1 Portway Extensions Concept Development Study Final Report APPENDIX F PRELIMINARY CONSTRUCTION COST ESTIMATES

2 Portway Extensions Concept Development Study Final Report In advance of an economic impact analysis to be conducted as part of the next stage of the Portway Extensions program, preliminary construction cost estimates were prepared for the roadway infrastructure improvement concepts presented in Section X of this report. The cost estimates follow the NJDOT preliminary estimation procedures. Following is a summary table of the infrastructure improvement costs (exclusive of any required right-of-way acquisition or extensive environmental remediation that may be required). Also presented are the computation sheets detailing the construction items, estimated quantities and unit costs for each recommended alternative concept.

For skews over 6 degrees it will be necessary to make a special analysis and establish a square foot price comparable to above. 2. For very bad foundation conditions requiring unusual lengths or spacing of piles, it will be necessary to establish a square foot price. 3. For longer spans, adjust the cost per square foot to reflect increased cost of structural members. 4. For span bridges, it is expected the length of the side span will be in- creased in proportion to any increase in height. Because of the resultant increase in deck area, the square foot price will remain approximately the same in the range of heights shown. For extremely high structures (particularly for viaducts), square foot prices will have to be increased. 5. For structures over 4 foot long (viaducts), reduce the cost per square foot if repetitive span length and forming can be used. Reduce by $.5 for lengths from 4 to 6 feet and by $1. for lengths over 6 feet. (Do not forget adjustments (3) and (4) above on viaducts). Northern Extensions Page 4
