RECOMMENDATION:

It is recommended that the City Council authorize execution of Change Order No. 9 to City Secretary Contract No. 46954 with The Lane Construction Corporation, in the amount of $1,334,674.51 of federal grant funds, for reconciliation of construction costs of the Runway Extension Project Runway 16L/34R, Runway 16R/34L, and Taxiway Alpha Located at Fort Worth Alliance Airport which increases the total cost of the construction project to $64,684,063.22.

 
DISCUSSION:

On August 4, 2015, Mayor and Council Communication (M&C C-27409) the City Council approved the execution of a three-phase contract with The Lane Construction Corporation (Lane), in an amount up to $61,920,040.43 for construction of runway extensions for Runway 16L/34R, Runway 16R/34L and Taxiway Alpha at Fort Worth Alliance Airport. This project has been fully funded with federal grant funds.

Change Order No. 9 in the amount of $1,334,674.51 is the final change order for the Runway Extension Project. This change order reconciles the as-built quantities with the actual quantities over all three phases of the project. This change order also reflects additional expenses in the amount of $1,098,058.00 encumbered by the contractor due to working around an active electrical utility line that was necessary to remain in service to power the old Approach Llighting System Flashing Lights (ALSF) structure until the new ALSF equipment shelter was constructed. The utility line was not relocated in sync with the project schedule due to a failure by the utility service provider to mobilize in a timely manner. Change orders to date as percent of original contract:  4.46%.

Project expenses related to construction are summarized in the following table:

Phase I Construction$36,460,076.37
Phase II Construction$16,027,753.98
Phase III Construction$12,196,232.87
Total All Phases$64,684,063.22

Upon approval of this M&C, total project costs for the runway construction at Alliance will consist of the following:

Design Agreement & Construction Phase Services, Jacobs Engineering Group, Inc.$7,088,927.84
Construction Agreement Phase I - III, The Lane Construction Corporation$64,684,063.22
Total Project Costs$71,772,991.06

This project was substantially completed on May 2, 2018.

The following is a history of change orders that were previously approved for this project, either by City Council or administratively:

  • Change Order No. 1 was administratively approved in the amount of $46,635.03 for an alternative to the temporary duct bank system for the new Approach Lighting System with Sequence Flashing Lights building with a direct buried, armored cable.
  • Change Order No. 2 was administratively approved and reduced the contract by $11,653.06 due to a route modification to the power and communications cable for the Inner Marker to avoid directional drilling under the blast pad and to utilize existing concrete encased duct bank between Taxiway A and Runway 16R.
  • Change Order No. 3 (M&C C-27652) increased the contract by $633,304.83 for removal of unclassified materials, addition of materials to mitigate rain saturated soil to facilitate earthwork. Additional work included: pipe and structure to convey storm water, a 24-inch pipe for drainage, emergency re-cabling of the Runway 16L-34R edge light circuit and replacement of two Oncor manholes and the addition of a 5E6 duct bank and transformer switch foundation.
  • Change Order No. 4 (M&C C-27972) in the amount of $164,765.40 was comprised of changes to electrical specifications in the utility duct bank and ALSF building and paving panel/section replacement changes.
  • Change Order No. 5 (M&C C-28082) in the amount of $120,001.16 included work associated with Oncor utility relocation, airfield lighting, and new pavement at Runway 16R; additional pads to correct sloped floor of airfield lighting vault; additional heat shrink kits to terminate new airfield lighting fixtures; and additional rental barricades for a weekend closure.
  • Change Order No. 6 (M&C C-28228) in the amount of $495,664.00 included costs associated with Oncor utility relocation and duct bank: edge lighting revisions; elevation corrections; additional cable pulling; changes to size of duct banks for the runway end identifier lights, variance for irrigation plan; cost to install and remove RDR foundations from plan after RDR foundations were placed, and change in installation location of TB circuit at Taxiway H.
  • Change Order No. 7 reduced the contract by $107,797.65 due to a substitution of Soil-Cement Base for Lime Treated Subgrade, reuse of existing in-pavement Approach Lighting System with Sequence Flashing Lights, and relocation of a driveway on Eagle Parkway.  This change order was administratively approved.
  • Change Order No. 8 was administratively approved in the amount of $88,428.57 due to unknown utilities encountered in the work site, implementation of additional SWPPP measures, and additional excavation costs.

M/WBE OFFICE:  The Lane Construction Corporation agrees to maintain its initial DBE commitment of 23 percent that it made on the original contract and extend and maintain that same DBE commitment of 23 percent to all prior change orders up to and inclusive of this Change Order No. 9. Therefore, Lane remains in compliance with the City's DBE Ordinance and attests to its commitment by its signature on the Acceptance of Previous DBE Commitment Form executed by an authorized representative of its company.
