NETWORK ANALYSIS SCHEDULES (NAS), section

1.10.1.10.1 Cost Loading Activities states that "The value

of commissioning, testing and closeout WBS section may not be less than 10 percent of the total costs for procurement and construction activities." This is an excessive percentage of costs that could reasonably be assumed to be retainage if applied incorrectly, which is not allowed. For instance, true costs of Cx and TAB is closer to 1-3% of most contract values but is this section is misapplied to just those activities routinely. Will this item be enforced and if so what activities are allowed to be added into the schedule to account for the 10%? For instance if sums can be allocated to certain submittals, periodic inspections, 3rd party testing and inspections, etc. These costs could be spread throughout the duration of the project via dedicated activities at the end.

However, if 10% is pushed to the Cx phase of the project or the last 10-15% in the schedule, this is a major issue for cash flow on a project and certain administrators view

Delete “submittals, periodic inspections”, ADD ‘’FINAL” 3rd party testing and inspections, etc."… The intent of this spec language is to provide for adequate documentation that completed work in place is in compliance with the contract. Cx occurs throughout the Design and Construction and Post-Construction, so activities listed shall not include submittals because they do not represent work in place.

Government pays for accepted work in place. Commissioning and testing can occur at any time after the contractor submits all Certificates of Readiness for a system category and are approved by the government. 10 percent spread across commissioning, testing, and closeout WBS may encompass a large number this item as such. Essentially this is gray area and can lead to improper interpretation and usage.

Please confirm that the Mechanical Yard shown in detail A1/A171 does not require a chain link roof cap.

Main mechanical yard shown on A1/A171 WILL NOT have chain link roof cap. Chain link roof cap will only be at mini-split yards at grid lines B and M.

A-132, A- 136, A-202

Drawing A-202 detail A4 shows an elevation with what appears to be a type L4 louver (from A-6) but has no callout number on A-202. This area is located on the second floor at areas 2A and 2F. On drawings A-132 and A-136 this same area shows the louver to be a type L3 louver. Please confirm if these louvers are to be a L3 or L4 louver.

Drawing A-132 and A-136 should be louver type 4. Elevation A4/A-202 does show louver type 4.

G-110, A- 710, A-740, A-741, 07 81 00

Drawing G-110 (Life Safety Notes) and specification section 07 81 00 (Spray Applied Fireproofing), conflict on the fire rating of the building and if spray applied fireproofing is or is not required. Drawing G-110 lists the primary structural frame, bearing walls, nonbearing walls, floor construction and roof construction to be 0 Hour rated and that additional will not be required for the exit stairs and elevator shafts. While specification section 07 81 00 lists the columns, floor decks and floor supports to be 1 HR rated. Through searching the drawings, the only request for fireproofing is on drawings A-710, A-740, & A-741where a note is requesting spray fireproofing on the underside of the deck in rooms 1GS1, 1CE1, 1CE2, & 1FE3. The beams and any columns do not appear to have applied fireproofing in these locations and Drawings A-710, A-740, & A-741 contradicts with the notes on G-110. Please confirm if spray applied fireproofing is or is not required. If spray applied fireproofing is required please confirm that it is for rooms 1GS1, 1CE1, 1CE2, & 1FE3 only and only at the underside of the decking above said rooms.

The spray applied fireproofing is required to create a 1-hour fire resistance rated lid for the stairway and elevator shafts only.

G-110 indicates structural element rating requirements for the building as Type IIB construction. G-110 also states additional fireproofing will not be required to meet NFPA 101 Section 8.2.3.3 which is in regard to the structure supporting the shaft fire barriers.

The fireproofing specified is required to create a lid for the stair and elevator shafts since the shaft fire barriers are not continuous from the bottom of the building to the roof.

NFPA 101 Section 8.6.4.1 permits the shaft to terminate where the highest level of the shaft has constructed with construction meeting the hourly rating of the shaft (1-hour in this case.

