When should windows, roof trusses, joinery and other long-lead items be ordered?

Use the construction programme and current supplier information to plan orders. Record who orders each item, the required design or selection approvals and the expected delivery date. Check access, lifting, storage and protection arrangements. Before substituting a product, assess design compliance, price and timing and obtain any required approval or contract variation. Ask each supplier to confirm its lead time for your order rather than relying on a general ordering timetable.
