SF Cost Comparisons Can be Misleading

• Comparisons should be based on
• Same building types
• Similar locations and size
• Consistent type of work, new or remodeling
• Comparison of components should be consistent
• Average of all Structures SF cost 215
• Total Structures cost/total Structures SF 233
• Total project cost/ total Structures SF 310
• Total project cost/ building SF 437

16
Funding History

• Fluctuating funding has caused large variations
  in the number of projects advertised annually

17
Shelf History

• Due to funding shortfalls many building projects
  have gone to the shelf.

18
Cost History

• The Departments Building Facility Costs have
  increased 30 to 50 in the last year
• Factors that have contributed to this increase
• Material and labor cost increases
• Material cost stability
• Lack of bidding competition

19
Material Cost Increases

• Engineering News Record Indices for Lumber,
  Cement, Concrete, Structural Steel, Bar
  Reinforcing Steel, etc.

• RS Means Construction Cost Data Book

20
Recent Bidding Competition

• Average number of bidders per projects 2.5
• 21 projects, July 2005 - December 2005
• Average number of bidders per projects 4.1
• 7 projects, January 2006 March 2006

23
What Are We Doing Now?

• Using forecasting tools in addition to historical
  bid results
• Estimates at DES building milestones
• Estimate more frequently after FPSE, up to CTC
  Vote
• Encouraging District Bidder outreach
• Advertise in building trade publications
• McGraw-Hill, Reed, Dodge, etc.
• Contact local contractors and associations

24
DES Building Estimating Milestones

• Draft Project Study Report
• Project Study Report
• 25, Preliminary design complete
• 50 or 80
• Draft PSE
• Final PSE
• Before CTC vote

25
Final Building Cost Estimate Development
1) Determine Base Price for Materials - Use of
RS Means data (updated quarterly) 2) Determine
Project Specific Factors - Project Location
(Remoteness and Economic Area) - Project Size
(smaller projects cost more) - Availability of
Contractors (fewer bidders higher bids) -
Current Economy (known market spikes) 3) Detailed
Quantity Take-off of Each Project sheet, by CSI
category. (14 Categories) 4) Estimate Validation
by Comparing to Previous Project Estimates. -
Three Intermediate Design Estimates Previously
Completed 5) Review Project Bids to Detect Trends
- Schedule of Values Comparison

Factors That Effect Cost

• Small projects
• Rural locations that have larger site development
  costs
• Storm water issues
• Structural Design Wind, Snow and Seismic
  factors
• Locations with a shortage of labor
• Features desired by the customer
• Shelf time The Departments escalation factor
  3.5 vs. CA building industry 7 - 10

28
Customer Options

• Remodel or build new
• Design for current operational needs or future
  needs
• Life expectancy (short vs. long)
• Low maintenance
• Lowest initial cost
• Aesthetic features desired in the project
• Use commercial available components/features or
  special designs

29
Basis For Designs

• DES designs to the customers needs, customer
  makes decisions on scope of work and features
• Designs must comply with the California Building
  Code, meet access compliance standards (ADA) and
  fire codes
• Designs conform with the design standards
  established by the program

30
Challenges

• Detailed description of scope of work in PIDs
• 15 projects in PSE development need scope
  reduction or increased funds.
• Dealing with inconsistent funding and low
  priority
• Modifying BEES after Final PSE
• Increasing the number of bidders.
• Target Bid Openings January - August

31
Summary

• Using forecasting data to improve estimates
• Estimates need to be updated more frequently
  after FPSE
• DES can design what ever you want
• DES can provide options and alternatives early in
  the PID or preliminary design process
• Designs must comply to codes
• Need bidder outreach to attract building
  contractors
