12905B24Q0005 Construc�on Two Grape Trellis Systems
Amendment 1
Ques�ons and Answers:
1. Are the bamboo poles for the grape vines to be provided by the contractor? I was informed that there was to be a 30 foot metal pole spacing with several vines between metal posts and that there would be bamboo poles at each vine, between the metal posts.
ANSWER: Iron rebars will be used for each plant loca�on for VAS trellis system in block 11 and 31 and they shall be supplied by the contractor. Bamboo poles will be used in block 12 and 22 ver�cal trellis system, and they will be provided by the government. For both ver�cal and VAS trellis system, the required distance between the highway stakes within a row is 15’. It is industry standard. Increasing the distance between highway stakes within a row will make the system weak.
i. See Attachment VI – V-Trellis System for a drawing of required dimensions of VAS trellis system.
1. Highway stake post length=70”
2. Irriga�on pipe wire height = 20-24”
3. Cordon wire height = 42-46”
4. Length of ver�cal arms = 48”
ii. Plant to plant distance is 6’ and rebar is required for each plant loca�on.
1. Irriga�on wire and cordon wire atached to the rebar is required to further strengthen the system.
2. Length of rebar will depend on the height of cordon wire.
iii. The contractor will need to determine angles of arms as per industry standards.
2. Do the end posts need to be cemented in?
a. ANSWER: No cemented end posts. Industry standard is to use an augur hook of about 3’ to anchor and stabilize the end post and keep hook closer to the end post so it is less of an obstacle for equipment movement. Anchor hook should not be more than 24-30” from end post.
3. Verify the measurements for all cross arms on the GABLE SYSTEM at Block 11 & 31. As discussed on Job Walk, the 48” system noted will not suffice for the system that is being asked for. Please see list below for measurements that require clarifica�on:
a. a. Horizontal Cross Arm – ANSWER: Depends on the angle. Follow industry standards for table grape produc�on.
b. b. Upright Cross Arms (Both Le� and Right) – ANSWER: 48” each
c. c. Total distance between assembled upright cross arms. – ANSWER: Depends on the
Angle, follow industry standards for table grape produc�on.
ANSWER: The contractor is responsible to determine the angles of arms/horizontal cross as per industry standards. Similarly, the length of horizontal cross arm will depend on the angle of upright cross arms. Also, the distance between assembled upright cross arms will depends on the angle. The contractor is responsible to provide the design.
4. Verify loca�ons for wire placement on GABLE SYSTEM at Block 11 & 31.
a. ANSWER: Loca�on of three wires will be also determined by where the contractor places the horizontal cross arm. Wires should be above that as Attachment VI – V-Trellis System suggests. Follow industry standards.
5. Confirm number of wires on GABLE SYSTEM at Block 11 & 31.
a. ANSWER: Three wires, that will be atached to the ver�cal arms at block 11 and 31.
b. One wire for the cordon
c. One wire for the irriga�on pipe.
