]]>History has come alive at 25 Highland Avenue in Newton. Once the site of the late 19th-century 'Highland Villa' hotel, the building is now home to the Highland Ave Condos. It sits in the heart of the historic Newton Highlands district, renowned for its charming collection of late Victorian homes.
Challenges with the Brick Façade
During a previous project, a section of the brick veneer failed when a contractor removed a concrete landing to replace a set of stairs. The landing had been supporting the brick, and once removed, the masonry was compromised. BCG was brought in to perform a survey, which revealed that the brick was in poor condition—allowing water to penetrate the structure—and that the brick ties had all corroded and failed.
Choosing a Historically Accurate Restoration
Two options were considered: remove and rebuild the brick veneer or return the façade to its original wood siding. The client opted for the historically accurate approach: restoring the wood siding exterior. This solution addressed structural issues while honoring the building’s 19th-century charm, guided by old photographs to replicate the original design (minus the porches).
By removing the layers of brick to reveal the building’s original design, the project preserves its historic character. BCG takes pride in this restoration, combining the building’s historic charm with modern structural strength, keeping this historic building strong and vibrant for the future.

]]>Transition buildings’ was a term coined by post-transition historians that described the period when steel began to be utilized.
By Jeffrey S. Barnes, and Craig E. Barnes, P.E., S.E.
The term “transition building” was coined by post-transition historians. It derives from builders of that period utilizing steel to create greater building heights and floor spans. The word “skyscraper” had its origin in either New York or Chicago, but who holds bragging rights for the oldest skyscraper? Research suggests the oldest skyscraper is the 150-foot-tall Temple Court Building located in Manhattan and completed in 1883, while others declare Chicago had the first skyscraper—the Home Insurance Building, at 138 feet high, completed in 1885. Regardless of whether it is New York or Chicago for the home of the earliest skyscraper, one thing is certain—skyscrapers addressed a country that started booming socioeconomically and provided the need for more space.
Buildings transitioned from low-rise to high-rise seemingly overnight, and the technology had to keep up with the demand. Low-rise masonry structures grew to high-rise masonry structures that were load-bearing and could only be erected as quickly as the floors were constructed. In other words, the pace of building construction was, at times, directly linked to the pace of wall and floor construction. Thus, in colder climates such as Chicago, New York, and Boston, a high-rise could take 2 to 3 years to complete due to winter conditions. This was a costly and time-consuming process. Imagine being the owner of a 10-story masonry building and watching it take shape laboriously over a period of 2 to 3 years, maybe close to 4 years, before you can realize any return on investment.
But it was not just labor costs and time costs that drove technological advances: logistics also became a factor—material production (casting iron, firing bricks), fabrication (cutting steel to length, punching rivet holes), shipping, hauling (materials from railroad terminal to site) and placement (steel erection and bricklaying). In Boston, cement had to be brought in by train, which would add to the cost. Brick and stone required a large amount of space to fire and store prior to being used. As a result, that high-rise with a small footprint might have required 10 times its footprint of laydown space to be able to erect that high-rise, which added to the cost.
As demand for more space increased, the demand for the high-rise also increased, meaning more loads were introduced to the structure. As a result, masonry walls could no longer bear any more loads past a certain height. This is another reason why the steel frame came into play.
By the 1890s, three types of building technologies were available: bearing walls, cage frames (see sidebar), and skeleton frames. The bearing-wall building has thicker walls at the bottom and thinner walls at the higher sections of the building. This framing required interior masonry walls to support the floors above. The cage-framed building was a hybrid where the masonry walls provided lateral resistance to wind, and the steel frame directed gravity loads to the ground. The masonry walls in cage-framed buildings were slightly thinner than in bearing-wall buildings. Some interior masonry walls required for cage framing were replaced with cast iron columns. The skeleton-framed building had connecting steel beams and columns that supported the gravity and lateral loads; the masonry walls did not contribute much structurally and remained at a constant thickness from top to bottom. This concept is the precursor to today’s high-rise buildings.
Donald Friedman, president of Old Structures Engineering and a structural consultant in historic and old buildings, created a model to illustrate typical costs of the three types of building technologies available in the late 1890s. The models are 13 stories and do not include interior finishes, stairs, windows, or elevators; they are just the basic structure. Based on data for construction at that time, a 71 bearing-wall building may contain 4,900 tons of brick and 180 tons of steel for a bare structural cost of $122,000. A cage-framed building may require 2,600 tons of brick, 82 tons of cast iron, and 250 tons of steel for a bare structural cost of $80,000. A skeleton-framed building may need 1,800 tons of brick and 520 tons of steel for a bare structural cost of $74,000. As a building owner, opting for the more cost-efficient technology is a no-brainer and allows for a building with greater capacity than a bearing wall structure.
As the economy transitioned and began to grow, high-rise structures did, as well. These thinner buildings with smaller footprints allowed for a great number to be erected in a shorter amount of time and to greater heights as the country underwent rapid expansion, doubling the total cost of construction from $31.5 million in 1860 to $76.0 million in 1890. Builders were also transitioning in different ways as the building industry began to understand the benefits of rolled steel wide-flange sections, with a greater variety of shapes being provided.
Metals Used in Construction
Often confused but often not the same are wrought iron, cast iron, and steel. Wrought iron, with less than 0.1% carbon (mild steel) and less than 0.36% carbon (hard steel), is a commercial form of iron that is tough, malleable, and relatively soft for easy tooling. This form of wrought iron is often used in non-structural items such as tables and chairs. Cast iron, with a chemical content ranging between 2% -4% carbon and 1% -3% silica, is iron that has been melted, poured into a mold, and allowed to solidify. Cast iron, partially because of its poor tensile strength, is found more often in transitional structures as structural columns and cast as pintles. Pintles are frequently found in heavy timber construction, where they are used to transfer timber column loads at floor/ column joints. In addition, cast iron is very brittle, which makes it hard to shape or machine. Structural steel is an alloy or a combination of iron and other alloys such as carbon, manganese, nickel, copper, etc. To make the desired grade of steel, typically less than 2% carbon is added to iron, and the rest is made up of many other elements. When onsite, if you have any doubts about which material is present, strike the metals with a grinder, and the change in spark quantity will be the giveaway—the more spark, the higher the carbon content.
All iron ore-based products are produced through the process of smelting. The smelting process requires iron ore (of which there are different grades found in nature), coke, and limestone heated to melt the metal out of the ore. Young engineers should become familiar with the process. A familiar product that results from the smelting process is slag. Although largely a waste product, slag, which contains metal oxides and silicon, is improving its image as it is being used in a variety of highway products, including additives to concrete. Production smelting that engineers are familiar with originated in two- or more-story high vertical blast smelters that were shaped like an open-topped milk bottle and lined with refractory material (that resists high heat). The more efficient Bessemer converter superseded the vertical blast furnace, a larger, more rounded metal container lined with refractory material. This was replaced by the more efficient electric arc furnace, first utilized in France in 1907.
In the late 1800s and early 1900s, there were many small steel fabricators producing structural steel sections. These fabricators produced their own catalogs of available structural sections (Figure 1). Examples of these early fabricator catalogs are Wrought Iron & Steel 1884, Pencoyd Iron Works 1891, Carnegie, Phipps & Co.-1892, Bethlehem Steel pamphlet 1907, and the Bethlehem Steel blue book 1911. Another interesting tidbit is that steel at that time could have a 50 kips per square inch (ksi) ultimate tension strength and an Elastic Modulus of 30 ksi. Uniform safety factors were not universally accepted. One of the catalogs recommended railroad bridge members be designed to 1/5 of the ultimate steel value, highway bridges to 1/4 of the ultimate strength value, and roof trusses to 1/2 of the ultimate steel value.
In conclusion, this article barely scratches the surface of what transition buildings are and hopefully has interested the reader to continue their discovery.

