Dear Potomac Elementary School Community:

I am writing to provide an update on the time line for the Potomac Elementary School Revitalization/Expansion project. As we shared with you last school year, project delays resulted in the need to revise the construction time line with potential move-in dates of either spring break or summer 2020, rather than the initial time line of winter break next year. We have done everything we can to accelerate the construction project, but after consulting with our external construction firm, internal project manager, and Dr. Catherine Allie, we believe the prudent course of action is to establish summer 2020 as the new final completion date for the project.

We sincerely regret this extended project delay.  This completion date will allow for contingency time should inclement weather continue to impact the project over the course of the next school year as it has thus far.   While project delays are not the norm in Montgomery County Public Schools construction, changing circumstances can impact the construction project plan and from time to time it becomes necessary to change the completion date.  As a result, Potomac Elementary School will continue to operate without interruption at the Radnor Holding Center until the end of the 2019-2020 school year. 

We anticipate that the new Potomac Elementary School will be ready for use in late spring for special events.  We will work with Dr. Allie to coordinate any events and activities in the new facility once it is available, but we wanted you to know now the determination of the new final completion date.   

We appreciate your patience and flexibility throughout the construction process.  We look forward to bringing you a new school facility that will serve the Potomac Elementary School community for many years to come.

Sincerely,

Andrew M. Zuckerman, Ed.D.

Chief Operating Officer

 April, 2019 Update:  The grading of the stream has been completed and stream channel has been stabilized with Sod. Mechanical, electrical and plumbing rough-ins have been completed. The concrete slab on grade was poured. All above ground utility work along river road has been relocated and the temporary storm water traps have been installed and inspected . Looking ahead: The crane is mobilized and steel is being erected. The steel decking and roof joist are being installed.  Electrical, Mechanical and plumbing contractors are performing concrete deck rough-ins.  The concrete deck is scheduled to be poured at the end of April. The temporary storm water traps have been installed and inspected which has allowed the contractor to begin the removal of the existing concrete slab on grade. The area will be graded once the concrete debris has been removed. Footings and foundations will begin during the first part of May. The 66" water line material has been fabricated and the replacement work is scheduled to start the second week of April.  WSSC has shut down the 66" water line and are preparing to de-water the line. The site contractor will also install the sanitary and 8" water lines that feed the school. There will be some temporary traffic pattern changes along the front of the school during the 66" water line replacement.  The change in traffic pattern will last until June 2019.

March, 2019 Update:   The bridge abutments and retaining walls inside the stream are complete.  All initial storm water piping and storm structures are also complete. The grading of the stream area continues. Pepco is continuing to work on the transfer of utilities on the new power poles along River Road. Looking ahead, we are scheduled to pour concrete slab on March 15th. The remaining utilities (Verizon, Comcast, county fiber) on the power poles will be transferred to new poles. The crane will be mobilized and set up to start steel erection. The 66" water line replacement work is scheduled to start around the first week of April. There will be some temporary traffic pattern changes along the front of the school during the 66" water line replacement process.

February, 2019 Update:  The site contractor continues to install storm water structures and temporary inlets which will allow the contractor to grade for the stream.  The addition of the stream was a request by Montgomery National Capital Park and Planning Commission (MNCPPC) in lieu of installing storm piping underground. 

1. Bridge abutments over stream (for small pedestrian bridge to access back fields) to begin this week

2. Building - Area B footings and foundations continue.  

3. Building- Underground electric and plumbing rough-ins to start in Area B. 

4. Construction cannot continue on other parts of the building until stream is built and soil stabilized. 

Pepco work on front high power lines continues despite missing dates to complete work.  A main switch has to be replaced and other utilities relocated once high voltage power lines have been relocated.  

 WSSC  will hold pre-construction meeting this week to discuss 66" water line replacement and sewer and water lines for school.  Water line replacement to start in mid to late April 2019 pending any shutdown issues.  

January, 2019 Update: The contractors continue to install erosion and sediment control measures at the school site. On January 14th, part of the existing concrete slab will be removed  and a partial building pad will be established with footings. MCPS continues to work with WSSC on the joint venture to replace the existing 66" water line and with Pepco to relocate power poles to front of the school. Keller, the construction manager, is working with the contractors to mitigate delays due to the Forest Conservation plan details and associated county planning permits. 

December, 2018 Update from the Division of Construction: The Erosion and sediment control permit has been issued. Park and Planning and DPS (Department of Permitting services) will meet to start the initial sediment control measures. There will be Super Silt fence and underground storm piping installed within the next month.  Coordination with WSSC and Pepco, utility poles at the front of the school will be relocated prior to the start of the WSSC work on the 66" water line in December, weather permitting.   The school footings and foundations will start in January. 

 

 Stage 1:  DESIGN

We are currently in the design stage.  Four meetings have been held to get feedback on a range of proposed designs.  The meeting collected feedback and suggestions on potential improvements and pros and cons.  Three different feasible concepts have been presented.

o   A complete tear down and rebuild (students off-site)

o   A partial tear down and rebuild (students off-site)

o   Construction while occupied (students on-site). 

Next steps will be to schedule an additional meeting for the architect to present options that improve previous concepts or develop new concepts based on the feedback received. Additional meetings are likely to be scheduled in late February and early March. 

The architect will present and outline all pros and cons and narrow in on the concept that will solve as many design goals as possible. 

MCPS Superintendent, Dr. Smith has asked the MCPS team to explore the feasibility of a same sight construction project.

 

 Stage 2:  PROGRAM IMPLICATIONS

While we know there is an interest in learning more about bell times, transportation schedules, recess, lunch, arrival/dismissal, and other factors related to the holding school, the design meetings are not intended to explore those particular issues. If you have questions about the implications to the instructional program based on same site or off site project locations, please let us know.  

To offer some preliminary information about Radnor and to address some of the questions that have been raised.  Please see general facility information below. 

o   Number of classrooms in the building: 16

o   Total square footage: 36, 663 (Compared to 57,713 at Potomac)

o   Site size 9.03 acres (Compared to 9.6 acres at Potomac)

o   Number of relocatable classrooms currently: 23* (Some may be removed if needed elsewhere)       

Before and After Care:   MCPS staff have spoken to the current before and after care service provider regarding the Radnor center option.  They said if they are still on contract during the modernization they would not only extend operational hours to accommodate parents but also bus students to a closer facility if that was preferred.
