Minimizing problems that cause design delays
Minimizing problems, and costs, that cause construction delays and claims
Multiphase rapid site investigation beginning before the record of decision (ROD) is signed. Note: this is site survey and project feasibility work, and not design work. Therefore, it can proceed prior to the ROD.
Work will focus on the following objectives:
|NOTE: The data collected and calculated, as outlined to the left, is not alignment or construction sequence dependent. It is a highly flexible approach, which will allow the rapid evaluation of multiple project scenarios. Also, this is not the total site investigation. It is only the work to BEGIN prior to the ROD.
New and existing utilities including storm water drainage are a dictating factor in design and construction speed. They can be as important of a design consideration as an earthquake in terms of cost and time.
|Problematic Soils for Pavement Subgrades (Including Expansive Clays & High Sulfate Content Soils)||
|Phasing of Work||Coordinate wall design/traffic control development||Have traffic section and wall designer involved at beginning of design process to insure that both are optimized to minimize redundancy in construction.|
Redundant or unnessesary walls for phasing of work add time to construction
|Reduction of the need for temporary and/or permanent walls saves time
Consider future loading conditions, road widening or park decks
|Require coordination meetings between traffic planning, wall designers and geotechs, early and often in the project.
Have independent review of plans at 30% and 60% design level for this issue.
|Failure to plan and design for future expansion of adjacent facilities causes additional construction delays in the future||Consider future plans (i.e.; structure support, wall removal, future expansion of parks) during design.||Discuss and coordinate with all related agencies (including DOT) to determine future plans in area.
Where feasible, design walls, bridges, and other facilities to handle these future facilities
|Insufficient/inaccurate ground survey can cause field modification of wall limits and redesign during construction||Obtain accurate survey and topographic information and accurately define wall limits and heights||
|Modification of wall foundations and details for changed conditions during construction causes delays||Obtain geotechnical data early in project and supplement as needed during design. (e.g.; High groundwater table, soft soils and contaminated soils)||
|Inclusion of aesthetic treatments can cause delays to construction if not well planned and executed||Aesthetic treatments may have a profound impact on wall design, detailing, and construction.||
|Efficient use of on-site materials can reduce waste and borrow||Large volumes of recycled concrete will be produced as part of this construction process and should be reused, if possible.||

(Barriers, Skill Set Coordination, etc.)
|1. Structure development report||Structure Types:
|Group bridges to maximize standardization.
Coordinate with Geotechnical/materials.
Consider manufacturing processes in design and construction.
|2. Bid contract at 30% complete||Designer prepares Bridge plans to 30% with quantities +-20%
Advertise and select contractor. Then contractor works with designer and owner to complete plans and construct project
|Innovative Contracting and Construction skill set coordination.
Implements partnering at very early stage to benefit owner, designer & contractor. Designer of record follows through entire project. Implements contractor's means and methods. Creates win/win/win situation for owner/designer/contractor.
Flexible for single or multiple contracts.
|3. Prefabricated construction||Pre-cast Substructure:
|Prefabricated superstructure units require match casting|
|4. Construction techniques that minimize traffic impact||Incremental launching: Build bridge at one end and launch across at desired location.
Lateral Slide: Build bridge adjacent to the existing structure. When complete, demolish old bridge and move new bridge into position
Balanced Cantilever ~ Segmental construction.
MOT / MPT
|Incremental launching does not interrupt underlying traffic. Work can be done over traffic or with minimal stoppages.|
|5. Temporary Bridges||Use prefab modular bridges for temporary structures or develop standardized modular bridges.||Reusable, multiple uses reduce cost. Cost could be amortized over multiple projects. When project is completed, give bridge to county or city for bridge replacement. Could also be stockpiled for future emergency or security use|
|6. Demolition of existing bridges||Use crushed concrete as select backfill for MSE walls||Requires coordination with Geotech/Materials|
|7. Advanced Foundation Contract||Based on BDR determine foundations that can be constructed ahead of time||Coordinate with geotechnical skill set, could save 6 to 12 months of construction time on large bridges|
|8. Pre-buy Beams||Have single designer develop all beam layouts and designs.
Then pre-buy all beams and supply them to the various contractors as needed.
|Beam storage versus hauling 100 miles|
|9. Preformed lightweight fill||Expanded foam blocks combined with fill to speed retaining wall backfill||Also suggested by Geotechnical.
Included in item 1.
|10. Thru Girder||Pre-cast segmental thru girder sections post tensioned together||Ideally suited to narrow structures where vertical clearance is an issue.|
|11. Corrosion protection strategy||Need corridor corrosion protection scheme||Included in item 1|
|12. Non-peak construction||Close and replace structure over a weekend.
