SUMMARY OF PROCESS

In March of 2016 the Vashon Parks District retained ORB Architects, an architectural firm specializing in the design and evaluation of aquatic facilities, to perform an evaluation of the existing outdoor pool in order to document the condition and recommendations as part of this Engineering Service Report. ORB has brought together a team of professionals in order to evaluate the existing pool. This team includes Enginuity Systems for the plumbing and mechanical (including the pool mechanical systems), and Cross Engineers for the electrical. Each team partner has extensive experience and specializations related to the design and evaluation of aquatic type facilities.

The purpose of the assessment is to gain a full picture of the physical and operational condition of the existing pool in order to plan future maintenance and upgrade priorities and costs. The resulting goal is to provide details on what we considered to be short-term and long-term needs for the pool facility for planning purposes.

As part of our scope, we completed a checklist of all building and Washington Administrative Code (WAC) requirements as well as noting the visible condition of building and equipment. The mechanical engineer reviewed the pool equipment, documented the piping systems and worked thru his own checklist. The electrical engineer observed the electrical panels and noted the non-working condition of some of the exterior lights and other elements The Vashon Parks District was able to locate some Record Drawings of the Pool and Bathhouse for use in evaluating the facility as well.

This is the Engineering Service Report which represents a complete picture of the existing conditions at the Vashon Pool. It also outlines our recommendations for repair and maintenance needs. It is our understanding that this report will be part of the public record used to plan for the facilities future.

GENERAL

Our team visited the facility on March 21st, 2016 to perform a visual assessment.

We first met with Elaine Ott, Vashon Parks Executive Director, Scott Bonney, the Vashon Parks Aquatics Director and other staff to review the scope, existing information and gain access to the site. The objective of this assessment is to help with planning and budgetting.

Scott was very helpful in giving us an understanding of the existing systems and any known issues we should be aware of. After this meeting we performed our on-site inspections.

The team that coordinated the information in this report includes:

Elaine Ott - Vashon Parks District, Executive Director Scott Bonney - Vashon Parks District, Aquatics Director Geoff Anderson - ORB Architects Jesse Barksdale – Enginuity Systems (Pool Mechanical) Scott Kelly - Cross Engnieers (Electrical Engineering)

BACKGROUND

The Vashon Pool was constructed around 1975, during the Forward Thrust era that included dozens of pool facilities in King County. The total facility is nearly 17,500 square feet, with 3,823 sf for the Natatorium. Other functions in the building include a gymnasium, men's and women's dressing rooms, staff areas, offices, and various support spaces.

The Swimming Pool is a 6 lane lap pool, with a 1-meter diving board. It's approximately 3,270 square feet with overall dimensions of 75' by 44' and holds 165,000 gallons.

The pool is a positive feature within in the Vashon Island community that serves many people, including a swim team and other aquatic sports. There are two (2) other pools on the island associated with private clubs. The Vashon Parks District is pro-actively looking forward and planning for how they will be able to preserve, and possibly improve this community asset.

As noted above, the Vashon Pool is one of approximately 23 Forward Thrust swimming pools. Of those 23 pools, only 3 have been closed down. Of those 3, 2 have essentially been replaced by new public pools, and the 3rd was overhauled and has reopened under private ownership. Between 2002 and 2008, King County turned over the ownership and operations of all the Forward Thrust pools to the local jurisdiction where that pool resided. In nearly every case, the new owner is a city, municipal park district, or a school. Most are operated directly by the owner jurisdiction. However, several are operated by non-profit companies under contract with the jurisdiction. When the pools were turned over, the majority of them also underwent some level of renovation improvement to extend the useful life of the facility. A list and summary of the Forward Thrust Pools is included in the Appendix for comparison.

ASSESSMENT

Based on the initial investigations, we can tell that the tank has been well loved, but that 30 years of use means that it is showing significant signs of wear. Therefore, it is appropriate to perform this assessment to document and prioritize parts of the facility that are near the end of their useful life and consider ways the facility can become more compliant with current codes.

Included with this Vashon Pool Assessment Report is an Area of Magnitude cost estimate breakdown of the items that have been identified by our team. The costs are identified as either short-term recommendations or long-term recommendations. The goal is to develop a plan that allows the Vashon parks District to plan for and strategies budgets and construction that will allow for the continued operation and use of the community pool.

