EIFS and Flashing There are conditions where existign roof to wall flashing is sealed to the exterior face of exisiting EIFS wall cladding. This approach of roof/wall flashing relies on a sealant only joint and can potentially result in leaks. Ideally the roof wall flashing would seal to the wall sheathing/ membrane behind the EIFS face. In order to achieve this the EIFS wall cladding would be selectively cut back to allow the new roof/wall flashing to attach the wall membrane, new flashing at the base of the EIFS installed and EIFS patch and repair completed.

Please confirm desired approach.

The Designer of Record is responsible for designing the flashing / roof transition detail between the roof areas. It is expected that on-site inspection and subsequent detailing will be required to confirm the existing conditions necessary to complete this design detail.

CLARIFICATION ON INSULATION THICKNESS/ R VALUE REQUIREMENT

Clarification of Roof Insulation Requirements – Above Deck Assembly RFI Question:

Contract documents state that “existing insulation thickness is acceptable.”

The existing roof assembly appears to consist of a roof membrane with a continuous insulation installed above the roof deck.

PPI Response 10 indicates ASHRAE 90.1 to govern for insulation values.

Please confirm that ASHRAE 90.1 2019 version is applicable as listed in UFC 1- 200-02(JULY 2025), for Climate Zone 4A (Virginia Beach), and roof assembly will have continuous insulation entirely above deck with a minimum of R-30 continuous insulation (ci).

Please also confirm R-30 ci is required for the project, regardless of current insulation value.

It is the intent of this project that the new roof assembly meet the current ASHRAE requirements to the greatest extent feasible. It is NOT intended that the insulation thickness be increased to the extent that parapets require reconstruction and/or rooftop equipment curbs and associated equipment are raised. Consequently, the design must meet the current ASHRAE standards to the extent possible without adversely impacting the existing parapet or flashing installations.

127 5/15/2026 various

CLARIFICATION ON DOWNSPOUT MATERIAL

The RFP stated that flashing, gutters, and downspouts are to be copper and several responses to PPI indicated that the existing flashing, gutters, and downspouts are copper and should be replaced to match earlier project drawings.

However, the existing metal at all locations on the building is stainless steel.

The use of copper in this application would be an unusual application due to the significant costs associated with this metal.

Please reconfirm the preferred use of copper for the project, OR indicate that the replacement of the existing stainless steel flashing, downspouts, and gutters should be with completed with new stainless steel to match sizes and profiles, and with non ferrous fasteners to prevent corrosion.

If stainless steel is selected for use in flashing, downspouts, and gutters, please clarify if 304 or 316 is required. 316 is more corrosion resistant, but has a higher material cost.

The writer of the RFP and PPI responses relied on the material designations from the 2012 roof replacement project in preparation of the documentation used by the government. It is the intent of this project that materials be replaced in-kind.

Consequently, if the existing flashings, counterflashings, downspouts, and gutters are fabricated of materials NOT identifed or specified in the RFP or PPI responses, material substitutions requested by the designer of record will be accepted during the design process.
