No work (except the commencement of emergency repair work in accordance with § 235-18 hereof) in or under a public way shall commence until the applicant shall have applied for, in accordance with § 235-15, and obtained from the awarding authority a street opening permit.
All work contemplated by this bylaw shall be done in a good and workmanlike manner using best engineering and construction practices and shall be done in accordance with:
All applicable laws and regulations;
All of the provisions of this bylaw;
Any conditions contained in the street opening permit; and
Such reasonable supplemental instructions not inconsistent with the foregoing as the awarding authority or its representative may from time to time issue.
A permit holder shall cause to be restored those portions of a public way disturbed by the permit holder to as good a permanent condition, in the reasonable judgment of awarding authority or its representative, as they were in when permit holder made application thereunder.
No person or entity may perform any work (including street opening work or emergency repair work) in or under a public way unless it is a permit holder and:
Is a municipal department or public utility or their respective officers or employees;
Is the holder of a current and valid public works construction license; or
Has engaged such a holder and such holder performs all such street opening work or emergency repair work as agent of permit holder.
The applicant shall file, on forms designated by the awarding authority, a completed and signed application at the office of the awarding authority (with a copy delivered simultaneously to the Highway Department) each time it desires to perform street opening work. The application shall be accompanied by any and all plans, certifications, certificates of insurance and other items specified in the application or reasonably requested by the awarding authority. If the applicant does not intend to perform the street opening work itself, it must in the application designate a licensed contractor to perform the work as its agent. The application shall also be accompanied by the application fee and the refundable deposit.
The Highway Department shall promptly review the application and make written recommendations concerning approval to the awarding authority and, if appropriate, shall include recommendations concerning permit conditions and supplemental instructions.
The awarding authority shall make a prompt determination on the application, taking into account the following and such other facts as it may reasonably consider:
If the application is considered favorably, a street opening permit containing such conditions and supplemental instructions as the awarding authority reasonably deems appropriate shall promptly issue. If the application is not favorably considered, the awarding authority shall communicate in writing to applicant the reasons its application was not favorably considered.
The amount of the refundable deposit to secure proper restoration of a public way after street opening work is determined in the reasonable judgment of the awarding authority based on the extent of the work. (A current schedule of deposits for standard work is available from the Town.)
Following notice given by permit holder that final permanent repairs to the public way have been completed, the awarding authority or representative will make a final inspection. Once the awarding authority or representative has concluded that permanent repair work has been satisfactorily concluded and that applicant has no other uncured defaults under street opening permits, it shall release the unexpended balance of the deposit serving as security for the street opening permit related to the inspected work.
All refundable deposits that an applicant submits for street opening permits shall be held by the awarding authority in one account which shall be designated as the applicant's refundable deposit account. Upon request, applicants may receive periodic reports as to the balance standing within this account. Should a deposit associated with a specific permit be insufficient to secure the proper repair of a public way following a default by the permit holder, the awarding authority, without limitation to other remedies available to it, can deduct the cost of the proper repair from applicant's refundable deposit account for the purpose of funding the proper repairs. To the extent required by Chapter 164 of the General Laws applicable to gas companies, the provisions of this section and § 235-17 hereafter shall not apply to gas companies which affirmatively claim exemption in their application for street opening permits.
From time to time hereafter, the awarding authority, after public notice and hearing, may amend the schedule of deposits, the application fee, the hourly after-hours inspection charges or any other amounts due under this bylaw. A reasonable hourly charge for inspectional services which must be performed outside of normal working hours in accordance with a posted schedule established by the awarding authority will be billed to the permit holder and due and payable 15 days after billing. In extraordinary situations where extensive installation or renewal of utility lines overburden the normal capacity of the municipal departments to conduct inspections, the awarding authority can, after notice to the permit holder, or as a condition of the permit, elect to treat all inspections as after-hours inspections and bill the permit holder accordingly. Applicants which are municipal departments are exempt from payment of all fees and deposits hereunder. Public utilities, to the extent exempted as provided in § 235-16 above, are exempt from payment of all fees except the application fee.
