Section 622 Section 622 use of the Engineering Personnel for such time as considered necessary , but no longer than the date of final release from maintenance on the project. The use, location, relocation and removal shall be under the direction and control of the Engineer and no portion of the building shall be occupied, or otherwise used by the Contractor, unless permitted by the Engineer in writing and subject to any provisions or limitations set forth in such written permission. When no longer needed, and upon specific instructions of the Engineer, each building shall be removed from the project.
622.04 Method of Measurement. Each specified Engineer's field office building
conforming to the requirements of the contra ct and including all facilities and utilities as specified will be measured as a unit lump sum quantity. When a Type 2 LO or Type 3 LO building is specified and the Contractor furnishes separate units as provided in Subsection 622.03.1.2, B, no additional measurement will be made because of the separate units but will be made as if the specified single unit had been furnished.
622.05 Basis of Payment. The Engineer's field office buildings or combination field
laboratory and office building furnished as sp ecified and measured as prescribed above will be paid for at the contract unit price per each, which price shall be full compensation for all materials, design, construction, furnishi ng, maintaining; for all fuel, water, sewage disposal, telephone service, electricity, including transformer if necessary, moving to and from the project and movements on the project, all as specified or directed by the Engineer as provided in the contract, and for all cost s incidental thereto. When the Engineer determines that the necessary location of the building is such that electrical current must be carried for the exclusive use of the Engineer for a distance in excess of 1,000 feet from its source, the cost of furnishing service lines in excess of 1,000 feet will be paid for as Extra Work. Payment for each Engineer's field office bui lding or LO building provided in accordance with the contract will be made in two installmen ts. Sixty-five (65) percent of the contract price will be paid on the first monthly estima te after occupancy by the Engineer and the remaining thirty-five (35) percent will be paid when the use of the building has been concluded by the Engineer as provided herein. Payment will be made under: 622-A: Engineer's Field Office Building, Type ____ - per each 622-B: Engineer's Field Office Building, Type ____ LO - per each SECTION 623 - DRAINAGE WICKS
623.01 Description. This section shall cover the work of furnishing and installing
drainage wicks of the types, sizes and at th e designated locations, all in accordance with the details specified on the plans and in these specifications or as directed by the Engineer. This section shall also cover the work of drilling holes through the embankment layer at locations specified on the plans or directed by the Engineer. Jetting methods will not be permitted. The Engineer may vary the depths, spacings or number of drainage wicks to be installed, and may revise the plan limits for this work as necessary.
623.02 Materials. The drainage wick shall be a prefabricated type composed of a
drainage plastic core wrapped in a non-woven geotextile. The core shall be fabricated with suitable drainage channels. The non-woven geotextile wrap shall meet the following minimum specifications: Property Value Test Method Tensile Strength 30 lbs./in. ASTM D 4632 Permittivity 0.15 sec-1 ASTM D 4491 The core material shall be constructed in such a manner that the filter geotextile has a minimum surface area of 3.50 square inches per inch that is not in contact with the core material. The core channels shall have a mi nimum free volume of 0.16 cubic inch per inch. The Contractor will be required to furnish to the Engineer three copies of a certified test report from the producer, showing all data required to indicate compliance with the above specifications and with certification that the material meets such specifications. The certifications by the manufacturer or di stributor will be prima-facie evidence of the materials meeting the specified requirements. All drainage wick materials will, however, be subject to approval by the Engineer.
623.03 Construction Requirements.
623.03.1 Equipment. In general, it shall be the Contractor's responsibility to select the
proper size and amount of equipment to provide the desired results, but certain basic items shall be provided, as outlined herein. The type of carrier to be used will depend upon the desired installation force, but it shall be equipped with a mandrel or sleeve of minimum cross sectional area not to ex ceed fourteen square inches which will protect the wick material from tears, cuts and abrasions during installation. The Contractor shall secure approval of all equipment prior to beginning work and any equipment found unsatisfactory shall be pr omptly replaced or supplemented. All equipment approved for use shall be on a trial basis. If the equipment proves unsatisfactory after a short test section, it shall be re moved, replaced or su pplemented as deemed necessary to accomplish the desired results.
