Taking a project off is the act of determining quantities that an estimator needs in order to determine a project estimate. The take off can be carried out by the estimator or a quantity surveyor and they are actually determining the quantities of the work that will be included in the overall scope. There are four types of measurements used to measure the full scope of work. The four are Count, Length, Area and Volume. Once you have completed the take off it is recommended that you visit the project site to better understand the site conditions and note any items that need risk pricing that is not clear from the bid document such as unforeseen items ie existing services or obstructions. Estimates are used for multiple reasons by the owner, builder, subcontractor and Architect from estimating if the design is appropriate for its intended purpose considering the cost to ensuring a project is in alignment with the owner's budget.

A Good estimate helps the team to improve its plans by highlighting errors or omissions before building has commenced, cutting costs by highlighting value engineering opportunities and identifying any gaps in trade packages or overlaps. Bid Comparisons are easier for the client to evaluate, Risk can be reduced when planning is carried out on an accurate cost estimate. There is less likely to be Change Orders if the cost estimate is detailed in its content. The costs included in the estimate do not include acquiring the land or furnishing a building as usually these are taken care of in the owners project cost estimate and asset valuation Contingencies and Variances are reserves builders will consider to cover unexpected conditions such as weather impact to productivity.

Equipment is usually rented, leased or amortized to over the cost of plant,machinery and equipment.Indirect costs Permit and inspection fees, administrative expenses, legal bills, overhead, insurance, security and utilities.

Professional Fees Quality of the specification will impact the cost depending if high, average or below average building categories.Other covers a wide range of items such as environmental remediation,demolition or government-mandated amenities such as parks and public artworks.

Estimators tend to work from top down ie start with the big picture then ADDMORE details as they progress or from the bottom up where they start with individual costs and then add them up.

ADDMORE Services follow the guidelines of the American Society of Professional Estimators ( ASPE ) Where the least reliable estimate is level 1 and the most accurate and reliable is level 5.

The names of these levels are known as Level 1 Order of Magnitude Level 2 Feasibility Level 3 Preliminary Level 4Substantive and Level 5 Definitive.

These levels are calculated by common methods

Level 1 Analogous, parametric, expert judgment and factoring.

Level 2 Parametric and Factoring

Level 3 Bottom up - unit cost assembly level

Level 4 Bottom up - unit cost detailed

Level 5 Bottom up - unit cost detailed

There is a simplified system of Construction Estimate classification by Accuracy and Phase.Design Estimates - Prepared during the project's pre-design and design phases it commences with an order of magnitude to evaluate if the project is viable.

Bid Estimates - These are prepared by contractors in efforts to win the project and are level 4 in terms of detail.

Control Estimates - These are the most accurate and include tender estimates,contract estimates and project controls estimates which are all at level 5 detail which are definitive estimates.The control estimate is prepared after an owner signs an agreement and before construction begins and is a baseline by which the actual construction costs are assessed and controlled.

This estimate enables the project's costs to completion to be determined and to plan and meet upcoming project costs. Another technique in construction project control is earned value analysis. This compares work completed to total planned work on various benchmarks including schedule and cost. The amount completed is calculated as a percentage of the planned to determine the earned value and to assess if the project is on time and on budget.

Performance vs Forecast at least 20% of the project must be completed before this estimate to completion can be properly applied.

Forecast to complete estimates includes more subjective considerations and predicts how much time and money the remainder of the project will cost including judgments about how the work will progress being aware of on the job site challenges already and anticipated to be faced.

Current working estimate, this estimate is the working budget and is evolving over the life of the project.

Preliminary estimating methods plus intermediate and final estimates. The preliminary estimate applies to cost forecasts produced in the planning and feasibility stages of a project and includes order of magnitude, feasibility and budget level estimates. Preliminary, Intermediate and final estimates equate to Design, bid and control estimates. Timing often dictates an estimator's choice of technique or level of accuracy.

Intermediate construction cost estimates are produced after design work is complete and costs are generally known.costs are broken down by project segments. Contingencies and Profit Margins are added to reach the total cost estimate.

Final Construction Cost Estimates are developed when all costs are known , construction has been out to tender and bids are received.

This estimate sets the contract value and definitive estimates mentioned previously are used.

