Visit the intended project site before submitting the tender bid.
By doing this you can spot potential problems that may not have been documented.
Do not do a cost proposal with an incomplete review of the site and conditions.
Don’t submit the cost proposal until you have been given access to all areas of the relevant project site.
If you are given a project that has already been won, visit the site personally to familiarize yourself with it. Don’t write a plan to perform the services until you have visited the site.