623.03.2 Installation. At least two weeks prior to the installation of the drainage wicks,
the Contractor shall submit details of the sequence and method of installation to the Engineer for review and approval. Approval by the Engineer of the sequence and method of installation shall not necessarily constitute acceptance for the duration of the project. If, at any time, the Engineer considers that the method of installation does not produce a satisfactory drainage wick, the Contractor shall alter the installation method and/or equipment as necessary to comp ly with these specifications. The Contractor will be permitted to use augers or other approved methods to loosen stiff upper soils prior to the installation of the drainage wicks. These holes shall have a maximum diameter just large enough to permit the mandrel or sleeve carrying the wick and wick anchorage to penetrate the embankment and shall extend not more than two feet into the underlying highly compressible soil. The drainage wick shall be installed at the designated locations using a mandrel or sleeve that completely encloses the drainage wick , thereby protecting it from tears, cuts and abrasions during installation. The mandrel, with the wick inside, shall be forced vertically into the ground to an elevati on specified on the plans or directed by the Engineer. The mandrel shall be retracted leaving the wick in place to function as a vertical drain. The wick shall be cut neatly at its upper end with an eight-inch length of wick material protruding above the existing embankment surface. The equipment shall be carefully checked for plumbness prior to advancing each wick and must not deviate more than one inch per foot from the vertical. Wicks that are out of their proper location by more than six inches, dama ged in construction or improperly completed shall be rejected by the Engineer, and no co mpensation will be allowed for said rejected wicks. The Contractor shall provide a suitable means of making a linear determination of the depth of the drainage wick at any given time and of the quantity of wick material used at each vertical drain location. The Contractor shall observe precautions necessary for protection of instrumentation devices and shall replace at no additional cost to the State an y equipment that is damaged or becomes unreliable as a result of the Contractor’s operations. Embankment or surcharge to be placed over an area in which drainage wicks are installed shall be allowed to settle the period of time as specified on the plans. In the case of bridge approach embankment fills, no end bent piling may be driven until the specified waiting period has elapsed. The waiting period begins when the total embankment and/or surcharge has been constructed to grade. If no settlement monitoring devices are specified on the plans, the Contractor may propose to provide, install and maintain subsidence/settlement plates and essential appurtenances for the Engineer to measure the amount of settle ment that occurs. If the data taken from these settlement plates show that the amount of settlement is sufficient, or that the rate of settlement has declined to the point that little additional settlement will occur during the specified waiting period, the Contractor will be relieved of the total waiting period requirement. In the case of bridge approa ch embankment fills, the end bent piling may then be driven without further delay. The settlement measuring devices shall be approved by the Engineer.
623.04 Me thod of Measurement. Drainage wicks will be measured by the linear foot
for the full length of drainage wicks, comple te and in place. No separate measure for payment will be made for loosening of stiff upper soils by augering or other approved methods.
623.05 Basis of Payment . Drainage wicks, measured as prescribed above, will be paid
for at the contract unit price per linear foot, which price sha ll be full compensation for all drilling of holes, furnishing all materials, inst allation of drainage wicks and for all labor, equipment, tools and incidentals necessary to complete the work. Payment will be made under: 623-A: Drainage Wicks - per linear foot SECTION 625 - PAINTED TRAFFIC MARKINGS
625.01 Description . This work consists of furnishing materials and applying
reflectorized painted traffic markings and high build painted traffic markings in reasonably close conformity with these specifications and the details shown on the plans or established.
625.02 Materials . Paint shall be the color specified and shall meet the applicable
requirements of Section 710. Application of permanent painted traffic markings shall require Class B (High-Visibility) glass beads. Otherwise, Class A (Standard) glass beads shall be required. Glass beads shall meet the requirements of Subsection 720.01. Blue - ADA marking material shall meet the requirements of Section 710 with the exception that the color shall be Blue - ADA.
625.03 Construction Requirements .
625.03.1 Equipment . All paint shall be applied by approved mechanical equipment
providing constant agitation of paint, traveling at controlled speeds, with one or more paint "guns" synchronized to begin and cut off paint flow automatically for skip lines, and subject to manual control for continuous lines of varying length. The machine, or a separate machine, shall be equipped with a glass bead dispenser adjusted and so synchronized with the paint applicator as to distribute the beads uniformly on the painted lines within 10 seconds. Calibration charts and devices for measurement of tanks shall be provided by the Contractor for determining the quantity being applied. All painting equipment and operations shall be under the control of an experienced technician thoroughly familiar with the equipment, materials, and marking layouts.
625.03.2 Preparation of Surface . All areas to be painted shall be thoroughly cleaned.
Cleaning may be done by hand brooms, rotary brooms, air blast, scrapers, or whatever combination of equipment is necessary to clean the pavement thoroughly without damage to the surface. Before edge striping, particular care shall be taken to remove all vegetation, loose soil, and the like from the area to be painted. Should other methods fail, the surface shall be wetted with a water jet and scrubbed as necessary to dislodge all foreign material. After washing, the surface shall be allowed to dry thoroughly, and all films of dried mud apparent after surface drying shall be removed before application of paint. Painting shall follow as closely as practicable after the surf ace has been cleaned and dried, but no paint shall be applied until the surface has been insp ected and permission gi ven to proceed. The cost for preparing the surface sh all be included in the contract unit prices for the marking items. Upon request, the Engineer will establish control points for markings, by type and color,
