A. You are responsible to provide for public safety. Compliance with this section does not relieve you of your responsibility for public safety.
B Construction activities must not inconvenience the public or abutting property owners. Schedule and conduct work to avoid unnecessary inconvenience to the public and abutting property owners. Avoid undue delay in construction activities to reduce the public's exposure to construction.
C. Where possible, route traffic on new or existing paved surfaces.
Maintain convenient access to driveways, houses, and buildings. When an abutting property owner's access across the right-of-way line is to be eliminated or replaced under the Contract, the existing access must not be closed until the replacement access facility is usable. Construct temporary approaches to cross streets.
Provide a reasonably smooth and even surface for use by traffic at all times. Install or construct culverts on only 1/2 the width of the traveled way at a time; keep the traveled way portion being used by traffic open and unobstructed until the opposite side of the traveled way is ready for use by traffic.
Upon completion of trenching, grading or placing any subsequent layer, bring the surface of the roadbed to a smooth and even condition, free of humps and depressions, and satisfactory for the use of the public.
After subgrade preparation for a specified layer of material has been completed, repair any damage to the roadbed or completed subgrade, including damage caused by public use.
While subgrade and paving activities are underway, allow the public to use the shoulders. If half-width paving methods are used, allow the public to use the side of the roadbed opposite the one under construction. If enough width is available, keep open a passageway wide enough to accommodate at least 2 lanes of traffic at locations where subgrade and paving activities are underway. Shape shoulders or reshape subgrade as necessary to accommodate traffic during subgrade preparation and paving activities.
D. Control dust resulting from the work, inside and outside the right-of-way. Apply a dust palliative for the prevention or alleviation of dust nuisance.
E. If a height differential of more than 0.04 foot is created by construction activities at a joint transverse to the direction of traffic on the traveled way or a shoulder subject to public traffic, construct a temporary taper at the joint with a slope of 2 foot horizontal to 1 inch vertical. For a taper on existing asphalt concrete or concrete pavement, construct the taper with cold or hot mix HMA. If authorized, you may use alternative materials or methods to construct the required taper.
F. Install signs, lights, flares, temporary barrier system, barricades and other facilities to direct traffic. Provide flaggers whenever necessary to direct the movement of the public through or around the work.
G. The City Engineer may order or consent to your request to open a completed section of surfacing, pavement, or structure roadway surface for public use. You will not be compensated for any delay to your construction activities caused by the public.
This does not relieve you from any other contractual responsibility. 702 PUBLIC SAFETY
A. Do not store vehicles, material, or equipment in a way that creates a hazard to the public or obstructs traffic control devices. Do not install or place temporary facilities used to perform the work which interfere with the free and safe passage of traffic. Install temporary illumination such that the illumination and the illumination equipment do not interfere with public safety. The installation of general roadway illumination does not relieve you from furnishing and maintaining any protective devices. Do not move or temporarily suspend anything over a traffic lane open to the public unless the public is protected.
B. Whenever your activities create a condition hazardous to the public, furnish, erect and maintain those fences, temporary barrier system, barricades, lights, signs, and other devices and take any other necessary protective measures to prevent damage or injury to the public.
C. Immediately remove spillage from a roadway.
D. Install temporary barrier system or other authorized protective systems under any of the following conditions:
1. Excavations: Where the near edge of the excavation is within 15 feet from the edge of an open traffic lane
2. Temporarily unprotected permanent obstacles: When the work includes the installation of a fixed obstacle together with a protective system, such as a sign structure together with protective railing, and you elect to install the obstacle before installing the protective system; or you, for your convenience and as authorized, remove a portion of an existing protective railing at an obstacle and do not replace such
railing completely the same day
3. Storage areas: When material or equipment is stored within 15 feet of the edge of an open traffic lane and the storage is not otherwise prohibited by the Contract
E. Installation of temporary barrier system is not required if an excavation within 15 feet from the edge of an open traffic lane is protected by any of the following:
1. Steel plate or concrete covers of adequate thickness to prevent accidental entry by traffic or the public
2. Side slope where the downhill slope is 4:1 (horizontal:vertical)
3. Barrier or railing
Offset the approach end of temporary barrier system a minimum of 15 feet from the edge of an open traffic lane. Install the temporary barrier system on a skew toward the edge of the traffic lane of not more than 1 foot transversely to 10 feet longitudinally with respect to the edge of the traffic lane. If the 15-foot minimum offset cannot be achieved, the temporary barrier system must be installed on the 10 to 1 skew to obtain the maximum available offset between the approach end of the railing and the edge of the traffic lane, and an array of temporary crash cushion modules must be installed at the approach end of the temporary barrier system. Secure temporary barrier system in place before starting work for which the temporary barrier system is required.
F. If you appear to be neglectful or negligent in furnishing warning devices and taking protective measures, the City Engineer may direct your attention to the existence of a hazard. You must furnish and install the necessary warning devices. If the City Engineer points out the inadequacy of warning devices and protective measures, that action on the part of the City Engineer does not relieve you from your responsibility for public safety or abrogate your obligation to furnish and pay for these devices and measures. 703 TRAFFIC & PEDESTRIAN CONTROL
