Our Company will at all times keep roads and footpaths, affected by his operations, free from soil and material spillage and properly repaired at his expense if the road is damaged by those operations. Our Company will keep the length of the Project construction areas in such condition that traffic will be accommodated safely. Traffic control devices and services will be provided and maintained both inside and outside the Project limits as needed to facilitate traffic guidance will this be necessary. 1.2.7 Number of Lanes for Traffic Control The existing number of traffic lanes of the roads that may be affected by the Project will be maintained at all times during the work execution and if diversions are provided these must be of the same traffic capacity as the original road. Notwithstanding the above, the Engineer may give approval to reductions in traffic capacity if our Company can show that these will not cause excessive delay to traffic.The detailed of Temporary road for each section will be designed and submitted to the Engineer.1.2.8 Vertical Clearance In general any temporary works placed over roads or diversions used by public traffic will have a vertical clearance specified by the Vietnamese Standards TCVN5729-97, TCVN4054-85, 22TCN210-92, TCVN5729-97 and 22TCN210-92, as follows: Expressways and Highways Class I, II and III at least 4.75 m Highways Class IV, V and VI at least 4.50 m Roads Class A and VII at least 3.20 m Roads Class VIII at least 2.70 m Where required by the Engineer, our Company will erect and maintain suitable approved check-gates, fitted with warning signs indicating the vertical clearance. 1.2.9 Haft-Width ConstructionOur Company will include in his Traffic Control Plan and his proposed method for construction described in the Programmer, pertinent details of the construction method to be applied where a detour is not feasible and the construction on existing public roads will be undertaken only over a half of the full width of the roadway. The following aspects will be considered for this purpose:The length of such half-width construction will be kept as short as possible.Work on culverts must be commenced and completed in the dry season and the embankments adjacent to them must be reinstated so that at least half the full width will be available for use by the public throughout the next rainy season.A single lane at least 3.5m wide will be kept open to traffic.Our Company will conduct his operations in such a manner as to cause the least possible obstruction, inconvenience, and delay to traffic and will be responsible for adequate control of the traffic using such lengths of single lane.1.2.10 Lines of Communication, Interaction & Communication Procedure:The Communication Lines will adapt with the actual and physical site condition and to suit the actual construction work procedure and sequence that will be carried out at site. It will be read in order to describe clearer Our Companys planning of traffic control during construction period and each station. However, it will be subject to further revisions based on changes on actual physical site conditions during the construction stage.The Communication will be made between the local traffic authorities and other related authorized agencies prior to the implementation of the traffic diversion.Traffic control plan approved by each authority will be distributed to the each related authorities prior to the commencement.The Communication facilities and services will be provided and maintained both inside and outside the project limits as needed to facilitate traffic guidance. All traffic control devices and facilities will be removed upon completion of the Contract.1.2.11 The Communication Line ChartProject ManagerRelated Authorities The Employer - Ministry of Transport - Project management unit - Local transport office The Engineer: NK, JBSI & TEDI Local Police/Traffic police Highway maintenance board Road management authority Commune committee Traffic Control Manager Site Manager Safety ManagerSite Engineer Implementing Staff Traffic ManMaintenance WorkerDrawing 1-1-2The Communication Chart for the implementation of Traffic Control Plan 1.2.12 Traffic Supervisor Our Company will employ Traffic Supervisors (TS) who will be under the Safety Department throughout the construction period and these TS will be entirely connected with the safety plan on the site. Our Company will ensure that these TS is suitably qualified and experienced persons who will be supervise and monitor in full compliance with the Traffic Control Plan.Our Companys Traffic Supervisors will maintain a daily logbook which will be keep record of daily traffic safety / control activities. Photographs will be considered as part of the record.1.3 Traffic Control Plan For Station at Flyover1.3.1 General planOverall traffic diversion is shown on the drawing Plan of Traffic Assurance. The concept of traffic control management for this project will be based on three parts: - Sign post for traffic assurance- Manpower to introduce the traffic- Temporary road (if any)Our Company will maintain the public road traffic during the performance of the Works by keeping open to traffic on existing roads or bypass traffic over a detour.Diversion road and temporary road will be planned at the points of which the travel on existing traffic roads is affected by construction activities.1.3.2 Diversion and Temporary Road Planning to construct NH38B Flyover, NH37 Flyover, PR391 Flyover, PR191D Flyover, PR191P Flyover 1.3.2.1 Construct temporary roadThe temporary road network is built along the existing way (NH37, PR391, PR191D, PR191P) for the purpose of construction only. The Temporary access road is shown on the drawing Plan of Traffic Assurance.Our Company will arrange supervisors to assure for the safety during construction, using, maintenance and protection. 1.3.2.2 Construct main road at Interference with existing roads The process of constructing main road expressway at Interference with existing feeder roads will be divided into two stages:Stage 1: Public traffic on existing road will be maintained. Our Company will execute the feeder roads and fly-over bridges as mentioned above.Stage 2: After finishing the feeder roads and fly-over bridges, start to close the existing road and construct expressway at Interference. In order to minimize disruption to traffic flows, our Company will enclose the site with temporary fence to provide a visual barrier between the work area and adjacent traffic. The movement of men, materials and plant into and out of the barrier area will be checked, controlled by flagman or security. 1.3.2.3Current Traffic Condition and Construction ActivitiesThere are existing public road crossing the expressway. It is so heavy traffic volume. It interferes in soft ground treatment works, filling works, paving works, and viaduct works.1.3.2.4Traffic Control ManagementIn order to comply with requirement of tight working schedule, the following process is basically proposed as a working sequence. All the existing traffic will be diverted to the temporary road and diversion road through out construction period. However, in area where the diversion road is crossing the working area, secondary diversion will be applied. The area and period of this diversion is limited. Sign panels, barricades, cones, vertical panels and other traffic control devices will be set to ensure safety of traffic at detour roads or at the intersection between existing road and diversion roads. Flagman will be provided if required.Guide for traffic and regulate the facilities going and coming through the construction area will be provided in conformity with the traffic line.Traffic will also be instructed in proper manner to ensure construction progress of the site and absolute safety for the vehicles and people.The following device and facilities will be prepared to control the traffic in safety manner and they will be removed depending on the construction activities on site.A. Various kinds of site boarding will be set to control the traffic and separate the traffic road away the construction site.B. The flashing light and warning signs will be installed to draw the attention of public. C. Flagman will be provided at road intersection if required.1.3.2.5 Traffic Control Plan For NH38B FlyoverA. Proposed Road Traffic ManagementOverall traffic diversion is shown on the Plan of Traffic Assurance. The concept of traffic control management for this project will be based on two parts: - Sign post for traffic assurance- Manpower to introduce the trafficOur Company will maintain the public road traffic during the performance of the Works by keeping open to traffic on existing roads or bypass traffic over a detour.B.