A|4 recommendations

RECOMMENDATIONS

Our goal is to identify and recommend a range of maintenance, replacement, and/or repair scope items for the Vashon Pool based on our observations of the facility and research of available documentation.

In addition, we are looking to provide a “road map” for the Vashon Parks to anticipate and plan for maintenance and operational upgrades over the next several years. The goal is to assign appropriate scopes of work that can be budgeted and sequenced logically.

IMMEDIATE NEEDS

Immediate needs include critical life-safety, and accessibility scope items. Several of the items listed under immediate needs are related to code provisions which are not acceptable as "grand-fathered" conditions. In particular, a pools compliance with the Virginia Graeme Baker Act (VGB) is mandatory, as well as providing access in to the pool, per the Americans with Disabilities Act (ADA).

ADA ACCESSIBILITY

• Assure that a proper compliant ADA Lift is available at the pool (Owner Item)

• Increase the accessibility at the Changing rooms to the greatest extent possible within the existing limitations of the building.

MECHANICAL

• Replace the main drains and branch piping at the drains. Configure piping with equal-length branches, and provide drain sumps and covers that comply with APSP-16 requirements for anti-entrapment.

(Note: The 2009 permit application has expired and will need to be resubmitted)

• Rewire the boiler shutoff switch to deactivate the boiler as well as the (2) gas water heaters

A|5

SHORT-TERM RECOMMENDATIONS

Short-term recommendations are generally those additional items that relate to life, safety and welfare concerns. Some of these are inevitable with a pool of this age and others are a result code compliance upgrades changes over the years.

Short-term recommendations should be completed within the next one (1) to two (2) years.

The following are the short-term or current actions we recommend. See the attached spreadsheet for item headings along with anticipated construction costs.

ARCHITECTURAL

WAC 246-260-031 & 041 (State swimming pool code)

• Repair the pool decks and deck drainage

• Refurbish the pool shell and provide safety upgrades

MECHANICAL

• Replace the mechanical systems in the pool mechanical room, including the following:

• New pool circulation pump & piping

• Provide variable frequency drive (VFD) for new pump

• New flowmeter

• New valves

• Add float valve to main drain pipe inside the surge pit

• Provide new pool control panel and interlock system to properly connect & control all pool system pumps

• New sump pump system

• Add overflow drain from surge pit to sump pit

• Provide new NSF-approved vacuum DE filter system, or change to pressure sand filters. Filter will be sized to match flow rate

• Connect new circulation systems to solar pool heating system

• Stainless steel or other corrosion-resistant materials used for pipe supports

• Configure the pool heating piping so that the solar heating and boiler heating are not in series

ELECTRICAL

• Restore the exterior lighting, including the lighting control and power panel for all lighting

• Replace \ equipment in the Chemical Storage Room with equipment rated for hazardous locations.

A|6

LONG-TERM RECOMMENDATIONS

Long-term recommendations are those items that the Vashon Parks District should be planning and budgeting for soon. In our opinion, they will be required to be done for the long-term viability of the pool facility within the next three (3) to five (5) years. Many of these recommendations are significant cost items that the Vashon Pool would need to set priority levels and budgets for.

See the attached spreadsheet for long-term item descriptions along with anticipated construction costs.

OWNER ITEMS

Owner items are deficiencies that have been documented as part of our site observations in this report, but we have been informed that they will be completed by the Vashon Parks District. For these items the owner has either already been working to resolve the issue, or has agreed to do the corrections and/or repairs in-house.

This includes necessary repairs to the Chemical Storage Room that are planned for completion prior to the 2016 swim season, and the procurement of an ADA lift.

MAJOR RENOVATION CONSIDERATIONS

Since the Vashon Pool was built 40 years ago, codes and technologies have changed. As a result, there are deficiencies at the facility that are not practical to correct, including some ADA compliance issues. In most cases, there are provisions for allowing facilities to continue to operate with such "grand-fathered" conditions, so long as and upgrades are restricted to minor renovations and maintenance.

A major renovation would result in the facility needing to be upgraded completely to current codes throughout. Generally a project is considered a major renovation when costs exceed 50% of the facility replacement value; however this is determined by the local jurisdiction based on a review of the actual scope involved.

To give you an idea of the Vashon Pool estimated replacement value, we have provided an Area of Magnitude Construction Cost Estimate.

