Answers to Bidder's Inquiries:

1. Where can a bidder find the ornamental onion "Allium X 'globemaster'"?

Allium X 'Globemaster'  is a non-native cultivar. Per the specifications, the roadside intersection plantings non-native cultivars are not required to be contract grown from stock obtained from the Trinity River watershed. Therefore, the Contractor is advised to search online for bulb suppliers that carry the specified species. Multiple online bulb suppliers have the species shown as available for purchase; however, if the species or quantity cannot be obtained the Contractor can submit substitution requests to the County for approval.

 

2. Plan sheets LD-1 and LD-2 have lists and numbers of plants. Do these numbers correspond directly with the numbers of plants in the bid items?

 

  • The (439) Bulb plants shown in the additive alternate planting palettes on Sheet LD-1 are rounded up to 440 on bid item # 150 Plant Group E (Bulb).
  • The (86) Treepot 8 container plants shown in the additive alternate planting palettes on Sheet LD-1 match directly with bid item # 151 Plant Group I (Treepot 8).
  • The (695) 1 Gallon container plants shown in the additive alternate planting palettes on Sheet LD-1 are rounded up to 700 on bid item # 152 Plant Group A (1 Gallon).
  • The (1080) Treeband plug plants shown in the Phase 2 Grassy Bioswale planting palette on Sheet LD-1 match directly with bid item # 33 Plant Group M (Treeband - Bioswale).
  • The (37) Treepot 8 container plants including Acer circinatum, Alnus rhombifolia, Prunus virginiana var demissa, and Populus trichacarpa, (see planting note 1 Sheet LD-2) shown in the planting palettes on Sheet LD-2 match directly with bid item # 114 (M) Plant Group I (Treepot 8) - Mitigation.
  • The (48) 1 Gallon container plants including Physocarpus capitatus, Rosa californica, Rubus ursinus, Vitus californica, and Cephalanthus occidentalis, (see planting note 1 Sheet LD-2) shown in the planting palettes on Sheet LD-2 match directly with bid item # 115 (M) Plant Group A (1 Gallon) - Mitigation.
  • The (80) Treeband plug plants shown in the Riparian Wetland planting palette on Sheet LD-2 match directly with bid item # 116 (M) Plant Group M (Treeband) - Mitigation.
  • The (25) Willow Cutting plants including Salix laevigata, Salix lasiandra, and Salix lasiolepis, (see planting note 1 Sheet LD-2) shown in the planting palettes on Sheet LD-2 match directly with bid item # 120 (M) Plant Group W (Willow Cutting) - Mitigation.
  • The 1,000 Treeband plug plants shown in the Enhanced Montane Riparian planting palette shall be included in the lump sum cost for bid item 117 (M) Plant Establishment Work – Mitigation as stated in the note below the Enhanced Montane Riparian plant palette Sheet LD-2 and in the Special Provisions Specification Section 20-9.03D(2).

 

3. Which plants are additive and which plants are in the base bid?

 

On plan sheet LD-1, The Upland Roadside seed palette, the Lowland Roadside seed palette, and the Grassy Bioswale seed and plug palette are part of the base bid and are included in the base bid as separate individual line items. All of the remaining plants listed on plan sheet LD-1 are part of the additive bid.

 

All plants listed in the tables on plan sheet LD-2 are in the base bid.

 

4. Are all of the plants for the entire job listed in the tables on plan sheets LD-1 and LD-2? Are there other plants required in other areas that are not listed in the tables?

All the plants for the entire job are listed in the tables on Sheets LD-1 and LD-2.  No other plants will be required; however, it should be noted that the treeband plug plantings shown on the Enhanced Montane Riparian plant palette sheet LD-2 are not included as an individual bid item. These plants (1,000 treebands in total) shall be included in the lump sum cost for bid item 117 (M) Plant Establishment Work – Mitigation as stated in the note below the Enhanced Montane Riparian plant palette Sheet LD-2, Planting Note 6 Sheet LD-2, and in the Special Provisions Specification Section 20-9.03D(2). All other plant container sizes are accounted for as separate bid line items in the bid schedule.

 


5.  Where is Item # 42 (210280) “Rolled Erosion Control Product (Blanket)” used on the project plans?

    This is the same item referred to in the following locations:

  •         On sheet 64 (DQ-5) as “Rolled Erosion Control Product (Blanket-Bioswale),
  •         On sheet 109 (LD-1) Detail 4 “North American Green C125BN Erosion Control Fabric or approved equal,”
  •         On sheet 109 (LD-1) “Phase 2 Bioswale Fabric Requirements” Table, and
  •         In the Specs Volume 1 page SP-39 (Add to Section 21-1.02O(4)).

    An approved equal is acceptable (though not stated in the specification).

6.  Over excavation quantities are listed in the project plans but there is no detail in the plans for over excavation?  Where is the over excavation, if any?

The over excavation for the roadway prism is not shown on the plans.  Over excavation quantities listed in the quantities table on Sheet 84 of the Project Plans are based on the Taber Geotechnical Study (October 2012) included in the information handout.  The designers have assumed the following to estimate the amount of over excavation that will be required:

The over excavation accounted for in the quantity tables was based on the areas provided by Taber.  A constant depth of 2’ was used for the areas within the station ranges of:

STATION RANGE VOLUME
STA 51+31.11 - 52+12.91 407.7 CY
STA 601+81.00 - 603+40.30 309.1 CY
STA 52+12.91 - 54+21.90 1,338.6 CY
STA 57+69.59 - 65+70.00 3,437.9 CY
STA 65+70.00 - 69+60.64 2,294.7 CY

       

These limits are approximate, and will be adjusted in the field based on the actual soil conditions.  The RE or geotechnical engineer on site should make the call as to what the exact limits of over excavation should be.

The over excavation quantities are included in the pay item quantities for roadway excavation.  Over excavation will be paid for as roadway excavation, as described in Section 19-1.04 of the Standard Specifications.
