Increase in cost justification:

The Partial GMP of $44,687,897.67 included in this administrative memorandum compares to an estimated cost of $31,300,000.00 included in the Program Cost. Increased costs were incurred due to:

• Transfer of 3,000 linear feet of 90-inch pipe from the raw water pipeline
• Increased depth to allow future transfer of Texoma raw water via gravity
• Raising of the embankment for better control of overflow
• Increased excavation in rock

Action Items

E. Consider recommendation on authorizing execution of a post- termination, final payment, and release agreement and authorization to issue final payment to Ratcliff Constructors, LP, in the final payment amount

• f

$181,974.95 and ($9,795,025.05) credit for termination of contract, on Project

• No. 101-0352-14, Wylie Water Treatment Plant Water System

Operations Center (Please refer to Administrative Memorandum No. 5416)

AGENDA

17

WATER SYSTEM OPERATIONS CENTER

18

• Initial construction contract awarded to Ratcliff in May 2018
• Construction delayed due to unanticipated permitting and zoning

complications; extreme detrimental impact to the Contractor

• By contract, Contractor can terminate and seek recovery for legitimate

costs incurred:

• Ratcliff labor costs for:
• Development of shop drawings (rounded)

$56,742

• Project management and

$72,722 supervision

• Structural steel from Russellville

$52,511

• Total

$181,974.95

WATER SYSTEM OPERATIONS CENTER

19

• Nature of the raw steel procurement agreement between Ratcliff and

Russellville did not lend itself to clean re-assignment to NTMWD, for subsequent assignment to new contractor.

• Re-assignment of materials between contractors presents potential for

many liabilities to pass to Owner

• Final payment of $129,464 to Ratcliff will settle all claims against the

current contract

• Final payment of $52,511 to Russellville accounts for incurred cost for raw

steel, detailing fees, restocking credit and scrap credit.

• Total out-of-pocket for termination and release is $181,974.95.

J. Consider recommendation on adoption of Resolution No. 19- 29 authorizing use

• f

competitive sealed proposal procurement method under Texas Government Code, Chapter 2269, for the Wylie Water Treatment Plant IV Filter Gallery Wall Structural Evaluation, Project No. 101-0422-16 (Please refer to Administrative Memorandum No. 5404)

AGENDA

37

PLANT IV FILTER REPAIR – CSP PROCUREMENT METHOD

38

• Authorize use of Competitive Sealed Proposal (CSP) procurement

method

• Selection based on qualifications rather than low bid pricing alone
• Recommended due to complexity of repair methods and project

staging

• Repairs will involve multiple shutdowns and mobilization across

several years, in order to maintain critical plant operations

• Contractor qualifications and experience will be critical factor in

successful project performance

PLANT IV FILTER REPAIR – CSP PROCUREMENT METHOD

39

Chapter 2269 of Texas Government Code allows NTMWD to elect to use alternate procurement methods such as CSP for construction projects. Legal counsel has advised of statutory need for NTMWD Board to specifically elect to utilize alternative delivery for each event.
