WHS feasibility study moving forward

By Evan MacDonald/emacdonald@wickedlocal.com

Winchester, MA — Academic programming, a site analysis and a facilities assessment for the Winchester High School feasibility study are underway and should be completed by the end of the summer, architectural firm Symmes Maini & McKee Associates told the School Committee on Tuesday night.

The firm expects to complete an interior assessment of the existing facility and an overall analysis of the current site on Skillings Road in the next few weeks, said Edward Frenette, a senior vice president for Symmes.

The programming part of the feasibility study involves looking at a school’s curriculum—such as math, science, and literature—and determining the amount and type of space that will be required to teach those subjects.

The basic academic programming analysis—which looks at core classes—is 90 percent complete and should be finished in a few weeks, Frenette said.

The firm is about 30 percent done with its review of the school’s unique academic programming—which considers spaces needed for other kinds of uses such as aerobics, dance or group instruction.

“We’re just looking at the curriculum in general, and how it translates to the type and number of spaces that will be required,” Superintendant of Schools William McAlduff said. “We’re not looking at individual course needs yet.”

The goal is to design a modern facility without making too many assumptions about the future of education, Frenette said.

“We’re very careful about leading our clients to the next step or the step after that, but we’re also careful about not leading them too far,” he said. “It’s our job to push you where we think you need to be pushed, but also to pull you back when we think you’re going too far.”

Designing a building that’s adaptable will help the district deal with educational changes in the future, School Committee member Sarah Swiger said.

“It’s impossible to know where education is going to be in 40 or 50 years,” Swiger said. “So it’s important to have flexible space.”

Four alternative sites also are being considered for a new WHS, pursuant to a requirement by the Massachusetts School Building Authority (MSBA). Those alternatives are: the Winchester Parks Department site on the Medford town line, Lynch School, Skillings Field and Wright-Locke Farm.

Two of those options may be eliminated over the next few weeks based on legal issues, availability and other restrictions, Frenette said.

The feasibility study project, which includes examining WHS and developing options for renovating the current building or constructing a new facility, officially began in March and is expected to continue until July 2013. The town must submit a preferred construction option to the MSBA by late 2012 for approval. A final design is expected to be ready in time for a Fall 2013 Town Meeting vote to approve funding for construction.

The next public meeting on the WHS project is Sept. 12 at 7 p.m. in the WHS auditorium. Copyright 2012 The Winchester Star. Some rights reserved
