8 Project Description6. Cost Estimate The estimate was developed by the Project Manager and adjusted and validated by the designers’ estimator. The project estimate at bid and area analysis is as follows: Main Hospital and supporting areas (356,000 S.F.) = $ 74,000,000 Unit Cost $ 210/S.F. Housing and Dormitories plus supporting areas (197,000 S.F.) = $ 18,000,000. Unit Cost = $ 93/S.F.Total Estimated Costs $ 93,000,000

10 GeneralValue engineering is a creative, organized approach , whose objective is to optimize the life cycle cost and/or performance of a facility.A multidisciplinary team was formed.The objectives of each team member were to:analyze the project,find high-cost areas,recommend alternatives,estimate initial and life cycle costs whenever significant for the original system and for each proposed alternative, andassure that proposed recommendations did not sacrifice essential functions and timely completion of the project.

24 Judgment PhaseVE team judged and ranked the ideas generated from the creative phase.Evaluating Factors:State-of-the-art of the idea,Cost to develop,Probability of implementation,Time necessary to implement,Magnitude of idea’s potential benefit, andAesthetics.Ideas were ranked from 1 to 10.Ideas with a ranking of 8 or more were developed further.

27 Development PhaseSome 127 ideas were generated during the initial review phase, from which 56 ideas were developed.Some 22 design suggestions representing VE team design review type comments were generatedThese proposals represent potential initial savings of over $16,000,000 and additional follow-on potential savings in operation, maintenance, and increased revenue of about $265,000/year.Suggested recommendations of potential deferred construction costs for supporting and medical equipment are included amounting to some $5,000,000.
30 A7 Original Design Proposed Design The clinical labs and hemodialysis department are located between axis 10, 15 and A, F. they are divided into separate areas for blood donation, clinical lab and for hemodilysis.Proposed DesignConsider rearrangement of the clinical labs and blood donation as per Sketch No. A-7 the change allows for an improved separation between the donation area and clinical labs, and accessibility of outpatients to donation area. In addition, switching the donation area and hemodialysis area will allow an increase of 3 additional beds for hemodialysis patient. Note: See ME 6 for overall savings generated.Discussion, Advantages and DisadvantagesThe rearranged layout improves the flow of outpatients to the labs and blood donator to the donation area, keeping the required privacy of the clinical labs. It will allow the addition of hemodialysis beds that will increase the revenue of the hospital. Also, the present design does not accommodate pediatric patients. Additional beds will be designated for this purpose.
33 A8 Original Design Proposed Design Calls for 7 in. exterior precast concrete wall panels for both hospital and housing.Proposed DesignUse 5 in. precast wall panels for hospital only.Use CMU, plaster and texture paint for housing units.Discussion, Advantages and DisadvantagesThe VE team discussed this issue with a local manufacturer who indicated that a 5 in. panel would be sufficient.This change will give a considerable weight and will save money.Maintenance cost should be slightly higher for the housings exteriors and for the thinner precast wall panels. It should not exceed $ 3000 / yr.
41 ME 6 Original Design Proposed Design Present design call for 4 beds in hemodialysis.Proposed DesignRevise design to add 3 additional beds.Discussion, Advantages and DisadvantagesThis area is in demand. Hemodialysis is a needed service with long lists at existing hospitals. The local market should be more than able to supply the need for the additional beds.

46 SummaryGeneral The team suggests that the Owner considers two options to defer initial cost outlays:Delete nurses’ house and rent space. A rough cash flow analysis indicates Owner will be some $200,000 /yr ahead using an equivalent cash flow analysis avoiding a $3,500,000 capital expenditure.Consider design build, lease-back for 20 years. By doing this Owner will defer some $15,000,000 in capital outlay and own the facilities after 20 years. He incurs some additional annual leasing costs that would be less than amortizing his capital investment over 20 years.Note: The above savings are not additive.
47 Summary- ContinuedArchitectural - 16 Items totaling approximately $3,500,000Structural -2 Items totaling approximately $130,000Mechanical - 14 Items totaling about $1,000,000 in initial and $110,000/yr. in annual savingsElectrical - 11 items totaling approximately $3,800,000 in initial savings and $100,000/yr. in annual costsMedical Equipment - 9 Items totaling approximately $7,500,000 in initial costs plus $650,000/yr. in additional income
50 Summary- ContinuedEventually, 35 proposals were implemented. Initial cost savings between $10,000,000 and $12,000,000 should result and annual follow-on costs up to $1,000,000/yrThat’s about 11% to 13% savings in initial costs.
