FACILITY SECURITY and ACCESS REQUIREMENTS

The Washington Aqueduct has been designated a Critical Infrastructure Facility under the National Critical Infrastructure Program which was outlined in Presidential Decision Directive 63. All Contractor and sub-contractor personnel must consent to a review of public records and screening of personal background information before access is granted to the McMillan Water Treatment Plant. Failure to provide requested information may result in denial of access to facilities. No information will be released to outside agencies. The following major types of adverse information may exclude a contractor, his employees, or sub-contractors from gaining access to Washington Aqueduct property. Each case will be reviewed on its own merit:

a) Illegal use or abuse of drugs or alcohol, theft or dishonesty, unreliability, instability, use of force, violence and weapons related incidents that indicate a general disregard for the law.

b) Aberrant, deviant sexual behavior or bizarre sexual conduct. Contributing to the delinquency of minors, child molestation, and/or rape. Records or testimony of employment, education or military service where the individual was involved in serious offenses or incidents that would reflect adversely on the honesty, integrity, trustworthiness, or stability of the individual.

c) Excessive indebtedness, bad checks, financial difficulties or irresponsibility.

d) Failing or refusing to sign the proper authorization documents to conduct the background screenings.

e) Knowingly providing false information on Official Government Documents.

f) Contractors must ensure that employees are legal residents of the United States and supply that proof.

g) Involvement with known terrorists, terrorist organizations, terrorist-supporting financial organizations, subversive organizations or individuals who advocate violence or the violent overthrow of the US Government.

Government or contracted personnel may be working in and around the McMillan North Clearwell Gatehouse during periods when the Contractor is providing service. Contractor’s work shall not unduly interfere with Government personnel or other contractors’ work in the area, and the Contractor shall maintain safe access to the building and surrounding areas at all times. Under certain emergency situations, the Contractor may not be granted access to the McMillan Water Treatment Plant or the North Clearwell Gatehouse Building.

The Contractor shall provide and maintain within the construction area minimum field-type sanitary facilities approved by the COR as stated in the EM 385 1-1 (03 Nov 03), Section 2. Government toilet facilities will not be available to Contractor's personnel.

This structure is located over a finished water storage tank and therefore, no hazardous material including, but not limited to, fuel, oil and other chemicals unsuitable for use with finished drinking water will not be allowed inside building or on top or the clearwell.

The contractor shall not drive vehicles of any size on the grassy area surrounding the clearwell gatehouse structure. The top slab of the existing clearwell is not designed to accommodate vehicular loads. The contractor shall also not stockpile construction material (brick or other related materials) in the clearwell gatehouse or on the top of the clearwell. Proposed loadings to the existing clearwell top slab shall be included as part of the Contractor’s Work Plan, to be sealed by a licensed Professional Engineer.

Storage and staging areas shall be as directed by the Contracting Officer. No materials or equipment shall be stored on the clearwell.

SUBMITTAL DEADLINE

You are requested to submit your RFQ by 12:00 p. m on December 21, 2012. This Request for quote (RFQ) is not a Notice to Proceed (NTP).

SECTION 00700 - CONTRACT CLAUSES

The following have been added by full text:

QUESTIONS AND ANSWERS

Question No. 1:

Please clarify how the bid is to be submitted. Item #2 on the solicitation is not marked as either a sealed bid or a negotiated bid. The price schedule calls for a lump sum price for the entire contract and leads me to believe that this is a sealed bid. However page 9 of the solicitation calls for a breakdown of prices for anything over $2,000. This points to this as being a negotiate bid.

This needed to be clarified as it is very unusual that the USACE would request a lump sum price with a breakdown of the lump sum price required. Also please specify the basis of award for this contact.

Answer No. 1:

See the attached amendment and the basis for this contract will be Request for Qutoe (RFQ).

Question No. 2:

The Scope or work and the contract sketches refer to the roof support system as a truss system however after the site visit it appears as if the roof is not composed of individual trusses but of a joist and rafter system. Please advise as what type of roof support system is in place as these two options are very different in nature.

Answer No. 2:

The rectangular building consists of a timber truss framed hip roof supporting a clay tile roof with an approximate 8:12 pitch. The timber trusses are spaced at varying dimensions ranging from approximately 2’-3” o.c. to 2’-8” o.c. The trusses bear on all four of the exterior walls with the hips bearing at the building corners with no interior bearing supports.

Question No. 3:

During the site visit it was noticed that there are many pipes, conduits, and instrumentation devices that run along and perpendicular to the wall that has the crack in it. These pipes and conduits also run along the ceiling and the other walls of the structure. According to the USACE personnel on site these existing conduits, pipes, and instrumentation equipment need to stay in service at all times and modifications to them are not part of the contact. By repairing the walls and realigning them, there would need to be disruption in service to these items. In addition the pipe and conduits are ridged and run perpendicular to the walls that are to be realigned. By realigning the walls the distance between the walls will decrease or increase, however the conduits and piper are to remain untouched and keep the same distance. Please note that at least one of the conduits, installed in the securities upgrade contact, was installed after the walls shifted and potentially all of the conduits were installed after the walls shifted. Please advise.

Answer No. 3:

See attached amendment.

Question No. 4:

Is it possible to get a copy of the sign in sheet for the site visit?

Answer No. 4:

See attached document for A copy of the sign in sheet for the November 27, 2012 site visit.

Question No. 5:

Will additional site visits be allowed.

Answer No. 5:

See attached amendment.

The following have been modified:

52.236-27 SITE VISIT (CONSTRUCTION) (FEB 1995)

(a) The clauses at 52.236-2, Differing Site Conditions, and 52.236-3, Site Investigations and Conditions Affecting the Work, will be included in any contract awarded as a result of this solicitation.