If the conditions for emergency repair work exist, then an applicant, after giving oral, faxed or electronic notice to the Police and Highway Departments, may commence street opening work. All such emergency repair work shall be done in strict compliance with this bylaw except for compliance with any notice provision inconsistent with such emergency action.
On the business day following the commencement of emergency repair work, the applicant shall file with the awarding authority (i) a written statement setting forth in detail the facts and circumstances constituting the conditions for emergency repair work, (ii) an application for a street opening permit covering the street opening work already commenced in accordance with § 235-15, (iii) the filing fee and required refundable deposit. If all of the materials such as plans, etc. are not then available to applicant, applicant will supply them as soon as available. The awarding authority will promptly process the application and grant the street opening permit with such conditions and supplemental instructions as it may reasonably require.
The permit holder and/or each licensed contractor shall acquire and continuously maintain while it possesses any street opening permits liability insurance coverage on all personnel and equipment to be used in the street opening work, which insurance is to be with insurance companies licensed to do business in the Commonwealth of Massachusetts and shall contain the following coverages and be in the following minimum amounts:
Commercial general liability insurance including operators, independent contractors, complete operations, XCU hazards, broad-form property damage and personal injury.
Automobile liability insurance, covers owned, nonowned and hired vehicles.
Certificates of insurance shall provide for at least 30 days' notice to the awarding authority of cancellation or material change. The name of the municipality shall be listed as an additional insured on the certificate of insurance.
Any contractor or other person or entity that wishes to perform work on a public way and which is not either a municipality or a public utility (including their respective officers or employees) must be licensed by the awarding authority. Application for a public works construction license must be made on a yearly basis. (See appropriate sections of the General Bylaws.)
Term of permit. All street opening permits shall be valid for 30 days and, upon written request to the awarding authority, renewable for an additional 30 days. Permits must be present at the work site. Permits can be revoked by the awarding authority if the applicant is in default.
The permit holder or contractor will notify the awarding authority representative when an inspection is desired and coordinate the timing of such inspection.
Working hours. Except in emergency situations, street opening work will occur during normal working hours. The permit holder must give notice of the intended street opening work 72 hours in advance to the Highway Superintendent, and, unless the requirement for a police detail is waived by the Police Chief of the municipality, must arrange for and pay for a police detail to be present throughout the period of time that street opening work is being conducted.
Dig-safe. The permit holder shall, in accordance with all current laws of the Commonwealth of Massachusetts, notify all public utilities 72 hours in advance of making any excavation in a street. Such notification shall be made by means of obtaining a DIG-SAFE number. Said number shall be provided on the street opening permit application. The permit shall not be issued until this information is provided.
Existing utilities. Before starting any excavation, the permit holder or contractor must confer with all public utilities to obtain information from each as to the horizontal and vertical locations of existing utilities and other conditions that may affect the excavation. The permit holder or contractor shall not interfere with any existing utility without the written consent of the awarding authority representative and the owner of the utility. If it becomes necessary to relocate an existing utility, this shall be done by its owner and the cost of such work shall be borne by the permit holder. The permit holder or contractor shall inform itself as to the existence and location of all underground utilities and protect the same against damage.
Protection of existing lines and structures. The permit holder or contractor shall adequately support and protect by timbers, sheeting, etc. all pipes, conduits, poles, wires, cables or other appurtenances which may be in any way affected by the excavation work and shall do everything necessary to support, sustain and protect them under, over, along or across such work area. The excavation work shall be performed and conducted in such a manner that it shall not interfere with access to fire stations, fire hydrants, water gates, underground vaults, catch basins or any other public structure.
Adjoining property. The permit holder or contractor shall, at all times and at its own expense, preserve and protect from injury any adjoining property by providing proper foundations and shall take such other precautions as may be necessary for this purpose. The permit holder or contractor shall at all times and at its own expense shore up and protect all buildings, walls, fences, trees and other property likely to be damaged during the progress of the street opening work and shall be responsible for all damages to public or private property or streets resulting from its failure to properly protect and carry out said work. The permit holder or contractor shall not remove, even temporarily, any trees or shrubs which exist in planting strip areas without first obtaining the consent of the Highway Superintendent.
