Jobsite logistics and site planning field guide
Lay out where material lands, how trucks get in and out, where the crane sits, and how the public stays clear, then update the plan as the building eats the site.
Direct answer
A site logistics plan is the layout and rules for moving people, material, and equipment on and around a jobsite: laydown and staging, access and haul routes, crane and hoist placement, temporary facilities, deliveries, and phasing. On a tight site it matters as much as the schedule, and it changes as the building grows.
Key takeaways
- A site logistics plan is the layout and rules for moving people, material, and equipment on a jobsite: laydown, haul routes, crane placement, facilities, and deliveries.
- Crane capacity falls off as radius grows, so verify rated capacity on the manufacturer's load chart at both the pick radius and the set radius.
- The site shrinks as the building grows, so draw one logistics plan per major phase and update it at every phase transition.
- Call 811 and locate utilities before every dig; the free service marks public lines to the meter, and anything past the meter needs a private locator.
- Separate walking paths from haul roads and crane swing by layout to design out struck-by hazards instead of relying on people to dodge.
What a site logistics plan is, and why a perfect schedule still stalls
A site logistics plan is the layout and the rules for moving people, material, and equipment on and around a jobsite. It says where material lands and gets staged, how trucks get in and out, where the crane or hoist sits and what it can reach, where the trailers and toilets and dumpsters go, when deliveries show up and who receives them, and how the public stays separated from the work. It is the physical half of running a job, and on a tight site it carries as much weight as the schedule.
Here is the failure it prevents. A job can be scheduled to the day, every activity sequenced, every crew assigned, and still grind to a halt because the truck has nowhere to unload, or the lift cannot reach the work, or two trades both need the same patch of dirt on the same morning. The schedule says when. The logistics plan says where and how. Get the when right and the where wrong and the crew stands around while a loaded truck idles at the gate.
This guide covers the where and how. The sequence and timing of the work, the critical path, and the look-ahead the field builds from live in the scheduling guide, and the planning that happens before a shovel hits dirt lives in the preconstruction guide. Logistics is where both of those land on the ground.
Why logistics decides whether the schedule survives contact
A great schedule fails without a place to put things. The schedule assumes material arrives, gets staged near the work, and the crew installs it. Take away the staging and the crew either waits or double-handles, and double-handling is pure cost. Every time a pallet gets moved twice because it landed in the wrong spot, you pay for labor that built nothing.
On an open suburban site you can be sloppy and survive, because there is room to recover from a bad call. On a tight or urban site there is no slack. No laydown means material has to arrive the day it goes in, the crane sits in the one spot that reaches the work or it does not earn its rent, and a truck parked wrong blocks the only gate. The constraint is space, and space is the thing a schedule cannot create.
Then there is the part that does not show up as a delay until someone gets hurt. Logistics is where people and equipment cross paths. A haul road that runs through the crew's walking path, a swing radius that sweeps over an active work area, a delivery that backs into a blind corner: those are the struck-by exposures that the logistics plan exists to design out. The plan is not paperwork. It is how the crew gets a place to work and gets home.
The site logistics plan as a deliverable
The plan is a drawing, not a conversation. A real site logistics plan is a site plan marked up to show where everything lives: the gates and access points, the haul routes and one-way circulation, the laydown and staging zones, the crane and hoist positions with swing and pick radii, the trailers and parking and temporary toilets, the dumpsters, the fencing line, the pedestrian protection, and the no-go areas. Some owners and GCs call it a site utilization plan or a construction logistics plan, and on public work the jurisdiction may require a version of it as a permit condition.
It is a set of drawings, not one drawing, because the site does not stay the same. The common practice is one plan per major phase, each showing the configuration for that stage of the work. The plan also carries rules, not just geometry: delivery windows, who receives material, speed limits on the haul road, the wheel-wash requirement, the hours the crane can swing over a property line.
Build it as a deliverable people can actually read. A plan that lives in one superintendent's head dies the day that superintendent is out sick. The drawing is what lets a new trade, a delivery driver, and an inspector all see the same site the same way, which is the entire point of writing it down instead of pointing at the dirt.
