The Mountain Wolves snapped a four-match winless streak to sink struggling side Olympic on Friday, thanks to a brace from Reda Al-Weeshi and a goal from Khaled Yosri.
The victory eased the crisis of Contractors, who had been without a win since beating Telecom Egypt in November.
They moved into eighth place with 21 points, three above the relegation zone.
"We were eager to claim the most valuable three points and we succeeded in doing that," Radwan told the post-match press conference.
"I'm satisfied with the players' display tonight, they played very good."
Contractors will be hoping to build on that victory when they face defending champions Ahli in their next league game.
"It will be a very tough game against Ahli, but we will try to achieve the best possible result," Radwan added.
