7−14 704.03 CONSTRUCTION METHODS. Manholes and catch basins shall be reconstructed in the following sequence: First the structures shall be thoroughly cleaned. Next, the cast iron frames and covers (or grates) are carefully removed and stockpiled on the site for subsequent reuse. Then, the tops of the structure immediately below the castings are removed. Subsequently, a portion of the vertical walls of the structure is removed to a depth sufficient for the reconstructed unit to make the transition to the lines, grades, and dimensions indicated on the Plans, or as directed by the Engineer. Any excavation required around the existing drainage structure shall be carried out in such manner as to cause the least disturbance to both the surrounding area and those portions of the existing structure that are to remain. Actual reconstruction of the drainage structures shall then commence in accordance with the details indicated on the Plans or as directed by the Engineer. Construction methods to be employed in this effort shall conform to the applicable requirements as set forth in Subsection
702.03.1 of these Specifications.
704.04 METHOD OF MEASUREMENT. "Reconstruct Catch Basin and Manhole/Corbel Cones"
will be measured by the number of the tops of such units actually reconstructed. "Reconstruct Catch Basin and Manhole/Vertical Walls" will be measured by the vertical height in linear feet of drainage structure walls actually reconstructed in accordance with the Plans and/or as directed by the Engineer. 704.05 BASIS OF PAYMENT. The accepted quantity of "Reconstruct Catch Basin and Manhole/Corbel Cones" will be paid for at the contract unit price per each such cone as listed in the Proposal. The accepted quantity of "Reconstruct Catch Basin and Manhole/Vertical Walls" will be paid for at the contract unit price per vertical linear foot as listed in the Proposal. The prices so-stated constitute full and complete compensation for all labor, materials and equipment for reconstructing drainage structures including removing, stockpiling and resetting castings, excavation and backfill, examining and cleaning the existing basin before and after reconstruction, the legal disposal of all surplus excavated and/or unsuitable materials, and all incidentals required to finish the work, complete and accepted by the Engineer. CATCH BASIN TO CATCH BASIN WITH GUTTER INLET
705.01 DESCRIPTION. This work consists of reconstructing existing Type "D" catch basins, either
square or round, into catch basins with gutter inlet conforming to the details and at the locations indicated on the Plans, or as directed by the Engineer, all in accordance with these Specifications. 705.02 MATERIALS. Materials used in reconstructing existing Type "D" catch basins shall conform to the requirements of Subsection 702.02.1; Masonry Unit Construction , of these Specifications. 7−15
705.03 CONSTRUCTION METHODS. Catch basins shall be thoroughly cleaned. If repairs are
required, they will be made and paid for under the provisions of SECTION 704; RECONSTRUCT CATCH BASINS AND MANHOLES , of these Specifications. The existing granite inlet stones and the existing frames and covers are to be retained if they are in good condition. If the existing granite inlet stones or the existing frames and covers are not in good condition, they shall be replaced and paid for under the applicable provisions of SECTION 702; MANHOLES, INLETS, AND CATCH BASINS , of these Specifications. All concrete inlet stones, regardless of condition, shall likewise be replaced. Actual reconstruction of the Type "D" catch basins shall then commence in accordance with the details indicated on the Plans. Construction methods to be employed shall conform to the applicable requirements as set forth in Subsection 702.03.1 of these Specifications. In special cases, the referenced construction methods may be revised and/or modified by the Engineer. 705.04 METHOD OF MEASUREMENT. "Reconstruct Existing Type "D" Catch Basin to Catch Basin and Gutter Inlet" will be measured by the number of such catch basins actually so-modified in accordance with the Plans and/or as directed by the Engineer. 705.05 BASIS OF PAYMENT. The accepted quantity of "Reconstruct Existing Type "D" Catch Basin to Catch Basin with Gutter Inlet" will be paid for at the contract unit price per each such modified structure as listed in the Proposal. The price so-stated constitutes full and complete compensation for all labor, materials, and equipm ent including removing and reconstructing existing walls, excavation, backfill, examining and cleaning the existing basin before and after reconstruction, saw cutting and matching of the full pavement and sidewalk depth, gravel borrow, compaction, concrete and for all incidentals required to finish the work, complete and accepted by the Engineer. Furnishing and installing new "Precast Concrete Inlet Stones,” "Granite Inlet Stones,” "Metal Frames and Grates,” and "Metal Frames and Covers " will not be included in the above contract unit prices but will be paid for separately as set forth in Subsection 702.05 of these Specifications. "Reconstruct Existing Catch Basins" will not be included in the above contract unit price but will be paid for separately as set forth in Subsection 704.05 of these Specifications. SECTION 706 PLUG AND CAP PIPE - ALL SIZES
706.01 DESCRIPTION. This work consists of providing plugs and caps for various sizes and types
of pipe at locations indicated on the Plans or as directed by the Engineer, all in accordance with these Specifications. 7−16 706.02 MATERIALS. Plugs and caps for cast iron pipe shall be of the type approved by the utility company for a particular application.
a.Plugs and caps for vitrified clay pipe shall be of the type recommended for this purpose by the manufacturers of said pipe.
b.Cement or brick masonry plugs shall consist of approved cement or brick masonry units securely bedded with cement mortar.
c.Cement mortar shall conform to the requirements of Subsection M.04.03.5 of these Specifications. 706.03 CONSTRUCTION METHODS. The plugs described above shall be placed in all lines where indicated or directed when such lines are broken into during construction. All such plugs shall produce watertight joints. Plugs and caps installed in pressure lines shall be properly strapped and blocked to withstand the anticipated back pressure. Vitrified clay and cement or brick masonry shall be properly and securely set in place, blocked and protected to preclude infiltration or exfiltration due to hydrostatic pressure. 706.04 METHOD OF MEASUREMENT. "Plug and Cap Pipe All Sizes" will be measured by the number of each such unit actually installed regardless of the size or type. 706.05 BASIS OF PAYMENT. The accepted quantity of "Plug and Cap Pipe All Sizes" will be paid for at the contract unit price per each such unit as listed in the Proposal. The price so-stated is full and complete compensation for all labor, materials and equipment required to provide said plugs or caps and for all incidentals required to finish the work, complete and accepted by the Engineer.
