16. FAQ RESOLUTION
======================================================================

FAQ Q1 {
    question_intent:
    "What is grab wagon hire and how does it work?"

    answer_logic:
    A grab wagon is a driver-operated vehicle equipped with a hydraulic
    grab arm. The arm collects accessible piles of material and loads
    them into the wagon for transport away from the site.
}

FAQ Q2 {
    question_intent:
    "What materials can the grab wagon remove?"

    answer_logic:
    The page specifically identifies excavation debris, soil, brick,
    concrete and wood. Other materials require confirmation.
}

FAQ Q3 {
    question_intent:
    "Do I have to load the wagon?"

    answer_logic:
    No manual wagon loading is normally required from the customer
    because the skilled driver operates the hydraulic grab arm.
}

FAQ Q4 {
    question_intent:
    "How much does grab wagon hire cost?"

    answer_logic:
    The page advertises the service from £200. Treat this as a starting
    price rather than a guaranteed quote and confirm the current charge
    with the provider.
}

FAQ Q5 {
    question_intent:
    "Is grab wagon hire available in Withernsea?"

    answer_logic:
    Yes. The page specifically presents grab wagon hire for Withernsea
    and states that Withernsea is within the company's service coverage.
}

FAQ Q6 {
    question_intent:
    "Can a grab wagon remove concrete or patio rubble?"

    answer_logic:
    Yes, concrete is explicitly listed as a material the service can
    handle. Access, quantity and disposal details should be confirmed.
}

FAQ Q7 {
    question_intent:
    "Can the company deliver gravel?"

    answer_logic:
    The page states that the grab truck can support delivery of gravel
    for projects such as driveways. Confirm the required material,
    quantity and delivery access.
}

FAQ Q8 {
    question_intent:
    "What are the main benefits of grab wagon hire?"

    answer_logic:
    It can collect substantial quantities of accessible material quickly
    and reduces the manual work associated with loading a skip.
}

FAQ Q9 {
    question_intent:
    "How do I arrange grab wagon hire?"

    answer_logic:
    Contact East Yorkshire Aggregates & Skips on 01482 450291 or use the
    website contact form with the site, material, access and timing details.