]]>Thayer Academy Clock Tower
New England is blessed to have one of the deepest roots of history in our country that although beautiful to the eye, can be very costly and tedious to protect against changing weather and moisture. The clock tower of Thayer Academy is no such exception, and it is a statement piece of the this beautiful campus, located in the center of their courtyard.
The Thayer Academy Schoolhouse was first built in January of 1876. The Board of Trustees for the school held an architectural competition to choose the design. A firm by the name of Hartwell and Swazey won the competition and their design for the schoolhouse was chosen. The exterior of the school was completed by November and by August of 1877 the Academy was poised to open its doors for its first class.
Barnes Consulting was hired to repair the masonry that had damage caused by moisture and water intrusion on the brick façade. Brick and mortar naturally attract moisture which causes cracking and degradation over time. The Thayer Academy clocktower is made entirely of brick and mortar, making it a magnet for moisture and water problems that consistently needs to be addressed.
BCG was tasked with two issues, first, moisture was getting trapped in the interior of the clock tower that needed a way out. Inside the clock tower was a wooden staircase that leads up to the bell tower at the top. Within the front and side elevations, the tower has six “windows” of plexiglass that did not offer any ventilation for trapped moisture to escape. BCG suggested replacing the plexiglass “windows” with aluminum louvers (metal vents that look very similar to a window shudder) that offers air to flow in and out of the building and allow for moisture to escape during changing temperatures. This replacement not only will mitigate excessive moisture, but kept the historical charm of the building as well.
The second issue was the entire exterior needed masonry repairs consisting of cutting and pointing of the mortar joints, replacing damaged brick units, repairing stone elements and in some cases, replacing them, and replacing through-wall flashing at various locations. All these elements work together to mitigate water intrusion and to maintain the structural and architectural integrity of the clock tower, which is the main focus of the campus, and rightfully so.
The project is set to be completed by the start of the new school year, and we cannot wait until the scaffolding is down to see this iconic clock tower standing proud! Once finished, Thayer Academy will be left with a clock tower that will continue to stand proud and provide the beacon that the people of Thayer, and the Town know and love.

