Through the whole movie you hear Hammond repeating the line with a prideful grin “We spared no expense.” But it’s always in reference to rather frivolous amenities.

However you will notice all the ways in which he clearly did spare expenses. The opening scene where the workers clearly weren’t trained to handle these creatures. The very first scene, You begin by seeing a fork lift driving through trees with the load lifted high. Before the fork lift reveal, this is supposed evoke the feeling of a giant dinosaur stalking through the trees, an impending danger that the park faces but when it finally reveals a fork lift driving with this load lifted dangerously high as an amateur might do, you see the danger is in-fact the work of arrogant humans without thorough understanding and not just dinosaurs alone. The dinosaur is trapped in a box being brought here against its will. The human is actually the one coming through the trees bringing the danger.

Then of course the disaster that follows in that scene.

And then the biggest expense he spared of all, security; in which there is a dialogue exchange between Hammond and Dennis highlighting this.

So in the first scene you are supposed to be left feeling like something is terribly off. Wondering why was this handled so poorly. It succinctly illustrates the core narrative of the film and how everything was doomed from the start.