(Friday 10:00 PM to Monday 6:00 AM)
Replace structure at night (7:00 PM to 6:00 AM)
|Coordinate with construction and innovative contracting|
|13. Move Interchange||Shift I30 / I35 interchange from split to a single location possibly above Houston St Viaduct||Disadvantage: Puts interchange above historic bridge ruining setting. Puts forest of columns in one of the proposed lakes of the Trinity Pkwy project. Impacts local access to city streets.
Follow up discussion was provided on reasons for rejecting this alternative earlier in the project development.
|14. Relocate UPRR1||Relocate UPRR away from downtown||Problems - requires cooperation of RR
NO good location to relocate to
Other side of Trinity is up for rejuvenation by City of Dallas, they would not like a RR there.
Moving very far impacts low income housing.
|15. Relocate UPRR2||Minimal shift in alignment to allow construction of new bridge parallel to the existing structure so that no temporary bridges are required||RR people tell us Stemmons RR Crossing needs to be 2 tracks -They propose shifting alignment to north and build new bridge on new alignment. We suggested using 300' trussCanyon crossing - existing pier is in center of HOV lane. Need to replace bridge- suggest using single span rather than multi-span for flexibility.|
|16. Durability||Design for durability, constructability, inspection and maintenance.||Select materials and develop details to enhance these concepts.|

(Barriers, Skill Set Coordination, etc.)
|Total or Partial Closure||Close portions of freeway for periods of time longer than just overnight, to allow faster completion||Requires alternate routes - Trinity Parkway & Traffic Mgm
Plan in place to finalize
Extensive PR campaign
|Environmental Constraints||Mill Creek must be raised before project can commence.
Trinity Parkway project planned in advance of Pegasus.
|ROD anticipated in 2007. This timing will affect choice of contracting methods.|
|Risk Management||Allocation and mitigation workshops||Conduct as precursor to development of RFP documents|
|Special Prequalification||Makes sense if D-B-B used.|
|Multi-parameter (A+B+...) Bidding||Bid both $ and time. Also, if applicable, bid traffic delay (differential travel time), quality, warranty, and other quantifiable parameters (A+B+C).||Delay, pay deducts. Improve, get a bonus. What about a good PR campaign, for instance, that reduces delay and allows the contractor to get a bonus? Also, what about delays related to accidents, fires, etc.?|
|Lane rental||Charge contractor for each lane closure|
|Lane assessment||Allow night closures, but assess stiff liquidated damages if closure time exceeded||Difficult to monitor, but does get attention|
|Incentives/disincentives||Incentives or disincentives based on:
Opening of new lanes;
Other open to traffic dates;
|Long-Term Warranties||Require warranties on specific elements of work (e.g. pavement life)
Consider not requiring minimums like AASHTO, as they might limit innovation.
|Acceptance by contractors is an issue. Bond to cover warranty is an issue, esal limits. Pay contractor later if warranty is not used? How to enforce warranty? Pay out from a retainage fund during warranty period. Might want to incorporate as part of other contracting method, e.g. Design-build.|
|Bid alternates||Alternates for items, or lump sum bidding|
|Third party agreements||Statutes allow or require agreements w/ utilities, etc. Also possibility to use contractor to do work then utilities pay|
|Raise Mill Creek in advance||Mill Creek needs to be raised, use as mitigation for other work.
Once this is done, there is more design freedom for highway
|Delivery Methods||Depends on timing. Single contract makes most sense|
|D-B-B||Design-Bid-Build: Traditional low bid||Considered second choice if alternative methods not feasible. If multiple construction packages used, get as much work done up front as possible (utility, alternate routes, etc.) before doing major construction packages.|
|Construction Manager||At-Risk Agency|
|Construction Manager/General Contractor||Contractor on board at PE phase, owner owns risk and design, but contractor helps with constructability||Viewed as a hybrid between D-B-B and D-B where contractor brought in at 30%. Use a GMP and adjust at final design.|
|Design-Build||First choice overall. Several possible variations: DBOM, Design-Build, Design-Build-Maintain w/ annual payments for performance, etc.||Entire project or pieces? Need coordination with other projects, e.g. Trinity Parkway
Construction group favors one large D-B contract. If not possible, then package low impact, up front portions (utilities, ramps, temporary structures) first, then do major project second.
