- Description
- 19Z0003 Ponce de Leon Inlet, North Jetty Repair Project - Stone Acceptance Criteria Chart The U.S. Army Corps of Engineers, Jacksonville District is issuing this request for information as a means of conducting market research to identify parties having the capability of providing jetty stone for the Ponce de Leon Inlet, North Jetty Repair Project. The project is scheduled to be awarded in the spring of 2019. There is no solicitation at this time. This request for information does not constitute a request for proposals; submission of any information in response to this market survey is purely voluntary; the government assumes no financial responsibility for any costs incurred. Description of Project: Work consists of repairs to restore the North Jetty at Ponce de Leon Inlet in Volusia County, Florida. Repairs will require substantial moving and manipulation of both new and existing stones to obtain the required interlocking within the tolerances provided. The North Jetty is approximately 3,855 feet in length with a height of 7.2 feet above mean lower low water (MLLW). Mobilization of equipment and the construction necessary to repair the jetty shall be water-based and require the use of marine construction methods and equipment. Work also consists of constructing a new concrete base for a U.S. Coast Guard Aid to Navigation (ATON) at the seaward extent of the existing jetty crest, and constructing and attaching a new ATON to the newly constructed base. Base construction and placement will require removing and resetting surrounding existing armor stone so the base is meshed and interlocked with the surrounding armor stone. Jetty Stone Requirements: Stone Material Quality All stone material shall be free of any detrimental geologic features such as, but not limited to, clay seams, shale seams, argillaceous material, any styolites, schistose seams, detrimental vugs zones or seams, zones of high foliation, and/or other adverse diagenetic features or seams. No schistose stone material or any highly foliated stone material will be acceptable. Sedimentary or metamorphic stone containing carbonaceous, coal, clay seams/lenses/joints or similar deleterious features will not be permitted or accepted. All stone material utilized shall be free of cracks, blast fractures, bedding seams, foliation seams, foliation joints, joints, "any" deleterious features such as splits, spalls, delaminations, disaggreations, dissolvement, shalely parting, or combination thereof of such features, and/or other defects that would tend to increase its deterioration from natural causes. An independent, state licensed Professional Geologist, licensed in any U.S. State that issues a Professional Geologist License, shall determinate if the aforementioned features are present within stone material from any of the proposed Stone Source(s). Discussion of Stone Material Quality and any detrimental or deleterious features present within any source shall be included in Evaluation Testing of Stone and the Stone Source Submittal for that Stone Source. Examples of deleterious and detrimental features in stone can be viewed in ERDC/TR GL-81-8. Engineering Manual EM 1110-2-1601 and EM 1110-2-2302 provide guidance on the stone properties, characteristics, and gradations specified herein. Cracked Stone Criteria Criteria for a "fractured" or "cracked" stone is: "any stone which contains one "visible" and "continuous" crack or fracture which is exposed on two or more faces of the stone, or any stone which contains two or more visible non-continuous cracks on any one face of stone." A continuous crack or fracture is defined as "an exposed unbroken and uninterrupted visible crack or fracture with a length equal to or greater than one-half the least dimension of the face on which it is exposed". Evaluation of a crack or fracture along a stone face shall only be based upon length and not width (openness) of that crack or fracture. Armor Stone A Stone shall be well graded from 4,000 pounds to 12,000 pounds with fifty percent (50%) of the stone greater than 8,000 pounds. Armor Stone B Stone shall be well graded and from 10,000 pounds to 18,000 pounds with fifty percent (50%) of the stone greater than 14,000 pounds. Armor Stone C Stone shall be well graded and from 16,000 pounds to 24,000 pounds with fifty percent (50%) of the stone greater than 20,000 pounds. NOTE: SEE ATTACHED STONE ACCEPTANCE CRITERIA CHART Freezing & Thawing and Wetting & Drying Stone material shall be subjected to freezing and thawing and wetting and drying testing in accordance with ASTM D 5312 and ASTM D 5313 respectively. Photographs for freezing and thawing and wetting and drying testing shall be taken for each sample tested both before and after testing. Slabs cut for freeze and thawing testing shall have a surface area of 144 square inches on each sawed faced. Any changes observed in the testing specimen including, but not limited to, cracking, spalling, rock popping, or dissolving shall be recorded and photographed at the completion of each test cycle. Petrography Stone material shall be subjected to comprehensive petrographic evaluation in accordance with ASTM C-295. Stone material shall be fresh (no signs of weathering), with interlocking crystalline structure, and free of material such as expansive clays or any detrimental or deleterious features discussed in paragraph 2.1.1, STONE MATERIAL QUALITY. Crystalline structure refers to igneous, metamorphic, or sedimentary rock texture consisting of interlocking, crystalline grains. Matrices of any stone consisting of argillite, sericite, smectite, talc, chloritic, soft