Description of Professional Services
DuBois & King was recently selected for Mechanical/Electrical Indefinite Delivery Contract to support mechanical and electrical projects involving repair and renovation of historically significant buildings, food service areas, and laboratory, science, and technology buildings at the University of New Hampshire. Previous contracts from 1995 to 1999, involved assessment of needs, planning, programming, evaluation of alternatives, cost estimating, preparation of reports of findings, preliminary and final design, and bid documents. Work orders have included:
Dining Service Energy Audits
Walk through energy audits of four buildings operated and managed by UNH Dining Services. Serviced include building inspections, staff interviews, and review of blueprints; preparation of final written report addressing all building systems affecting energy consumption including building envelope, HVAC systems, lighting, controls, electrical systems, cooking, dishwashing and refrigeration equipment, and water conservation opportunities. Investigated opportunities for improving energy efficiency via operations and maintenance procedures. Final report included energy efficiency recommendations for proposed renovations and modifications scheduled for summer break.
Arts Wing Ventilation Upgrade, Paul Creative Arts Center
Design of ventilation systems, based on previously completed ventilation study, to control fumes generated by art processes and temperature and humidity control systems for art storage spaces. Includes preliminary and final design documents, bidding assistance, construction phase services, and final inspection. New systems service approximately 26,100 square feet of facility.
Ventilation Study, Paul Creative Arts Center
Performed site investigations to verify existing conditions in five studios, evaluate ventilation equipment capacities and existing distribution, verify code requirements, identify ventilation problems, recommend measures to resolve air quality issues, determine make-up air requirements, verify heating capacity for make-up air, and develop cost estimates for recommendations.
Johnson Theater Renovations, Paul Creative Arts Center
Evaluation of various rehabilitation alternatives and design of renovations for Johnson Theater in Paul Creative Arts Center. Included replacement of stage floor using removable panels, replacement of stage rigging and counterweight system, adjustments to on?stage climate control, eliminating noise in auditorium mechanical system, and replacement of smoke hatches.
Kendall Hall HVAC/Plumbing Evaluation
Performed evaluation of HVAC and plumbing systems in 5-story building comprised of laboratory, library, and animal/veterinary research space. Included site visit to verify existing conditions; evaluation of HVAC systems (including fume hoods) and recommendations to improve system efficiency and performance; evaluation of cooling requirements for existing electron microscope and determine whether installed system is adequate, over or undersized; investigation of alternatives for increased personnel safety on roof of building (safety railing); evaluation of building envelope and recommendations on how to make building more efficient; payback analysis of recommendations; and determination of estimated costs of proposed changes.
Farm Services Building Ventilation
Ventilation improvements to single-story building due to welding and other smoke producing processes. Conducted site visit to verify existing conditions, ventilation equipment capacities; current distribution and code requirements based on existing occupancy. Design of ventilation system improvements and heating system modifications to support improved facility ventilation. Prepared plans and specifications for bidding, construction cost estimates, and attendance at review meetings during design process.
Hewitt Hall HVAC Evaluation and Modification
Evaluation of existing HVAC system in basement of Hewitt Hall to determine compatibility with future renovation of unfinished space into classrooms. Services included review of original drawings of existing building HVAC systems; site visit to confirm drawing information and existing conditions; determined code requirements for HVAC systems as related to planned future occupancy; calculations to determine extent of needed HVAC system modifications; generation of sketches and report suitable for development of bid documents; and generation of material specifications for mechanical and electrical equipment required for recommended modifications.
Field House Exercise Physiology Laboratory HVAC Design
HVAC engineering services in support of development of new exercise physiology classroom in the Field House. Site visit to gather information on existing mechanical systems in the Field House and document field conditions; developed baseline drawings; engineering evaluation of existing HVAC systems to determine feasibility for modified use in new exercise physiology laboratory; design of HVAC system to serve new laboratory; and development of drawings and specifications suitable for bidding purposes.
High Pressure Steam Distribution Modifications
Mechanical design for modifications to high-pressure steam and condensate return lines. Campus steam distribution consists of 5-inch diameter, 80-psig steam mains located in utility tunnels along Main Street and Library Way. Project objective was to increase capacity of steam distribution system by cross connecting steam and condensate mains. Site visit to verify existing conditions, take measurements, and collect site and utility plans; review load data and previous study of steam/condensate network to determine optimum steam pipe size and location; review existing utility plans; develop site plan of area using AutoCAD; design of steam line cross connect including expansion loops, hangers, etc.; evaluate flow conditions in steam line based upon high points, low points, etc.; analysis of necessity of condensate removal system; development of tunnel penetration and pipe connection details; selection of equipment; development of specifications, construction documents, and construction cost estimate; and issuance of construction documents for bid.
Water Treatment Plant Sludge Disposal Study
Conducted feasibility-level screening analysis to identify and evaluate long-term sludge management alternatives for water treatment facility to discontinue use of existing leaching pit.
- Phase I - Collection of Background Information and Identification of AlternativesReview of existing information about treatment process, chemical usage, sludge lagoons, and leaching pit to establish current sludge handling practices and volumes; contact and coordination with appropriate state and local agencies to discuss regulatory requirements of alternatives; finalization of sludge management/disposal alternatives to be evaluated included discharge of solids in a liquid (suspended) state to Durham WWTF or dewatering and landfilling at a certified solid waste disposal facility; review of advantages/disadvantages of using alternative coagulant chemicals; review of results with UNH and Town representatives.
- Phase II - Preliminary Screening of AlternativesSummarization of results of information gathering phase, identifying non-economic advantages/disadvantages of each alternative; preparation of summary including advantages/disadvantages, restrictions, and environmental ramifications of each alternative for review by UNH/Town representatives. Recommendations of two alternatives for further economic analysis; and meetings with UNH/Town officials to discuss the report and obtain consensus.
- Phase III - Economic Analysis and Preparation of Final ReportIdentified system requirements and primary components for each option; schematic diagrams showing primary process components and configurations; feasibility-level cost estimates of capital components of each system; coordination with water/wastewater facility staff to prepare estimates of operating costs associated with current and alternative sludge management practices; preparation of a present-worth analysis, comparing costs of each alternative over 20-year planning period; summarizing results in report with final recommendations.