|Tolls/Managed Lanes||Charge for access to some lanes - (not HOV, but general use) in order to subsidize the construction. Can incorporate variable pricing in order to manage demand/traffic flow.||Must cover cost of installing toll equipment, limiting access. May face public opposition due to perception of "Lexus lanes" benefiting higher-income drivers (especially since project occurs near low-income areas).|
|Public-Private partnerships||Private developer design, build, operate (maintain?) with reversion to state after payback and profit. Use of private equity could limit use of public debt to construct project.||Texas law may not permit concession. Public may oppose involvement by private contractor (making profit off of tolls on formerly-public highway, even if new capacity added).|
|Tax increment financing||City passes tax to fund portions of project directly benefiting or requested by city||City may have difficulty borrowing against tax increment (speculative source of revenue). Must identify district that will benefit from project.|
|Shadow tolls||Alternate means for paying contractor for construction and/or operation of project; based on road usage rather than completion or other metrics||Does not actually bring net new revenue to the table; basically an alternate method of paying for project, but does not directly reduce costs.|
|Other Federal Funds||Seek funding for economic development and other project elements from other federal agencies, including the Federal Emergency Management Agency (FEMA); Corps of Engineers; Housing and Urban Development, and any other eligible grants. City/County of Dallas would probably take the lead on identifying, seeking, and managing applicable grant funding.||Grant funding may be limited.|
|Joint development agreements||Develop some decks/lids and use proceeds to subsidize the construction of decks that do not have funding. Lease/sell ROW, where possible.||Must find suitable development opportunities activities (e.g., hotel above freeway). Cost of reinforcing deck/lid in order to carry the weight of a building may outweigh potential revenues from development arrangement. Must design fair process for development proposals/awards.
FHWA rules on program income may require proceeds to be used on Federal-aid eligible projects.
|TIFIA||Direct Federal Credit assistance under the Transportation Infrastructure Finance and Innovation Act; provides loans, lines-of-credit, and loan guarantees at an interest rate comparable to the interest rate on a Treasury bond of similar maturity. Loan repayment based on project needs, but can extend as far out as 35 years. Could be especially applicable to a joint-development opportunity with the city and/or with private developers. Comes "off the top" (no effect on Texas's Federal-aid funding).||TIFIA projects must be selected in national competition. DEIS must be circulated before application, and ROD or FONSI must be in hand prior to receipt of loan funds. City, county, and TTA could probably borrow at cheaper rates using existing bonding. (Developer may find TIFIA rates more attractive). Under current law, TIFIA projects must be at least $100 million (this project would easily meet this standard, as long as whatever element funded by the loan is considered part of the overall project). No more than 33 percent of eligible project costs can be covered by TIFIA loan (again, a standard that could be easily met if project is small component of $700+ million whole).
TIFIA proposal in SAFETEA would lower threshold for assistance to $50 million.
|State Infrastructure Bank and/or TIFIA||Low interest loans from state-capitalized bank. State can set terms, delaying repayment until up to five years after completion of construction, 35 years to repay, with low or no interest.||Depending on funding available from Texas SIB, could be useful for financing smaller pieces, e.g. city improvements, etc. Could be particularly useful for spreading out city contribution to project over time. Reduces city/county need to issue debt.|
|GARVEE bonds||Issue bonds against future federal funding - TxDOT law now allows borrowing in anticipation of Federal funds.||Policymakers must determine tradeoff between current investment and future repayment; cost of interest should not outweigh benefit of achieving project sooner. Other areas may perceive borrowing solely for Dallas area project as unfair.|
|Performance Specifications||Specifications requiring end-result or performance rather than exact methods||Used either in conjunction with Design-Build, warranty, or other methods, or alone.|
|Contractor developed Traffic Control Plans||Department sets performance requirements and contractors develop detailed plans||May be more problematic if multiple construction contracts used, but still possible to develop in framework of an overall traffic management plan.|
|Pre-set pricing for COs||Set a framework for pricing change orders, for extended time.||Allows predetermined pricing for change orders, but may result in higher contingency or overhead in general.|
|Delegation of Authority for Cost to field||Speed decision making, keep job moving|
|Partnering/escalation agreements||This is standard procedure for TXDOT but the team would like to add and support its use.|
|Bid escrow||Contractor puts all notes and calculations in escrow, in event of later disputes. Allows owner to see thinking at time of bid.|
|Cash Curves||Use CPM to create cash flow curve; avoids over-extension of budget by tying payments to available revenues||Need to ensure that cash payment schedule does not deter rapid completion.|
|Bonding requirements||Consider changing bonding requirements so that more contractors can participate - bonding on high dollar projects can be difficult to get. Consider dynamic allocation of risk: at any one time, less than 100 percent of the project is at risk, so bonding requirement can be less than 100 percent. In CO, bonding requirement was set at 50% for parts of T-Rex||Need to balance lowered bonding requirements with protecting DOT against risks of non-completion (retainage or other strategies).|
|Risk Management/assessment||Develop explicit matrix to define risk and who owns in advance, to assign appropriately, and to determine where risk can most advantageously be held.|
|Change Retainage requirements||Lower retainage requirements so that there is not a large amount of cash withheld, so that bids may be lowered appropriately||If necessary can increase retainage if problems are anticipated|
|Set up allowances for contingencies expected in contract||Cover unknowns in advance, to limit bid amount||Owner, or project manager, owns authority to use contingency|
|Set up one TXDOT project management team||Single team manages project, using perhaps consultant help. Set up dedicated testing facility, if not Design-Build. (Design-Builder would handle if D-B). Team deals with configuration, cost, schedule, CO management, etc.||For D-B, team would delegate more responsibility to contractor and deal with higher level mgmt. issues.|
|Utility Coordination Contract||Either in conjunction with design-build contract or separately, hire external utility coordinator to identify, locate, coordinate, and negotiate agreements with all utilities in corridor. Manage information exchange between DOT and/or design/build contractor - so as design evolves, utility relocation is adapted. With utilities, engineer conduit that combines utilities, and lay out construction schedule that goes in logical order. Successfully pioneered in the Texas Central Expressway. Cost of licensed utility inspector can be included as part of contract cost.||Utilities in Texas have a statutory right to occupy ROW; process is "first-come, first-serve." Utilities may not be willing to let work be done by contractor, or may insist on use of own contractor.