How logistics change as the building eats the site
Logistics are not fixed for the life of a job. They change by phase, and the single most reliable rule is that the site shrinks as the building grows. The space you used for laydown during excavation is under the building by the time you are doing finishes. A plan that is right in month two is wrong in month eight, and a job that plans the logistics once and never revisits it walks into that wall.
The phases drive different needs. During excavation and foundations you have open ground, few trades, and bulk material like rebar, formwork, and aggregate, so you stage near the work and keep the haul routes clear for heavy equipment and dirt trucks. During structure the crane or hoist becomes the constraint and everything orbits its reach. During finishes the building is closed in, the laydown is gone, deliveries move to just-in-time, and vertical transport through the hoist or the building elevators becomes the bottleneck.
Plan the phases as separate problems. Sit down before each major transition and ask what changes: where does material land now, where does the crane go next, how do trucks reach a gate that the new foundation just blocked. The transitions are where logistics break, because the old plan keeps running on habit after the site has stopped matching it.
| Phase | What drives the logistics | Where material lands |
|---|---|---|
| Excavation and foundation | Heavy equipment and dirt haul, open ground | On-site laydown near the work, bulk material |
| Structure | Crane or hoist reach, the pick radius | Staged within the crane's swing, by sequence |
| Enclosure | Tightening site, building footprint claimed | Reduced laydown, more frequent deliveries |
| Finishes and MEP | Vertical transport, closed building | Just-in-time to the floor, little to no storage |
Laydown and staging: where material lands
Laydown is where material is received and held. Staging is where it sits ready to install, near the work. The two get used interchangeably, but the distinction matters: laydown is bulk storage, staging is the last move before the crew picks it up. Material that lands in laydown and then stages near the work moves twice on purpose. Material that lands in the wrong place moves twice by accident, and you pay for both.
Put staging as close to the point of installation as the site allows, and keep it out of the access routes. A pallet of duct staged in the haul road is a pallet that gets moved the first time a concrete truck needs through. Material near the work cuts the travel time the crew burns carrying it, which on a big floor plate is real hours, not minutes.
Space is the constraint, and it is usually less than the plan assumed. Protect what needs protecting from weather and theft, mark the zones on the drawing so trades are not fighting over the same square of slab, and accept that on a tight site the honest answer to where material lands is often nowhere, which is what pushes the job to just-in-time delivery.
What is just-in-time delivery on a construction site?
Just-in-time delivery means material arrives close to when it gets installed instead of being stockpiled on site. On a tight site with no room to store, it stops being a preference and becomes the only option. The duct, the pipe, the drywall shows up the morning it goes in, gets moved straight to the work, and the next delivery does not come until that one is installed.
The trade is real, so call it honestly. Staging on site buys you a buffer: if a truck is late, the crew keeps working off the stockpile. Just-in-time removes that buffer to save the space, which means a late truck now stops the crew cold. It works only when the deliveries are tightly coordinated to the schedule, the supplier is reliable, and someone owns the calendar. On a site with room, hold some buffer. On a site with none, go just-in-time and put real effort into the delivery coordination, because the schedule is now the only thing standing between you and an idle crew.
Just-in-time also cuts the clutter that hurts you in other ways. Less material on site means fewer tripping hazards, fewer stacks to topple, and clearer routes for emergency access. The safety case is part of why it is worth the coordination cost, not just the space.
Access and haul routes: getting trucks in and out
Access is how vehicles enter, move through, and leave the site, and it is where logistics most often seizes up. The plan defines the gates, the haul routes, the circulation pattern, and the unloading zones. The goal a truck should meet is simple: enter, unload, and leave without backing up or making a tight turn it cannot make. A driver forced to reverse blind into a crowded site is the struck-by incident waiting to happen.
