DESCRIPTION

15100 Section 152. MOBILIZATION WITH TEMPORARY TRAFFIC CONTROL Requirements

151.01 Mobilization This work consists of moving personnel, equipment, material, and incidentals to the project and performing all work necessary before beginning work at the project site. Mobilization includes the obtaining of permits, insurance, and bonds. Do not disturb material, drainages, and vegetation outside the road prism limits.

635.01 Temporary Traffic Control. See section 63500

106.00 All equipment proposed to be used for performance of the work must be of the size, type, number and in such condition to properly pursue the requirements of this contract. Grading equipment must be capable of cutting, crowning and shaping operations necessary to meet the requirements of Activity Codes applicable in the technical (performance standards) requirements and Typical Section Drawings.

The Contractor's proposed equipment must be made available for inspection prior to award of the contract. If at any time during the course of this contract the equipment is deemed unsatisfactory, the CO may order removal and may require a satisfactory replacement, at Contractor's expense. Replacement equipment, if ordered, is to be onsite and working within 48 hours.

Any movement or transportation of equipment to or from work areas required to pursue the work on designated roads, to repair or replace equipment, or for the Contractor's convenience must be at the Contractor's expense.

Speed Limit. An operating speed limit for all equipment operating or performing operations of any kind other than movement for transportation, will not, at any time, exceed 5 miles per hour.

Work conducted by vehicles moving over 5 miles per hour will be considered as unsatisfactory.

Moreover, any damage caused by vehicles or workers are the responsibility of the Contractor.

Failure to comply with the speed limit will be considered a safety violation and the final measures of enforcement will be issued by the CO.

Worker Safety Training. An extremely important safety strategy. The type and amount of training depends on job duties and responsibilities of assigned workers to tasks. Training is needed to operate most tools and machinery. Training should provide information on the use of personnel protection equipment, occupational hazards and health risks, and other pertinent topics.

Many resources are available to ensure that workers receive proper work zone safety training, including commercial training services and products. The National Work Zone Safety Information Clearinghouse has many training resources relevant to highway worker safety at http://www.workzonesafety.org/. These include a variety of free training resources developed through the national Work Zone Safety Grant program see at http://www.workzonesafety.org/fhwa_wz_grant. As part of the grant effort, the Roadway Safety Program+ is a valuable software training tool that can be downloaded free of charge.

In addition to all the topics listed above, it contains safety training modules on:

• excavation, equipment operation, and electrical work.

• runovers/back overs, falls, sprains/strains, struck/crush injuries; and

• health issues associated with outdoor working environments.

The FHWA also maintains a database of worker training programs available at:

http://ops.fhwa.dot.gov/wz/outreach/wz_training/worker_safety.htm.

Many unions and trade associations also offer highway work zone safety training.

Depending on the duties of the worker, training pertaining to the various worker safety training programs should provide instruction consistent with the requirements described in ANSI/ASSE A10.47-2009: Work Zone Safety for Highway Construction standard. The training should also be consistent with other national standards pertaining to highway work zone design and operation (e.g., the Roadside Design Guide, the national MUTCD, etc.).

Actions That Lead to Good Risk Management. Managing risk requires an initiative-taking approach. Below is a set of actions that may be taken to improve their risk management position.

• Requiring and implementing regular work zone traffic control inspections as a matter of policy.

• Moving in a timely manner to resolve any deficiencies in a reasonable and timely fashion, which may include notifying others and following up on their response.

• Installing signing or other notifications for a hazardous condition if an immediate resolution is not possible or is too expensive, and documenting how and why this decision was reached; and

• Demonstrating a priority list of actions on deficient conditions if fiscal constraints prevent immediate action.

Safe and Effective Work Zone Inspections. The key to a successful work zone inspection program can be summed up with four critical elements. The must have:

• Overarching policies that clearly spell out responsibilities and competencies for individuals involved in the work zone inspection program communicating from agency to project levels.

• A monitoring program that regularly evaluates the effectiveness of agency policies and project-level actions.

• A standardized procedure for program and project deficiency identification and follow-up; and

• A process that fold’s feedback on performance back into the program.

These guidelines should provide the practitioner with the necessary knowledge to accomplish the following objectives:

• Recognize the value of work zone inspections to:

o Increase safety for workers and motorists.

o Increase compliance with applicable design standards and Federal requirements.

o Improve mobility through the work zone; and o Serve as an agency risk management tool.

• Set up a program – by establishing inspection program elements at the project levels to help develop a comprehensive, initiative-taking, and effective work zone inspection program, or confirm and enhance elements currently in place.

• Make a program successful and maximize benefits – this is accomplished by proper training, effective policies, making the inspection program an integral part of doing business for the agency, and ensuring there is a feedback mechanism to fold performance analyses back into the inspection program.

• See the big picture – seeing how the various components of project-level inspections interrelate with the agency’s statement of objectives.

Measurement

151.02 Measure the Section 151 items listed in the bid schedule according to Subsection 109.02.