Optimal solution may be conduit; cost of conduit could be covered by lease payments from utilities, but lease payments could be very difficult to negotiate.
|ROW Acquisition Contract||Incorporate ROW acquisition into design-build contract; saves time by eliminating levels of decision-making - e.g., administrative settlements can be approved by giving contractor latitude to approve up to certain level; design issues can be resolved and ROW agreements made more quickly; contractor will acquire ROW rapidly due to incentives for timely completion in contract.||Works for parcels that can be acquired without legal action; DOT/contractor must allocate risks for parcels that cannot be acquired.
Can TxDOT legally contract out for these services?
|Owner Controlled Insurance Program (OCIP) or Partner-Controlled Insurance Program (PCIP)||Wrap up insurance, so that DOT obtains overall insurance for project (or shares with Contractor), and bills contractors for premiums, eliminating need for individual contractors to seek (average savings of 2%)||Inspector General criticized Central Artery project for maintaining excessive reserve funds for its OCIP|

Want someone to investigate
Benefits may eliminate some problems
|- Design exceptions to support this
- Wall height reduced and increased bridge height, less earthwork

(Barriers, Skill Set Coordination, etc.)
|20 Years little to no maintenance. Expected pavement life more than 50 years.||This should be a low maintenance roadway with no base failures expected and surface failures experienced very infrequently.||Should be coordinated with materials, and construction technical experts|
|Composite pavements should be considered.||Various scenarios should be considered such as asphalt base\with CRCP on top (normal practice), CRCP on bottom with asphalt on top, precast/prestressed slabs with asphalt on top (at intersections and frontage roads, etc.). It is also possible to diamond grind slabs and not top with asphalt. If grades can be adjusted we can leave the existing pavement in place and bury it.||Composites get the benefits of the structural capacity of the concrete and the noise and ride of the asphalt. The asphalt insulates the concrete from temperature and moisture fluctuations. SMA with modified asphalt and open-graded friction courses should be considered as surface courses. Construction and materials experts should be consulted.|
|Materials selected to provide for quality product. Recycling of old concrete pavement should be maximized.||Do not use siliceous aggregates. Fast track material testing techniques should be used. Set up a separate pay item for curing to get a better quality product.||Subsurface investigations must be done. Consider more restrictive specifications to get higher quality materials. Coordinate with geotechnical and material testing groups. Possible uses of recycled pavement could be behind retaining walls, asphalt base courses, crushed aggregate bases, etc.|
|Staging areas (crushing operations, concrete plant, etc.) should be on project site if at all possible. Permits obtained before letting.||On-site plant operations significantly reduce construction costs by eliminating haul distance and significantly reduces construction related traffic from surrounding roadway network.||If the floodplain is considered for plant operations, coordination with FEMA and COE will be required. Plant permits may be obtained by TXDOT in advance if the plant sites are designated on the plans. Protection of plant equipment and maintaining flow capacity through the floodplain are considerations. Right-of-way and environmental section should be consulted.|
|Restrict traffic through canyon section.||Consider such techniques as restricting all lanes to HOV traffic (reduction of lanes), weekend closures, complete shutdown.||TEXDOT traffic engineer should be consulted as well as environmental section. Could be publicly controversial and formal notification procedures would have to be carried out. This would affect environmental clearance. This could significantly expedite construction. HOV traffic can remain on a limited number of lanes while the others can be reconstructed.|
|Performance characteristics should be specified, regarding smoothness, friction, distress, noise, etc.||Performance warranties require detailed stress identification with monitoring cycles and techniques.||Distress has to be tied to existing pavement characteristics in a State or location. Also tied to typical deterioration curves and be truly measurable characteristics.|
|Long term warranties with contractor responsible for maintenance.||Long term performance warranties requiring contractor maintenance for approximately 10 years||This would require design build and tied with innovative contracting practices. Likely to result in innovative design and construction practices. Coordinate with contract administration specialists.|
