Section 00-20-00-2, lines 28 & 38: Add the t, missing from the end of the word Architect

Section 01-15-00 Section number incorrect, should be 01-11-50. See lines 4-6 for engineering requirements of Design-Build.

Section 26-10-00 -Clarification: Existing electrical Service is overhead from across the street to northwest building corner. New service to be underground. Size of service to be determined by Des/Bld Contactor. Equipment consists of a Copier, 2 desk computers, several laptops by visitors and HVAC loads. Lighting layout is shown on Sheet A103, outlets etc on sheet A701

DRAWINGS:

Sheet G103 (Division 8), G105(Schedule) & A102(Plan): Windows Type B, interior, are to be tempered, as required, and insulated glass. No need to be Low-e or have a specific U value.

Sheet G103 (Division 8) Exterior glazing typically is 1/8” Low E with Clear glass. South facing windows are 1/4” Low E with Grey Tinted glass.

Sheet G105 (Schedule), Sheet A102 (Plan), Sheets A201 & A202 (Elevations): Windows Type M, change to unequal split with 1/3 operable sash. Typical head height = 7’-0”

Sheet A002 (Utility notes): The existing service is located on the northwest corner of the existing building via an existing electrical service mast. See bid document (page 217) Section 50-00-00 (Division 33)

Sheet A103 Lighting Layout – See Reflected ceiling plan, City of Yachats Library Bidding & Construction Documents [section 26-10-00 (pages 201-211)] Concept Lobby Lighting spec sheet can be found on page 210. Computer Desks similar to linear concept on example spec sheet. Concept Circulation desk fixture spec sheet can be found on page 209. Sheet A103 is a layout guideline

Clarifications for Electrical:

1. There will be no Parking lot Lighting.

2. There will be no lighting on the pathway.

3. There will be no vehicle charging.

4. See Notes on Sheet A701

5. An exterior wall sconce (downlight) will be at all exterior doors, material to be stainless steel

6. Existing service is 200 Amps

7. No power to future signage

Structural clarification re: Foundation Piers:

1. The helical pier design is based upon the Geotechnical Report (found in the Project Manual) and each pile is limited to 15,000 lbs (allowable load) but the helical pier design itself is by Contractor.

2. The 45-degree battered helical piers shall be designed for 15,000 lb tension and compression. The vertical helical piers next to a holdown shall be assumed to take both tension and compression loads and for now assume 15,000 lbs ASD for bidding purposes, fine tuning can occur of the tension loads as required later in construction. All other helical piers are taking compression loads only.

3. Please note that the site has a significant amount of undocumented fill and the helical piers are intended to be extended below this material and into sound subgrade that is to be determined and approved by Geotech.

4. Substituting to driven pin piles will be something that needs to be run by the geotechnical engineer and may require a redesign by the structural engineer of the grade beam/foundation design to optimize the structure and reduce piles where we can and increasing the grade beam size to span further distances between piles. The contractor will be responsible for any additional design work required.

5. Driven piles can be loud work is to occur during the hours identified in the Local noise ordinance and as specified in the Project Manual.

Note: Addendum No. 2 will be issued 1/7/2025