A|7 summary of costs

AREA OF MAGNITUDE COST ESTIMATE

The summary of costs on the following page outline a strategy for planning the upgrades and repairs at the Vashon Pool Facility. A more detailed breakdown of the costs are included in Section E Cost Estimate.

Note that the costs we are estimating the full costs that you would have when the work is bid as part of a General Contractors work, and includes his markups as well as the sub-contractors. These are industry standard costs for a publicly funding job, including prevailing wages, bonds, insurance and sales tax.

Additionally, we have included a 20% contingency to cover the fact that this is only conceptual at this time, as well as a 10% “island” location factor. See the summary of markups included in Section E.

For a single scope item, such as the boiler replacement, you may be able to get a local contractor to do the work without subcontractors and the costs would drop accordingly. However, for the purposes of a feasibility study such as this, we feel it is our responsibility to illustrate a realistic cost that assumes a General Contractor with sub-contractors from Seattle or Tacoma would be bidding the job.

In the summary on the following page you will notice that there are a couple of items that have alternate approaches. These are highlighted and only the cost of one of them is included in the total. Since all scope items are listed as individual, stand-alone tasks, it should also be pointed out that some of the costs may overlap. For example, the deck drain is a stand-alone project under its own heading that assumes the existing decks doesn't get replaced. However, the deck replacement cost, which is also a stand-alone cost, also included new deck drains, since you could not complete that task without the drains.

SWIMMING POOL ANALYSIS

WAC 246-260-031 & 041 (State swimming pool code) The Vashon Parks District Pool is a Summer use, outdoor pool. During the operating season it is open from 6 am until 7:30 pm.

The notes below are generated from our checklist which uses WAC 246-260-031 as a basis. See the Appendix at the end of this report. Additional items are described in the Mechanical and Electrical assessments where the scope is in their area of expertise.

• The Pool Deck is in poor condition with many cracks and damaged areas. The original deck surface is an exposed aggregate that has worn to a relatively slippery surface.

• The deck drainage consists of a thin linear type drain embedded in the deck that appears to be heavily clogged.

There were areas observed with ponding right over the drain and grass and weeds grew through the drain holes throughout the length of the drain.

• Most of the Pool Valves are corroded. See the mechanical engineers assessment.

• According to the Record Drawings, the Main Drains are plumbed in series and do not comply with current code. See the mechanical engineers assessment

• The Removable Stairs should be refurbished to restore the contrasting edge color as a minimum.

• The existing Chemical Storage room is heavily corroded, with the exhaust fan rendered inoperable.

It has been condemned by Fire Marshal. The Vashon Parks District has contracted to have this room restored by others prior to the opening of the 2016 swim season

• Just north of the pool are 3 settling tanks for the backwash. At least one of the tank lids is heavily damaged and open to the air, allowing additional debris to enter the tank. This should be repaired.

• Several of the self-closing faucet valves at the sinks only stayed on for a few seconds.

• The exterior pole-mounted light fi xtures are mostly not working. The hours of operation are during daylight times, that should meet the minimum lighting needs, but the lighting would supplement that, or allow for extended hours. See the electrical engineers assessment.

• The diving profi le for a 1-meter board is not fully compliant with the FINA facility rules, 200-2001 per WAC requirements. See the section diagram on page B|5.

• Depth Markings should be placed at a maximum intervals of two feet or less per WAC 246-260- 041(8)(d). The existing Pool depth markings skip from 5'-0" to 10'-6"

• The existing Pool shell has a plaster fi nish and tile markings. Much of the tile at the deck level is damaged and has several areas of non-matching patches. It is assumed that due to the age of the pool, it is in need of refi nishing the plaster and have extensive tile repairs.

B|3B|3

ADA ACCESSIBILITY

The notes below are relative to International Building Codes, ICC/ANSI A117.1 and Federal Guidelines for Accessible Design.

• The staff indicated that a hand cranked type ad lift is available at the pool, but it was not observed during our visit. This type of lift is no longer acceptable for meeting the Federal ADA requirements, that call for the lift to be fixed in place during pool operations and self-operable. There are some removable steps that were observed to satisfy the second required means of access. (See notes under Swimming Pool Analysis)

• The Guard Station is not accessible. Is is assumed that only able bodied personnel will serve as lifeguards accessing this area.

