Executive Summary
The following report contains information pertaining to the existing conditions at Kiski Area
High School. Although the campus looks very spacious, the available room for temporary site
equipment and utilities is very limited due the close proximity of the schools. The school had given
the general contractor permission to use part of the back parking lot for the trailers and staging
area. I feel that this was the best location for the trailers because of the available utilities that
run through the area and the convenient location to the project site.
A unique aspect to this project is the project delivery system. The owners of the project
did not want to proceed with a Traditional Design-Bid-Build system with a Multiple Prime Contract.
The reasons for this being the size and complexity of the project as discussed in the next couple of
pages. Therefore, the owners received permission for a Traditional Design-Bid-Build system with a
Single Prime Contract. The two main factors that complicate this project are the two new buildings
being constructed between eight existing structures and the connecting multiple buildings. This
requires a lot of planning on the general contractors’ part.

Project Delivery System
The delivery system for this project is a Traditional Design-Bid-Build method with a Single
Prime Contract (see attached). However, Pennsylvania code requires that the project delivery
system for a school be Traditional Design-Bid-Build method with a Multiple Prime Contract. The
owners of the projects at Kiski Area High School, the Board of Directors, petitioned this code.
Based on the size and complexity of the contract, the School Board received permission to use a
Single Prime Contract.
The School Board hired Ackenheil Engineers early in the project to perform site test
borings, in which the architects, Canzian/Johnston and Associates, worked with the geotechnical
engineers to determine the foundations for the buildings. The owner chose the architects,
Canzian/Johnston and Associates, because of their experience with designs of educational facilities
in the neighboring school districts. The architect fee was a percentage of the actual construction
cost; they then contracted out percentage fees to their specialty consultants.
The project went out for bid in February 2003. P.J. Dick won the bid and proposed a lump
sum contract for the work. They then held lump sum contracts with the subcontractors.

Project Schedule Summary There are a total of eight different phases for this project. The overall completion date
for Kiski Area High School is set for October 31, 2005. The construction onsite began in April
2003, allowing for 31 months to complete the project. The general contractors, P. J. Dick, have
developed an accelerated schedule and anticipate the completion date to be April 2005.
The design phase for this project began in February 2001 and the bid documents were
finished by March 2003. Some of the unique aspects of these buildings that can create problems
for the schedule are: tying the new structure into several different buildings and the load bearing
walls. The classroom building, Building N, ties into four existing buildings and the new gymnasium
building. Similarly, the new gymnasium also ties into three existing buildings. Another unique
aspect are the load bearing walls for this project. This can create a lot of problems not only for
the schedule but also onsite due to all of the tradesmen needed to work in one area. For example,
the electricians need to work with the block layers because of the conduit that runs through the
block wall. Also, the load bearing block walls have an effect on the steel erectors as well. If they
are not built in time for the steel erector to erect the steel beams this can have serious effects on
the overall progress of the project.

• Design Costs Design Costs (6%) - $1,868,220
• D4 Cost Estimating (see attached ) - $32,318,963 • Square Foot Estimate (see attached ) - $9,967,582
The D4 Cost Estimating and Actual Construction Costs were approximately the same. In D4
Cost Estimating, the estimate was an average of six (6) similar projects. The basis for comparison
of the projects was the square footage of the site, number of floors, and the building type. Of
4

Sarah Haynes Construction Management Primary Faculty Consultant: Messner Due: October 8, 2003
these three characteristics, one of the six projects was also a renovation and addition to a high
school. Meanwhile, the remaining five projects were of new construction.
The square foot estimate was calculated by using R. S. Means (2003 Ed). The square foot
estimate was in no way comparable to the actual cost of construction. The main reason for this is
that the project at Kiski Area High School includes renovation and asbestos removal in the eight
existing buildings and demolition of one existing building, while the square foot estimate only
includes the construction of two new buildings on campus. R. S. Means cannot calculate the cost of
demolition and renovation. Another reason why for the large difference in values is the complexity
of the job. Onsite at Kiski Area High School, the new classroom building is tied into four existing
buildings and the new gymnasium building. Also, the new gymnasium building is tied into three
additional existing buildings on campus.

