Every time that I have to monitoring tendons with tendon system, For bid podium or slab , this company always send just 2 people with 1 machine!! And goes super slow then take lot of time and some times 2 days!!! to finish whole slab and I have to charge my client lot.
I don't know why this company don't send more people with one more machine??
I don't have problems with another company they always have more than 2 people to help and finishing soon.