One-way circulation beats two-way on a narrow site every time, because two trucks meeting on a single-lane haul road means one backs up the whole length of it. Check the turning radius for the largest vehicle that has to use the route, which is usually the concrete truck, the dirt hauler, or the crane on the day it mobilizes. A gate and a route that work for a pickup do not work for a mixer, and you find that out the hard way when the mixer cannot make the corner with the pour already started.
Mud is the other haul-route killer. A site that tracks mud onto the public street gets a call from the jurisdiction fast, and on many sites a wheel wash or a stabilized construction entrance is a permit condition, not a nicety. Weather turns a dirt haul road into a problem on its own: figure the route in the rain and the snow, not just on the dry day you walked it, because the day you need the route most is usually the worst day for it.
Deliveries: windows, unloading zones, and who receives
Deliveries are where the schedule and the logistics plan meet a truck, and uncoordinated deliveries are how trucks stack up at the gate. The fix is a delivery window: a scheduled time slot for each delivery so two suppliers are not fighting for the same unloading zone at the same hour. On a busy site someone owns the delivery calendar and trades book a slot, the same way you book the crane.
Name the unloading zone and name who receives. A delivery with no assigned spot lands wherever the driver stops, which is usually in the way. A delivery with no one to receive it gets dumped at the gate, signed for by nobody, and the count is wrong before the material ever reaches the work. Decide who checks the load against the ticket, because a short or damaged delivery caught at the truck is a phone call, and the same shortage caught at install is a stalled crew.
On a constrained site the unloading zone may be the public street, and that is a permit. A street occupancy or curb-lane permit from the jurisdiction, often with a flagger and a defined window, is the difference between a legal delivery and a citation that shuts you down. On a building with a loading dock, the dock becomes the constraint and you schedule against its capacity. Either way, the delivery plan is part of the logistics plan, not a separate afterthought.
Crane and hoist placement: reach, pick radius, and swing
Crane placement decides what the job can lift, so it is one of the first logistics decisions, not one of the last. The crane has to reach the work, and reach is not a single number. A crane's capacity falls off as the radius grows, so the question is never just can it reach the spot, but can it lift that load at that radius. You read the rated capacity off the manufacturer's load chart for the specific configuration, at both the pick radius where the load is rigged and the set radius where it lands.
Three geometries govern the placement. The pick radius and set radius determine whether the load is within capacity. The swing path determines what the boom and the load sweep over, which has to be clear of the public, the crew, and adjacent property. The setup determines whether the ground can take it: outrigger pads or crane mats sized to the bearing capacity, because a crane that settles is a crane that tips. Tail swing on the counterweight catches people who only watched the load.
Lay the staging out to match the crane, not the other way around. Material that has to be flown lands inside the crane's swing so it can be picked without a second move. The detailed lift planning, the rigging, the wind limits, the ground-bearing verification, and the exclusion zones belong to the crane and rigging discipline and the lift plan, and they are a safety document in their own right. The logistics plan's job is to put the crane where it can reach the work and keep the swing clear of everything that should not be under a load.
Vertical transport on a high-rise
On a high-rise, getting material and people up the building becomes its own logistics problem, and it is usually the bottleneck. Once a building goes past a few stories, you cannot carry the work up the stairs, so a construction hoist, a rack-and-pinion lift mounted to the structure, moves the load. The hoist becomes the throat the whole job breathes through.
Plan the hoist capacity against the peak demand, not the average. During finishes, several trades all want the hoist at once to move material to their floors, and the crew that cannot get a cage is a crew standing still. Twin-cage hoists exist for exactly this reason, and the larger the building, the more the vertical-transport capacity drives the finish schedule. Where the building's permanent elevators can be put into temporary service under the right protections, that capacity helps, but it has to be planned and protected, not assumed.
Tie the vertical plan to the delivery plan. A just-in-time delivery to the 30th floor is only as fast as the hoist that carries it up, so the delivery window and the hoist schedule are the same conversation.
