The detergent shall be of such composition and shall be added in such quantity that the specified cleaning is accomplished. Any residue, detergent or other foreign material which may accumulate on cleaned surfaces shall be removed by flushing with fresh water. Steam cleaning shall not be performed more than two weeks prior to starting painting operations or other phases of cleaning. Subsequent painting shall not be performed until the cleaned surf aces are thoroughly dry and in no case in less than 24 hours after cleaning.
3.Hand Cleaning: Manual or powered wire brushes, hand scraping tools, power grinders, or sandpaper shall be used to remove all dirt, loose rust, mill scale, or paint which is not fi rmly bonded to the surfaces.
4.Water Blast Cleaning: Water blast cleaning shall be done in accordance with NACE (National Association of Corrosion Engineers) Standard RP -01-72 with normal water, no additives to the water will be allowed. All areas of oil and grease on surfaces to be coated shall be hand cleaned with clean petroleum solvents.

Areas of structural steel to be field welded shall be masked and the remainder of the steel shall be given one coat of primer. As soon as practicable after being accepted by the Engineer and prior to removal from the shop, machine- finished surfaces shall be coated with a rust inhibitor which can easi ly be removed. Surfaces of milled or finished iron and steel castings shall be painted with one coat of primer. Erection marks for field identification of steel members and weight marks shall be painted upon surface areas previously painted with the primer.
3.Intermediate Coat: The intermediate coat shall be appropriately tinted to contrast with the primer . The dry film thickness of the intermediate coat shall not be less than 2.0 mils. After ere ction of steel structures has been completed, including all riveting, welding, bolting , and any straightening of bent metal, all adhering rust, scale, dirt, grease, and other foreign material shall be removed as specified under Subsection 610- 3.02 of the specifications. All areas where the primer is damaged or deteriorated shall be thoroughly cleaned and spot painted with the same type of paint used for the primer and to the specified dry film thickness. When the spot painting coat is thoroughly dry, the i ntermediate coat shall be applied. In no case shall a succeeding coat be applied until the previous coat has dried throughout the full thickness of the paint film.
4.Topcoat: All small cracks and cavities which have not become sealed in a watertight manner by the intermediate coat shall be filled before the topcoat is applied. At the option of the contractor, the intermediate coat and the topcoat may be applied in the shop. When f inished coats are applied in the shop, the contractor shall repaint all damaged or deteriorated areas in the field as directed by the Engineer. The dry film thickness of the topcoat shall be not less than 2.0 mils.

Pavement markings shall be removed to the fullest extent possible from the pavement by any method that does not materially damag e the surface, color, or texture of the usable pavement. Abrasive blasting, using air or water, is an acceptable method for removing pavement markings, however, other methods may be approved by the Engineer. Overpainting of markings with paint or asphalt will not be permitted. Sand or other material deposited on the pavement as a result of removing pavement markings shall be removed as the work progresses. Accumulations of sand or other material, which might interfere with drainage or might constitute conditions adverse to traffic safety, shall be removed by the contractor. Where blast cleaning is used for the removal of pavement markings or for removal of objectionable material, the residue, including dust, shall be removed immediately after contact betw een the sand and the surface being treated. Such removal shall be by a vacuum attachment operating concurrently with the blast cleaning operation, or by other methods approved by the Engineer. Blast cleaning shall not be used within 12 feet of a lane occupied by public traffic unless a suitable barrier separates traffic from the area being cleaned. TABLE OF CONTENTS INDEX SECTION 701 Obliteration or removal of raised pavement markers shall include removal of the marker and adhesive pad, or adhesive pad alone if the marker is missing. Any damage to the pavement caused by pavement marking removal shall be repaired by methods acceptable to the Engineer.

Elements of Work specified under this subsection which are lost, stolen, destroyed, or are deemed unacceptable by the Engineer, while in use on a project shall be replaced by the contractor and, e xcept as hereinafter specified for temporary impact attenuators, at no additional cost to the Department. Elements of Work will be measured for payment as follows:
A.Elements of Work (Complete -in-Place): The Elements of Work listed herein under Subsection 701- 5 of the specifications will be measured for payment upon the satisfactory completion of the initial installation or obliteration. Except as hereinafter specified under Basis of Payment, no subsequent measurements will be made.
B.Elements of Work (In Use): The elements of work listed herein under Subsection 701- 6 of the specifications will be measured for payment from the time at which the element is put into active use on the project and accepted by the Engineer until such time that the Engineer determines that the element is no longer required. 701- 4.02 Relocation of Work Elements: Following the initial installation of an Element of Work described above, the Engineer may direct the contractor to move the Element of Work from one location and reinstall it at another location. Except as specified elsewhere herein, in Subsection 701 -5.01 of the specificati ons for Temporary Concrete Barrier (Installation and Removal), and Subsection 701- 5.02 of the specifications for Temporary Impact Attenuators (Installation and Removal), no measurement for payment will be made for relocation of Work Elements. When work of a progressive nature is involved, such as resurfacing a road under traffic, or closing a lane or lanes for work to be accomplished during a shift, no measurement for payment will be made for setting up or relocating the necessary traffic control equipment, workers, devices, facilities, signs etc., that are moved concurrently with the advancing operation, or removal at the end of a shift.

Measurement for payment will not resume until the beginning of the work shift following that work shift in which those elements are restored to usefulness.
B.Substantial Deficiencies: For each work day or work shift during which there are, as determined by the Engineer, substant ial deficiencies in the contractor's traffic control plan, devices, and/or services, no payment will be made to the contractor for any Element of Work listed herein under Subsection 701- 4.01(B) of the specifications. Measurement for payment will not resume for any Element of Work until the beginning of the work day or work shift following that work day or work shift in which all corrective measures have been performed by the contractor and approved by the Engineer. In cases of serious or willful disregard for the safety of the public or its employees by the contractor, the Engineer may place the traffic control elements in proper condition and deduct the cost thereof from monies due or becoming due the contractor.
C.Nondiligent Prosecution of Work: In t he event that the Engineer determines that the contractor's construction operations are not resulting in the diligent prosecution of the work under contract, no payment will be made to the contractor for the Elements of Work listed herein under Subsection 701-4.01(B) of the specifications until such time as the Engineer determines that the contractor is devoting appropriate efforts toward completion of the work.