material, or highly weathered material shall be identified and noted. Examination shall include description of any seams, veins, or joints and an estimate of alteration, degree of weathering, and probable rock durability. The comprehensive petrographic examination shall also include description of dominant, accessory and alteration minerals. The petrographic examination shall be conducted by a state licensed Professional Geologist specializing in the field of Mineralogy or Petrography. Photographs of stone material examined shall accompany the petrography testing results. Petrography may be completed at a laboratory other than an approved USACE validated commercial testing laboratory; however, certification proving that a state licensed Professional Geologist specializing in the field of Mineralogy or Petrography will be completing this evaluation shall be included in the Evaluation Testing of Stone Submittal for review and approval. Set-Aside Testing (Curing) All Armor Stone gradation classes, dimensioned to final size shall be stockpiled in windrow fashion at the quarry at least 90 days prior to delivery to the project site to insure that unloading type fractures caused by the release of stored energy concentrations will not take place and that natural moisture has time to escape. Individual Armor Stone from each gradation shall be set aside and immediately examined and photographed. The Set-Aside stone should be reexamined monthly by the Stone Material QC Supervisor or SMQCC staff. The Stone Material QC Supervisor shall be responsible for the monthly inspection scheduling, collection of photographs, and maintaining written records of these inspections. Stone that endures without signs of deterioration may be considered for acceptance. A 180 day stockpiling for case hardening purposes shall be required if any sandstones are used. Curing requirements may be waived or reduced by the Contracting Officer if records, documents, and /or other evidence is submitted by the Contractor which conclusively supports such a change. Size and Shape Stone delivered under this requirement shall be blocky in shape with sharp angular edges with its greatest dimension not greater than three times its least dimension (3:1 ratio). The term blocky shall be understood to mean cuboidal (roughly cubical in shape). The term angular shall be understood to mean that the blocky stone shall have sharp, clean, angular to sub-angular edges at the intersections of relatively flat faces. All other stone shapes, such as wedges and/or pyramids, or stones having a triangular and/or pyramidal cross-section, will be rejected. All boulders and parts of boulders will be rejected, with a boulder being defined as any rounded stone not having sharp, clean, angular to sub-angular edges. Dimension and Volume Once a stone meets the shape requirements set forth in paragraph, SIZE AND SHAPE, that stone's dimensions shall then be evaluated to determine if the stone is a slab, flat, elongated, or flat and elongated. In accordance with The Rock Manual, a total of five (5) dimensions are required to qualify the stone shape: L (maximum length), D (minimum distance), and the X (maximum or length), Y (intermediate or width) and Z (minimum or thickness) rectangular dimensions (see Appendix A). The maximum length of a stone (L) shall be defined as the maximum distance that can be obtained between two (2) parallel lines by placing and rotating the stone, in all directions, between the lines while having the stone "touch" both lines. The minimum distance, D, shall be defined as the minimum distance that can be obtained by the procedure outlined above. The evaluation of the X, Y and Z rectangular dimensions shall be performed by enclosing the stone piece in a hypothetical box (i.e., an imaginary, six-sided, three-dimensional space with parallel opposing faces intersecting at 90-degree angles). In accordance with Appendix A, each stone shall have a blockiness factor, BLc, greater than 55%. In addition, the length to thickness ratio, LT, for each stone shall be no greater than 3:1. All flat stones, elongated stones, flat and elongated stones, and slabs not meeting these requirements will be rejected. It is important to note that in order to meet the size and shape criteria, modification and processing of individual stones may be required. Prior to shipment, a USACE representative at the stone source will make the final determination as to whether or not each stone meets the size and shape requirements specified herein. All stone deemed unacceptable shall be set aside and will not be used for this contract. Firm's response to this request for information notice shall be limited to 3 pages and shall include the following information: 1. Firm's name, address, point of contact, phone number, website, and email address. 2. Firm's capability to produce the required stone including production rate and lead time from date requested. 3. Firm's recommended form of transport of rock to the project site. All responses to this request for information notice will be evaluated and used in determining acquisition strategy. DO NOT SUBMIT PROPRIETARY AND/OR BUSINESS CONFIDENTIAL DATA. Submission Instructions: Interested parties who consider themselves qualified to perform the above-listed project are invited to submit a response to this request for information notice by no later than 02 November 2018 by 2:00PM Local Time. All responses under this request for information notice must be emailed to tonya.m.rogers@usace.army.mil. Prior Government contract work is not required for submitting a response under this request for information notice.
