City of Midlothian• Ellis County, Texas
• Population ‐ 16,000 residents
• Strategically located equal distance from Dallas and Fort Worth• Strategically located equal distance from Dallas and Fort Worth –25 miles southwest of Dallas and southeast of Fort Worth
• 2006 Long Range Water Supply and Master Plan – projects population to steadily increase over the next 20 years
• Existing Tayman WTP production capacity of 13.0 MGD
d d• Current water demand is 10.0 MGD
• Projected water demand is 36.5 MGD
Midlothian WTP Project Profile
• The Tayman WTP is completely build‐out
• New WTP to meet future demands and provide redundancy
• Membrane Filtration facility
• FundingTWDB Drinking Water SRF + City Funds = $30 0 M– TWDB Drinking Water SRF + City Funds = $30.0 M
– Engineering = $4.2 M
– Funding Available for Construction = $25.6 M
• Owner Preferences– Maximize local construction participation
– Operators involved in design/pre‐construction phaseOperators involved in design/pre construction phase
– Desire for qualified contractor with experience
• Projected water demand may exceed available capacity in summer fof 2012

Typical CMAR Services
• CMAR assumes the risk of construction
• Providing suggestions on constructability, risk management, and materials during preconstruction.
• Preparing bid packages for the procurement of Subcontractors and Suppliers, including the Membrane Filtration System
• Preparing overall project schedule and updates.
• Preparing Opinion of Probable Construction Costs (OPCC)
• Guaranteeing the construction cost.
Profile of a CMAR Project
• Complex project, difficult to define or subject to change.
• Tight/limited budget or sensitive financial controls
• Tight schedule, fast tracking desired.
• Better risk management desired.g
• Builder selection flexibility
The Midlothian WTP #2 fits this profile

Solicitation of a CMAR
• Request for Proposal– Scope: Project should be reasonably well defined.
– Selection/scoring criteria
– Experience
h d l– Schedule
– Budget
Other information to support selection of CMAR– Other information to support selection of CMAR
• One or two step selection process required. Midlothian selected the one step processselected the one step process.
One Step/Two Step Process
• One Step Process– All qualification and fees are requested
– Fees include preconstruction, general conditions, bonds, and contingencies
Evaluation based on qualifications and pricing simultaneously– Evaluation based on qualifications and pricing simultaneously
• Two Step ProcessFirst step: Select maximum 5 proposers on the basis of– First step: Select maximum 5 proposers on the basis of qualifications (non‐monetary criteria) only.
– Second step: Request full proposal only from shortlisted proposers.
– Evaluation based on qualifications first, then pricing
Scoring Processff h d f l• One effective method for evaluation is using a scoring
matrix based on weighted criteria and point scale
I iti l i d i d d tl d ith t• Initial scoring done independently and without knowledge of the preconstruction fees
• Owner/Architect/Engineer Due Diligence• Owner/Architect/Engineer Due Diligence– Reviews: Financials stability, personnel and reference checks
• Set up a workshop:• Set up a workshop:– Compile scores
– Open fees and score the last criteriaOpen fees and score the last criteria
– Reevaluate scores based on financials
• Determine if interviews are necessaryetermine if interviews are necessary– Revisit scores based on interviews.
Midlothian CMAR Scores
Guidelines for Interviews
• Short list to top contenders, release the rest.
• Establish a set of standard questions
• For the benefit of the CMAR– Provide adequate time for CMAR to prepare.
ifi b i f h i i– Be specific about expectations for the interview.
– Make the sessions informal and relaxed.
• Set aside time to discuss the collective results after eachSet aside time to discuss the collective results after each interview.
• Document reasons for scoring changes ‐ be able to defend g gscores.
Selection and Contract
• At the completion of interviews– Review and revise scores as necessary
– Make final decision on CMAR for recommendation to Board or City Council
P bli h lt f l ti ithi 45 d• Publish results of selection process within 45 days
• Notify TWDB (funding agency) of recommendation
f h l d f d b• Notify the selected CMAR firm and begin contract execution process
P t ti i b i t t ti• Preconstruction services begins on contract execution date and ends after GMP is established
Proposal Evaluation Flow Chart
CMAR = DBB
• Owner retains design professional as their advocate and trusted advisor.
• Advertisement and solicitation process allows everyone to compete on “Best Value”.
• Includes safeguards of accountability and transparency.
• Price is known before construction begins.
• Single point of responsibility for construction.
• Contractor/Builder is at risk for cost overruns and errors.
CMAR ≠ DBB• Collaborative team with Owner, A/E and CMAR – vested interest
• More control in the selection of Builder/Contractor. Allows negotiations with top ranked firms.
• Costing is “open book” and allows owner to participate in setting price.
• Ability to effectively “fast track” construction.
• Contingency is owned and managed by Owner
CMAR Myths
• No Construction Inspection required
• Less qualified Construction Inspector is acceptableq p p
• No change orders during construction
G t t t i t th O• Greatest cost savings to the Owner
• CMAR projects have shorter schedules
Take Away Points
• Assess the project and determine if alternate delivery is beneficial
• Solicit and procure CMAR in accordance to state rules and regulations
• Owner must provide inspections materials testing and• Owner must provide inspections, materials testing and verification inspections independently of CM
• Bonds are requiredBonds are required
• Specify the point at which the Guaranteed Maximum Price will be set in the RFP.
• CM recommends, Owner selects subcontractors and suppliers.