The Dressing Rooms were built in 1972-73, before the ADA. There are several ADA deficiencies in the Changing Rooms as follows:

• The toilet seats were measured at 19-1/2" which exceeds the 19" maximum. Access to the women's accessible toilet stall is too narrow to be compliant.

• The clearances at doors do not comply with ADA for operation. It is assumed that during the hours of operation the doors into and out of the dressing rooms are propped open to allow access, and only closed for securing the building. Therefore this would be a factor at those doors.

• There is not an ADA compliant bench in the Changing Rooms. A bench meeting the size requirements with a back should be provided.

• A shower area is designated for accessibility in each changing room, however they do not comply with ADA guidelines.

• The one drinking fountain located in the lobby area is not fully accessible. It is too shallow.

GENERAL ARCHITECTURAL

The notes below are related to general observations of items not covered in the categories above.

• The condition of the Bathhouse structure, including most of the metal doors, appears to be good.

• There is an existing hot water solar system on the roof, that works well. The condition of the roof itself appears to be in good shape. We were able to observe the attic space in one area and all the framing appeared to be dry and in good condition.

RECOMMENDATIONS

Immediate Needs Short-Term Recommendations:

WAC Items:

1. The original pool deck area (exposed aggregate) is in disrepair and presents an unsafe condition. It should be replaced with a broom finished surface. The added deck area to the south appears to be in good shape and can remain.

2. The replacement of the deck area should include a complete replacement of the lineal drain around the pool that provides proper drainage and is easily maintainable.

3. The existing Removable stairs should be refurbished to restore the contrasting edges.

4. It is our understanding that the Vashon Parks District is already procuring a contractor to do repairs at the existing Chemical Storage Room. We have included this in our report to track it as part of the project. Proper ventilation should be restored and all equipment should be replaced.

See the mechanical and electrical narratives for additional information

5a. Reconfigure the pool profile at the deep end wall to comply with FINA diving requirements 5b. Replace the existing diving board with a 1/2-meter diving board that would be safer and likely to comply under the CNCA guidelines per WAC.

6. At the time of replacing the decks, and refinishing the pool, provide all new depth markings.

We recommend that the replacement not include the deck tiles were practical to avoid long-term maintenance issues related to the freeze/thaw cycles at an outdoor pool.

7. Refinish the plaster liner, and repair all the tile in-kind.

8. Upgrade the existing gutter system with a flush gutter. This option could be used to increase the depth at the shallow end by about 6" as well, which would help with competitive swimming.

ADA Items:

1. Vashon Parks District has provided information on an alternate lift that will be made available and installed at this pool per code. See the Appendix for the lift information provided.

2. Add an ADA compliant bench in each Changing Room

3. Build a third wall at the ADA shower area to provide a proper ADA layout

4. Replace the drinking fountain in the lobby area.

Long-Term Recommendations:

WAC Items:

9. Replace the lids at the backwash settling tanks.

ADA Items:

5. Due to the prohibitive nature of the existing building, it would be impractical to reconfigure the toilet stalls in order to be compliant. Recommend noting this as a variance. The toilets themselves are very close to being compliant, and should be corrected during any future repairs or renovations.

Maintenance Items (WAC related):

10. Check all the faucet valves and repair or replace as necessary.

C. MECHANICAL ASSESSMENT

GENERAL MECHANICAL

MECHANICAL OBSERVATIONS

MECHANICAL RECOMMENDATIONS

C|1 mechanical assessment

GENERAL MECHANICAL

We visited the Vashon Pool facility on March 21, 2016, along with ORB Architects and Cross Engineers in order to perform site investigation of the existing pool and supporting facilities.

The original facility was built around 1975/76, and some changes/updates have been performed over the years. Generally speaking the pool mechanical systems are showing signs of aging and in need of replacement in order to restore proper function, improve efficiency, or bring systems up to current applicable codes.

This report is based on visual observation of the existing facilities as well as review of the existing facility drawings.

The pool is approximately 165,000 gallons in volume. Current codes require a 6-hour turnover rate, which in this case would be 460 gpm. The existing circulation system is designed for a 540 gpm flow rate, and staff has reported flow rates as high as 650-700 gpm. It is not known if the current flowmeter is correctly calibrated, and generating proper flow readings.

The pool is served by a vacuum DE filtration system. Heating is provided via a gas-fired boiler as well as a solar pool heating system. Pool chemistry is maintained by a BECS System 2 automated controller and liquid chlorine and acid systems.

