What might seem to them like a reasonable, cost-saving measure to a contractor—e.g., installing a t-junction in place of a y-junction or using a standard excavator in place of a mini-excavator—can lead to sub-optimal performance or even failure. A clear tender with the necessary construction notes should avoid these sorts of problems.

======Minimum contractor requirements======
Many contractors are unfamiliar with building LID practices. Whether an open or invited bid, minimum contractor requirements can be established in order to provide a project bid. Contractor training, attendance of pre-bid meetings, LID project references and bid bond insurance can form minimum contractor requirements.

The project contract and tendered drawings, including details, notes, ESC requirements, material specifications, and testing requirements should align. Given that most standard contract templates do not include wording specific to LID construction, considerations for LID can be placed under special provisions within the contract.

Details within the drawings and contract should also be accurately reflected in the tender bid form. A detailed bid form that reflects the entirety of the work allows contractors to deliver accurate bids, lessens the likelihood of project shortcuts, and helps to ensure transparency amongst bids. Ultimately, clear bid pricing reduces the potential for misunderstandings and conflicts and attracts experienced contractors.

Minimum contractor requirements[edit]

Many contractors are unfamiliar with building LID practices, so project managers should consider minimum contractor requirements. Consider mandating contractor training, attendance at pre-bid meetings, LID project references, and bid bond insurance as prerequisites.

Low Impact Development. A stormwater management strategy that seeks to mitigate the impacts of increased urban runoff and stormwater pollution by managing it as close to its source as possible. It comprises a set of site design approaches and small scale stormwater management practices that promote the use of natural systems for infiltration and evapotranspiration, and rainwater harvesting.