Site Plan
There are two main roadways to the site from Hyde Park Road located north and west of
the construction site. The deliveries made to the site will enter through the northwest entrance
and continue to the south side of the school. There the superintendent will direct the trucks to
the staging areas located either behind the buildings or in front of the trailers. The delivery truck
will then exit through the north entrance of the site. There are no restrictions to the time of
delivered materials onsite.
The drawing PH1.1 (see attached) is the overall site plan of Kiski Area High School. P. J.
Dick has received permission from Kiski Area High School to use some of the existing utilities
onsite such as the internet, plumbing line, and water line. Due to the size of the project and the
various locations of work the dumpsters onsite will be moved throughout the duration of the
project. In the start of the project there was one crane onsite for the demolition of Building D,
this can be seen in both the overall site plan and the area plan on drawing PH1.2. The room for
parking onsite is rather difficult due to the number of students and faculty at Kiski High School.
Therefore, the best location for parking is below the football field.

Local Market Conditions
The project site at Kiski Area High School is approximately 50 minutes away (35 miles)
from Pittsburgh, Pennsylvania. There are very few projects in and around the city that are in
progress therefore, the current labor market is ample. Some projects in the area include the
Collaborative Innovation Center at Carnegie Mellon University for $27.8 million and the Springfield
Elementary School for $10.1 million.
P.J. Dick Inc. is the general contractor on the Kiski Area High School project. They are a
non-union contractor working on a job with union subcontractors. The required pay on the job is
prevailing wage. There was no clause in the contract requiring the employment of disadvantaged
businesses.

Subsurface/Soils
The owners of Kiski Area High School had hired Ackenheil Engineers to perform site test
borings for the proposed projects. On September 2nd, 2001, five (5) of the ten (10) test borings
were drilled to an average depth of 23.78ft for that day. On September 3rd, 2001, the remaining
five (5) test borings were drilled to an average depth of 19.16ft for that day. According to the
geotechnical report that was prepared on September 12, 2001, the existing fill consisted of a
mixture of soft to very stiff or medium dense silt, clay, and sand in addition to small fractions of
rock, coal and gravel. Ackenheil Engineers did not recommend that the new Classroom and
Gymnasium Additions be supported by the existing fill due to the compressible soils. The report
also stated that beneath the existing fill, alluvial soils were found consisting primarily of stiff silt
and clay atop of medium dense to dense sand. With this information, the engineers stated that the
alluvial soil that was encountered during drilling was suitable to support the Classroom Addition on
spread footing foundations. Beneath the alluvial soils, dense to very dense residual soil made up of
sandstone and shale bedrock were encountered and a recommendation was made by Ackenheil
Engineers to use deep caisson foundations for the Gymnasium Addition.
During drilling, Ackenheil Engineers discovered that five of the ten test borings were dry
while the remaining five had encountered groundwater at various depths. The geotechnical
8

Sarah Haynes Construction Management Primary Faculty Consultant: Messner Due: October 8, 2003
engineers believe that the groundwater that was encountered in the five test borings was due to
the water added to the borehole during coring operations. The contract documents used on this job
were AIA Documents of 1997, there were no changes made to the original contract involving
differing site conditions. A copy of the soils report was provided to all of the contractors prior to
bidding.
Also included in the report from the geotechnical/civil engineer was a segment on mining
conditions. According to the report, the Western Pennsylvania Mine maps indicate an Upper
Freeport Coal Seam below the site that had possibly taken place in the early 1900’s. The top of the
coal seam was estimated by the engineers to be at a depth of 175ft below the ground floor
elevation of the Gymnasium Addition. Based on their knowledge of the types of soil and mining
operations, the engineers estimated a low risk of mine settlement damage to the structures.
There were two types of soil retention that was used at Kiski Area High School. One type
used onsite was sloping the sides of the excavation back on a 34 degree angle or 1 ½: 1 ratio when an
excavation reaches a height of 5ft. The second type of soil retention used onsite was engineered
trench boxes. The trench boxes had to extend at least 18 " above the top edge of the excavation.
These were used when there was not enough room to slope back or if time was of the issue.