Damaged trees. In the event a tree is either accidentally destroyed by the permit holder or contractor or is authorized for removal by the awarding authority representative, the permit holder or contractor shall remove the tree, stump and debris from the work site, and replace the tree with an identical species with a minimum caliper of two inches in the identical location.
Pedestrian crossings; open trenches. The permit holder or contractor shall, where possible, maintain safe crossings for two lanes of vehicle traffic at all public intersections as well as safe crossings for pedestrians at intervals of not more than 300 feet. If any excavation is made across a public way, it shall be made in sections to assure maximum safe crossing for vehicles and pedestrians. An open trench may not exceed 300 feet unless specifically permitted by the awarding authority or its representative. If the public way is not wide enough to hold the excavated material for temporary storage, the material shall be immediately removed from the location.
Traffic. The permit holder or contractor shall take appropriate measures to assure that during the performance of the street opening work, so far as practicable, normal traffic conditions shall be maintained at all times so as to cause as little inconvenience as possible to the occupants of the adjoining property and to the general public. The awarding authority representative may permit the closing of streets and walks to all traffic for a period of time. Unless the requirement for a police detail is waived by the Police Chief of the municipality, the permit holder shall engage a police detail to maintain traffic control and public safety at the project site while street opening work is in progress. Warning signs shall be placed a sufficient distance from the project site in order to alert all traffic coming from both directions. Cones or other approved devices shall be placed to channel traffic. Warning signs, lights and such other precautions shall conform to the Manual on Uniform Traffic Control Devices. Construction materials and equipment on the site shall be limited in quantity and in the space they occupy so that they do not unduly hinder and block traffic.
Gutters and basins. The permit holder or contractor shall maintain all gutters free and unobstructed for the full depth of the adjacent curb and for at least one foot in width from the face of such curb at the gutter line. Catch basins shall be kept clear and serviceable.
Excavated material. The permit holder or contractor shall remove all excess excavated material, surplus water, muck, silt, residue or other run-off pumped or removed from excavations from the site.
Temporary repairs. At the end of each day, all trenches must be plated if repair work is not completed and/or backfilled, compacted and temporarily patched on the day repair work is completed. No open, unplated trenches are permitted overnight, and work in plated trenches must be continually prosecuted to completion to minimize the time trenches are plated.
Noise. The permit holder or contractor shall perform the work in such a manner as to avoid unnecessary inconvenience and annoyance to the general public and occupants of neighboring property. During the hours from 10:00 p.m. to 7:00 a.m., the permit holder or contractor shall not use, unless otherwise specifically permitted by the awarding authority or awarding authority representative, any tool, appliance or equipment producing noise of sufficient volume to disturb the sleep or repose of occupants of the neighboring property.
Debris and litter. All debris and litter remaining from the street opening work site shall be removed by the permit holder or contractor in a timely manner.
Restoration of pavement markings. All permanent pavement markings (crosswalks, center lines, fog lines) which are damaged during street opening work shall be restored in kind by and at the expense of the permit holder.
Lawn surfaces and plantings. All lawn surfaces which are disturbed during street opening work shall be replaced with sod or six inches of screened loam, lime, fertilized and reseeded with good-quality lawn seed. Any areas containing plantings shall be restored to their original condition with the same or similar plantings.
Erosion control. The permit holder shall be responsible for all erosion control and for obtaining any necessary permits from the Conservation Commission. The permit holder or contractor shall protect drainage structures from siltation by whatever means required, including but not limited to the installation of hay bales and/or filter fabric. In the event that a drainage structure becomes damaged from siltation as a result of the street opening work, the permit holder or contractor shall clean the structure before completing the temporary patch.
All street opening work and materials used therein must conform to the Massachusetts Department of Transportation's Standard Specifications for Highways and Bridges, 1995 Edition, and with the Americans with Disabilities Act and the Architectural Access Board Regulations as currently in effect. In addition, the following specific requirements also apply. Exceptions to these requirements may be made in the discretion of the awarding authority or awarding authority representative at the time that the street opening work is in progress.
