GENERAL NOTICE TO

CONTRACTORS

A minimum of 25% of the work to be performed on this project shall be performed by the Bidder in accordance with Texas Local Government Code Annotated §262.025 and 271.055.

A Bidder who submits an Unbalanced Bid may be disqualified and the bid may be rejected.

An unbalanced bid is a type of bid that contains lump sum or unit bid items that do not appear to reflect reasonable actual costs plus a reasonable proportionate share of the Bidder’s profits. An example of an Unbalanced Bid is one in which a bidder places an unreasonably high value on certain items in a unit price contract and an unreasonably low price on other items within the same bid. This is done for purposes of receiving large payments at the beginning of a contract or for maximizing profits on items that will be used in a contract in greater quantities than estimated in the bid document, and underpricing items it believes will be used in significantly lesser quantities.

Unbalanced bidding is also known as loading of rates.

If the award of the contract containing an Unbalanced Bid would result in an advantage to the contractor with a corresponding disadvantage to the District; produce a reasonable doubt that Award to the low Bidder at issue would result in the lowest ultimate cost to the District; or if the competitive bidding process is jeopardized, then appropriate steps must be taken by the District to protect the public interest. In such instances, the District shall deem the Unbalanced Bid as non-responsive.

At the time of bid, the contractor shall submit a detailed project execution plan, or methodology, that discusses principles, practices, and procedures to be used by the vendor in implementing associated work for this project. The information should include, but not be limited to, a discussion of design services, project mobilization, use of subcontractors (if applicable), a project organization chart, project manager identification, quality assurance program, safety record, and reporting capabilities.

a. Project mobilization means the time required to have a team in place at the job site once the Purchase Order has been issued, and identification of which skills would be performed by the vendor and by any required subcontractors,

b. A project organization chart should detail the team to be assigned to Harris County. The organizational chart shall show the chain of command, and the role and responsibility of each member. (The vendor shall keep Harris County up to date with a revised organization chart each time there is a significant change), Resumes of key personnel that will be dedicated to the project. Resumes should demonstrate completion of at least two (2) similar projects within the last two (2) years.

c. Vendor must provide Harris County with a quality assurance program that ensures, at a minimum, the following:

1. Utilization of proper materials,

2. Utilization of satisfactory workmanship,

3. Correction plan if unsatisfactory materials or workmanship is utilized,

4. That all necessary paper work, drawings, and documentation follow the job from start to finish and ensure compliance with construction documents approved submittals, request for information (RFI) and change in contracts (CIC),

5. That entire job is complete on time as mutually agreed, and to satisfaction of Harris County, 2/2 General Notice to Contractors

d. Fiscal and Bonding Capacity:

1. List your aggregate bonding capacity

2. List your total annual billings for each of the past five (5) calendar years,

3. Supply financial references, On public works projects, all contractors shall supply a list of all suppliers and subcontractors with addresses and phone numbers, prior to work commencing.

At the time of the scheduled preconstruction meeting, the successful bidder shall supply to the District a list of representatives, signed by an Officer of the Company, who are authorized to sign official documents, i.e., Purchase Orders, Change Orders, Final Estimates, etc.

HCFCD is using an internet-based Project Lifecycle Management Solution, Oracle’s Primavera Unifier® (Unifier), to maintain consistent administrative and technical control for all projects throughout the County. The Contractor is required to utilize Unifier on this project in accordance with procedures provided by HCFCD.
