Contract No. T200712003.01 JAMISON CORNER ROADNew Castle County

Ladies and Gentlemen:

Enclosed is Addendum No. 1 for the referenced contract consisting of the following:

1. Ten (10) pages, Bid Proposal Forms, pages 1 through 10, revised, to be substituted forthe same pages in the Proposal.

2. Three (3) sheets, Construction Plans, sheets 4, 12 and 33, revised, to be substituted forthe same sheets in the Plan Set.

3. For proposal holders with the electronic bid option only, Amendment Disk No. 1.

Questions and Answers:

1. Please clarify the intent of note 7 on sheet 33 of 48 of the plans. Is the limitation of jointsno closer than 4' from the weir-notch section to mean the center of the notch? If not, thecenter sections of the Southern pond weir wall will be 24' long, 11'-3" high and 9'wide…and weigh almost 38 tons. The center of the northern pond weir would be 22 tons.Please clarify the intent of the note. Sections of that size will be extremely difficult tomanufacture, and even more difficult to ship (and costly).

It is acceptable to have joints within the weir-notch section of the wall. Joints shallnot be located within the V-section of the weir.

2. Specs call for a minimum of 4 post tensioning strands to connect sections of the weirwalls together. Given the deep notch at the center of each one, it seems this may not bepossible or cost-effective. We request that (2) strands would be more efficient, bothbeing centered in the stem portion.

Two (2 ) post tensioning strands are acceptable for the weir walls.

3. Would mechanical rebar splicers, cast into the top slab of the rigid frame, be anacceptable alternate for the extended reinforcing shown in the "parapet and headwall

section" on sheet 27 of the plans? We would supply threaded rebars to match up withthe splicers, ship them to the jobsite with the precast for installation by the contractor.

Mechanical rebar splicers/couplers may be used in lieu of the long extended rebarsin the parapet and headwall sections.

4. DI-1 that is shown on plan sheet 12 is too small to accept a 19" x 30" rcp. Please clarify.

Addressed in Addendum No. 1.

5. Should there be a fuel escalation clause for this contract since NTP is 24Oct2011 andwith a 278 calendar project? There is approximately 375 days of exposure that we haveto deal with in guessing what fuel costs will be.

No, a fuel escalation clause is not required for this contract.

6. Does DELDOT have a disposal site for excess dirt for future use on 301 projects?

Addressed in Addendum No. 1.

7. Where is bid item 760000 used on this project (location)?

Item 760000 (Pavement - Milling, Hot-Mix) is used on the existing bridge and itsapproaches. Please see sheet 12 of construction plans.

Please note the revisions listed above and submit your bid based upon this information.

Sincerely,