Excavation. Existing pavement shall be cut in neat, true lines along the area of the proposed excavation. Unstable pavement shall be removed over cave-outs and breaks and the subgrade treated as the main trench. Pavement edges shall be trimmed to a vertical face and neatly aligned with the center line of the trench. Cut-outs beyond the limits of the trench lines must be normal or aligned parallel to the center line of the trench. Excavations shall be made in open cut. Trenches and excavation shall be braced and sheathed in accordance with the requirements of the Occupational Safety and Health Act (OSHA). Sections of bituminous or cement concrete sidewalks shall be removed to the nearest scoreline or approved cut edge.
Backfilling and compaction.
Excavations shall be filled with approved backfill. Approved backfill consists of either controlled density fill, suitable excavated material or gravel meeting M1.03.0 or M1.03.1 of the Standard Specifications. The permit holder may select which of these three to use in the excavation. "Suitable excavated material" shall mean previously excavated granular material but which does not include blacktop, clay, silt, organic material, concrete, roots, boulders or stones larger than four inches in diameter. If the hole is to be filled with suitable excavated material, a backfill course shall be placed in approximately twelve-inch lifts of maximum compaction to four inches below asphalt grade (See Diagrams 1, 2, and 3.) A base course consisting of four inches of processed gravel or equivalent (i.e., suitable excavated material containing no stones larger than 1 1/2 inches in diameter) shall then be placed on top of the backfill course. The backfill and base course shall be compacted to not less than 95% of maximum dry density as determined by the modified Proctor Test in accordance with ASTM 1557 Method D. The permit holder, if directed by the awarding authority or its representative, will retain at its expense a professionally qualified geotechnical consultant to perform this test. The results of this test shall be given to the Highway Superintendent.
If controlled density fill is used as backfill material, it must contain a minimum of 250 pounds of Class F fly ash or high air (25% plus) and be self-leveling. It must be Type 1E or 2E (very flowable). Flowable fill is to be batched at a ready-mix plant and is to be used at a high or very high slump one inch to 12 inches. In lieu of the slump test, a six-inch-long, three-inch-diameter tube may be filled to the top and then slowly raised. The diameter of the resulting "pancake" may be measured, and the range of the diameter shall be nine inches to 14 inches. It shall be flowable, require no vibration and, after it is placed, be excavatable by hand tools and/or small machines.
The ingredients shall comply with the following:
Types 1E and 2E must meet the following requirements:
If controlled density fill is used as backfill material, it must fill the excavation to immediately below asphalt grade. The contractor must then plate the excavation with a heavy-duty steel plate adequate to carry heavy traffic and wait 24 hours for the CDF to cure prior to applying the permanent patch.
If an excavation is backfilled with controlled density fill in accordance with this bylaw, then a temporary patch need not be installed but a permanent patch may be installed immediately. Permanent patches installed over controlled density fill shall consist of four inches of bituminous concrete applied in a 2 1/2 inch base course and a 1 1/2 inch top course of bituminous concrete, all installed in accordance with this bylaw. If an excavation in a cement concrete public way is filled with controlled density fill, then the provisions of Subsection E(1) may be omitted, but the provisions of Subsection E(2) and (3) must be complied with.
Bituminous concrete. Following proper compaction, a temporary patch, which shall be the thickness of the existing asphalt pavement or a minimum of four inches, whichever is greater, shall be applied. It shall consist of either cold patch or bituminous concrete plant-mixed hot asphalt aggregate. (See diagrams.)
Temporary patch to be maintained for one year. A temporary patch that has been backfilled and compacted shall be maintained by the permit holder or contractor so that the patched surface and the surrounding area remain a single smooth, unbroken plane for a period of time no shorter than one year after placement of the temporary patch.
Except when installed over controlled density fill as described in Subsection B above, permanent patches shall be installed not less than 12 months nor more than 18 months from the date of installation of the temporary patch. Upon request by the permit holder or contractor, the awarding authority representative will inspect the temporary patch and determine if final settlement of the trench has occurred. The awarding authority representative will notify the permit holder or contractor within seven days of the inspection whether the permanent patch can be installed. Public utilities or municipal departments may schedule permanent patches to replace all temporary patches then within the permanent patch window without receiving prior approval from the awarding authority but must give the awarding authority and its representative not less than 72 hours' prior notice.