Client Information The owners of the projects at Kiski Area High School are the Board of Directors.
Currently, there are nine (9) individuals administering the board. The Board of Directors is
responsible for communicating with the Architect and General Contractor the demands of the
faculty and community. The main contact for Kiski Area High School is the owners’ representative,
Paul Azinger, Maintenance Supervisor of the Kiski Area School District. The high school was
originally built in 1962 and has been renovated twice; two new additions were added to the school in
the years 1972 and 1998. The existing school as it stands today consists of eight (8) school
buildings and one (1) administration building. There are a total of 1,445 students enrolled in grades
9th through 12th at Kiski Area High School.
Some reasons why the Board of Directors decided to expand the Kiski Area High School
campus are the need to make the campus more secure and the need for more facilities. The
buildings at the existing campus are spread out over a large area, permitting students, faculty, and
visitors to enter/exit the buildings at any time during school hours. The new structures will
connect to the existing buildings and provide a new entrance/egress to the high school. The reason
being to monitor the number of visitors and students that enter/exit the school. Since the
10

Picture: Existing site courtesy of Kiski High School Webpage.
Sarah Haynes Construction Management Primary Faculty Consultant: Messner Due: October 8, 2003
classroom buildings have not been renovated since the original construction of the campus back in
1962, there was a vital need for newer facilities. The two new additions to the high school will
include twelve (12) science classrooms, (3) consumer science classrooms, a library, and a greenhouse.
The schedule is a very important aspect to the owners of Kiski Area High School. There is a
total of eight phases of construction for this project. Since there are many students on campus
and very little classrooms available, it is imperative that all of the buildings are turned over on their
due dates. The asbestos abatement of the eight (8) existing buildings was scheduled to take place
over the nine weeks of summer when school is out of session. This summer the subcontractor
managed to complete four (4) buildings that underwent this operation. Another concern of the
owners that has a direct impact on the schedule is the schools’ scheduled events throughout the
year. If P. J. Dick has a conflict with the school’s scheduled activities, they are responsible for
notifying the school of the conflicts and are to come to some sort of an agreement. This summer
several activities took place around the campus such as football camp, band camp, and soccer camps.
The quality of the project is another important aspect to the owners of Kiski Area High
School. Kiski Area High School is a very outstanding school, in which they pride themselves on the
educational success of their students and the academic programs that are offered at the school.
This pride is shown through the design and renovation of the new buildings. The School Board would

Sarah Haynes Construction Management Primary Faculty Consultant: Messner Due: October 8, 2003
like to have the project completed at the bid amount, however, they have been very helpful in
working with the architect and general contractor on changes with design.
The keys to completing the project to the owner’s satisfaction are: safety of the students
and faculty, on-time building turnover, few conflicts with school activities, low cost, and minimal
damage to the existing conditions. Onsite P. J. Dick has a full time safety personnel to monitor
potential risks onsite for both the construction workers and students wellbeing. Throughout
construction, the students and faculty are welcome to use the access roadway (south of the
campus) in order to use the football field, track or tennis courts. There are several pieces of heavy
equipment that travel along that road daily, therefore speed limit signs were posted and a
pedestrian walkway was created to ensure the students safety. Another important aspect to the
owner’s satisfaction is having minimal damages to the existing structures. Although renovation and
asbestos removal is taking place inside the buildings, the school must still be usable and presentable
even before the finishes are made to the project. Once a year, the school holds an open house
where parents are allowed to visit the school, it is important that the parents feel it is a safe
environment for their students.
