Questions & Answers / Clarifications

This document provides responses to contractor questions regarding the INDE Irrigation Maintenance opportunity (Contract Number 140P4226Q0024).

• Number of Irrigation Systems and Zones: The government has a total of 14 irrigation systems, all with multiple zones. The number of irrigation heads is too numerous to count.
• Controller Type: All irrigation controllers must be operated directly from the timer; no smart controllers or remote access capabilities are required.
• Weekly Inspection Requirements: For the first 1-1.5 weeks, the contractor will inspect every zone on each system to identify defects (e.g., broken heads, malfunctioning valves). Findings will be documented, and upon government approval of material costs, the contractor will perform repairs within a few days of the Notice to Proceed.
• Irrigation Maps and Locations: Maps and locations for devices, controllers, points of connection, and winterization points will be provided to the awarded contractor.
• Backflow Certifications/Testing: The contractor is not responsible for backflow certifications or testing; this is being handled under a separate contract. The contractor is only responsible for ensuring the backflow device is providing water.
• Backflow Device Removal/Reinstallation: The contractor is not responsible for removing or reinstalling backflow devices during seasonal winterization or startup.
• Previous Contract Award Amount/Incumbent: Not applicable, as this is the park's first irrigation contract.
• Repair Labor Costs: Repair labor costs are covered by the contract itself, not the annual Not-to-Exceed (NTE) limit, which applies only to materials.

Questions & Answers / Clarifications

This document provides clarifications and answers to vendor questions regarding the INDE Irrigation Maintenance opportunity (Contract Number 140P4226Q0024).

• Inspection Frequency: The initial question regarding weekly inspections during the winterized/off-season has been clarified. The intended frequency is 26 visits annually (bi-weekly), not weekly.
• Annual Material Ceiling: The annual material ceiling of $2,500 was a typo. The correct figure is a monthly cost of $2,500, resulting in an annual ceiling of $12,500. Bidders should clarify if repair needs exceeding this limit should be deferred or if inspections/reporting should continue.
• Repair Approval Process: For repair work requiring prior approval, a repair time of one to two weeks is considered acceptable, especially when considering the need to inspect other park areas. The process for COR authorization is not explicitly detailed but is expected to minimize delays.
• System Documentation: As-built drawings and system maps are not currently available. The government will check with their design and construction team, and if found, they will be posted as an amendment.
• System Verification: The presence of irrigation systems at all listed locations can be verified on the day of the scheduled walkthrough.
