Request for Proposals: Selection of Preferred Vendors for Statistical Services

Request for Proposals

Subject:               Selection of Preferred Vendors for Statistical Advisory Services for the Collection and Analysis of Dietary Intake Data

Issued on:           March 17, 2017

Application Submission Deadline:  April 10, 2017

Questions and Answers posted March 31, 2017


FHI Solutions is establishing a Center for Dietary Intake Assessment (hereafter referred to as the “Center”).  The goal of the Center is to help improve the nutritional status of vulnerable populations in low-and middle-income countries (LMICs) by increasing the availability and use of reliable dietary intake data.  The Center’s specific objectives are to:

  • Provide technical assistance to governments, survey implementers, and civil society organizations (CSOs) for collecting, analyzing, and using dietary intake data for evidence-based decision making in low- and middle-income countries (LMICs). (Note: This work is likely to include technical assistance for national quantitative 24-hour dietary recall surveys in LMICs.)
  • Develop an overall composite indicator of diet quality and at least two simple metrics to assess different domains of diet quality for non-pregnant non-lactating women; and
  • Develop a set of metrics to assess and track the cost and affordability of a nutrient-adequate diet by region and at a national level

To carry out the above objectives, the Center anticipates the need to access highly qualified statisticians with the expertise needed to oversee and provide technical assistance related to sampling (including sample size calculation), survey design and/or analysis of quantitative 24-hour dietary recall data.


The purpose of this Request for Proposals is to identify a pool of individuals who are interested and well-qualified to provide statistical services to the Center for tasks related to the collection and analysis of quantitative 24-hour dietary recall data, and identify the contractual mechanism required to engage with each interested individual.  (Note: The Center prefers consultancy agreements; but where necessary, sub-agreements or purchase orders through academic or research institutions will be considered).   The eventual scope of work to be requested is anticipated to include statistical services related to sampling (including sample size calculation), survey design and/or analysis of quantitative 24-hour dietary recall data (including calibration of food frequency data using quantitative 24-hour dietary recall data), statistical review of methodology and/or analytic papers (and co-authorship, where appropriate), and/or statistical review of technical proposals related to the development and validation of indicators.

The Center will review all applications submitted, and may choose to select multiple qualified individuals as “preferred vendors”, to be available to provide statistical advisory services for the Center, as and if requested and available, at a negotiated rate.  Those individuals selected as preferred vendors for the Center will have that designation for one year.  Negotiated rates will be valid for one year following selection.   Initially, the selected individuals will not have any specific defined scope of work. At such time when the Center requires statistical services, a specific scope of work will be negotiated with one of the available statisticians selected through this RFP who has expertise in the specific area of work requested.  It is not guaranteed that a selected preferred vendor will receive a request from the Center to perform work.

The various tasks that the Center anticipates could be included in future scopes of work with qualified individuals, include:

  • Guidance related to sample size determination and survey design for dietary recall surveys
  • Guidance and technical assistance related to the analysis of quantitative 24-hour dietary recall data (including using quantitative 24-hour dietary recall data to calibrate food frequency data)
  • Statistical review of analysis plans, and intermediate and final drafts of technical papers (and co-authorship, as appropriate); and
  • Review of proposals for the development of new metrics related to dietary quality and the cost and affordability of a nutrient adequate diet



This Request for Proposals is to select one or more preferred vendors for a one year period.  Negotiated daily rates are expected to be maintained throughout that year if the Center engages a selected vendor for work.  Selection as a preferred vendor does not establish a contractual relationship between the selected individuals/organization, nor does it have any monetary value.  If or when a selected preferred vendor is approached with a scope of work, the type of contractual mechanism issued (contingent of course on availability and mutual agreement on a final scope of work and budget) will depend on the nature of the vendor.  If it is an individual that is authorized to work independently, a Consultant Agreement will be issued.  If the person’s time is engaged through their employer (i.e., a university or other type of organization), a cost reimbursable Subaward or purchase order will likely be issued based on fixed unit daily rates.