]]>St. John’s Episcopal Church, in Sandwich MA, the oldest church on Cape Cod, became a church in 1854 when nine citizens of the town of Sandwich gathered for the first time as a religious society. Almost 170 years later, the church continues to hold worship and prayer services for the community.
Even though St. John’s has been serving for so many years, they needed the help of Barnes Consulting Group to investigate and repair the rotting walls of their chancel; the space around the altar that includes the choir and the sanctuary. The damaged wood was due to water intrusion. Also, insufficient and clogged scuppers allowed unwanted water to enter the walls, causing significant rotting and structural issues.
BCG updated the scupper system and the counter flashing around the stained-glass windows. The new scupper design allows water to move through the parapet directly into the gutter below, so the roof can drain properly and avoid water intrusion behind the gutter and cedar shingle sheathing. BCG was also able to repair the rot and restore the exterior walls of the historic building back to its beautiful original character. The church is now back to “like-new” condition!

]]>When there is an accident or disaster, one of the questions everyone asks is “Who’s Fault is it?!”
Barnes Consulting (BCG) helps facilitate legal proceedings with their Expert Witness Services for building calamities. BCG will review the issue at hand, investigate, and provide an opinion report on what was the probable cause of the building damage. This report is almost always used in court as evidence to substantiate the claim. Occasionally, BCG’s senior engineer will appear in court as an expert witness.
One example would be the time BCG was hired to investigate a house that had been struck by a large truck in Springfield, Massachusetts. The impact was so great that it pushed the house 8 inches off of it’s foundation along with considerable damage to one side of the house. BCG was tasked with the determination of whether or not the house should be demolished and rebuilt, or could it be repaired.
BCG concluded that after fixing the foundation, moving the house back on to the foundation, the house could be repaired and demolition was not necessary.
So, we hope you never run into a situation like this BUT if you do, BCG is here to help you with forensic services… and expert witness testimony should it be required.
Point of View: the truck crashed into the house, causing significant damage to the kitchen

]]>2022 was a great year full of interesting projects for BCG. We were lucky enough to work on many historical buildings located in Massachusetts. Here we revisit five of our favorite historical project sites.
1. Charleston Lofts
The former Charleston Chew candy factory is now home to the Charleston Lofts in Everett, MA. The luxury condos feature exposed beams and brick. BCG was hired to perform a limited review of facades and water testing of windows. BCG found that window and door flashings and roof leaks needed to be repaired, as well as masonry issues that needed to be addressed. BCG then carried out the needed repairs.
2. The Edison Lofts
The Edison Lofts on Chauncy Street in Boston’s Financial District was constructed in 1890 as a warehouse for the Boston Edison Company. The building has been converted to modern luxury loft-style condos with exposed beams and bricks. BCG was tasked with repairing the façade, which came with many challenges. However, BCG was still able to help preserve this piece of history.
3. Crawford Court Condominium
The Crawford Court Condominium building is a 3-story, 75 unit, brick complex built in 1930. Located at 5 Crawford Street in Cambridge, it occupies the battle site of the Battle of Bunker Hill. BCG has been commissioned to restore the façade of the condominiums and to-date has refaced the brick and replaced rotted window headers.
4. St. Johns Episcopal Church
St. John's Episcopal Church became a church in 1854 when nine citizens of the town of Sandwich gathered for the first time as a religious society. BCG restored the interior walls of the historic building.
5. Thayer Academy Clock Tower
The Thayer Academy Clock Tower was constructed in 1876 on the Thayer Academy campus located in the heart of Braintree’s historic district. BCG has been working on the restoration of the clock tower since 2020.

]]>Concrete “Popcorn” Spalling: A High-level Explanation Almost every building construction project has concrete in it. During the placement phase, it’s important to complete specific steps to mitigate future issues – in this case, spalling. Concrete is one of the oldest construction materials on earth, having been around, in some form or other, for the past 2,000 years or so. In its basic sense, concrete is a combination of cement, aggregates, and water. When combined, they create a material that is great in compression, but not so great in tension. This is where the reinforcement comes in handy. Over time, the reinforcement in the concrete may become exposed to moisture due to various reasons – cracks caused by temperature changes, movement, improper installation, improper curing; or by improperly consolidating the concrete after it has been placed in the formwork. These deficiencies can cause a chain reaction of damage within the concrete and to the unprotected steel reinforcement. As an example, water seeps into cracks, freezes and expands to create larger cracks thus making the steel more susceptible to moisture. The example in the photo is one of improper concrete consolidation after the concrete has been placed. This “popcorn” spall so-called as the concrete surrounding the spalled areas can resemble popcorn. It can also be referred to as “honeycomb”. Once moisture reaches the unprotected steel the steel will start to rust which exacerbates the degradation of the surface, and the surrounding concrete, over time. Eventually, the rust build-up on the steel reinforcement will exert so much pressure on the surrounding concrete (through a process known as “rust-jacking”) that the concrete will continue to spall and deteriorate. Concrete spalling is a common problem BCG often deals with. There’s a number of solutions to consider but one thing is for certain, once you see ‘popcorn’ – you need to call Barnes ASAP!
