Wingard Analysis Software & Design Layups (WET) Solicita�on #19AQMM24R0106

Amendment 0002 Ques�on and Answers

1. ANFO Characteriza�on: DOS to advise if measurement data for the fuel/oxidizer and water content of the ANFO material is required for this SOW and associated methods, standards, and specifica�ons to follow- if needed. Response: Yes. The offeror is to propose method of analysis.

2. Glazing Layup Parameters: For Test Matrix 1: Per SOW, the Glazing Layup designs for the test specimens will need to be generated based on the performance requirements noted in the SOW. The SOW, however, did not provide guidance on preliminary blast-resistant glazing layups for budge�ng considera�ons. The offeror requests DOS to provide preliminary layup guidance based on historical data on blast-resistant layups u�lized in OBO installa�ons or layups tested in previous programs. Response: The SOW includes the requirement for the offeror to design the windows based on the blast loading discussed. Previous test/data will not be shared at this �me. As discussed in Task1.A, the offeror is to develop glazing layups for aspect ra�os, sizes, and glazing types using WINGARD so�ware for all Rectangular and Irregular Shaped Windows. The included glazing layups and test matrix are just examples, as �tled.

3. For Test Matrix 2: Per SOW, the Glazing Layup design cost es�mates will be based on the provided FE/BBR layups provided in the SOW. DOS to confirm. Response: The SOW includes the requirement for the offeror to design the windows based on the blast loading discussed. As discussed in Task1.A, the offeror is to develop glazing layups for aspect ra�os, sizes, and glazing types using WINGARD so�ware for all Rectangular and Irregular Shaped Windows. Also per, Task 2.A: Develop the test matrix. The included glazing layups and test matrix are just examples, as �tled.

4. For Test Matrix 3: Triangular Glazing layups will assume similar layup configura�ons for Test Matrix 1 for budge�ng and planning purposes. DOS to confirm. Response: The SOW includes the requirement for the offeror to design the windows based on the blast loading discussed. The included . As discussed in Task1.A, the offeror is to develop glazing layups for aspect ra�os, sizes, and glazing types using WINGARD so�ware for all Rectangular and Irregular Shaped Windows. Also per, Task 2.A: Develop the test matrix. The included glazing layups and test matrix are just examples, as �tled.

5. For all the glazing layups proposed for the SOW, glazing sub-framing applicable for commercial applica�ons is excluded. The glazing layups will be procured from the vendors, delivered to the blast test site, to be mounted within rigid steel framing inserts that accommodate the bite depth requirements, and integrated in the front face rigid fixturing of the reac�on structure. DOS to confirm. Response: The SOW is correct.

6. Fixturing and Instrumenta�on Parameters: Exterior High-Speed Cameras: The SOW generally notes need for high-speed camera. The offeror recommends inclusion of 2 Exterior High-Speed Cameras per blast shot to capture the detona�on event from its source to the front face with the mounted test specimen(s). The footage could also be processed to capture and/or validate blast wave parameters, SBU - CONTRACTING AND ACQUISITIONS as needed. DOS to confirm this is acceptable. Response: Recommenda�ons included in the offeror's proposal shall be reviewed and evaluated.

7. Measurement Parameters: The SOW men�ons measurement of the �me of arrival of the blast wave but does not men�on what this is rela�ve to. Is this rela�ve to the ini�a�on of detona�on, detona�on of the booster, or detona�on of the full charge? DOS to confirm. Response: Ini�a�on of detona�on.