A permanent patch shall consist of one of the following: a) cold planing the temporary patch to a depth of 1 1/2 inches and then installing a minimum of 1 1/2 inches of top course of bituminous concrete, or b) the excavation of the temporary patch in a bituminous concrete public way and replacement of this material with any additional processed gravel needed and 2 1/2 inches of base course and 1 1/2 inches of top course of bituminous concrete (See Diagrams 1 and 2.) or (c) application of the infrared process to the temporary patch, or d) the certification by the awarding authority representative made during the permanent patch window that the temporary patch, in his reasonable judgment, meets fully the standard of a permanent patch and thus requires no further work.
Cold planing. If the cold planing method is used, the area to be cold planed must extend at least 12 inches beyond all sides of the existing temporary patch. (See Diagram 2.) This area must be cold planed to a depth of 1 1/2 inches. Any broken or irregular edges of existing pavement shall be cut away in straight lines, leaving a sound vertical face at least 12 inches back from all edges of the existing pavement. The permit holder must provide a dust control system capable of complying with environmental air quality standards during cold planing and sweep the public way following completion of the cold planing work. All abutting edges of the existing pavement will be painted with an asphalt emulsion immediately prior to the placement of the permanent patch. The permanent patch will consist of the application of a top course of a minimum of 1 1/2 inches of bituminous concrete plant-mixed hot asphalt aggregate. After raking and rolling, the grade of the permanent patch shall match the existing bituminous surface of adjacent pavement. The finished permanent patch shall be level, having no depressions retaining water on any of the surfaces. All seams of the finished perimeter shall be sealed with penetrating asphalt emulsion.
Any temporary patch that has been patched with cold patch must be excavated and replaced with a bituminous concrete base in accordance with this subsection. If the excavation method is chosen and if additional cutting of the existing pavement is required, it shall be done in neat, straight lines. Any broken or irregular edges of existing pavement shall be cut away in straight lines, leaving a sound vertical face at least 12 inches back from all edges of the existing pavement. (See Diagrams 1 and 3.) All abutting edges of the existing pavement shall be painted with an asphalt emulsion immediately prior to the placement of the permanent patch. The permit holder or contractor shall remove and dispose of all excavated material and thoroughly compact the surface of the subbase.
Following excavation, the permanent patch shall consist of a bituminous concrete base and top laid and rolled in two courses. The binder (base course) shall be a minimum of 2 1/2 inches in depth and the top course shall be 1 1/2 inches in depth. The minimum total thickness of both courses, measured after rolling, shall be four inches or equal to the material that was previously excavated. If, after compaction, more than four inches of permanent patch are needed in order to restore the excavated area to finish grade, additional bituminous concrete shall be used in the base course. The base course shall be placed and carefully raked and thoroughly rolled to the required thickness. The top course shall be placed to a grade that will match the existing bituminous surface after rolling. All seams of the finished perimeter shall be sealed with penetrating asphalt emulsion. The finished permanent patch shall be level, having no depressions retaining water on any of the surfaces.
If the infrared process is utilized to install the permanent patch, the area to be repaired shall be thoroughly cleaned to eliminate all potential contaminants. An infrared heater shall be positioned over the area to be repaired for a period of time required to plasticize the existing pavement to a depth of 1 1/2 inches. Oxidation of the pavement caused by improper heating techniques must be avoided. If this condition occurs, all oxidized material must be removed and replaced with Class I bituminous concrete meeting the Standard Specifications of the Massachusetts Department of Transportation.
The softened area shall be inwardly reworked from approximately one foot beyond all sides of the original temporary patch. This designated area shall be treated with a penetrating asphalt emulsion, uniformly scarified and raked to a workable condition. For street crossings and/or trenches with jogs, the reworked area will be extended beyond the outermost jog in a straight line parallel with the opposite outermost jog. Under no circumstances may the infrared heat-treatable patching mix that is used register a temperature under 200° F.
