This project is for several new sidewalks
to be placed around the West and South sides of Samford Hall (See Plan
in folder). Facilities Division will pour the bulk of the job but
our team will be responsible for one section for each member. One
section will be 8’ x 8’ x 8”, or about 73728 in3 (1.58 yd3). The
sidewalk is bordered by brick rows on both sides and between each 8-ft.
section. See Section below.

Pre-construction Measures and Photos:
Since this was a project that was
in conjunction with Facilities, some of the site preparation was already
completed prior to our arrival. Pre-excavation photographs were unavailable.
Design | Member Sizing | Reinforcement Placement:
See blueline in binder pocket. The
design, sizing, and reinforcement was based on original sidewalk design
around and adjacent to Samford Hall.
Weekly Progress Report:
This project was completed in one
week, therefore no weekly updates were necessary. The schedule below
reflects the actual schedule.

Quantity Takeoff and Cost Estimate:
Although all equipment, tools, and
concrete will be supplied by Facilities, we have included, as a rough estimate,
what the job would cost had we been responsible for coordinating those
items.
Concrete: 8 sections (1.5 yd3
per section)@ $60.00 per yd3 = $1200.00 (includes
10% overage figured in the brick troughs)
Tools: (trowels, spreaders, floats,
shovels, hammers, powersaws, broom, string, etc.) = estimated rent for
this equipment for 5 days @ $25.00 per day = $125.00
Heavy Equipment: Backhoe for 1
day site prep = $150.00 (est.)
Truck for 5 days = $250.00
Formwork lumber: 370 board feet
@~$0.15 per ft = $60.00 (includes 10% overage)
Head protection: Hardhats are highly recommended, although
not routinely worn by Facilities personnel.
Foot protection: Steel toed safety shoes or boots are
recommended. Waterproof rubber boots are also recommended.
Hand and Arm protection: Long sleeves and gloves are
recommended.
Eye protection: Goggles or glasses.
Water/Fluids: A cooler of Gatorade will be kept on site.
Injuries: small injuries will be treated on site with
a basic first aid kit or at taken to Drake Clinic,
life threatning injuries will be evacuated via EMS to East Alabama
Medical Ctr.
Telephone: available at Samford Hall and/or Mary Martin
Hall
Innovations | Time Saving Measures:
The construction personnel we were working with already established
many of the innovations and procedures. There were many "tricks of
the trade" that were learned: too many to list here.
Principle duties carried out by group members:
Our original plan was to have group members be responsible for
supervising the preparation and pouring of their own sections. Also,
group members would have rotated between the jobs of spreader, strikeoff
persons, trowler, floater, etc. However, Facilities poured the entire
eight sections at once, causing each group member to rotate between functions
as the job progressed.
Our group was interested in the structural aspects of Fibermesh,
since it was used in the sidewalk project. Fibermesh strands actually
block the formation of "macro-cracks" by blocking the formation of "micro-cracks."
"The addition of Fibermesh fibers throughout the concrete also serves to
minimize the width and length of those cracks that may appear in the hardened
state."
A surprising feature of Fibermesh was that no mixture adjustments
are necessary and that it works with any admixture: this is due to the
fact that Fibermesh's actions are all mechanical.
Conclusion | Lessons learned:
This project was very informative in exposing each group member
to the actual "hands-on" aspects of working with concrete. Unlike
other structure classes, which teach only "paper problems," this project
focuses on the "real."
In addition, we learned how fast concrete sets. We poured
eight sections at once beginning at 8:00AM and was brooming by 11:00AM.
