The star has 1.43 times the mass of our sun and a star's lifetime is inversely proportional to the cube of its mass, so that star's lifetime would only be about a third of the sun's. The sun and the Earth are about the same age, 4 and a half billion years, and in another half a billion years the sun will be too hot for life on Earth. So the sun can provide about 5 billion year window for intelligent life to evolve. On Earth it took 4 billion years to go from chemicals to worms and another half a billion years to go from worms to present day people. The star you're talking about would only have a 1.6 billion year window for life, and that doesn't seem like enough time for Evolution to turn chemicals into Dyson builders . If you were on the Earth when the sun was only 1.6 billion years old you'd have to wait another 2.4 billion years to see the first worm. We only have one example to look at so maybe life on Earth evolved unusually slowly but I think it much more likely that life on Earth evolved unusually rapidly, because Earth not only produced life it produced intelligent life. And however common intelligence is in the universe bacteria must be even more common.
