Construction Project Observations

.. ld move the beams away from the steel beam piles to other workers who would bolt the beams into position. You could observe today that workers have begun to lay steel sheets on the second story that has already been assembled. This steel is placed over the floor trusses and then bolted down. Within in the site there was a concrete bucket for the crane, which will most likely be used to pour concrete for the individual floors.

They can only lay the steel and pour one floor at a time or the steel from the above floor will be in the way of getting the concrete bucket through. Within the construction site were piles of wire mesh and reinforcement bars. This probably will be used as reinforcement for the concrete floors. Safety remained important through out this phase of construction and was demonstrated through rails, which were placed around the floors and during the systematic processes used during the hooking and moving of individual steam beams. There were four electricity trucks present today and they appeared to be digging the power supply line to the building. Three men and a digging machine conducted the digging of the power supply line.

February 3, 2000 On the afternoon of Thursday February 3, the site, just by looking, didn’t seem to have made any progress from the previous day. However, workers were going down into the basement. Due to safety concerns, visitors were not allowed down below the structure. In order to find out what was happening, discussions with engineer Charles Pickar of Sebesta Blomberg and Associates, Inc. were used to fill in the blanks. He explained that the electricians and pipe fitters were working in the basement running conduit and laying pipe.

As soon as they were done, the fire suppression people could get down there to spray the piping. They were working to get the necessary wiring complete so more equipment could be lowered and hooked up as soon as weather allowed. As for now, the site was supplied power through a shed, which was tapped into a near by permanent power supply. Some parts of the basement were already filled in, but one main hole was left opened to get the transformers and air handling units down. Also in the basement, men were laying diamond supports on the steel footings to prevent cracking in the concrete foundation from the stress of the columns. These processes all continued underground through the afternoon. February 4, 2000 The snow and wind on the afternoon of Friday, February 4 again forced the ironworkers to abandon lying any additional floor decking.

A crew of three men prepared to drop a transformer into the basement. The crane was extendible and looked to be at about 100 ft. The riggers took their time securing the connection, but due to wind, never attempted to move the unit. Mr. Pickar later explained that this particular type of crane is not very stable. If the load sways while being transferred, there is a great possibility that it will flip. Keeping in mind operator safety, as well as the safety of nearby crewmembers, risks are just too great to attempt transfer today.

Tarps covered the transistors and the crane lowered and folded up. Mr. Pickar also mentioned that a late delivery of hangers for the basement earlier in the project was already pushing everything behind schedule. The weather problems further added to those delays. Looking at the architectural drawings covering several tables in the construction office, it was noted that there will eventually be a tunnel running underground out the north end of the library and into nearby buildings. Several revisions had to be made on these drawings, especially in regards to the structure itself, to modify the ideas of the designer with the feasibility of engineering. Sebesta Blomberg, which is primarily an engineering company, did most of the modifications.

There were almost 1000 pages just of architectural design and several other books of drawings, such as electrical and mechanical work, which were equally as thick. These all seemed to be labeled in an efficient manner to assure that pages could be easily located. This is especially useful when phone calls come in and someone needs to know something like a dimension on a certain machine in a certain room. People with identical books can easily direct another over the phone to a specific page. Depending on the type of work it entails, specific areas within each book are easy to find just by reading the markings on the bottom corners of the pages. Safety Issues In reference to safety issues other than the specific situations mentioned before, it was noted that anyone entering the site was required to wear a hard hat as well as construction boots. Every worker wore thick gloves and some wore safety eyeglasses.

All crane operations were taken slowly and all ironwork was called off at the first signs of slickness or dangerous winds. Anyone operating machinery, such as the welders or crane operators were trained and certified prior to working. All visitors were required to sign in and out to alert those in charge as to who was on site in case of an emergency. The construction office bookcase was filled with safety manuals, OSHA guides, project management workbooks, structural welding guides etc. All the drawings contained clear markings referring to placement of safety equipment, such as fire alarm and hose reels.

Safety inspection was accounted for in the scheduling process and any sort of risks taken very seriously by all members of the working and management crew. Construction Observation Conclusions In conclusion, this construction project reflects a complex system of seemingly unrelated activities, which in actuality are crucially dependent on one another. The timing of the start and finish of every little detail is scheduled so that it fits in the order necessary to complete the project in the most efficient way. Advanced planning, foresight, and experience are used to ensure processes are done in the right order. An example of this is the basement project. The design must call for a section of flooring to be left out. Hangers have to go in before wire and pipes, which have to go in before machinery, which has to go in before fire safety equipment and inspection, which has to be done before the floor gets closed up. Each link in the chain is essential.

Delays can easily build up fast if one link can’t finish the job. It’s the responsibility of the construction manager to ensure that materials get there on time and that workers have the qualifications and tools necessary to complete the task. The construction manager must keep an eye on all aspects of the project, paying special attention to safety codes and restrictions, and understand the interdependence of each days events in order to avoid delays, maintain a safe working environment, and keep the schedule moving smoothly until every final detail has reached completion.
