Destroy the 4 Coolant Towers, Destroy the Zerg Leviathan.
Demolition Man:
The targeted towers aren't distant and as you have almost a minute to get off the platform, I'm sure you will complete this achievement without even having it in mind.
Speed Too!:
An achievement which can be completed in many various ways, but doesn't necessarily mean it's easy.
The towers are protected by a couple infected platforms. One of them focuses on anti-air defence, the second on ground units. Apart from that, there's a small base nearby you and an all-around base. The suggested solution relies on using air and ground units, but I will also present some more ideas which you can use if you can't make it.
At first you need to build a solid defence, as the Zergs will keep coming from two sides and in high numbers. Build Bunkers, a bunch of Siege Tanks and Vikings. Viking will come in handy against the Brood Lords. In the meantime, make at least two additional Battlecruisers and a Science Vessel (if you have its plans), which will keep repairing the mini-fleet. Invest in a total army as well, building Marines, Diamondbacks and other vehicles, especially focusing on Goliaths - they will play an important role in the south-east Zerg base.
Devastate the nearby tower [1] with the Battlecruisers. You should also destroy the small nest in the west [2]. Even though a couple Battlecruisers would easily handle the base in the upper left corner [3], don't send do it. You can create a road to the tower, but don't destroy it. Damaging them doesn't seem a bad idea, as you'll have an easier task later on, when you return here.
In the meantime, you should create a couple of each vehicle type and infantry. Gather your army and move it together with the Battlecruisers (training some new ones might be a good idea) to the Zerg air base entrance [4]. On your way there, you will bump into some Zergs in the middle part, so look out. Ultimately, begin the invasion.
During the fight, Brood Lords might try to prevent you from accessing the tower, so it would be wise to have Battlecruisers and/or Vikings with you. Don't send them too far however, as there's lots of anti-air devices around. Such units should serve only as support. Goliaths and Marines will deal with the Mutalisks and Corruptors.
After you destroy the platform, the map will be invaded by a Leviathan (it will appear after you destroy each pair of bases), which you probably should leave alone on hard. Even if you do manage to destroy the beast, your forces will be severely decimated, which has no sense. The flying monster will keep an eye on the middle part of the map.
Your ground units however are in a relatively safe place and additionally nearby the lowest base [5]. That will leave you with highest one [3], but some new Battlecruisers should deal with it.
From the destroyed Zerg air base, head towards the next one, remembering that destroying the last one will immediately end the mission. If you want to save some time, destroy the two final ones together.
Another method is building a large fleet of Battlecruisers, as the real targets aren't the bases, but the towers. The anti-air platform is of course a problem here, as it's full of small, suicidal Zergs. You can use the Viking then. There also is a method consisting of building solely Banshees, so it's really up to you.
