The freight elevator sets your schedule, not your seat count
Facilities teams usually open a move conversation with a seat count. It is the wrong first number. Two hundred and ten seats in a building with two freight cars and a 24-hour dock is a different project from 210 seats in a 1980s tower with one car, a four-hour minimum after-hours block and a building engineer charged by the hour.
The elevator is the throughput constraint on almost every tower move in Houston. Everything else, crew size, truck count, even the number of weekends, is derived from it.
Work out the cycle time
A freight car cycle is load, travel, unload, return. In a 30-storey tower with a car that takes six panel carts, a realistic cycle to a mid-level floor is eight to twelve minutes once you allow for door hold, the walk to the suite and a shared lobby. Call it ten. That is six cycles an hour, 36 carts, in a four-hour block, around 144 carts.
Now count what you have to move. At roughly four to six crates per workstation plus furniture, a 210-seat floor is well over a thousand crate movements before a single desk leaves the floor. The arithmetic decides the schedule long before anyone discusses how many movers to send.
More movers does not beat one elevator
This is the most common and most expensive misunderstanding in office moving. If the elevator can move 36 carts an hour, a crew of 24 will not move more than a crew of 14; it will simply stand in a queue at a higher hourly rate.
The right crew size is the one that keeps the car full on every cycle and no more. Extra hands go where the elevator is not the constraint: dismantling furniture, staging by zone at origin, or building workstations at destination while the car is running the other direction.
Book the car before you book anything else
Downtown Houston towers are routinely reserved four to six weeks ahead, longer in the lease-turnover months. Uptown mixed-use buildings share docks with retail deliveries and allocate slots by the hour. The Energy Corridor and Sugar Land are far more forgiving, which is why weekday windows are often viable there and never downtown.
When you book, get three things in writing: the exact hours of the block, whether a building engineer must be present and at what hourly rate, and whether the car is exclusive or shared with other tenants during the window. A shared car during business hours adds 20 to 35 percent to the clock, and it is much cheaper to know that at quote stage.
When the answer is more weekends
Sometimes the cycle time maths says a single weekend is not achievable, and no amount of crew will change it. That is a scheduling answer, not a pricing one: phase the move by floor or by department across two or three weekends, keep the business operating throughout, and accept a longer overall programme in exchange for a working Monday each time.
We would rather tell a client in week one that their move needs two weekends than discover it at 3 am on a Saturday with a queue of loaded carts on level 19. The elevator is a fact. Plans are negotiable.
