Sturdy 6-inch Concrete Parking Slab

As an individual who prioritizes quality and durability, I require a well-constructed 16ft x 40ft reinforced concrete slab for my parking lot over the basement. It must have a thickness of 6 inches to sufficiently bear the weight of medium-sized vehicles like vans and small trucks. Suitable applicants for this project should have significant experience with concrete work, specifically formulating and pouring slabs for medium-scale vehicular loads. Mastery in ensuring proper slab thickness and reinforcement is key. Ability to work within a given timeframe while maintaining attention to detail will be highly appreciated.