Temporary facilities and crew flow
Temporary facilities are the site's plumbing and bones: the field office and trailers, the gang boxes and tool storage, parking, the break area, the toilets, and the temporary power and water. On most jobs the general contractor sets these up and the trades plug into them, so the logistics plan locates them where they serve the work without eating the laydown or blocking the haul route.
Put the facilities where they do not move. A trailer is a pain to relocate, so site it clear of the building footprint and the phases that will claim ground later, or you will be dragging the office across the site mid-job. Toilets and the break area belong near where the crew actually works, because every minute of walk to a toilet at the far corner is a minute off the tools, multiplied by the whole crew, every day.
Crew flow is part of this. Where people park, the path they walk from the gate to the work, where they badge in on a secured site, and how that walking path crosses the truck routes all belong on the plan. The walk-to-work distance is a quiet schedule cost nobody budgets, and the crossing points between people on foot and trucks on the haul road are where the separation has to be designed, not left to luck.
Traffic control and pedestrian protection
The moment the work touches the public right-of-way, traffic and pedestrian protection stop being optional and become a permit and a legal duty. The plan that covers it goes by maintenance of traffic, or MOT, and the traffic control plan: how vehicles, pedestrians, and bikes move safely past the work. On public work it follows the Manual on Uniform Traffic Control Devices and the jurisdiction's own standards, and the specifics are set by the AHJ.
Pedestrians are the exposure that bites hardest, because a member of the public hurt on your site is a different order of problem than a crew injury. When the work blocks a sidewalk, you provide a protected alternate route, clearly marked, separated from the work, and accessible. Where there is overhead work above a walkway, the protection is a covered walkway or sidewalk shed built to take the falling object the work could drop. A flagger directs traffic where signs alone cannot, and on lane closures the setup follows the standard taper and signing, not a guess.
Do not treat the public as someone else's problem. Ignoring pedestrian protection is one of the fastest ways to get a stop-work order, and the bad press and the liability from a hurt pedestrian outlast the job. Plan the public's path with the same care as the crew's, because the jurisdiction and the contract both require it and the AHJ will check.
Site security: fencing, gates, and after-hours
Security starts with the fence. A perimeter fence with controlled gates defines who is on the site and keeps the public and the curious out, which is a safety duty as much as a theft one, because an unsecured site after hours is your liability when someone wanders in and gets hurt. Anti-climb fencing and vehicle barriers harden the perimeter where the risk is real.
Theft is a steady cost the trade underplays. Tools, copper, equipment, and material walk off sites, and most of it happens after hours and on weekends when nobody is watching. The defenses stack: lock the gate, light the site, lock equipment and pull the keys, store the high-value material where it is not visible from the street, and cover the blind spots with cameras or a remote-monitored video service. Keep the valuable material away from the fence line, where a thief can reach or cut to it.
Build the after-hours plan into the logistics plan, not as an afterthought. Where the gate locks, who has keys, where the cameras see, and how the site looks at midnight are part of the layout. A site that is buttoned up before the crew leaves is the site that does not lose a Monday morning to a break-in.
Waste, dumpsters, and keeping the routes clear
Waste has to leave the site as fast as it is made, and that takes a plan too. Locate the dumpsters where trades can reach them without crossing the whole site, and where the haul truck can pull in to swap them without blocking the gate. On a high-rise, a trash chute moves debris down the building so the crew is not hauling waste through the hoist that material needs.
Cleanup is a logistics function, not just housekeeping. Debris in the access routes and the egress paths is the same problem as material in the wrong place: it blocks the flow and it trips people. Keeping the routes clear is the daily discipline that keeps the rest of the plan working, and it ties directly into the site's housekeeping practice, which is where the separate guidance on a clean and ordered site lives.
Plan the waste stream by phase like everything else. Demolition makes different debris than finishes, the dumpster count changes with the trades on site, and the day the dumpsters are full and not swapped is the day the waste starts piling in the walkways.
Coordinating logistics across the trades
On a job with one gate, one crane, and one laydown, the logistics belong to everyone and the conflict is constant. Two trades both want the crane Tuesday morning. Three trades want the same patch of slab for staging. A delivery for one blocks the unloading zone another booked. None of that resolves itself, so the coordination is a meeting, run regularly, where the shared resources get scheduled the same way the work does.
