THE OWNER’S PERSPECTIVE

OWNER’S PERSPECTIVE: San Diego Community College District
Three Colleges - City, Mesa and Miramar Six Continuing Education Campuses Students – 150,522 in Academic Year 2007-2008 Employees – 4,900 District Square Footage – 2,218,031 $1.555 billion Propositions S and N construction bond program

OWNER’S PERSPECTIVE: Why Use Lean?
Traditional delivery is NOT working. All parties are interest-based rather than project-centric. We continue to spend inordinate amount of time on change management, which is wasteful. As a public agency we are stuck with lowest responsive, responsible bidder regardless of p past performance p history. y

OWNER’S PERSPECTIVE: What Can I Get For My Money?
Reduce Waste/Inefficiency
Manufacturing
Construction Lags Behind Other Industries Redesign g Rework Claims/Litigation Improper Sequencing of Work
Construction
Delayed Submittals and Approvals Image Space

OWNER’S PERSPECTIVE: Design Build California Community Colleges
As of January 1, 2008, Community Colleges can use design build under SB614. Must be at least $2.5M in value Requires project-specific Board resolution
Need to evaluate the project based on five minimum criteria. Price (10%) Technical Experience (10%) Life cycle cost over 15 years (10%) Skilled Labor Force (10%) Safety Record (10%)
7
OWNER’S PERSPECTIVE: Why Use Design Build?
Advantages: Qualifications-based selection with consideration of price. Match firm past experience and performance with project need. Greater opportunity to select project manager and superintendent. Save money by consolidating CM owner agent, general conditions and supervision into one contract. Best value with target budgeting g order rates. Historicallyy lower change 8
OWNER’S PERSPECTIVE: Integrated Project Delivery (IPD)

OWNER’S PERSPECTIVE: IPD – What is it?
Project delivery approach that integrates people, systems business structures systems, structures, and practices to optimize project results, increase value to the owner, reduce waste and maximize efficiency of project delivery. Distinguished
by highly g effective collaboration among the owner, prime designer and prime constructor commencing at early design through project completion.
10
OWNER’S PERSPECTIVE: IPD – Why do it? Integrated Design An integrated design process allows decisions to be made early when the opportunity for change is maximized and the cost of the changes are minimized.

OWNER’S PERSPECTIVE: Target Costing
12
OWNER’S PERSPECTIVE: BIM! BIM! BIM!
Build it in model space before you build it in real space. Reduce conflicts using Revit and NavisWorks clash detection. Energy efficiency evaluation. Walk the end user through the space. With schedule integration, a 4-D model can be developed. developed With cost estimates, a 5-D model can be developed. p 13
OWNER’S PERSPECTIVE: Design Build with Elements of Lean City College General Classroom / Parking Structure Project. Elements of Integrated Project Delivery Building Information Modeling List/prequalify all major trade contractors List/prequalify all major engineering consultants Target Budgeting
11 proposals received; top p 5 teams shortlisted for interview.

OWNER’S PERSPECTIVE: Design Build Proposal Evaluation Factors
Price (20%) – 200 points total Proposer’s Proposer s Price = General Conditions Cost + (OH&P% X $37 $37,750,000) 750 000) Lowest Proposal Price times 200 the Proposer’s Price
Non-Price Factors (80%) – 800 points total Technical Expertise (300 points) Life Life Cycle Costs (100 points) Skilled Labor Force Availability (100 points) Commitment to Diversity (50 points) Safety Record (100 points) Design Excellence (150 points)

OWNER’S PERSPECTIVE: Design Build Proposal Evaluation Factors Technical T h i lE Expertise ti (300 points) i t ) General Firm Information Firm Experience p Team Member Experience Firm & Team References
Life Cycle Costs (100 points) First cost, estimated life, annual maintenance cost, operation cost and projected replacement timeline for: Mechanical systems Electrical systems Vertical transportation
Energy consumption based on 40 year project life escalated at current CPI CPI. 17
OWNER’S PERSPECTIVE: Total Cost of Ownership Example
50 year design life 100,000 square foot classroom building Design and construction cost - $30 million Capital Renewal: 2 percent of current replacement value (APPA benchmark) O&M Budget $5.69/square foot Inflation: 3 percent

OWNER’S PERSPECTIVE: Savings in O & M Capital Renewal
Total Cost of Ow nership
11%
Save 5% in Cap. Renewal 53%
D&C: Cap.R: O&M: Total:
$30M $101M $149M $280M
Savings Total NPV $ 5M $1.1M $15M $3.4M $20M $4 4M $4.4M

OWNER’S PERSPECTIVE: Green Building Policy Implementation: Methodology
Incorporate life-cycle costing that includes initial construction costs, operating costs, maintenance repair and d replacement l t costs t to t evaluate l t the th long-term l t investment value of design alternatives. Integrated I t t dd design i so th thatt b buildings ildi systems t are designed d i d to perform as a whole rather than as component parts with an emphasis on efficiency and performance. Perform enhanced commissioning and facility performance evaluations to assure that the building s stems meet the occupant systems occ pant req requirements irements and design intent.

BUILDER’S PERSPECTIVE: Approach to Risk Management
Management of the Process Building Information Modeling (BIM) Risk Management g
Last Planner Scheduling
23
BUILDER’S PERSPECTIVE: BIM (Building Information Modeling)
BIM allows Sundt to Work with Designers and Sub-Contractors in a Collaborative, 3D Environment During Design and Construction Benefits Fewer RFIs Fewer Change Orders Fewer Delays
24
BUILDER’S PERSPECTIVE: Internal Clash Survey
Building Construction Mechanical piping hits cable tray and fire protection t ti piping i i iin ceiling ili space Survey Average Results Man-hour Man hour Savings = 61 Delay Savings = 3 Days Cost Savings = $30,349.00 Number of Clashes Shown in Example = 9 Savings per Clash Resolved = $3,372.00
25
BUILDER’S PERSPECTIVE: Why Use BIM?
Average Savings Per Clash Resolution
$5,934.00 3 Days 59 Man-hours
