A Gate Installation Day Hour by Hour
A gate installation day in Georgetown, TX runs about eight to ten hours for a single swing gate and longer for a dual swing pair or a slide gate. The work follows a fixed order, because each step depends on the one before it. Posts cannot be set until the opening is marked, the leaf cannot be hung until the concrete has cured, and the latch cannot be aligned until the hinges are true. A crew that keeps to the order finishes on time, and a crew that skips a step spends the next day undoing it.
What does the crew do first thing in the morning?
The first hour is for layout. The crew walks the opening with the drawing, confirms the utility marks, and moves anything that sits in the way of the holes. Stakes go in at the center of each post, and a string line is pulled across the opening at the height of the top rail. The width between posts is measured at the top, the middle and the ground, and the numbers are compared with the shop drawing.
This is also the time to settle any change. If the owner has added a curb, resurfaced the drive or moved a sprinkler head since the site visit, the layout changes now. A change at seven in the morning costs a few minutes. The same change after the concrete is poured costs the whole job.
How does the day break down by hour?
The table shows a typical schedule for a single swing gate on a flat lot, with the posts set on the first visit and the leaf hung on a second visit a week later. Slide gates, dual swing pairs and sloped drives take longer at each stage.
| Stage | Typical time | What gets done |
|---|---|---|
| Layout and utility check | 1 hour | Stakes, string line, width at three heights |
| Drilling the holes | 1 to 2 hours | Auger to depth, rock or clay handled |
| Setting posts and conduit | 2 hours | Gravel base, plumb, braces, conduit |
| Pouring concrete | 1 hour | Stiff mix, lifts, rodding, troweled crown |
| Cure wait | About 7 days | Posts braced, top kept damp |
| Hanging the leaf | 2 hours | Lift, shim, hinges, swing test |
| Latch and drop rod | 1 hour | Keeper, play, sleeve, center stop |
| Operator and final checks | 2 to 3 hours | Mount, wire, sensors, reverse test, notes |
What happens when the holes are drilled?
An auger rig drills each hole to the depth on the plan, usually thirty to thirty-six inches for a single leaf and deeper for a heavy pair. In western Williamson County the auger often meets limestone soil and then solid rock, and the crew changes to a rock bit or drills a shallower hole that is pinned with epoxy. East of Interstate 35 the soil turns to clay, and the crew drills the hole wider at the base so the clay cannot lift the footing.
Spoil is piled on a tarp so the lawn survives, and each hole is cleaned out by hand. A hole with loose dirt in the bottom gives a post that settles after the first rain, so the last few inches are done with a shovel and a tamping bar.
How are posts set, braced and poured?
Each post goes in on a few inches of gravel, and the crew checks it with a level on two faces. Braces of lumber hold the post plumb while the concrete goes in. The hinge post is set first, since it carries the load, and the latch post is then set to the measured width from it.
Concrete is mixed stiff and poured in lifts. A rod or vibrator drives out the air pockets that would otherwise leave voids around the steel. The top is troweled in a crown so water runs away from the post. If a gate opener is planned, the conduit is laid before the pour, with pull string inside so wires can be fed later without digging.
Why does the leaf wait a week?
Concrete reaches most of its strength in the first week. A leaf hung on a green footing puts a twisting load on it, and the post can shift a quarter inch, enough to throw the latch off and make the leaf drag. In cool weather near Lake Georgetown the wait stretches to ten days, and in a July heat wave the top of the footing has to be kept damp so it does not crack. The crew uses the wait to finish the frame and the finish in the shop.
What happens on the second visit?
The leaf arrives on a truck and goes onto blocks. The crew shims it to the clearance on the drawing, marks the hinge positions and fixes the hinges. The pins of the two hinges must stack straight above each other, which the crew confirms with a long level held against them. The leaf is then swung through its arc, slowly, with a hand on the bottom rail to feel for drag.
The latch and keeper come next. The keeper is set to the bolt with a quarter inch of play, so the bolt still catches when the steel grows in summer or shrinks in winter. On a dual swing pair, the drop rod sleeve is set in concrete with a drain, and the center stop is fixed so the leaves meet cleanly.
How is an operator added?
A gate opener is mounted on its own post or pad, with the arm or chain set to the geometry of the leaf. The control box is wired, the limits are set, and the force is adjusted until the gate stops on light contact and still closes against a breeze. Photo eyes are mounted at knee height and aimed across the opening.
The safety reverse is tested with a block of wood in the path. The manual release is thrown with the power off to confirm that the leaf can be moved by hand. Those two tests matter more than any other step, and they are never skipped.
What is checked before the crew leaves?
The last hour is a walk-through. The swing is tested several times, the gaps at the latch are measured top and bottom, and the clearance under the bottom rail is checked at the highest point of the arc. Weld spots and drill marks are touched up with a zinc-rich primer and matching paint, since bare steel starts to rust in humid Central Texas within days.
The crew writes down the clear width, the latch gap, the rail clearance and the operator settings. Those numbers are the baseline for every later service call, and they let a technician tell whether a post has moved or a hinge has worn.
What can stretch the day?
Rock is the most common delay, followed by buried lines that were not on the locate marks, rain that stops the pour and a drive with more slope than the drawing showed. A change in the middle of the day, such as a different latch height or a new post location, also adds time. A clear opening, marked utilities and a firm decision on the design are what keep the day short.
What is the short answer?
A gate installation runs layout, holes, posts, concrete, a week of cure, hanging, latch and operator checks, in that order. Keeping to the order is what makes the gate swing true for twenty years.
