Sponsored Research Office

The Sponsored Research Office (SRO) is in charge of supporting the University Goal of fostering an applied research environment. It supports researchers in all disciplines by providing information about appropriate sources of external grant and fellowship support for their research and by working with them to prepare grant proposals and budgets. The office is in charge of ensuring that all the proposals submitted on behalf of the institution are in compliance with external and internal regulations. The office personnel also review the proposals before submission for accuracy, completeness, and reasonableness of the budget. The SRO is also responsible for submitting all proposals on behalf of Polytechnic University of Puerto Rico.

Proposal Submission Process

This document will provide investigators and administrators with the information they need to prepare external grant proposals.

  1. The Principal Investigator/Program Director (PI/PD) has the responsibility of writing the narrative and budget of his/her proposal document. However, the SRO will provide advice and help as needed by the PI/PD to prepare a correct budget for the specific agency or sponsor, and the SRO staff will be available to provide one-on-one assistance on a first-come first-served basis.
  2. The Sponsored Research Office requires advanced notification that proposals are under development for submission. Whether the PI/PD requires assistance of the SRO for the preparation of the proposal or not, it is recommended that such a notification be submitted at least three months before the proposal submission deadline. In any case, the SRO must be notified in writing at least one (1) month before the proposal submission deadline. The notification must include:
    1. The name of the program and agency/sponsor
    2. The request for proposal (RFP) or equivalent document 
    3. The deadline for submission of the proposal
    4. Any other requirements (such as cost-sharing, compliance, subcontracts, etc.).
  3. In order to submit a proposal, the SRO requires that a complete and final version of the proposal is submitted to the office at least six (6) working days prior to the submission deadline. Proposals involving subcontracts or other special interactions with other institutions will require more time than this six-day minimum to be determined on a case by case basis.
  4. Any proposal must be accompanied by a letter of support (LOS) from the head of the respective department. If the proposal involves graduate students or graduate programs it must also have a letter of support from the Graduate School Dean. If the proposal affects more than one department, a LOS from corresponding school Dean is required. If the proposal affects more than one school, a LOS from the Vice-President of Academic Affairs is required. The SRO will be in charge of requesting letters of support from the President, if required, once all the previously mentioned letters are submitted to the SRO.
  5. A complete proposal must include at least:
    1. Project Summary or Abstract
    2. Project Narrative
    3. Budget
    4. Budget Justification
    5. Letters of support as specified in item 4.
    6. Any mandatory document specified in the call for proposal.
  6. If a program allows only one submission per institution, the first person notifying in writing the SRO of his/her intentions to submit a proposal to that program will have the right to submit.
  7. The PI/PD who does not to notify the SRO about his/her intention to submit a proposal in a timely manner will face the possibility of an institutional denial to submit such a proposal.
  8. Even if the narrative portion is under development, the budget should be provided to the SRO as early as possible in the process for review.  Having this in advance of the deadline enables our staff to review the budget according to the agency requirements and university policies. This gives time to the PI/PD to make corrections to the budget even before the narrative is finished.

The SRO has established these requirements in order to better serve the institutional and departmental goals as well as standardize the procedure for all our researchers and other individuals pursing external funding, and to be able to contribute to an increasingly demanding research proposal agenda.

Intellectual Property Procedures

Polytechnic University of Puerto Rico is supporting and encouraging the submission of patent applications from faculty and staff, according to the current Intellectual Property Policy approved on February 24th, 2010. This effort is done to incentivize the production of intellectual property that benefits both, the IP originators and the university. The following steps will be followed to submit an application for patent:

  1. The applicant will fill an Intellectual Property Disclosure Form and submit it to the Sponsored Research Office (SRO).
  2. The SRO will hire a firm to conduct a Patent Search, and will determine if the Intellectual Property (IP) is considered a University Assisted or Assigned Effort or an Individual Effort. Based on the outcomes of the patent search, the SRO will submit a recommendation to the Intellectual Property Committee (IPC).
  3. The IPC decides if the University will pursue a patent for the submitted IP.
  4. If the University IPC decides to pursue the patent,

    1. The applicant will fill out an Originator Assignment Document
    2. The SRO will hire a firm to conduct a patent application. The applicant will meet with the firm personnel for any further explanation necessary in the generation of the claims for the patent application.
  5. Once the patent pending status is documented, the University may initiates negotiations for the commercialization of the Intellectual Property.
  6. If the University decides not to pursue the patent, the applicant may request a copy of the IP decision to pursue the patent of the IP on his/her own.

Interactive Computer Program for the Analysis of Non-prismatic


Reinforced Concrete Bridge Girders

Sponsor and Date

Puerto Rico Highway and Transportation Authority, Department of Transportation and Public Works, 1996-1997.

Faculty and Students

  • PI - Gustavo E. Pacheco-Crosetti, PhD, PE
  • CoPI - Eduardo Veras-Jorge, PhD, PE
  • Student - Eduardo Miranda, undergraduate


Summary and Outcomes

Highly-interactive, graphically-oriented, special purpose Finite Element Analysis program, within MS-Windows environment as the Graphical User Interface (GUI). The system has been developed for PC computers, and Visual Basic has been selected as the programming language, due to its versatility and the advantages of its toolbox to develop applications following the MS-Windows standards.

