| 3 | 1/23/24 | Mike Cashman, Plant Construction Company | The geotechnical report recommends proof testing to 150% of design load. The specifications indicate testing to 100% of design load. Please clarify what the test load will be. Geotech paragraph 3.2 vs. Spec. Section 31 63 33 | Specification 31 63 33 - Drilled Micropiles will be followed for proof testing of micropiles. Please be advised that the test load provided in Section 3.4.C.4 will be modified in an addendum so that the "Maximum Test Load = 150 kips". |
| Additionally, 03 30 00, under section 2.4, micropile reinforcing will be modified in an addendum from "ASTM A615, Grade 60" to "ASTM A615, Grade 75". | WJE | 4 | |||||
| 5 | 1/23/24 | Mike Cashman, Plant Construction Company | The project specifications have provisions for steel casing. The project plans do not indicate casing.

| 6 | 1/23/24 | Mike Cashman, Plant Construction Company | If steel casing is required, what is the maximum casing OD allowed for this installation? Spec Section 31 63 33 | Steel casing is not needed from a geotechnical standpoint. | WJE | 4 | |
| 9 | 1/23/24 | Mike Cashman, Plant Construction Company | Please clarify the emergency egress plan for the Phase 3A Basement work as drawing G007 only shows an emergency egress path from the First Floor and which is not accessible from the Basement level.

| 11 | 1/23/24 | Mike Cashman, Plant Construction Company | Please clarify the symbols at the wall elevations (similar to sheet A360 at grid K.3): symbols are 920-PLp0 & 901-BF or 901-SM at wall? What does the 0 mean after the PLp symbol? Are these symbols the existing conditions of the walls? Sheet A360 | The "O/" is provided in the definitions on Sheet G003 and is defined as "over". For example, 920-PLp O/ 901-BF OR 901-SM reads: direct applied plaster over board-formed concrete finish or smooth concrete finish. |
| These symbols represent the finishes after the new concrete is placed. | WJE | 4 | |||||

If so, please advise to the location we should assume. | Yes, a batch plant for this project is required, see section 01 27 00 paragraph 3.1. A permissable location for the batch plant may be at "Barbershop Plaza" in staging area 6A on drawing G005. See contract documents for additional details on staging areas or other limitations. | NPS | 4 |