After the paving mixture has been properly admixed and raked to grade, compacting shall be obtained by use of a steel-wheeled roller of sufficient weight to establish a uniform density comparable to that of the surrounding pavement surface within the work area. The finished permanent patch shall be level, having no depressions retaining water on any of the surfaces. All seams of the finished perimeter shall be sealed with penetrating asphalt emulsion.
A petroleum resin sealant shall be applied consistently to the entire heated area by mechanical means or hand application at an approximate rate between 0.1 and 0.25 gallon per square yard. The actual rate will be determined on site by an approved absorption test method. A mineral filler will then be broadcast over the newly sealed area to absorb any excess liquid and prevent tracking and the area immediately opened to traffic.
Certification. If a permit holder seeks to qualify a temporary patch as a permanent patch, it must make the application for inspection set out above and specify in it its request for certification. The awarding authority representative will notify the permit holder within 30 days of the request whether the temporary patch has been certified as a permanent patch. If it is not so certified, the permit holder shall forthwith cause a permanent patch utilizing one of the three remaining methods set out above to be utilized.
Newly paved roads. On newly paved roads, the awarding authority representative may require, in addition to the placement of the permanent patch, that the permanent patch shall be treated by a process (infrared, microwave or equivalent) that will ensure that the permanent patch is integrated into the existing bituminous surface in a seamless manner.
Final inspection of permanent patch. Following completion of the permanent patch, the permit holder or contractor shall give notice thereof to the awarding authority representative, who shall inspect the permanent patch. If the awarding authority representative is satisfied that the road has been restored to as good a condition as existed prior to the street opening work, he shall so note on the street opening permit and any refundable deposit securing that street opening work shall be refunded promptly to the applicant. If the awarding authority representative determines that the permit holder is in default, the awarding authority may proceed in accordance with § 235-24, Remedies, of this bylaw.
Special rules for cement concrete roadways. Any excavation in a cement concrete public way or public way with a cement concrete base with a bituminous concrete surface shall be backfilled as described in Subsection B and temporarily patched as described in Subsection C. Immediately prior to the installation of a permanent patch, the following shall be done:
The temporary patch and sufficient backfilled material shall be removed.
A six-inch reinforced concrete slab shall be laid over the backfilled trench extending one foot beyond all edges of the trench surface and allowing for four inches of bituminous concrete to be installed above the slab. The slab shall have steel reinforcing for tensile strength in accordance with good engineering practices. The permit holder or contractor shall install a temporary heavy-duty steel plate adequate to carry heavy traffic over the trench until the concrete slab shall have adequately cured.
Once the concrete slab shall have cured, there shall be installed a four-inch layer of bituminous concrete applied in a 2 1/2 inch base course and a 1 1/2 inch top course, all in accordance with Diagram 3 and generally in accordance with this bylaw.
Shoulders. Suitable excavated material shall be placed in layers not to exceed six inches in depth and compacted. Shoulders shall be reconstructed to their existing condition and either loamed with six inches of loam, limed, fertilized and seeded with roadside grass mix or covered with four inches of wood chips as directed by the awarding authority representative.
Sidewalks. Any excavation in a concrete or bituminous concrete sidewalk shall require that the entire sidewalk area containing the trench be replaced. Any concrete sidewalk section that is excavated or damaged by the excavation must be replaced in its entirety. Suitable excavated material or gravel shall be placed in layers not to exceed six inches in depth and compacted. All sidewalk areas will be installed by the permit holder or contractor in conformance with the ADA and the Architectural Access Board Regulations currently in effect. Bituminous concrete sidewalks shall have two courses (two inches of binder and one inch of top) of bituminous concrete plant-mixed hot asphalt aggregate applied to and rolled to create a pavement surface consistent with the adjacent bituminous concrete surface. Concrete sidewalks shall have four inches of poured concrete applied to finish grade. The concrete shall be placed in alternate slabs nine meters in length except as otherwise ordered. The slabs shall be separated by transverse preformed expansion joint filler 13 millimeters in thickness. Concrete driveway openings shall have six inches of poured concrete applied to finish grade. Preformed expansion joints will be installed against buildings, walls, steps, foundations or existing concrete block.