Book the shared resources like you book the work. The crane gets a daily pick schedule, the laydown gets assigned zones by trade, the gate gets delivery windows. This is the same coordination muscle the look-ahead and the pull-planning sessions use for the schedule, and it works best when the logistics and the schedule are coordinated in the same room, because a crane pick is both an activity in time and a use of a shared machine in space.
Make one person the owner. Logistics with no owner is logistics by whoever shows up first, which is how the gate ends up blocked and the laydown ends up double-booked. On most jobs the general contractor's superintendent owns the site logistics and the trades coordinate through that person. The owner is who the delivery driver calls and who settles the Tuesday-morning crane fight before it becomes a stalled crew.
How do you handle logistics on a tight urban site?
A tight urban site is the hardest logistics problem in construction, because the thing every plan depends on, space, is the thing you do not have. There is no laydown, the building fills the lot to the property lines, the only frontage is a public street, and the neighbors and pedestrians are feet away. Everything that is easy on an open site is a permit and a negotiation here.
The urban playbook leans hard on a few moves. Deliveries go just-in-time because there is nowhere to store, and they are scheduled tight, sometimes into off-peak or night windows to avoid the daytime congestion, where the jurisdiction allows it and the noise rules permit. The street becomes the unloading zone under a curb-lane permit, often with a flagger. A sidewalk shed protects the pedestrians who keep using the sidewalk through the whole build. The crane swings over a property line only with the agreements and permits that allow an oversail, which the AHJ and the neighbors control.
The other half is the relationships. On a tight urban site you coordinate with the neighbors, the businesses, and the city, because they can stop you cold. Understand the traffic patterns and the congestion hours before you set the delivery windows, talk to the people next door before the noise starts, and treat the permit conditions as the hard constraints they are. The site is small, but the list of people who can shut it down is long.
Temporary utilities and locating before you dig
Temporary power and water are what let the site run before the building's permanent systems exist, and they are part of the logistics layout. Temporary power is an engineered, code-compliant system, not a few extension cords off the neighbor's panel, and the larger equipment, a tower crane or a high-rise hoist, often needs three-phase service that has to be planned and brought in early. Route the temporary power and water so they reach the work without crossing the haul roads where a truck will tear them out.
Before any of it goes in the ground, locate what is already down there. Call 811 before you dig, every dig, and let the public locating service mark the electric, gas, water, and communication lines, which most jurisdictions require by law a few business days ahead. The free service marks public utilities to the meter. Anything private past the meter, the lines feeding outbuildings, the abandoned services, the site's own temporary runs, needs a private locator, and the detail on calling before you dig lives in the utility-locating guidance.
Hitting an unmarked line is the kind of mistake that stops being about logistics and starts being about a gas leak or an outage. Locate first. It is cheap, it is required, and it is the one step where skipping it can put people in the hospital and the job in the news.
Logistics is safety: separating people and equipment
The logistics plan is a safety document whether or not anyone labels it one. The core hazard on a logistics-heavy site is the struck-by: a worker on foot hit by a truck, a swinging load, a piece of moving equipment. Most of those incidents trace back to a layout that put people and equipment in the same space at the same time, which is exactly what the logistics plan is supposed to prevent.
Separation is the design principle. Keep the walking paths off the haul roads, and where they must cross, control the crossing with signage, a flagger, or hard barriers. Keep the crane's swing path clear of active work and the public. Give backing trucks a spotter or design the circulation so they never back blind. The struck-by guidance covers the hazard in depth, and the logistics plan is where you build the protection into the geometry of the site instead of relying on people to dodge.
Design it out, do not train it away. A toolbox talk about watching for trucks is no substitute for a haul road that does not run through the break area. The plan that separates people from equipment by layout is the plan that does not depend on everyone paying attention on the worst day.
