Community PreservaƟon CommiƩee Members Concerning
Proposed ModificaƟons to CPA and ARPA Work Scopes

October 20, 2023
This document is intended to be read as a narraƟve that helps to explain the scope of work and costs
provided in the Excel spreadsheet previously submiƩed to Somerville CPA and Somerville ARPA
administrators on October 6, 2023.
All of the work scope items for CPA FY21, FY22, FY23, and ARPA are listed in the far‐leŌ column of the
spreadsheet using CSI categories. Each work scope item is color‐coded to match the color code of the (7)
columns off to the right.
The work scope has not changed for CPA FY21 (light purple in Column ‘A’) and CPA FY22 (light blue in
Column ‘B’). The FY21 work includes the compleƟon of previously started brick masonry cuƫng,
repoinƟng and rebuilding of exisƟng brick masonry at the building cornice and spandrel panels.
The FY22 work scope includes essenƟal preparatory work for the ARPA elevator installaƟon, consisƟng
of foundaƟons and fooƟngs for the new hoistway and elevator pit. The ARPA work cannot begin unƟl
the hoistway foundaƟon and elevator pit have been designed and constructed. The primary General
Contractor for this work would be Cenaxo, LLC, who is also the G.C. for the FY21 work. Cenaxo has
previously completed substanƟal roofing and flashing improvements on the building.
The original work scope for CPA FY23 (green in Column ‘C’) has been moved to the far‐right column (light
warm gray in Column ‘G’) and idenƟfied as a future CPA grant program (perhaps FY25). This is a major
alteraƟon of a previously approved work scope.
The original CPA FY23 work scope focused on restoraƟon of the 2nd floor windows of the Kesher tenant
space, as well as the installaƟon of new storm windows. It also included guƩer and downspout
replacement along the north and south sides of the building, and addiƟonal brick masonry cuƫng,
repoinƟng, and parƟal rebuilding of the brick masonry denƟl cornice and spandrel panels
(supplemenƟng the same, but more limited work scope included in CPA FY21).
Column ‘E’ shows the proposed new work scope for CPA FY23, which now includes the concrete block
elevator hoistway (not the actual elevator), the copper‐clad, rooŌop elevator penthouse, and one of the
two new accessible restrooms. It also includes a $65,000 conƟngency. The elevator hoistway was
originally included in the original ARPA work scope. These adjustments of work scope were required due
to the significantly more expensive elevator and accessible restroom costs that were prepared by the
General Contractor for the proposed ARPA work scope (ZVI ConstrucƟon), which is shown in Column ‘D.’
Column ‘F’ shows the proposed work scope modificaƟons for the ARPA grant (in yellow). The ARPA work
is proposed to include the complete elevator equipment system, but not the CMU elevator hoistway (to
be constructed in the CPA FY22 work scope). It also includes funding for a substanƟal upgrade to the
exisƟng electrical service to the building, to provide adequate power for the new elevator. A conƟngency
of $90,000 is being carried in this column, which may be able to be used to build the second accessible
restroom.
The Somerville ARPA, CPA and HPC administrators have all agreed that the ARPA work scope should be
the primary focus of the work undertaken at the building. The enƟrety of the ARPA grant must be spent
by June 30, 2024. Adjustments to CPA work scope and funding should be reviewed with that goal in
mind.
The first goal of the proposed construcƟon (to successfully complete the ARPA scope of work by June 30,
2024) is to design and construct the elevator hoistway foundaƟon, fooƟngs and elevator pit that are
included in the CPA FY22 funding grant. This work will take place within the basement‐level Social Hall
and will require parƟal demoliƟon of the exisƟng basement slab, and some rock ledge removal to install
the hoistway elevator pit and foundaƟons.
A concurrent goal would be to work with NaƟonal Grid to increase the size of the current electrical
service to the building, which can be a long lead item. The new elevator cab and all related hardware
and equipment would also be ordered immediately, because it may have a lead‐Ɵme of approximately
37‐weeks. These two costs would be included in the ARPA grant amount. The actual installaƟon of the
elevator would be included in the FY23 work scope because the elevator installaƟon will probably be
completed aŌer June 30, 2024.
