Remedial Engineering Services

As building envelope engineers, CSG is typically called upon to address capital maintenance requirements or moisture intrusion issues. We usually perform more than 100 such projects per year and have executed this volume of work for more than 30 years. We are involved in designing repairs to constructed elements and features that are exposed to natural forces (wind, water, UV radiation, and temperature extremes) or kinetic forces (vehicle strikes). The elements and features we address most frequently include:

  • Roofing Systems & Features
  • Façades & Curtainwalls
  • Foundations
  • Balconies
  • Parking Structures
  • Loading Docks
  • Plaza Decks
  • Doors, Windows, & Skylights
  • Water Features (Ponds, Pools, & Fountains)
  • Retaining Walls

PROJECT PHASES


Phase I - Pre-Design Survey & Investigation

We conduct a site survey tailored to gather the data necessary to draw appropriate conclusions regarding existing conditions and to design a cost-effective solution. As a first step, we review any available building drawings and repair records. During the on-site portion of the investigation, necessary measurements and testing are conducted and documented. The process is memorialized in a report documented with photographs. The investigation report contains repair recommendations and alternatives, as well as preliminary budget estimates associated with each alternative.

Phase II - Design (Drawings & Specifications)

As circumstances dictate, we develop a code-compliant design that addresses the root causes of deterioration. We provide a permit-ready design (with a professional engineer's seal) that avoids cost and delay associated with questioning from the permit office. Where necessary, we assist the contractor with permitting issues. Our goal is to provide sufficient detail in the design to generate the lowest overall project cost. In this phase, we develop a comprehensive project budget.

Phase III - Bidding

We prepare comprehensive bid documents that enable us to evaluate pricing in multiple scenarios and compare it to construction schedules. This allows us to make confident and well-documented recommendations for award. We administer a pre-bid conference at the site to discuss the scope of work, specifications, project logistics, and any special client requirements.

CSG typically conducts the bid opening, tabulates the results, and presents the client with a letter of recommendation for the contractor selection with an explanatory rationale. Typically, this includes meeting with the client to review the results of the bidding and to make the contractor selection.

Preconstruction

Phase IV - Preconstruction

In the preconstruction phase, we review and negotiate the contract sum and unit prices with the selected bidder and develop the contract document (typically an AIA contract, augmented with any specific owner requirements). We then coordinate and conduct an on-site preconstruction conference, and subsequently prepare meeting minutes. We also review, negotiate, and approve contractor's Schedule of Values, and review and approve/reject contractor's certificates of insurance, bonds, submittals, and shop drawings.

Phase V - Construction Management & Quality Assurance

We provide oversight throughout the construction phase, acting as the client's representative on-site. This begins with coordinating the contractor's construction schedule and phasing of work, and reviewing the mobilization plans, general condition requirements, safety considerations, etc.

We then conduct regular on-site inspections to monitor progress and quality of the work. We prepare and submit field reports, documented with photographs, illustrating adherence of the work to the design and the construction materials' compliance with specifications. Each site visit is followed by a written inspection report detailing our observations, identification of problems, and any instructions issued to the contractor.

As necessary, we provide on-site field clarifications of design requirements and documentation of any guidance or changes. We review any "hidden" conditions revealed in the course of the construction process. We then review and negotiate, as required, any contractor requests for change orders.

Throughout construction, CSG coordinates and conducts regular progress meetings with the client and the contractor, and prepares and distributes written minutes for each meeting.

The progress of the work is tracked and documented with reference to the contractor's construction schedule; we note any deficiencies and recommend corrective actions required to maintain or recover the schedule. We coordinate site inspections for material manufacturer's representatives to ensure that contractor is complying with manufacturer's specifications and recommendations for application of the materials, as well as to verify the manufacturer will issue a warranty on the products.

We provide on-site quantity take-off verification of unit price quantities completed by the contractor. We offer regular budget updates of unit price quantities completed to date. We review the contractor's Applications for Payment and Lien Waivers and make payment recommendations for the client. We give updates and reconciliations on payments recommended to date with each application for payment.

At the conclusion of the project, CSG prepares a punch list and performs final inspections. We review all warranty documents, final clean-up, and final application for payment. Lastly, we develop a Project Close-Out Manual which includes copies of all important documents relating to the construction project.

Waterproofing Design Services

Waterproofing Design Services

CSG provides building envelope engineering services in the development (or redevelopment) phase of a real estate asset. We typically perform more than 20 such projects per year, and have done so for more than five years. Providing Development Services to Owners, Architects, and General Contractors is a core business of CSG. We assist these clients with design, construction, and post-construction phase services.



Design Phase Services

In the design phase we provide third party review of the building envelope design package and supplemental design. We examine the drawings and specifications for issues related to moisture permeability/resistance, construction materials compatibility, constructability, value engineering, suitability for the geographic location, O&M ease, and overall clarity of the design detail. We consult on energy code compliance and 3rd Party standards (e.g. LEED). We also recommend a construction phase testing regime to meet warranty requirements and industry standards.

Roofing systems:

  • Building façade / cladding / curtainwall
  • Foundations systems
  • Balconies and projections
  • Fenestration

Other asset features, including:

  • Plaza decks/terraces
  • Elevated walkways
  • Parking structures
  • Water features (indoor/outdoor)

 
The scope of our reviews typically address:

  • Waterproofing
  • Vapor barrier integrity
  • System selection and appropriateness
  • Insulation components
  • Building intersections
  • Drainage

Construction Phase Services


In the construction phase we are typically engaged to provide third party observation and QA services. In this role we generate a detailed written and photographic record of the materials installed and techniques employed during the construction process. This documentation can be particularly helpful when underground or concealed elements of construction come into question, particularly when verification or observation would require destructive examination and re-work.

Site visits are conducted by seasoned engineers who prepare written and photographic records of construction which are documented according to the location, date, time, and type. This documentation provides details of the building envelope-related activities, materials, and methods occurring on the jobsite during various phases of construction. Envelope-related Requests for Information from the construction contractor are similarly documented and incorporated into the record.
