Ask a bridge contractor what delays a river crossing and the answer is rarely steel or cement. It is the week the stressing supervisor is on another site, or the cofferdam gang walks off before the floods. This post lists what to set up first, in the order that protects the programme.
Start with the people who hold the critical path
A bridge job runs on a few activities: well sinking or pile boring, pier shuttering, pier cap casting, bearing seating, girder launching, post-tensioning and the deck pour. Each has a small gang that cannot be swapped at short notice. A pot-PTFE bearing fitter or a jack operator for the stressing rig may be the only person in the company who has done it.
- Write the gang for each activity on one sheet: lead hand, riggers, signalmen, crane and winch operators, bar benders, shuttering carpenters.
- Mark who is a single point of failure, such as the only certified stressing supervisor.
- Note the next commitment of each key gang, so a slipped launch does not collide with the next site.
- Name the outside reserve, for example a rigging contractor you have used before, with the days of notice they need.
Keep this sheet in the project manager's office, not in the head of the site agent. The competency and talent management page for bridge firms shows a fuller form.
Pre-pour readiness is an HR check too
A deck slab or pier cap pour is signed off by the QA engineer on a pour card. Add a people line to that card. Concrete does not wait for a tired finishing gang, and a cold joint at three in the morning costs weeks of chipping and repair.
- 1
Confirm the relay
Vibrator men, finishers and the batching plant operator each have a named relief and a handover time.
- 2
Confirm food and water
Tea, a hot meal and drinking water are budgeted for the whole pour, including the night.
- 3
Confirm the medical cover
A first aider is on the deck and a vehicle is parked for the nearest hospital.
- 4
Confirm the stop rule
The shift engineer knows who may halt placement if transit mixers stop arriving or lightning moves in.
- 5
Confirm rest and pay afterwards
Next-day rest and the night allowance are agreed before the pour, not argued about afterwards.
Height, water and traffic need a daily fitness call
Pier work above a river, launching over a live rail line or fixing expansion joints beside moving traffic leave no margin. Before each shift, the supervisor checks harness, lifeline, tool tether and life jacket, and asks each person how they are. A man who has not slept, or who is unwell, stays on the ground. The foreman must know the project manager will back him. See workplace health and safety for routines you can adapt.
Seasons decide the hiring calendar
Bridge sites over rivers work to the monsoon. Foundations and pier work crowd into the dry months, then the river rises and girders wait. Casual gangs of well divers, cofferdam builders and bar benders drift to other jobs when the site goes quiet. Keep a list of the people you want back in October, with their villages and phone numbers, and call them before the water drops.
Pay terms for night work and remote sites
Gangs on a river bank live in labour camps and travel far from home. Write down the daily rate, the overtime rule for night pours, the advance policy and the day of payment. Post a copy in the local language at the camp gate. Most disputes on bridge sites begin with an advance nobody wrote down.
Capture what the foreman knows
A launching foreman reads the nose of a girder as it lands. He knows how bearings seat on a cold morning and how to talk a crane operator through a tight swing. None of it is on a drawing. After each major activity, sit him down with the site engineer for half an hour. Record what worked, what failed and what he would change. File the note where the next site can find it.
Handing over a site engineer
Engineers rotate between stretches or leave for larger firms. Each exit takes the hold points, the client's quirks and the open drawing revisions with it. Ask for a two-page handover note: sequence, pending RFIs, third-party contacts, material orders in transit. The learning and development page shows how to pass this on.
Where to start this month
Do not build everything at once. Draw up the gang sheet for the next critical activity. Add the people line to the pour card. Agree the fitness call with the safety officer. Then read the bridge contractors page and the wider infrastructure and engineering hub for the rest of the set. If you want help designing it, share your requirements.