Plan the logistics in precon, before mobilization
The logistics plan belongs in preconstruction, on paper, before the crew mobilizes. The cheapest time to figure out that the crane cannot reach the back of the building or that the only gate cannot take a mixer is while it is still lines on a drawing, not the morning the pour is scheduled. A job that plans the logistics on the fly is a job that discovers its constraints by hitting them.
Precon is where the logistics get tied to the schedule and the budget. The crane you need, the hoist capacity, the street permits, the temporary power service, the phasing of the laydown: those have cost and lead time, and they get priced and sequenced during preconstruction alongside the rest of the plan. The preconstruction guide covers how the early planning locks the budget and the approach before construction starts, and the site logistics is one of the pieces that gets set there.
Walk the site before you draw the plan. The drawing tells you the lot lines and the building footprint. It does not tell you the low bridge on the only truck route, the neighbor's loading dock that shares your alley, or the slope that turns to mud. The plan made from a desk is the plan that meets reality at the gate.
Keeping the plan current and the records straight
A logistics plan that does not get updated is a plan that is wrong by month three. The site changes by phase, the crane moves, the laydown shrinks, a new foundation blocks a gate, and the plan has to change with it. Update it at every major phase transition and any time the configuration shifts, then communicate the change, because a plan that updates in one person's head is not an update at all.
Communicate it the way the field actually receives information. The current site plan, the active delivery schedule, and the permit conditions all have to reach the trades, the delivery drivers, and the new crew member on day one. A field tool like FieldOS keeps the current plan, the delivery calendar, and the logistics rules in one place the whole site can see, so the version on the drywall trade's phone is the version the superintendent actually drew.
Keep the records too. The logistics plan by phase, the delivery schedule and the receiving tickets, the crane and lift plans, and the street and MOT permits are the paper that proves the site was run the way the contract and the AHJ required. Capturing them as the job runs, in a tool like FieldOS rather than a pile of emails, is what lets you answer the question later instead of reconstructing it from memory.
What to document
The logistics record is what proves the site was planned, not improvised, and it is what a new trade, a driver, or an inspector reads to understand the site. Capture the layout for each phase and the rules that go with it.
| Element | What the plan shows | Note |
|---|---|---|
| Site plan by phase | Gates, routes, laydown, crane, facilities | One drawing per major phase |
| Access and haul routes | Gates, one-way circulation, unloading zones | Check turning radius for the largest vehicle |
| Laydown and staging | Zones assigned by trade, near the work | Mark no-go and protected-material areas |
| Crane and hoist | Position, swing path, pick and set radii | Lift plan is a separate safety document |
| Delivery schedule | Windows, unloading zone, who receives | Tie to the look-ahead schedule |
| Temporary facilities | Trailers, parking, toilets, power, water | Site clear of future building footprint |
| Traffic and pedestrian | MOT plan, sidewalk shed, flagger, detours | Per the jurisdiction and the AHJ |
| Permits | Street occupancy, MOT, crane oversail | Carry the conditions on the plan |
Common mistakes
- Running the job with no site logistics plan, so the layout lives in one person's head and dies when they are out.
- No laydown or staging assigned, so material lands wherever the truck stops and gets double-handled.
- Blocked access or haul routes, so a parked or backing truck shuts the only gate.
- A crane sited where it cannot lift the load at the radius the work requires.
- No delivery coordination, so trucks stack up at the gate and the crew waits on material with nowhere to unload.
- Ignoring public and pedestrian protection, which draws a stop-work order and owns you the liability when someone is hurt.
- Planning the logistics once and never updating it as the site shrinks and the phase changes.

Standards and references
Site logistics is governed less by a single code and more by the contract, the site, and the AHJ, so the references are a mix of practice, safety regulation, and local permits. Site utilization and site logistics planning is established construction-management practice rather than a numbered standard, and the owner or general contractor usually sets the format and the requirement in the contract documents. What the plan must contain, and whether the jurisdiction requires a construction logistics plan at all, is set by the contract and the AHJ.
