Dress the Builder
Divide the kids into two teams and have them select one team member to dress. Give each team a T-shirt, a flannel shirt, jeans, socks, work gloves, goggles, tool belt and tools. The first team to dress the person wins the game! Another variation of this game is to have each team take a roll of caution tape and wrap it around one kid until he's completely covered. First team to finish wins.
Pin the Tools on Bob
This is just like Pin the tail on the Donkey. Get a poster of Bob the Builder and create a few cardboard tools for the kids to pin on while blindfolded.
Here's a cool variation on one of the classic party game ideas: Simon Says. The birthday kid should wear a construction helmet and can be the one to call out the commands. The kid says "Foreman Says" and the guests do as they are told. Some command examples are: dig with a shovel, mix cement, drive a truck, hammer a nail, etc. If the birthday kid doesn't say "Foreman Says" the guests stay still. Those who do move are out. Play continues until only one contestant remains and is declared the winner.
Bob's Rock Toss
A fun construction kid party game idea is to make "rock" bean bags from old grey socks (fill them up with beans or rice, and sow them closed or use a rubber band). Use a couple of Tonka dump trucks and have the kids try to toss their "rocks" into the dump truck.
Find Bob's Phone - Birthday Party Hunt
Before the party begins, hide a bunch of toy cell phones (which you can find at candy stores with candy in them). Gather all of the kids together, have a phone ring in your pocket, and then say "Oh no, Bob the Builder has lost his cell phone again and it's ringing!!" Then give the kids five to ten minutes to run around the party area and search for the phones. Make sure everyone gets a phone in the end.
Dirt Pile Play
You don't always need to come up with complicated party game ideas. Kids love just playing in the dirt. Fill up a kiddie pool or sandbox with dirt and give them all kinds of construction vehicles, small shovels, buckets, etc. to play with. Another cool idea is to hide a number of miniature construction toys to resemble Bob's machine friends in the dirt and have the kids dig for them.
Roley the Steamroller's Relay
Divide the group of kids into two teams. Within each team, group the children in pairs (if there is an odd number of kids, have one group of three). Make a start and finish line for each team and mark it off with caution tape. Have each team stand in a line, while the pairs are standing next to each other. Then have the first kid from each pair cross his/her arms across the chest and lie down on the ground (this kid is going to be the "rollee"). The other kid from the pair rolls his/her partner to the finish line. Once they reach the finish line, the next pair should be ready to roll. As prizes, you can give steamroller trucks.
Wheel Barrow Races
Divide the group of kids into two equal teams and have each standing in a single file line one after the other. Then tell the first kid in each line to get on their hands and knees. To start the game, the second player of each line grabs the first kid's ankles and holds up their legs (so that they can walk on their hands). Then have them race to a designated area and reverse back. Continue this until the first team to finish wins.
Put a large amount of cotton balls in a large bowl. Then blindfold two players and have them scoop the cotton balls from one bowl to the other using a small plastic shovel (within a time limit). When the time is up, count the cotton balls and the one with the most cotton balls wins.
Wendy's Clean-Up Relay
Divide the group of kids into two teams. Line them up on one side of a large play area and place buckets on the other side of the play area. Then, for each team place a claw toy (the kind where you squeeze the handle to open the claw on the other end) and an equal number of blocks right by the buckets. To start the game, the first person on each team runs as fast as they can to their team's blocks and uses the claw to pick one block up and put it in the bucket. When they finish, they return to their team and tag the next kid who continues doing the same thing. The first team to finish is the winning team.
Scoop's Scooping Game
Divide your group into two equal teams. Give each team a bucket, bowl, or dump truck. Then give each person of every team a spoon and a pile of sand. Have each team sit around the bucket, and when you say "go" each team has to try and fill their bucket with sand using only their spoons. The team to fill their bucket first wins.