The HVAC systems serving the restrooms, mechanical rooms, and offices were not active the day of the site visit. As a result the functionality of these systems is not included in the scope of this report. The ducts and equipment located in the attic space appeared to be generally in good condition.

C|2

MECHANICAL OBSERVATIONS

• There are (2) hose bibbs serving the pool deck, but none at the west end of the pool.

• No float valve was observed on main drain line from pool. As a result there does not appear to be any way to set the system to maintain the minimum 60% of the flow rate over the gutters.

• Existing drawings indicate that the main drains are piped in series. This does not comply with WAC

246-260-031-8-e.

• The pool was covered at the time of the site visit so the drain covers and sumps could not be observed. It is unknown if the drain covers and sumps comply with the APSP-16 suction fitting standard.

• Chemical storage does not comply with WAC or NFPA requirements. Large quantities of chemicals were observed in the main mechanical room, blocking access through the room. Incompatible chemicals (chlorine and acid) were stored in the same space. This is a fire code violation as well as an extreme health hazard.

• The existing chemical room has been condemned by the local fire officials and is in need of complete refurbishing – including ventilation, electrical components, and chemical feed systems.

• No airgap or backflow preventer was observed on the pool fill/makeup water piping. The discharge from the fill/makeup line terminates directly in the surge pit, with the pipe opening below the water level.

• The pipe supports in the mechanical room are in poor condition. Some are cutting into the piping & fittings.

• The existing vacuum DE filter system appears to be in good condition, but appears to be undersized for the design flow rate or flow rates that have been reported by staff. Typical application rate for vacuum DE filters is approximately 1.5 gpm/ft2, the current configuration has an application rate of between 3.46-4.40 gpm/ft2.

• It is unknown if the filter system is NSF approved.

• No overflow outlet was observed at the surge pit.

• The drain valve from the filter pit to the sump pit is leaking, and is missing the valve handle extension.

• Staff reported that the Griswold valve is non-functional.

• The boiler shutoff switch only deactivates the boiler, and not the (2) gas-fired waters in the same room. This is a violation of the Washington State Boiler Regulations.

• Staff reported that the compression tank at the boiler is non-functional, and has to be drained daily.

• Staff reports that the boiler short-cycles. This may be due to the solar heating system being piped in series with the boiler.

• The restrooms did not appear to have adequate floor drainage.

• The pool systems control panel in the mechanical room is in extremely poor condition.

C|3

MECHANICAL RECOMMENDATIONS

1. Replace the main drains and branch piping at the drains. Configure piping with equal-length branches, and provide drain sumps and covers that comply with APSP-16 requirements for anti-entrapment.

Note: The 2009 Permit Application for VGB compliance was never approved or inspected. A new application and documentation will be required, including documenting the existing conditions and/or any modifications made.

2. Replace the mechanical systems in the pool mechanical room.

a. New pool circulation pump & piping.

b. Provide variable frequency drive (VFD) for new pump. Control based on flowmeter reading to maintain flow rates.

c. New flowmeter.

d. New valves.

e. Add float valve to main drain pipe inside the surge pit.

f. Provide new pool control panel and interlock system to properly connect & control all pool system pumps.

g. New sump pump system.

h. Add overflow drain from surge pit to sump pit.

i. Provide new NSF-approved vacuum DE filter system, or change to pressure sand filters. Filter will be sized to match flow rate.

j. Connect new circulation systems to solar pool heating system.

k. Stainless steel or other corrosion-resistant materials used for pipe supports.

l. Configure the pool heating piping so that the solar heating and boiler heating are not in series.

3. Rewire the boiler shutoff switch to deactivate the boiler as well as the (2) gas water heaters.

C|4

Long-Term Recommendations:

4. Add in-ground hose bibb at west end of pool.

5. Replace the pool chemistry systems with gas CO2 and tablet chlorine feed systems that can be stored in the same space. Refurbish the exhaust fan system in the chemical storage room to ensure proper ventilation per the WAC requirements.

6. Provide new piping between the pool mechanical room & boiler room.

7. Replace the boiler with a new high-efficiency, sealed-combustion unit sized to prevent short-cycling.

Note: There was a question as to the appropriate cost for the boiler replacement, which we will attempt to address here.