As stated in Spec Section 07 81 00 Para. 1.2.1, the spray-applied fireproofing spec is intended to apply to spraying all of the elements of a steel floor portion within rooms where indicated on the drawings

(creating a rated lid for the stairway and elevator shafts).

Will provide section 074213 with Amendment.

A-600, A- 601, A-602, and A-603

The door schedules on drawings A-600 through A-603 do not mention if any of the doors are to be STC rated.

Several of the wall types listed in drawings A-550 Through A-553 list STC ratings up to STC 55. A Solid core wood door assembly normally provides approximately a STC 25 rating and with the seal packages called for in the door schedule would be STC 32 rated. Please confirm that no STC ratings are required for all of the doors per the door schedules (drawings A-600, A-601, A-602, and A-603).

Provide solid wood doors and gasketing as prescibed.

A550, MH161,

MH162

Several of the second floor drawings have a keynote detail with (listed rooms) requiring envelope sealing and pressure testing as outlined in MH161 & MH162. These rooms appear to be surrounded by variants of the wall type #2. Drawings MH161 & MH162 detail how to seal penetrations and cracks, but have no mention if the walls for these rooms will need an air/vapor barrier to be installed or if paint is sufficient for the testing requirements. Please confirm that the paint on the gypsum per wall type #2 on drawing A-550 will be sufficient for the seal and pressure testing of rooms 2C01, 2C02, 2C05, 2C06, 2C08, 2D01, 2D02, 2D03, 2H10, 2H16, 2H17, 2J05, 2J06, 2J10, 2J11, & 2K04.

Paint is acceptable for all interior wall types for testing purposes.

However, all portions of rooms (Eg.

2L01) with exterior walls must be provided with air barriers per plans and specifications.

A-002 Drawing A-002 shows the continuous air barrier around the whole perimeter of the building but has the word “Tested” in each area (1A-1L and 2A-2L). Please confirm that only the full building air barrier envelope is to receive pressure testing and that it is not required to test each individual area.

The whole building will be pressure tested as stated on A-002. Air barrier testing is for the whole building as defined on A-002. In addition there are testing requirements for individual rooms/suites based on sheets MH161 & MH162.

A-610, A- 611, A-612, A-613, A-

The Door frame details in drawings A-610 through A-614 do not show the frames in CMU walls to receive either grout or foam insulation. Please confirm that door frames in CMU walls do not require grouting or foam insulation.

Exterior doors in CMU block only fill with foam insulation.

Amendment Required for notation on door schedule.

A-602 Drawing A-602 lists door 2H08 to have a lead frame only for the door. Please confirm that this is correct and a lead lined door leaf is not required for this room.

No lead lined door required.

13 49 10 - 1.3.3

Specification section 13 49 10 paragraph 1.3.3 for X-Ray Shielding calls for materials to be purchased from a single manufacturer. Please consider removing this requirement as multiple different trades will be supplying

Survey Report

Page 5 3 Paragraph reads, "Prior to demolition/renovation activities,, LBP material that is likely to be disturbed or damaged to the extent that significant amounts of lead would be released, must be removed and/or managed and disposed of using approved practices under USEPAs NESHAP, 40 CFR Part 745." 40 CFR Part 745 is the subpart that mandates Lead Based Paint Poisoning in Certain Residential Structures. This regulation does not or appear to apply to this project. Lead-based paint associated with this project is mostly associated with red paint on structural steel components throughout Building 674 and 602. Standard demolition practices consiting of demolishing stuctural or building components with lead-based paint, in place with heavy equipment, as long as 29 CFR 1926.62 is followed. We do not believe the intent is to scrape and remove the 37,9992 SF of red lead-based paint associated with these components. During demolition, the steel components, painted with lead-based paint will be segregated from the building construction debris and sent to recycling yard as lead, is a metal and can be recycled. The question is, "Does the red lead-based paint need to be scraped and removed from the structural steel compoents prior to demolition of the builidng?"

No, the red lead-based paint does not need to be abated. During demolition, the steel components, painted with lead-based paint should be segregated from the building construction debris for disposal or recycling in accordance with state and federal regulations.
