Natural Slate roof matching Main Building’s
Exposed heavy timber trusses

10. Project Background Site Improvement Features Demolition
Trees and shrubs
Tennis courts
Sidewalks and asphalt roads
Athletic fields
Playground area
Fencing and signage
Sewer piping & structures

11. Project Background Site Improvement Features New Construction
Sanitary and storm sewer piping - structures
Underground electrical & telecommunications
New parking lots, campus roads, sidewalks, curbs
Seven new tennis courts
Two new athletic fields with new sod turf
Site fencing
Playground area with safety surface
Landscaping and site furnishings

12. Site Renovation Planning
Pre – Construction Planning
Purpose
Alleviate headaches during construction
Possible cost and time savings
Avoid delays by staying on top of issues
Permits
Long lead time items
Create communication between all project members
Owner
Designers
Construction Manager & Subcontractors

13. Site Renovation Planning
Pre – Construction Planning
Key items to be addressed
Review schedule dates – make sure all are in agreement
Parking requirements – temporary parking lot
Permits
Site utilities, sewer tie-ins
Road closure
Meet with neighbors and address concerns
Home inspections
Site specific safety plan

14. Site Renovation Planning
Pre – Construction Planning
Key items to be addressed
Locate existing utilities
Submittals for long lead time items
Underground piping and structures
Contract a testing consultant
Concrete pours
Soil compaction rates
Discuss site access with Owner

15. Site Renovation Planning
Site Access
Not 100% accessible throughout summer
May 29, 2001 – small section available
June 11, 2001 – remainder of site available
Day camps from June 18th – August 3rd
DEMO
ALLOWED

16. Site Renovation Planning
Addressing the issues
Communication between all parties
Schedule
Constructability
Address all issues early
Develop site layout plan
Use new technology to assist with planning
Project collaboration via the internet
4D CAD

17. 4D CAD
What is 4D CAD?

18. 4D CAD Advantages & Disadvantages Advantages
Ability to clearly communicate plan
Identify major issues ahead of time
Owner’s needs
Constructability
Develop a sequencing plan
Balance resources – crews and equipment

19. 4D CAD Advantages & Disadvantages Disadvantages
Time intensive to develop
Expensive
In House
Outsourced
Desired level of detail can be difficult to achieve

20. 4D CAD Benefits for WPCS Site Improvements Construction Manager (GC)
Gives opportunity to correct conflicts before they arise in the field during a tight schedule
Owner
Site access plan – what the contractor expects
Subcontractors
Allows subs to see number of crews necessary to complete work
Where they should be at all times

21. 4D CAD

22. 4D CAD

23. 4D CAD Recommendation Not recommended for WPCS Site Improvements
Smaller project
Effectively communicate the plan during Pre-Construction
Utilize One or Two Week Look-Aheads

24. Floor System Redesign VS.
Concrete Masonry Units – Open Web Steel Joists –
Slab on Metal Deck
VS.
Concrete Masonry Units – Precast Hollow Core Planks

25. Hollow Core Precast Planks
Original System
Welded bearing plate
4” Slab on Metal Deck
8” Bond Beam
K Series joists ranging from 10 – 26” deep
8” CMU

26. Hollow Core Precast Planks
Proposed System
Reinforcement
2” topping slab
8” Precast hollow core plank
8” Bond Beam
8” CMU

27. Hollow Core Precast Planks
System Comparison
Steel Joists
Hollow Core Plank
10”-26” depth
10” (8” + 2”) deep
3’ O.C.
4’ O.C.
Vibration Considerations
No vibration
Acoustical Issues
Sound Attenuation
Bridging needed to stabilize
Laterally Stable
Tack Welded to deck
No Metal Deck
9 different types of joists
1 type of concrete plank
Welded to steel plate at bearing
Reinforcing at Connection to Wall

28. Hollow Core Precast Planks
Schedule Comparison – Saves 22 days
1st & 2nd Floor Sequence
Roof enclosed by October 18th

29. Hollow Core Precast Planks
Cost Comparison
Original Floor System
$202,764
Precast Plank System
$180,581
Cost Savings
$22,183

30. Hollow Core Precast Planks
Conclusion
Recommendation Precast Planks
Simpler for field construction
Produces minor cost savings
Shortens schedule for earlier enclosure