On the safety side, the OSHA construction standards in 29 CFR 1926 cover the hazards the logistics plan designs around, including the struck-by exposures, the crane and rigging requirements, and site access and egress. Crane work follows the crane and rigging requirements and a lift plan developed for the specific pick. Traffic and pedestrian control on public ways follows the Manual on Uniform Traffic Control Devices and the jurisdiction's own work-zone standards, and the street, lane, and pedestrian-protection permits come from the local authority. Calling before you dig is required by state law, commonly through the 811 one-call system.
The thread through all of it: plan the logistics by phase in precon, site the laydown and the crane so material lands near the work and the crane can reach it, and coordinate the deliveries while protecting the public. The contract documents, the jurisdiction, and the AHJ control the specifics, and the adopted requirements and local conditions govern over any rule of thumb in this guide.

FAQ
What is a site logistics plan?
A site logistics plan is the layout and rules for moving people, material, and equipment on and around a jobsite. It maps laydown and staging, access and haul routes, crane and hoist placement, temporary facilities, deliveries, and pedestrian protection, and it is updated by phase as the site changes. The contract and the AHJ set what it must contain.
What is a laydown area in construction?
A laydown area is where material is received and stored on site before it is installed. Staging is the related spot where material sits ready, near the work. Good laydown keeps material close to the point of install, off the access routes, and protected. On a tight site there is little or none, which pushes the job toward just-in-time delivery.
What is just-in-time delivery in construction?
Just-in-time delivery means material arrives close to when it is installed rather than being stockpiled. It is the standard move on tight sites with no room to store, but it removes the buffer a stockpile gives you, so a late truck stops the crew. It only works with tight delivery coordination, a reliable supplier, and someone owning the calendar.
Why does site logistics matter if the schedule is already good?
A great schedule fails without a place to put things. The schedule says when the work happens; the logistics plan says where material lands, how trucks get in, and whether the crane can reach. A scheduled job still stalls if the truck has nowhere to unload. On a tight site, logistics matters as much as the schedule.
How does the site logistics plan change as the job goes on?
Logistics change by phase because the site shrinks as the building grows. The laydown you used during excavation is under the building by finishes. Excavation needs clear haul routes, structure orbits the crane's reach, and finishes run on just-in-time delivery and vertical transport. Plan one logistics layout per major phase and update it at every transition.
Where should a crane be placed on a jobsite?
Place the crane where it can lift the required load at the radius the work demands, verified against the load chart, because capacity falls off as the radius grows. Keep the swing path clear of the public, the crew, and adjacent property, and confirm the ground bearing for the setup. Lay staging inside the swing so loads are picked once.
Do I need a permit for construction deliveries on a city street?
Usually yes. Unloading from a public street typically needs a street-occupancy or curb-lane permit from the jurisdiction, often with a flagger and a defined time window. Blocking a sidewalk adds pedestrian-protection requirements like a covered walkway. The exact permits, conditions, and hours are set by the local authority and the AHJ, so confirm before you schedule the delivery.
How do you handle logistics on a tight urban site with no laydown?
Run just-in-time delivery on tight scheduled windows, sometimes off-peak or at night where allowed, because there is nowhere to store. Use the street as the unloading zone under a curb-lane permit, protect pedestrians with a sidewalk shed, and coordinate with the neighbors and the city. The crane swings over a property line only with the oversail agreements the AHJ controls.
Who owns the site logistics on a multi-trade job?
On most jobs the general contractor's superintendent owns the site logistics, and the trades coordinate the shared crane, laydown, and gate through that person in a regular meeting. Logistics with no owner becomes logistics by whoever shows up first, which is how the gate ends up blocked and the laydown double-booked. One owner settles conflicts before they stall the crew.
How is site logistics related to jobsite safety?
The logistics plan is a safety document, because the main hazard on a busy site is the struck-by: a worker hit by a truck, a load, or moving equipment. Separating walking paths from haul roads and crane swing by layout designs the hazard out, instead of relying on people to dodge. Build the separation into the site geometry.
