The placement of temporary power poles on the jobsite should be analyzed and planned so as not to be in the way of future concrete walkways and driveways, trenching for underground utilities, and large landscaping trees.
The builder should attempt to avoid the common occurrence toward the completion of the project of having to move one or more temporary power poles…not only costing money…but disrupting electrical power to a portion of the project while it is moved to another location.
For high-density condominium and apartment projects…and for large multi-unit tract housing…the initial placement of temporary power poles so as not to interfere with any future construction activities…can be difficult because of the scarcity of open, unused space within the completed project. These projects often have most of the available space filled-up with walkways, driveways, courtyard patios, common area parking, recreation and swimming pool areas, and landscaping.
For tight projects with limited space such as these…it is sometimes best to have the civil engineering surveyors stake the locations for temporary power poles as a separate distinct activity…or along with and in addition to some other early staking activities that brings the surveyors out to the jobsite.
The builder must spend some time at the start of the construction determining the desired locations for temporary power poles…so their exact locations can be plotted and laid-out in the field.
For detached tract housing the exercise of choosing locations for power poles is made easier by the leftover open space on each lot…but the builder still needs to ensure that the temporary power poles are out of the way of concrete driveways and walkways…as well as the underground utilities.
Some housing construction projects are required to install temporary chain-link fencing around the perimeter property-line of the building site for the duration of the project.
Nylon wind-screen covering the fence might also be required or added by the builder to enhance the appearance of the fence and the project.
On one particular large condominium project I worked on as superintendent…adjacent to a golf course…700 lineal feet of wind-screened chain-link fence installed only by driving the vertical steel posts into the ground…blew over twice during the windy season.
At a considerable expense to repair each time, the builder finally removed the wind-screen portion of the fencing. The money that was spent putting the fence back up twice could have paid for originally setting the posts in concrete…thus allowing the more attractive green-colored wind-screen to remain.
Suggestions to prevent the fence from being blown over by the wind are:
- Set each post in concrete
- Set every other post in concrete
- Give the fence a 45-degree jog in the shape of a “V” every 100 feet or so
- Use diagonal braces to support the offset posts at the point of the “V”
For large multi-unit projects having a construction duration of several years…when a chain-link fence is used for the jobsite enclosure with a swinging double gate for access into the project…the builder should consider something more substantial for the gate posts…in place of the standard round hollow tube poles driven into the ground.
Figure 5.1 shows a typical double gate for a chain-link fence. If hollow tube poles are used as posts…after a few weeks or months of opening and closing the clamps holding the gates to the vertical fence posts often come loose…dropping to the point where the gates drag along the ground.
The fence posts can also lean inward toward the center of the entrance…succumbing to the downward weight of the gates…resulting in the ends of the gates resting upon the ground…rather than being suspended 4 to 6 inches above ground as intended.
The jobsite superintendent each morning must then lift and drag these gates over the ground to open up the jobsite…and then do the same thing at the end of the day.
On one particular project that had a 30-foot wide entrance opening with two 15-foot wide gates…the fence posts at each gate were so flimsy that the superintendent had to actually lift each gate to them to swing open or closed.
For a project with a duration of several months or years long, the builder should plan ahead and design posts for chain-link fence gates that can survive the length of the construction. At the very least, the fence post uprights at the entrance gates should be set in concrete rather than merely driven into the ground.
On one project, we used steel I-beams set in concrete as the fence post uprights for a 30-foot wide opening…with two 15-foot chain-link gates. We had steel hooks welded to the I-beams at the correct height so the clamps on the gates rested directly below the horizontal rails of the gates. This approach prevented the clamps or the gate from slipping downward. Both gates swung freely open and closed a uniform 6 inches above the ground for the entire duration of the three-year project.
Subcontractors should notify the jobsite superintendent in advance when a storage container bin…full of materials…is being delivered to the jobsite…and instruct the bin delivery person what to do with the keys.
An occasional occurrence on a construction site is for a particular worker to ask the jobsite superintendent…on the first starting day for that particular building trade…if the superintendent has keys to their bin.
Whenever a subcontractor’s storage bin is delivered to the jobsite, the superintendent should ask the delivery person if the bin contains materials and is therefore locked…or empty and therefore unlocked…and what if anything are the instructions regarding keys to locked bins.
The problem to avoid here is placing the jobsite superintendent in the position of being clueless as to the situation regarding storage bins, locks, and keys…which the superintendent should not be involved in but nevertheless becomes involved in by virtue of often being the only person present to receive the delivery of the subcontractor’s storage container bin and to direct its placement on site.
The fiasco of not being able to start the work smoothly…because the subcontractor failed to communicate and coordinate clearly who had the keys to the storage bin…can be avoided by the simple policy of requiring subcontractors to notify the superintendent when storage bins are being delivered…and what if anything to do about the keys to fully stocked, locked bins.
Many subcontractors use storage bins placed on the jobsite to store materials…on large multi-unit tract housing, condominium, and apartment projects.
Typical trades who must store materials on the jobsite include framing, plumbing, electric, drywall, lathing, and painting.
During the planning stage before construction, the builder should select one location on the jobsite where storage bins can be placed without needing to be moved later.
Few things are more frustrating and disruptive for a subcontractor than to be asked to move a storage bin two or three times during the course of the construction. Picking up and moving a large storage bin is not a delicate operation…and materials and supplies which were once organized inside the bin are usually tossed all over the bin floor.
The builder cannot insist that subcontractors be organized and efficient in their materials management…and then disrupt and displace those same materials by repeatedly moving storage bins because of poor jobsite planning.
I have worked on two projects in which the builders used detached houses that came with the purchase of the land…as the construction jobsite office in lieu of a temporary trailer.
This approach saved the builder the expense of providing a temporary office trailer…but in both cases…these fixed-in-place houses became farther and farther away from the construction in-progress…as each new phase of tract houses moved farther away from the first phase closest to the house office.
These growing distances resulted in a forced and unnatural isolation between the field office and the construction…especially when the distance became too great to cover on foot.
A temporary office trailer allows the trailer to be moved so that the construction office is not more than a few hundred feet from the actual construction in-progress.
When planning for and designing the construction trailer location and orientation, several features should be considered to help keep the inside of the trailer clean.
First, the builder should consider placing loose clean gravel or temporary asphalt paving around the entrance to the trailer…to remove dirt and mud from shoes as people approach.
Second, a doormat can be placed at the entrance of the trailer…allowing people to wipe off their shoes before entering…and reminding them to do so.
Third, the builder should consider providing a roof or awning over the construction trailer door and stairs or ramp…so when it is raining…people can pause to wipe off their shoes underneath overhead protection.