Artificial intelligence has arrived in the built environment without much of an announcement. It is in the modelling software, in the document management platform, in the take-off tool, and in the email client. Most architecture and interior design practices are already using it several times a day, whether anyone has written a policy about it or not. So, the interesting question is no longer whether to use AI. It is what happens to the work once you do. The part of the story that gets left out Read almost anything written about AI and outsourcing this year and you will find the same quiet admission underneath the enthusiasm: none of it runs on its own. Somebody must prepare the information the system learns from. Somebody must look at what comes out the other end and decide whether it is right. The technology is genuinely impressive. It is also unaccountable on its own. That matters more in our sector than in most. A chatbot that answers a customer badly is an irritation. A model that produces a clash-free-looking coordination report on a badly set up federated model, or a take-off that quietly omits a whole material line, is a cost that lands on site months later, when it is expensive to fix and difficult to argue about. AI is very good at producing work that looks finished. Judging whether it is finished is a different skill, and it is not a technical one. It comes from having drawn the detail before, having priced the package before, having been on the receiving end of the RFI when it went wrong. What this looks like on a real project A Revit technician who understands how a model is meant to be structured can use automation to strip hours out of repetitive family creation, sheet setup and annotation, and spend the recovered time on the parts that need thought. A technician who does not understand the model will use the same tools to produce a great deal of tidy-looking rubbish, very quickly. An estimator with fifteen years behind them can run an automated material take-off, scan the output and know within a minute that the ceiling quantities are wrong because the tool has read a plenum as a room. The software will not flag that. Nothing in the output will look unusual. The estimator knows because they have seen a plenum before. The same holds for shop drawings, submittal review, document registers and coordination. In each case, the tool moves faster than a person could. In each case, someone must own the answer. What to actually look for If AI raises the value of judgement rather than lowering it, then the way firms buy resource ought to change with it. A few things are worth asking of anyone providing you with people: Can they scale up and down at the pace your workload genuinely moves, rather than at the pace of a twelve-month commitment? Do you know what you are paying and what you are getting for it, without unpicking a rate card? Do the people they provide work inside your systems, your file structure and your standards, or alongside them? And when something is wrong, is there a named person who is accountable for it? None of those questions mention AI. That is rather the point. The tools will keep changing. What protects the project is the quality of the person using them and the clarity of who answers for the output. Where ADDMORE sits We are not an AI company in the way that phrase is usually meant. We did not build a model and then go looking for somewhere to point it. We started from the work of documenting buildings, pricing packages and keeping projects moving, and everything we have built since has come out of that. What we provide is people, and the technology those people need to do the work properly. That means qualified back office professionals: 3D modellers, Revit and AutoCAD technicians, US estimators and document controllers, working as an extension of your own office, on your systems and to your standards. It also means business technology support: data engineers, analysts, BI specialists and AI engineers who build and maintain the automated parts of the workflow, the take-off routines, the document pipelines, the reporting behind the reporting. Done well, you never have to think about any of it. Done badly, it is the reason a number was wrong three months ago and nobody noticed. We also build software of our own, including PromoreIQ, our AI platform. We would rather tell you what a tool can and cannot do having had to make one work ourselves. Our people use AI in their daily work, and we expect them to. What we are providing, across all of it, is the experience that sits behind the output: the person who knows what the drawing is for, what the client will ask next, and what a plausible-looking result should have said instead. That is also why we have not rushed to relabel what we do. The work has not changed as much as the vocabulary around it has. Buildings still have to be documented properly. Packages still have to be priced accurately. Somebody still has to be answerable when they are not. The short version AI has made the first draft of almost everything affordable. It has not made the judgement inexpensive, and in the built environment, the judgement is where the risk lives. The firms that get the most out of these tools over the next few years will not be the ones with the largest technology budget. They will be the ones with enough experienced people to tell good output from bad, fast enough for it to matter. If you are working out how to add that capacity without adding overhead, we would be glad to talk it through.

