Dear Prospective Consultants:

The Las Gallinas Valley Sanitary District (District) is seeking Statements of Qualifications (SOQs)

from qualified firms in support of the District’s ongoing Capital Improvement Program. Through

this solicitation, the District intends to establish separate on-call agreements for three distinct

scopes of work: (1) engineering design services, (2) electrical engineering design services, and (3)

construction management and special inspection services. The District anticipates awarding one or

more agreements under each scope. The not-to-exceed amount payable under each agreement for

the contract term is as follows:

• Engineering Design Services: $200,000

• Electrical Engineering Design Services: $100,000

• Construction Management and Special Inspection Services: $300,000

Firms may submit qualifications for one or more scopes of work. A firm pursuing more than one

scope must clearly identify each scope for which it wishes to be considered and address the

qualifications requirements for each scope. Awards for each scope will be made independently.

If you would like your firm to be considered, an electronic copy of your SOQ in PDF format must be

emailed to the attention of Jasmine Diaz at jdiaz@lgvsd.org cc: engineering@lgvsd.org with the

project name and scope(s) of interest as subject heading, no later than 2:00 PM on August 13,