First of all, we feel that the appropriate boiler for this facility and use should be a high-end condensing unit that can achieve 96-98% efficiency. Just the boiler itself retails for over $40,000. A lower cost unit that retails around $20,000 would only get a minimum code efficiency of 82-85%.

This cost difference will have an effect on the operational costs at the pool. A full analysis of that cost could be included as part of an engineering phase to validate the appropriate boiler during design.

Secondly, the costs we are estimating are the full stand-alone project costs. See the narrative on page A|7 for more detail.

Here’s the basis of design product for which we are basing this estimate, direct from a pool supplier:

http://www.lincolnaquatics.com/Heating+Systems+and+Accessories/Raypak+XTherm+2%2C000%2 C000+BTU+heater%2C+natural/product/21-670

8. Provide additional floor drainage in the restrooms.

GENERAL ELECTRICAL

On March 21, 2016, along with your design team I visited the site and toured the buildings reviewing the existing electrical service, interior/ exterior lighting and pool equipment connections.

Applicable Codes:

Washington State Administrative Code (WAC) 2014 National Electrical Code (NEC) 2015 International Building Code (IBC) 2015 International Fire Code (IFC) 2016 Washington State Non-Residential Energy Code (WSNREC)

EXISTING ELECTRICAL SERVICE

Electrical service, serving the pool building is underground from Puget Sound Energy (PSE) pole at the street. Within the existing electrical/ boiler room there is an existing, Square D, 120/208V, 3Ph, 4W, 225A main electrical panel “A”. This main electrical panel then serves the adjacent sub electrical panel “A” and pool equipment control panel located within the pool pump room. With the electrical/boiler room there are also three (3) contactor enclosures which serve pool floodlights, interior lights and exhaust fans.

The existing main and sub electrical panel “A” meet current electrical codes and have current circuit breaker models that are still readily available for replacement.

The existing contactor enclosures currently contain numerous contactors that have failed and should be replaced.

POOL EQUIPMENT ROOM

There is an existing pool equipment control panel located within the existing pool equipment control panel. Panel currently is operational, but will need to be replaced. The main breaker handle on the control panel is not operational and numerous control lights are not working. It appears that over time additional circuits have been tapped for equipment within the room that does not meet current electrical codes for tapping of conductors.

INTERIOR/ EXTERIOR BUILDING LIGHTING

Current interior building lights consist of 1’-0” x 4’-0”, 2-lamp, 32W, T8, fluorescent, surface mount fixtures and incandescent downlights. The fluorescent surface mount light fixtures have been recently upgraded with new lights and ballasts and are in working order.

Current exterior building mounted lights consist of 1’-0” x 4’-0”, 2-lamp, 32W, T8, fluorescent, surface mount fixtures mounted under roof overhangs at building entrances. The lenses on these fixtures have yellowed over time.

Front Parking Area Lighting The front parking area is currently lit from two (2) 12’ light poles with (3) floodlights on each pole located on each end of the building. This currently does not provide adequate lighting for the parking lot.

Pool Area Lighting The existing pool lighting currently consist of seven (7) exterior poles with 400W metal halide light fixtures mounted around the exterior of the pool walkway. Of the seven (7) light poles only two (2) are currently operational.

Hazardous material testing, handling, abatement and disposal.

Construction Costs, Contingencies and Markups The estimated costs are AREA OF MAGNITUDE type costs made by our team without design, based on available information.

Each cost heading, regardless of discipline, includes all costs for all disciplines to make a complete "stand alone" cost item.

Construction costs are based on industry standards with adjustments made by our team to correct to historic project costs .

Due to the schematic or preliminary nature of this type of report, a design contingency factor is included in estimated costs.

General contractor overhead and fees are assumed for a project of $100,000 or larger, smaller projects will increase these costs.

Contingencies & Contractor Markups are broken down as follows:

Design Contingency 20% Home Office Overhead 8% Site Overhead 10% General Contractor Fee 8% Project Location Factor 10% Bonds 1.50% Insurance 2.50% Sales Tax 9.50% General Markups Total 69.5%

Escalation to Future Dates As noted above, the pricing provided is at a early 2017 level. When projecting costs to future dates, a rate of 4% per year should be used to escalate the cost to the future date. This escalation factor is based on historical building costs as published by Engineering News Record. This rate varies month to month depending on economic conditions related to the construction industry.
