CHATTANOOGA (WRCB) - A local family will be surprised Sunday morning. We do not want to reveal the location or the family until the surprise happens. 

Builders are putting finishing touches on their plans, the network has an army of production staff members, local volunteers are waiting on their instructions, and a lot of Channel 3 viewers just want go see one family's dream come true.

So here's what you need to know:

Channel 3 has confirmed the family will be surprised sometime in the first half of the day on Sunday. The location will remain a secret until the surprise can happen and the film crew from Los Angeles can get the shots they need for the Extreme Makeover: Home Edition show. The location will be revealed to the volunteers and our viewers on Sunday. After the family completes the initial filming inside their current house, Channel 3 will be able to interview them before they leave on their big trip. The family's current house will be boxed up and keepsakes preserved to prepare for Monday's demolition.

Monday will be demolition day. Spectators will not be allowed on site Sunday during the surprise or on Monday because of safety and security concerns with demolition. The show's host, Ty Pennington, will be in the area for the beginning. At some point in the week he will leave but will return to see the conclusion of the project and welcome the family home.

On Tuesday, spectators will be allowed to gather in a designated area. Cameras are welcome. However, do not expect to get too close to the house unless you are assigned to work on it. No cameras, even by volunteers, will be allowed inside the house.

Chief Meteorologist Paul Barys expects perfect weather for the build week. However, the show organizers ask you to wear long sleeves, long pants, no shoes with open toes. Even spectators could be asked to help volunteer so be safely dressed for a construction zone.

Since the construction and production crews will need to take over a major part of a local neighborhood for a week, families will be offered other accommodations if they prefer to stay away during build week.

The neighborhood will have some space limitations because of the 30+ production vehicles and trucks that will need to park. Spectators and volunteers will be asked to arrive via free shuttle from a nearby parking lot. Information about that will be released on Sunday.

A catering tent will be set up for volunteers. Local food vendors are volunteering time and food to keep everyone who's working on the site well-fed. Spectators will not have access to the catering tent.

Channel 3 Eyewitness News will have a full team on site each day. Cindy Sexton, David Carroll, Paul Barys, and other members of our team will be on site. Come say hello!