The application is called NPB program, which can be defined as an interactive computer program for the analysis of Non-Prismatic Beams (or similar structures) by means of plane stress Finite Element Analysis (FEA). The program performs plane stress analysis, using four nodes isoparametric elements (Q4), considering static loads, linear elastic material behavior, and the small displacements theory. It is specifically oriented to non-prismatic beam type models (defined by two vertical boundaries at the most left and the most right limits).

A model analysis may be divided into three implementation phases: a) Pre-processing Stage, where the model data is defined, b) Processing Stage, where the automatic meshing of the model, and the finite element analysis are performed, and c) Post- Processing Stage, where results are consulted. Regarding these phases, the program permits the user, among other features, to:

Pre-Processing Stage:

  • Define the solid modeling using lines, parabolas and circle arcs
  • Assign different support conditions, including elastic supports
  • Assign different loads conditions (concentrated, distributed, self weight) I.4. Verify/modify model data presented in tabular form
  • Display the identification of solid modeling elements (KeyPoints, Curves) I.6.Perform Zooming options
  • Activate/deactivate many visibility options
  • Save the solid model (or FEA model) as a bitmap file
  • Copy the solid model (or FEA model) as a bitmap to the Clipboard

Processing Stage:

Define the parameters to control the number of divisions for the meshing II.2Perform the automatic meshing of the solid modeling with quadrilateral elements Perform an static linear elastic analysis of the model, using plane stress elements

Post-Processing Stage:

Review the results file (nodal displacements, element strains and stresses) Future developments will include the graphical post-processing of the results (i.e. deflected shape, stress contours, etc.)

1.2.3. Summary and Outcomes

Highly-interactive, graphically-oriented, special purpose Finite Element Analysis program, within MS-Windows environment as the Graphical User Interface (GUI). The system has been developed for PC computers, and Visual Basic has been selected as the programming language, due to its versatility and the advantages of its toolbox to develop applications following the MS-Windows standards.

The application is called Visual Slab program, which can be defined as an interactive computer program for the analysis of slabs on grade models, subjected to moving truck loads, and falling weights. The program speed up model generation, performs the automatic meshing (Finite Element Model) of the solid model, and performs static and dynamic (time history) analysis using isoparametric four nodes plate elements, dowels connecting plates, considering non-linear soil behavior, and the small displacements theory.

A model analysis may be divided into three implementation phases: a) Pre-processing Stage, where the model data is defined, b) Processing Stage, where the automatic meshing of the model, and the finite element analysis are performed, and c) Post- Processing Stage, where results are consulted. Figure 5 schematizes this processes, and Figures 6 to 8 show examples of the program capabilities.

Summary and Outcomes

The Professional Development Program In Transportation Infrastructure Inspection (PDP-TII) is a cooperative agreement between Alternate Concepts Inc (ACI) and Polytechnic University of Puerto Rico (PUPR).

The Program has three principal objectives:

  • Stimulate the development of engineering students in the area of Transportation Infrastructure Inspection and Maintenance.
  • Perform an inspection and maintenance assessment program of the San Juan Railway System (TU) structures and drainage infrastructure.
  • Propose possible improvements to the inspection, condition evaluation, and maintenance assessment processes of transportation facilities.

The program consists of five stages:

Formative Stage

Students are trained trough seminars and workshops in several topics

  • Fundamentals of Inspection and Monitoring.
  • Structural Failures, Damages, and Deterioration.
  • Damage and Condition and Rating.
  • Types of and Damages in:
    • RC Structures.
    • Steel Structures.
    • Retaining Walls.
    • Earth Slopes.
    • Drainage Infrastructure.
    • Tunnel Facilities.
  • Visual Inspection Procedures and Equipment.
  • Safety.
  • TU Infrastructure.
  • Condition Assessment and Rating.
  • Documentation and Reporting of Findings.


Research and Development Stage

Students have to perform extensive literature review on visual inspection procedures and condition assessment rating around the world, and propose improvements in all the stages of the process:

  • Inspection procedures and equipment.
  • Inspection forms.
  • Infrastructure identification and location.
  • Findings documentations.
  • Assessment of the field conditions found trough objective and quantitative rating scales.
  • Required level of intervention according to obtained rating (i.e. routine maintenance, repair, replacement, among others),to support the establishment of priorities in the maintenance process.


Inspection Stage

The concepts learned in the previous stage are applied to different components of the TU infrastructure.

Example of Damage Found in Sidewalk Parapet


Evaluation Stage

The findings of the inspection are evaluated, and a condition rating is assigned (that helps decide the type of maintenance process required to assure adequate safety and operational conditions).

Reporting Stage

A detailed report of the findings and the assigned condition is developed. An evaluation of possible causes to the discovered findings, and recommended intervention are also developed.