The Hidden Advantage of Offshore Outsourcing: Why Broader Talent Pools Lead to Better Results When businesses talk about offshore outsourcing, the conversation often starts with two familiar topics: cost savings and time zones. Both are important. But they are not what ultimately determine whether an offshore engagement delivers meaningful value. The bigger question is much more fundamental: Are you accessing the right talent in the first place? A broader talent pool, a fair approach to evaluating capability, and a genuine understanding of local professional markets can have a significant impact on the quality of offshore work. This is especially relevant for industries where technical knowledge, consistency, communication, and attention to detail directly affect project outcomes. For companies exploring offshore outsourcing, the opportunity is not simply to reduce operating costs. It is to access capabilities that can strengthen the way work gets done. Offshore Outsourcing Is About More Than Cost Cost efficiency is one of the most obvious advantages of offshore outsourcing. However, focusing exclusively on cost can lead businesses toward the wrong question. Instead of asking: "How much can we save?" It can be more valuable to ask: "What additional capability can we access?" A lower-cost resource does not automatically create a better business outcome. If the work requires excessive supervision, frequent corrections, or repeated revisions, the initial savings can quickly be offset by lost time and reduced productivity. The strongest offshore models focus on value rather than price alone. That means identifying professionals with the right technical capabilities, evaluating them against the actual requirements of the work, and creating an operating environment where those capabilities can be used effectively. A Broader Talent Pool Creates Better Opportunities One of the major advantages of offshore outsourcing is geographic access to talent. Clients that work with trusted professional and technical AEC support services who have access in regions such as the Philippines, LATAM, and other global talent hubs gain access to a wider pool of professionals with diverse educational backgrounds, varied project experience, strong technical capabilities, and broader perspectives. Organizations that achieve stronger results are not simply moving fast or chasing the lowest cost. They succeed because they tap into a broader talent landscape and use more rigorous, meaningful methods to assess capability. This is particularly important when the work requires specialized knowledge. For example, an AEC company looking for additional support with drafting, BIM production, quantity takeoffs, documentation, or other technical functions may benefit from looking beyond its immediate geographic market. The objective is not to find more people. It is to fin d more of the right capabilities. Why the Quality of Evaluation Matters Expanding the talent pool is only part of the equation. How professionals are evaluated matters just as much. Traditional hiring and sourcing processes can sometimes place too much emphasis on familiar credentials, recognizable companies, conventional career paths, or whether a candidate appears to fit a predetermined profile. These indicators can be useful, but they do not always demonstrate how well someone can actually perform the work. A more effective approach is to focus on demonstrable capability. Depending on the function, that could include evaluating: Technical knowledge Relevant industry experience Problem-solving ability Attention to detail Communication skills Ability to follow established processes Software proficiency Practical application of knowledge Ability to work independently Consistency and quality of output For technical industries, this distinction is particularly important. A professional who can demonstrate the ability to produce accurate work may ultimately provide more value than someone whose profile simply looks impressive on paper. Inclusive Evaluation Can Improve Offshore Outcomes Inclusive evaluation can meaningfully strengthen offshore outcomes. While inclusive hiring is often framed as a cultural initiative, it also carries a practical business advantage. When companies expand their talent search and assess candidates based on demonstrated capability, they open the door to a wider pool of qualified professionals, including individuals whose strengths might otherwise be overlooked. This matters even more in offshore outsourcing, where geographic reach already exposes organizations to diverse professional markets. The opportunity is to make that access count by avoiding narrow assumptions about what a strong candidate should look like. A broader talent map, paired with fair, capability‑focused evaluation, creates a stronger and more reliable foundation for offshore delivery. Local Market Understanding Makes a Difference Offshore outsourcing is not simply a matter of selecting a country and searching for available professionals. Every market has its own professional environment, educational systems, compensation expectations, talent concentrations, and working practices. Understanding those differences matters. The value of working with organizations that understand the local market rather than relying exclusively on databases or generic sourcing methods is not to be overlooked. For businesses, this can mean better alignment between the capabilities they need and their trusted intelligent resourcing anwith knowledge and access to pre-vetted professionals available in a particular location. It can also help create more realistic expectations around communication, workflows, professional development, and the type of work that can be effectively delivered offshore. The AEC Industry Has a Particularly Strong Opportunity For the architecture, engineering, and construction industry, offshore outsourcing can extend far beyond basic administrative support. AEC businesses frequently deal with fluctuating workloads, demanding project schedules, specialized documentation requirements, and resource-intensive production work. Access to a broader pool of technical professionals can provide additional capacity in areas such as: Architectural drafting BIM and Revit production Construction documentation Shop drawings Quantity takeoffs Material schedules Cost management support Rendering and visualization MEP and structural documentation Project administration The value comes from connecting these capabilities with the right workflows and quality standards. This is why the quality of the offshore professional matters just as much as the cost structure. Offshore Capability Should Complement Your Existing Operations A successful offshore model should not feel disconnected from the business it supports. The objective is to create an effective extension of existing workflows. That requires clear processes, defined deliverables, appropriate quality control, effective communication, and a shared understanding of project expectations. For an AEC organization, this might mean having offshore professionals support production documentation while project leadership, design decisions, client relationships, and critical approvals remain within the primary business. The result is not simply outsourced labor. It is additional professional capacity integrated into the way the business already operates. How ADDMORE Approaches Offshore Outsourcing At ADDMORE Services LLC, our focus is on helping AEC organizations access professional offshore capabilities Solutions that can support their technical and operational requirements. Rather than positioning offshore outsourcing purely as a cost-cutting exercise, ADDMORE approaches it as an opportunity to add specialized capability where it can create measurable value. Our offshore professionals support areas including architectural documentation, BIM and Revit production, engineering drawings, quantity takeoffs, cost management, rendering, Sales and Operations and other AEC-related services The objective is straightforward: Give AEC businesses access to capable professionals who can contribute to their existing workflows while helping them manage capacity, productivity, and project demands more effectively. This approach also reflects an important principle from the broader offshore outsourcing conversation: the quality of the result depends heavily on the quality of the people performing the work and the process used to identify and evaluate those capabilities. Rethinking the Offshore Outsourcing Conversation The offshore outsourcing conversation does not need to stop at: "How much can we save?" A more strategic conversation asks: What capabilities do we need? Where can we access those capabilities? How broad is the available talent pool? How are professionals being evaluated? Are we measuring actual ability or simply reviewing credentials? Does the offshore operation understand our industry? Can the work integrate effectively with our existing processes? Will the additional capacity improve our ability to deliver? These questions lead to a different understanding of offshore outsourcing. It becomes less about finding the cheapest option and more about expanding access to capability. The Real Advantage Is Access The hidden advantage of offshore outsourcing is not simply geographic distance or lower operating costs. It is access . Access to a broader professional market. Access to specialized skills. Access to additional production capacity. Access to different perspectives and experiences. And, when the process is designed properly, access to professionals who can contribute meaningful value to the work being delivered. For companies willing to look beyond the traditional boundaries of recruitment and resourcing, a broader talent pool can become a genuine competitive advantage.
