12. Q: (TC) SECTION 31 23 60 - 5 MECHANICALLY STABILIZED EARTHENSLOPES PART 2.02 MATERIALS SUBPART 1.1The "SI Geosolutions Landlok 120" is not a valid product name. SyntheticIndustries (SI) and Amoco Construction Fabrics and Fibers became one entityseveral years ago and are now called "Propex." In addition, while the "Landlok"product line still exists under the Propex name, the model "120" is no longer astandard product. Furthermore, the "Landlok" product line contains patentedproducts, whose material properties are proprietary and uncompetitive. Pleasecorrect what product(s) you wish to have considered appropriate for this part ofthe Project Specifications.R: Use "North American Green C350 or equal". Refer to Addendum No. 7.13. Q: (TC) SECTION 31 23 60 - 5 MECHANICALLY STABILIZED EARTHENSLOPES PART 2.02 MATERIALS SUBPART J.1, 3"Miradrain 5000" is neither constructed from an AASHTO M288 Class 3nonwoven geotextile, nor from a polyethylene (HDPE) net. It is constructedfrom a slightly lighter weight nonwoven geotextile and a high-impactpolystyrene (HIPS) dimple-board that is perforated to allow cross-planar waterflow. Please clarify its acceptability for this application. Pleas also recommenda suitable HDPE drainage net that is laminated to nonwoven geotextiles thatmeets the mechanical properties listed in the Specification.R: Provide material meeting items 2 and 3 of Section 31 23 60, 2.02, J.Ignore reference made to Mirafi 5000. Refer to Addendum No. 7.14. Q: (TC) SECTION 31 32 19.16-1 GEOTEXTILE PART 1.01 REFERENCESSUBPART A.1.i : A revision to ASTM D4833 was completed last year thatremoved its applicability to geotextile products, though it is still valid for"geomembranes and related products." We suggest that you replace thisreference with the current, more applicable ASTM standard: D6241, "StandardTest Method for the Static Puncture Strength of Geotextiles and Geotextile-Related Products Using a 50-mm Probel."R: Refer to Addendum No. 7.15. Q: (TC) SECTION 31 32 19.16-3 GEOTEXTILE PART 2.01 PRODUCTS; WOVENGEOTEXTILE SUBPART F, Table No. I Is The AOS value in the table,determined in accordance with ASTM D4751, a maximum or minimum rollvalue? Note that this is typically a maximum. Also, in which roll direction is the260 lb (grab) tensile strength to be a minimum value? Machine direction, crossmachine direction or both?R: Maximum roll value. Both directions.16.
