How to unlock the Build Buster achievement in Borderlands 2 - Definitive Guide
1. If you're playing with other people you can all shoot the Constructor at the same time and it should die relatively quickly. (This is how I got it, playing with 2 friends and having the Constructor be 2-3 levels above us. We didn't have to much of a problem with it besides maybe having other enemies shooting us at the same time.)
2. You can easily do this by yourself if you have a higher level character. Once you've leveled a lot, load up your character on Normal Mode and you'll be able to kill one within seconds of it appearing.
Constructor Locations:
In Thousand Cuts, a Constructor will appear at the bottom of the Hyperion base, while a Badass Constructor will appear near the top.
In Arid Nexus - Badlands , a Badass Constructor will spawn at the entrance of Hyperion Info Stockade, while two Constructors will spawn at the top once mission Data Mining is ready to turn in.
In Hero's Pass, a Constructor will spawn near the middle of the path, while a drop barge will drop a Badass Constructor near the end, in front of the entrance of Vault of the Warrior.
In Bloodshot Stronghold (side mission - Out of Body Experience), You have to put an AI into different robot body types. Constructor will be the first one. (Thanks to LOUIS 1886 1982 for the information.)
For those of you wondering what a Constructor looks like.

The constructors are large yellow robots with a big red eye in the center, a picture of it is the trophy image. You just need to find one, and kill it quickly. This may be harder at lower levels as the fight with it might take longer, but once you are several levels above it and have some decent powered weapons, you shouldn't have any issues decimating it quickly.
I found I was unable to destroy the Constructor during the mission you free Roland, but was able to get it later in the game when you fight Hyperion enemies in the Highlands.
You can get plenty of Constructor spawns later in the game if you go into the Hyperion circle of slaughter. It's located in Ore Chasm, which is within the Eridium Blight area.
I believe Constructors spawn in around rounds 3-5.
This mission can be obtained a short ways last the entrance of the Bloodshot Stronghold, after you have rescued Roland. Just make sure you're adequately levelled, bring a corrosive gun, and aim for the big red eye. This one shouldn't be too hard.
Something to note is that, although the Constructor will have smaller units and the occasional EXP Loader around it, the achievement is only checking for the bots that it actually digistructs, to my knowledge.
The earliest time you'll come across a Construct is during the side quest "Out of Body Experience". These guys are pretty tough and you may have a few issues in your earlier levels trying to bring one down at your current level and weapons to hand.
There's a little trick though. Once you've come face to face with one, kill all the initial enemies around him and then die. Once you respawn around the corner, the Construct will no longer build anymore robots. This now gives you the time to kill him without the worry of more enemies being spawned by him and missing out on the achievement.
