance is allowed to start without first receiving a NASA Dig Permit. (As Applicable)

Stump removal operations shall avoid unnecessary soil excavation and ground disturbance. (As Applicable)

Soil and debris shall be managed to prevent materials from reaching storm drains. (As Applicable)

If an active bird nest is observed in a tree designated for removal, do not remove tree; contact the NASA POC.

Safety:

The Contractor shall be responsible for initiating, maintaining, and supervising all safety precautions and programs in connection with the performance of work and shall comply with all applicable laws, ordinances, rules, and regulations. Work can be halted if proper safety measures are not followed.

Work shall conform to the latest revision of American National Standards Institute Standard Z- 133 (Safety Requirement for Pruning, Trimming, Repairing, Maintaining, Removing Trees, and for Cutting Brush).

A safety plan and traffic control plan shall be submitted to and approved by the NASA POC prior to beginning any tree removal activities. (As Applicable)

Traffic Control:

Traffic control is the total responsibility of the Contractor and shall be coordinated with the NASA POC and the proper NASA Offices (i.e., Security Services Branch). The Contractor shall be solely responsible for pedestrian and vehicular safety and control within the worksites to give safety, protection, and warning to persons and vehicular traffic within the area.

o The Contractor shall provide, erect, and maintain all necessary barricades, lights, danger signals, and warning signs, and take all necessary precautions for the protection of the workers and safety of LaRC employees. All barricades and signs shall be in accordance with the Manual of Uniform Traffic Control Devices. (As Applicable) o Blocking of streets shall not be permitted unless prior arrangements have been made with the NASA POC and coordinated with appropriate offices.

Clean Up:

Clean-up procedures shall be completed within 2 hours after debris has been placed around the site of each tree requiring removal. The work site shall be left equal to or cleaner than pre-work conditions. It shall be the responsibility of the Contractor to remove and dispose of off-site in a proper and acceptable manner all logs, brush, and debris resulting from the tree maintenance operations. (As Applicable)

Period of Performance:

Unless otherwise directed or approved in advance by the NASA POC, removal operations shall be completed within 30 days of receiving the Notice to Proceed.

Hours of Operation:

All work shall be performed between the hours of 6:00 a.m. and 6:00 p.m. (Eastern Time), Monday through Friday. Any exception to the work schedule must be approved in advance by the NASA POC. Unless otherwise directed, no work will be allowed on any federal holiday.

The Contractor shall at all times conduct operations to ensure the least inconvenience to LaRC staff. The Contractor shall coordinate and schedule work to cause the least interference with the normal flow of employee traffic.

Badging:

All Contractor employees shall follow proper badging requirements and procedures as identified by the NASA POC prior to and during the period of performance.

Inspections:

The NASA POC shall be notified before 8:30 a.m. on mornings of each working day of exact location of that day’s work. The NASA POC will inspect work at his discretion.

Damages:

Damages done by the Contractor to any person or property, public or private, are the total responsibility of the Contractor and are repaired or compensated for by the Contractor to the satisfaction of both injured party and the NASA POC at no cost to NASA.

o Nearby trees and/or infrastructure shall be protected during removal. The Contractor shall control activities to prevent damage to nearby trees, equipment, and utilities. The Contractor shall be responsible for any damage to existing equipment or infrastructure at no additional cost to NASA.

o If another tree is damaged or killed during the work, the Contractor shall coordinate with the NASA POC to develop a repair or replacement strategy at the Contractor’s expense.

Any tree damage caused by the Contractor shall be repaired immediately at no additional expense to the satisfaction of the NASA POC. Trees damaged beyond repair, as judged by the NASA POC, are removed at no expense to NASA and replaced by a tree of size and species designated by the NASA POC at no additional expense to NASA, or the dollar value of such damaged trees, as determined by NASA, is deducted from the monies owed the Contractor.
